- Version 1.0.67.0 August X, 2010
- Using SQLite 3.7.0.1
- Written by Robert Simpson (robert@blackcastlesoft.com)
- Released to the public domain, use at your own risk!
- Official provider website:  http://sqlite.phxsoftware.com
-
- The latest version can be downloaded - here -
-
- -

- Features:
-

-
    -
  • - Written from scratch on VS2008 specifically for ADO.NET 2.0, implementing all the - base classes and features recently introduced in the framework, including automatic - transaction enlistment.
  • Supports the Full - and Compact .NET Framework, and native C/C++ development.  100% binary - compatible with the original sqlite3.dll.
    • -
  • Full support for Mono via a "managed only" provider that runs against the - official SQLite 3.6.1 or higher library.
    • -
  • Full Entity Framework support (ADO.NET 3.5 SP1)
    • -
  • - On the Compact Framework, it is faster than Sql Server - Mobile. SQLite's installed size is a fraction of Sql Mobile's. It uses less memory at runtime, runs queries faster, and has a smaller database file size as well. -
  • Encrypted database support.  Encrypted databases are fully encrypted and - support both binary and cleartext password types.
    • -
  • - Visual Studio 2005/2008 Design-Time Support, works with all versions of VS2005/2008, - including - all Express Editions of VS2005.  You can add a SQLite - database to the Servers list, design queries with the Query Designer, - drag-and-drop tables onto a Typed DataSet, etc.
  • - Full SQLite schema editing inside Visual Studio.  - You can create/edit tables, views, triggers, indexes, check constraints and foreign keys.
  • - Single file redistributable (except on Compact Framework).  The core sqlite3 codebase and the ADO.NET wrapper - are combined into one multi-module assembly. -
  • - Binaries included for Itanium, x64, x86 and ARM processors.
  • - DbProviderFactory support. -
  • - Full support for ATTACH'ed databases.  Exposed as Catalogs - in the schema.  When cloning a connection, all attached databases are - automatically re-attached to the new connection. -
  • - DbConnection.GetSchema(...) support includes ReservedWords, MetaDataCollections, DataSourceInformation, - DataTypes, Columns, Tables, Views, ViewColumns, Catalogs, Indexes, - IndexColumns, ForeignKeys and Triggers. -
  • - Enhanced DbDataReader.GetSchemaTable() functionality returns catalog, namespace - and detailed schema information even for complex queries. -
  • - Named and unnamed parameters. -
  • - Full UTF-8 and UTF-16 support, each with optimized pipelines into the native - database core. -
  • - Multiple simultaneous DataReaders (one DataReader per Command however). -
  • - Full support for user-defined scalar and aggregate functions, encapsulated into - an easy-to-use base class in which only a couple of overrides are necessary to - implement new SQL functions. -
  • - Full support for user-defined collating sequences, every bit as simple to - implement as user-defined functions and uses the same base class. -
  • - Full source for the entire engine and wrapper.  No copyrights.  - Public Domain.  100% free for commercial and non-commercial use. 
- -

- Design-Time Support

-

- In Windows Explorer, navigate to the SQLite.NET\bin\Designer - folder and execute the INSTALL.EXE - file.  The program will - automatically detect what version(s) of Visual Studio 2005/2008 are installed and allow - you to selectively install and uninstall the designer for each edition.

-

DbFactory Support (Non-Compact Framework)

- In order to use the SQLiteFactory and have the SQLite data provider enumerated - in the DbProviderFactories methods, you must add the following segment into your application's app.config file:
-
- 
<configuration>
-  <system.data>
-    <DbProviderFactories>
-      <remove invariant="System.Data.SQLite"/>
-      <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite"
 type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />
-    </DbProviderFactories>
-  </system.data>
-</configuration>
-
-

See the help documentation for further details on implementing both version-specific (GAC enabled) and version independent DBProviderFactories support. -

-

- Compiling for the Compact Framework

-

- Just change the target platform from Win32 to Compact Framework and - recompile.  The Compact Framework has no support for enumerating - attributes in an assembly, therefore all user-defined collating sequences and - functions must be explicitly registered.  See the testce - sample application for an example of how to explicitly register user-defined - collating sequences and functions.

-

- Distributing The SQLite Engine and ADO.NET Assembly

-

- On the desktop, only the System.Data.SQLite.DLL file needs to be distributed with your - application(s).  This DLL contains both the managed wrapper and the native - SQLite3 codebase.  For the Compact Framework, you will have to distribute - both the CF version of System.Data.SQLite.DLL, as well as the - SQLite.Interop.XXX.DLL.  This is a breaking change as of 1.0.59.0.  - Recent Windows Mobile frameworks are not supporting the mixed CF assembly I was - building prior to this version.

-

Development Notes Regarding the SQLite 3 Source Code

-

- The core sqlite engine is compiled directly from the unmodified source code available - at the sqlite.org website.  Several additional pieces are compiled on top of - it to extend its functionality, but the core engine's source is not changed.

    • -
  • Added "bigint" to the dropdown in the table designer, plus other minor table - designer bugfixes.
    • -
-

1.0.64.0 - July 9, 2009

-
    -
  • Fixed the missing resources problem from the 63 release.
    • -

    • -
-

1.0.63.0 - June 29, 2009

-
    -
  • Code merge with SQLite 3.6.16
    • -
  • Check the autocommit mode of the connection to which a transaction is bound - during the disposal of the transaction.  If autocommit is enabled, then the - database has already rolled back the transaction and we don't need to do it - during dispose, and can quietly ignore the step without throwing an error.
    • -
  • Eliminated the mergebin step altogether.  It was developed primarily to - merge the Compact Framework binaries together, but since we're not doing that - anymore, its use is limited.  Its non-standard method of merging a binary - on the desktop framework is redundant as well.  The desktop binary now - hard-links to MSCOREE, but as of Windows XP, this was redundant as well since XP - and beyond automatically attempt to load MSCOREE on startup when a DLL has a - .NET header.
    • -
  • More improvements to the test.exe program for running the tests against Sql - Server for comparison purposes.
    • -
-

    • -
  • Several changes to the Test program that comes with the provider.  Tests - can now be individually disabled, and the test program can run against several - provider back-ends
    • -
-

1.0.61.0 - April 28, 2009

-
    -
  • Code merge with SQLite 3.6.13. The new backup features are as yet unimplemented in the provider, but will be forthcoming in a subsequent release
    • -
  • Fixed the default-value lookups in SQLiteConnectionStringBuilder when accessing properties
    • -
  • Lock the SQLiteTransaction object during dispose to avoid potential race condition during cleanup
    • -
  • Fixed SQLiteDataReader.GetDecimal() processing and parsing of decimal values for cases when SQLite returns things like "1.0e-05" instead of "0.0001"
    • -
-

1.0.60.0 - October 3, 2008

-
    -
  • Throw a NotSupported exception in the EF Sql Gen code instead of parsing - illegal SQL during an update/insert/delete where no primary key is defined.
    • -
  • Fixed the Compact Framework interop library.  Since the linker flag - /subsystem had no version specified, it was causing a problem for many CE-based - platforms.
    • -
  • Incorporated SQLite patch for ticket - #3387 and reverted - out the vfs override code I added in build 59 to work around this problem.
    • -
  • Fixed a designer issue when creating a new table from the Server Explorer.  - After initially saving it, if you then continued to edit it and tried to save it - again, it would generate the change SQL using the old temporary table name - rather than the new name.
    • -
-

1.0.59.0 - September 22, 2008

-
    -
  • Code merge with SQLite 3.6.3.  Solves - a couple different EF issues that were either giving inconsistent results or - crashing the engine.
    • -
  • Fixed the parsing of literal binaries in the EF SqlGen code.  SQLite now - passes nearly all the testcases in - Microsoft's EF Query Samples application -- - the exception being the datetimeoffset and time constants tests, and tests - that use the APPLY keyword which are unsupported for now.
    • -
  • Revamped the Compact Framework mixed-mode assembly.  Tired of playing cat - and mouse with the Compact Framework's support for mixed-mode assemblies.  - The CF build now requires that you distribute both the System.Data.SQLite - library and the paired SQLite.Interop.XXX library.   The XXX denotes - the build number of the library.
    • -
  • Implemented a workaround for Vista's overzealous caching by turning off - FILE_FLAG_RANDOM_ACCESS for OS versions above XP.  This is implemented - as a custom (default override) VFS in the interop.c file, so no changes are made - to the SQLite source code.
    • -
  • Fixed some registry issues in the designer install.exe, which prevented some - design-time stuff from working on the Compact Framework when .NET 3.5 was - installed.
    • -
-

1.0.58.0 - August 30, 2008

-
    -
  • Code merge with SQLite 3.6.2.  If only I'd waited one more day to release - 57!  Several LINQ issues have been resolved with this engine release - relating to deeply-nested subqueries that the EF SqlGen creates.
    • -
  • The Rollback SQLiteConnection event no longer requires an open connection in - order to subscribe to it.  Missed this one in the 57 release.
    • -
-

1.0.57.0 - August 29, 2008

-
    -
  • Compiled against 3.6.1 with checkin - #3300 resolved, - which fixes an Entity Framework bug I was seeing.  I currently have 3 other - tickets out on the engine, which are not yet resolved and relate to EF.
    • -
  • Fixed decimal types to store and fetch using InvariantCulture.  If you're - using decimal datatypes in your database and were affected by the 56 release, - please issue an UPDATE <table> SET <column> = REPLACE(<column>, ',', '.');  - to fix the decimal separators.  Apologies for not testing that more - thoroughly before releasing 56.
    • -
  • Too many LINQ fixes to list.  Fixed views so they generate, - fixed the LIMIT clause, implemented additional functionality and removed unnecessary code.
    • -
  • Fixed foreign key names in the designer so viewing the SQL script on a new - unsaved table after renaming it in the properties toolwindow will reflect in the - script properly.
    • -
  • Fixed the Update and Commit events on SQLiteConnection so they don't require - the connection to be opened first.
    • -
  • Fixed userdef aggregate functions so they play nice with each other when - appearing multiple times in the same statement.
    • -
  • Fixed the editing and saving of default values in the table designer.
    • -
  • Fixed ForeignKeys schema to support multi-column foreign keys.  Also - hacked support for them in the table designer, provided two foreign keys in the - designer have the same name and reference the same foreign table and different - columns.  Will implement first-class support for this in the next release.
    • -
-

1.0.56.0 - August 11, 2008

-
    -
  • Fixed a bug in the table designer when designing new tables, wherein you had to - save the table first before being able to create indexes and foreign keys.
    • -
  • Tweaks to decimal type handling.  The 'decimal' type can't be represented - by Int64 or Double (without loss of precision) in SQLite, so we have to fudge it - by treating it like a string and converting it back and forth in the provider.  - Unfortunately backing it to the db as a string causes sorting problems.  - See this - post - for details on using a custom collation sequence to overcome the sorting issue arising from this patch.
    • -
  • Minor tweaks and bugfixes to the test program and the provider.
    • -
  • More adjustments to make the managed-only version of the provider run and pass - all tests on Mono.
    • -
  • LINQ to Entities bits heavily updated and compiled against VS2008 SP1 RTM.  SQLite - LINQ support is still considered beta.
    • -
-

1.0.55.0 - August 6, 2008

-
    -
  • Code merge with SQLite 3.6.1
    • -
  • Added support for the user-contributed extension-functions at - http://www.sqlite.org/contrib.  - Feel free to override any of them with your own implementation.  The new - functions are: acos, asin, atan, atn2, atan2, acosh, asinh, atanh, - difference, degrees, radians, cos, sin, tan, cot, cosh, sinh, tanh, coth, exp, - log, log10, power, sign, sqrt, square, ceil, floor, pi, replicate, charindex, - leftstr, rightstr, reverse, proper, padl, padr, padc, strfilter, and - aggregates stdev, variance, mode, median, lower_quartile, upper_quartile.
    • -
  • Moved the last_rows_affected() function to the C extension library.
    • -
  • Added a new class, SQLiteFunctionEx which extends SQLiteFunction and adds the - ability for a user-defined function to get the collating sequence during the - Invoke/Step methods.  User-defined functions can use the collating sequence - as a helper to compare values.
    • -
  • When registering user-defined collation sequences and functions, the provider - will now register both a UTF8 and a UTF16 version instead of just UTF8.
    • -
  • Revamped connection pooling and added static ClearPool() and ClearAllPools() - functions to SQLiteConnection.  Behavior of the pool and its clearing - mechanics match SqlClient.
    • -
  • Fixed connections going to the pool so that any unfinalized lingering commands - from un-collected datareaders are automatically reset and any lurking - transactions made on the connection are rolled back.
    • -
  • Transaction isolation levels are now partially supported.  Serializable - is the default, which obtains read/write locks immediately -- this is compatible - with previous releases of the provider.  Unspecified will default to - whatever the default isolation mode is set to, and ReadCommitted will cause a - deferred lock to be obtained.  No other values are legal.
    • -
  • Revamped the test.exe program.  It's now an interactive GUI application.  - Easier for me to add tests now.
    • -
  • Tweaks to the VS designer package and installer.
    • -
  • More adjustments to the internal SQLite3.Prepare() method to account for both - kinds of lock errors when retrying.
    • -
  • Stripped a lot of unnecessary interop() calls and replaced with base sqlite calls.  - Revamped most of UnsafeNativeMethods to make it easier to port the code.
    • -
  • Rerigged internal callbacks for userdef functions and other native to managed - callbacks.  More portable this way.
    • -
  • Source can now can be compiled with the SQLITE_STANDARD preprocessor symbol to - force the wrapper to use the stock sqlite3 library.  Some functionality is - missing, but its minimal.  None of the precompiled binaries are compiled - using this setting, but its useful for testing portability.
    • -
  • Added "boolean" and a couple other missing datatypes to the "DataTypes" schema - xml file.  Used by the VS designer when displaying tables and querying.
    • -
  • Added a new connection string option "Read Only".  When set to True, the - database will be opened in read-only mode.
    • -
  • Added a new connection string option "Max Pool Size" to set the maximum size - of the connection pool for a given db file connection.
    • -
  • Added a new connection string option "Default IsolationLevel" to set the - default isolation level of transactions.  Possible values are Serializable and - ReadCommitted.
    • -
  • Added a new connection string option "URI" as an optional parameter for - compatibility with other ports of the provider.
    • -
-

1.0.54.0 - July 25, 2008

-
    -
  • Fixed the setup project, which somehow "forgot" to include all the binaries in - the 53 release.
    • -
  • Fixed a crash in the table designer when creating a new table and tabbing past - the "Allow Nulls" cell in the grid while creating a new column.
    • -
  • Fixed a mostly-benign bug in SQLiteDataReader's GetEnumerator, which failed to - pass along a flag to the underyling DbEnumerator it creates.  This one's - been around since day 1 and nobody's noticed it in all these years.
    • -
  • Added a new connection string parameter "Journal Mode" that allows you to set - the SQLite journal mode to Delete, Persist or Off.
    • -

  • Enabled sqlite_load_extension
    • -
  • Added retry/timeout code to SQLite3.Prepare() when preparing statements for - execution and a SQLITE_BUSY error occurs.
    • -
  • Added a new schema to SQLiteConnection.GetSchema() called Triggers.  - Used to retrieve the trigger(s) associated with a database and/or table/view.
    • -
  • Extensive updates to table/view editing capabilities inside Visual Studio's - Server Explorer.  The program now parses and lets you edit CHECK constraints and - triggers on a table, as well as define triggers on views.  Experimental - still, so e-mail me if you have issues.
    • -
  • Minor bugfix to the ViewColumns schema to return the proper base column name - for a view that aliases a column.
    • -
  • Fixed the insert/update/delete DML support in the Linq module.
    • -
  • Changed the behavior of SQLiteCommand to allow a transaction to be set even if - the command hasn't been associated with a connection yet.
    • -
-

1.0.52.0 - July 16, 2008

-
    -
  • Code merge with SQLite 3.6.0
    • -
  • Added a lot of previously-missing exports to the DEF file for the - native library.
    • -
  • Fixed SQLiteDataReader to check for an invalid connection before operating on - an open cursor.
    • -
  • Implemented the Cancel() function of SQLiteCommand to cancel an active reader.
    • -
  • Added beta table and view designers to the Visual Studio Server Explorer.  You can now - edit/create tables and views, manage indexes and foreign keys from Visual Studio.  - This feature is still undergoing testing so use at your own risk!
    • -
  • Fixed the Server Explorer so VS2005 users can once again right-click tables - and views and open the table data.
    • -
  • Added some new interop code to assist in returning more metadata not normally - available through the SQLite API.  Specifically, index column sort modes - and collating sequences.  Also added code to detect (but not parse) CHECK - constraints, so the table designer can pop up a warning when editing a table - with these constraints.  Since I can't currently parse them.
    • -
  • Lots of LINQ SQL generation improvements and fixes.
    • -
  • Made some progress cleaning up and fixing up the schema definitions and - manifests for EdmGen.
    • -
  • Added a built-in SQLiteFunction called last_rows_affected() which can be - called from SQL to get the number of rows affected by the last update/insert - operation on the connection.  This is roughly equivalent to Sql Server's - @@ROWCOUNT variable.
    • -
-

1.0.51.0 - July 1, 2008

-
    -
  • VS2008 SP1 Beta1 LINQ Support
    • -
  • Added experimental Entity Framework support in a new library, - System.Data.SQLite.Linq.  Some things work, some don't.  I haven't - finished rigging everything up yet.  The core library remains stable.  - All LINQ-specific code is completely separate from the core.
    • -
  • Added some columns to several existing schemas to support some of the - EDM framework stuff.
    • -
  • Minor tweaks to the factory to better support dynamic loading of the Linq - extension library for SQLite.
    • -
  • SQLite's busy handler was interfering with the provider's busy handling - mechanism, so its been disabled.
    • -
-

1.0.50.0 - June 27, 2008

-
    -
  • Fixed some lingering dispose issues and race conditions when some objects were finalized.
    • -
  • Fixed the SQLiteConvert.Split() routine to be a little smarter when splitting - strings, which solves the quoted data source filename problem.
    • -
  • Enhanced the mergebin utility to work around the strong name validation bug on - the Compact Framework.  The old workaround kludged the DLL and caused WM6.1 - to fail to load it.  This new solution is permanent and no longer kludges - the DLL.
    • -
-

1.0.49.0 - May 28, 2008

-
    -
  • Code merge with SQLite 3.5.9
    • -
  • Fixed schema problems when querying the TEMP catalog.
    • -
  • Changed BLOB datatype schema to return IsLong = False instead of True.  This - was preventing DbCommandBuilder from using GUID's and BLOB's as primary keys.
    • -
  • Fix rollover issue with SQLite3.Reset() using TickCount.
    • -
  • Fixed SQLiteDataReader to dispose of its command (if called for) before - closing the connection (when flagged to do so) instead of the other way around.
    • -
  • Fixed a DbNull error when retrieving items not backed by a table schema.
    • -
  • Fixed foreign key constraint parsing bug.
    • -
  • Added FailIfMissing property to the SQLiteConnectionStringBuilder.
    • -
  • Converted the source projects to Visual Studio 2008.
    • -
-

1.0.48.0 - December 28, 2007

-
    -
  • Code merge with SQLite 3.5.4
    • -
  • Calling SQLiteDataReader.GetFieldType() on a column with no schema information - and whos first row is initially NULL now returns type Object instead of type DbNull.
    • -
  • Added support for a new DateTime type, JulianDay.  SQLite uses Julian dates - internally.
    • -
  • Added a new connection string parameter "Default Timeout" and a corresponding - method on the SQLiteConnection object to change the default command timeout.  - This is especially useful for changing the timeout on transactions, which use SQLiteCommand - objects internally and have no ADO.NET-friendly way to adjust the command timeout - on those commands.
    • -
  • FTS1 and FTS2 modules were removed from the codebase.  Please upgrade all - full-text indexes to use the FTS3 module. 
    • -
-

1.0.47.2 - December 10, 2007

-
    -
  • Fixed yet one more bug when closing a database with unfinalized command objects
    • -
  • Fixed the DataReader's GetFieldType function when dealing with untyped SQLite affinities
    • -
-

1.0.47.1 - December 5, 2007

-
    -
  • Fixed a leftover bug from the codemerge with SQLite 3.5.3 that failed to close a database.
    • -
  • Fixed the broken Compact Framework distribution binary.
    • -
  • SQLite 3.5.x changed some internal infrastructure pieces in the encryption interface - which I didn't catch initially.  Fixed. 
    • -
-

1.0.47.0 - December 4, 2007

-
    -
  • Code merge with SQLite 3.5.3
    • -
  • Added installer support for Visual Studio 2008.  Code is still using the - VS2005 SDK so one or two bells and whistles are missing, but nothing significant.
    • -
  • This is the last version that the FTS1 and FTS2 extensions will appear.  - Everyone should rebuild their fulltext indexes using the new FTS3 module.  - FTS1 and FTS2 suffer from a design flaw that could cause database corruption with - certain vacuum operations.
    • -
  • Fixed pooled connections so they rollback any outstanding transactions before - going to the pool. 
    • -
  • Fixed the unintended breaking of the TYPES keyword, and mis-typing of untyped - or indeterminate column types.
    • -
  • Assert a FileIOPermission() requirement in the static SQLiteFunction constructor. -
    • -
  • The CE-only SQLiteFunction.RegisterFunction() is now available on the desktop - platform for dynamic registration of functions.  You must still close and re-open - a connection in order for the new function to be seen by a connection.
    • -
  • Fixed the "database is locked" errors by implementing behavioral changes in the - interop.c file for SQLite.  Closing a database force-finalizes any prepared - statements on the database to ensure the connection is fully closed.  This - was rather tricky because the GC thread could still be finalizing statements itself. -  
    • -
  • Modifed the mergebin utility to help circumvent a long-standing strong name verification - bug in the Compact Framework.
    • -
-

1.0.46.0 - September 30, 2007

-
    -
  • Fixed faulty logic in type discovery code when using SQLiteDataReader.GetValue().
    • -
  • Fixed Connection.Open() bug when dealing with :memory: databases.
    • -
  • Fixed SQLiteCommand.ExecuteScalar() to return a properly-typed value.
    • -
  • Added support for SQLiteParameter.ResetDbType().
    • -
  • Added test cases for rigid and flexible type testing.
    • -
-

1.0.45.0 - September 25, 2007

-
    -
  • Breaking change in GetSchema("Indexes") -- MetaDataCollections - restrictions and identifier parts counts were wrong for this schema and I was using - the wrong final parameter as the final restriction.  Meaning, if you use the - Indexes schema and are querying for a specific index the array should now be {catalog, - null, table, index } instead of {catalog, null, table, null, index}
    • -
  • Code merge with SQLite 3.4.2
    • -
  • Fixed some errors in the encryption module, most notably when a non-default page - size is specified in the connection string.
    • -
  • Fixed SQLiteDataReader to better handle type-less usage scenarios, which also - fixes problems with null values and datetimes.
    • -
  • Fixed the leftover temp files problem on WinCE
    • -
  • Added connection pooling.  The default is disabled for now, but may change - in the future.  Set "Pooling=True" in the connection string to enable it.
    • -
  • Sped up SQLiteConnection.Open() considerably.
    • -
  • Added some more robust cleanup code regarding SQLiteFunctions.
    • -
  • Minor additions to the code to allow for future LINQ integration into the main - codebase.
    • -
  • Fixed a long-standing bug in the Open() command of SQLiteConnection which failed - to honor the documented default behavior of the SQLite.NET provider to open the - database in "Synchronous=Normal" mode.  The default was "Full".
    • -
  • If Open() fails, it no longer sets the connection state to Broken.  It instead - reverts back to Closed, and cleans up after itself.
    • -
  • Added several new parameters to the ConnectionString for setting max page count, - legacy file format, and another called FailIfMissing to raise an error rather than - create the database file automatically if it does not already exist.
    • -
  • Fixed some designer toolbox references to the wrong version of the SQLite.Designer
    • -
  • Fixed a bug in the mergebin utility with regards to COR20 metadata rowsize computations.  -
    • -
  • Minor documentation corrections   
    • -
-

1.0.44.0 - July 21, 2007

-
    -
  • Code merge with SQLite 3.4.1
    • -
  • Fixed a bug in SQLiteConnection.Open() which threw the wrong kind of error in - the wrong kind of way when a database file could not be opened or created. 
    • -
  • Small enhancements to the TYPES keyword, and added documentation for it in the - help file.
    • -
  • Hopefully fixed the occasional SQLITE_BUSY errors that cropped up when starting - a transaction.  Usually occurred in high-contention scenarios, and the underlying - SQLite engine bypasses the busy handler in this scenario to return immediately.
    • -
-

1.0.43.0 - June 21, 2007

-
    -
  • Code merge with SQLite 3.4.0
    • -
  • Fixed a reuse bug in the SQLiteDataAdapter in conjunction with the SQLiteCommandBuilder.  - It's been there unnoticed for more than a year, so it looks like most folks never - encountered it.
    • -
  • Fixed an event handler bug in SQLiteCommandBuilder in which it could fail to unlatch - from the DataAdapter when reused.  Relates to the previous bugfix.
    • -
  • Fixed a double-dispose bug in SQLiteStatement that triggered a SQLiteException. 
    • -
-

1.0.42.0 - June 1, 2007

-
    -
  • Code merge with SQLite 3.3.17
    • -
  • Changed the SQLiteFunction static constructor so it only enumerates loaded modules - that have referenced the SQLite assembly, which hopefully should cut down dramatically - the time it takes for that function to execute. 
    • -
  • Added the FTS2 full-text search extension to the project.  Look for FTS1 - to disappear within the next couple of revisions. 
    • -
  • Fixed a bug introduced with the finalizers that triggered an error when statements - ended with a semi-colon or had other non-parsable comments at the end of a statement 
    • -
  • Fixed an intermittent multi-threaded race condition between the garbage collector - thread and the main application thread which lead to an occasional SQLITE_MISUSE - error.
    • -
  • Fixed another issue relating to SQLite's inherent typelessness when dealing with - aggregate functions which could return Int64 or Double or even String for a given - row depending on what was aggregated.
    • -
  • Remembered to recompile the DDEX portion of the engine this time, so Compact Framework - users can once again use the design-time functionality
    • -
-

1.0.41.0 - April 23, 2007

-
    -
  • Code merge with SQLite 3.3.16
    • -
  • Second go at implementing proper finalizers to cleanup after folks who've forgotten to Dispose() of the SQLite objects
    • -
  • Enhanced GetSchema(IndexColumns) to provide numeric scale and precision values
    • -
  • Fixed the column ordinals in GetSchema(IndexColumns) to report the ordinal of the column in the index, not the table
    • -
  • Fixed a bug whereby parameters named with an empty string (such as String.Empty) were treated like a named parameter instead of an unnamed parameter
    • -
-

1.0.40.0 - January 31, 2007

-
    -
  • Code merge with SQLite 3.3.12
    • -
  • Lots of new code to handle misuse of the library.  Implemented finalizers - where it made sense, fixed numerous garbage collector issues when objects are not - disposed properly,  fixed some object lifetime issues, etc.
    • -
  • A failed Commit() on a transaction no longer leaves the transaction in an unusable - state.
    • -
-

1.0.39.1 - January 11, 2007

-
    -
  • Fixed a really dumb mistake that for some reason didn't trigger any errors in - the testcases, whereby commands when associated with a connection were not adding - or removing themselves from an internal list of commands for that connection -- - causing a "database is locked" error when trying to close the connection.
    • -
-

1.0.39.0 - January 10, 2007

-
    -
  • Code merge with SQLite 3.3.10
    • -
  • Fixed a multi-threaded race condition bug in the garbage collector when commands - and/or connections are not properly disposed by the user.
    • -
  • Switched the encryption's internal deallocation code to use sqlite's built-in - aux functions instead of modifying the pager.c source to free the crypt block.  - This eliminates the last of the code changes the provider makes to the original - sqlite engine sources.  Props to Ralf Junker for pointing that out.
    • -
-

1.0.38.0 - November 22, 2006

-
    -
  • Fixed a bug when using CommandBehavior.KeyInfo whereby integer primary key columns may be duplicated in the results.
    • -
  • Enhanced the CommandBuilder so that update/delete statements are optimized when the affected table contains unique constraints and - a primary key is present.
    • -
  • Fixed a bug in the DataReader when used in conjunction with CommandBehavior.CloseConnection.
-

1.0.37.0 - November 19, 2006

-
    -
  • Added support for CommandBehavior.KeyInfo.  - When specified in a query, additional column(s) will be returned describing the - key(s) defined for the table(s) selected in the query.  This is optimized when - INTEGER PRIMARY KEY is set for the given tables, but does additional work for other - kinds of primary keys.
    • -
  • Removed the default values from SQLiteDataReader.GetTableSchema(), to better follow - Sql Server's pattern and suppress schema errors when loading the records into a - dataset/datatable.
    • -
  • Allow integers to implicitly convert to double/decimal/single.
-

1.0.36.1 - October 25, 2006

-
    -
  • Added support for LONGVARCHAR, SMALLDATE and SMALLDATETIME. These were actually added in 1.0.36.0 but were undocumented.
    • -
  • Fixed the embedded helpfile which was accidentally built from old sources.
    • -
  • Fixed an unfortunate re-entry of a bug in the .36 codebase that caused the provider to "forget" about commands on a connection under certain circumstances.
    • -
-

1.0.36.0 - October 23, 2006

-
    -
  • Code merge with SQLite 3.3.8, including support for full-text search via the FTS1 - extension. 
  • Fixed a bug retrieving data types when UseUtf16Encoding is true. Side-effect of further merging the common code between the two base classes.
    • -
  • Fixed a bug with System.Transactions whereby a connection closed/disposed within - a transaction scope is rolled back and cannot be committed.
    • -
  • Added more error checking and reporting to transactions to help user's isolate - the source of transaction failures.
    • -
  • Implemented a workaround for a Compact Framework issue regarding strong-named - assemblies containing a PE section with a raw size less than the virtual size. 
    • -
-

1.0.35.1 - September 12, 2006

-
    -
  • Fixed the TYPES keyword to work when UseUTF16Encoding is true.
    • -
  • Fix another bug revealed in 1.0.35.0 regarding infinite loops when the 2nd or subsequent statements of a semi-colon separated command cannot be parsed.
    • -
  • Updated the help documentation. 
    • -
-

1.0.35.0 - September 10, 2006

-
    -
  • Fixed an infinite loop bug in SQLiteCommand caused when multiple semi-colon separated - statements in a single command are executed via datareader and one of the statements - contains a syntax error preventing it from being prepared. 
  • Added the TYPES preparser keyword to be placed before a SELECT statement to - aid the wrapper in converting expressions in a subsequent select clause into more - robust types.  Documentation yet to be integrated, but available on the forums.
    • -
  • Added a new connectionstring parameter "BinaryGUID=true/false" (default is "true").  - When true, guid types are stored in the database as binary blobs to save space.  - Binary has been the default format since 1.0.32.0 but this parameter eases backward - compatibility.
    • -
-

1.0.34.0 - September 4, 2006

-
    -
  • Fixed a bug in SQLiteParameterCollection.RemoveAt(namedparam)
    • -
  • Fixed a bug in SQLiteDataReader introduced in 1.0.30 that broke DateTimes using the Ticks option in the connection string.
    • -
  • Fixed a bug in the recent changes to guid behavior wherein using a datareader's - indexer to fetch a guid from a column containing both binary and text guids would - sometimes return a byte array instead of a guid.
    • -
  • Enacted a workaround involving typed datasets in Compact Framework projects in - which it took an excessive amount of time to open a form and generated a lot of - temporary files in the user's Local Settings\Application Data\Microsoft\VisualStudio\8.0\Assembly - References folder.
    • -
-

1.0.33.0 - August 21, 2006

-
    -
  • Code merge with SQLite 3.3.7
    • -
  • Fixed a bug in SQLiteConnection that caused it to "forget" about commands bound - to it and occasionally throw an error when a database is closed and opened repeatedly.  -
    • -
-

1.0.32.0 - August 6, 2006

-
    -
  • Added AllowPartiallyTrustedCallers attribute to the assembly
  • Added the missing "nchar" type
    • -
  • Added support for binary Guid's.  Guids are now stored as binary by default - when using parameterized queries.  Text guids are still fully supported.
    • -
  • Fixed a TransactionScope() error that caused the transaction not to be completed.
    • -
  • Enhanced parameter names so that if they are added to the Parameters collection - without their prefix character (@ : or $) they are still properly mapped. 
    • -
-

1.0.31.0 - July 16, 2006

-
    -
  • Re-applied the view parsing bugfix in 1.0.29.0 that was accidentally reverted - out of the 30 build.
  • Fixed SQLiteCommand.ExecuteScalar() to return null instead of DbNull.Value - when no rows were returned.
    • -
  • Design-time installer now installs the package-based designer on full Visual Studio - versions.  Express editions continue to use the packageless designer.
    • -
  • In Visual Studio (not Express), you can now right-click a SQLite connection in - the Server Explorer and vacuum the database and change the encryption password.
    • -
-

1.0.30.1 - July 2, 2006

-
    -
  • Code merge with SQLite 3.3.6
    • -
  • Added support for the |DataDirectory| keyword in the Data Source filename string.  -
    • -
  • Added hook notification support to SQLiteConnection.  Specifically, there - are three new events on the SQLiteConnection object which are raised when an update/insert/delete - occurs and when transactions are committed and rolled back.
  • Changed SQLiteTransaction to default to BEGIN IMMEDIATE instead of just BEGIN, - which solves a multithreaded race condition. 
    • -
  • Changed SQLiteDataReader to better support SQLite's typelessness.  The data - reader no longer caches column affinity, but re-evaluates it for each column/row.
    • -
  • Fixed a bug in Prepare() which caused an intermittant fault due to the code accessing - the memory of an unpinned variable. 
    • -
  • Fixed a multithreaded lock-retry bug in in SQLiteConnection.Open() and in - SQLiteTransaction, which failed to use a command timeout before giving up.
    • -
-

1.0.29.0 - May 16, 2006

-
    -
  • Fixed a bug in the Views schema information which caused multi-line view definition statements not to be parsed
    • -
  • Fixed a parsing bug in SQLiteDataReader.GetSchemaTable() to account for numeric(x,y) datatypes with specified precision and scale
    • -
  • Fixed a bug in SQLiteConnection.Open() which tried to automatically enlist in an ambient transaction but had not yet set the state of the database to Opened, thereby causing a transaction fault
    • -
  • Changed SQLiteException to inherit from DbException on the full framework
    • -
-

1.0.28.0 - April 14, 2006

-
    -
  • Code merge with SQLite 3.3.5
    • -
  • You can now specify a relative path in the Compact Framework's "Data Source" by - prefixing the file with ".\".  i.e. "Data Source=.\\mydb.db3"
    • -
  • Several more changes and enhancements to schemas for better compatibility.
    • -
  • Fixed several bugs with the 64-bit builds of the provider.  The x64 binary - is now optimized.
    • -
  • Design-time installer now tries to install the 64-bit builds into the GAC along - with the 32-bit build.
    • -
  • Fixed a bug in the SQLiteDataReader.GetSchemaTable() function when used with tables - containing apostrophes.
    • -
  • Fixed an XSD-related bug whereby the XSD utility was unable to locate the provider - and could not generate typed datasets.
    • -
  • Added NTEXT and STRING datatypes to the list of recognized keywords (used for - schema retrieval).
    • -
  • Due to the XSD bug and other potential problems related to external build utilities, - changes to the installation of the designer have had to be made.  The installer - used to write the DbProviderFactories XML into the devenv.exe.config file and its - express cousins, but now has to write instead to the machine.config.
    • -
  • Installer writes to both the 32-bit machine.config and the 64-bit machine.config - if it exists. 
    • -
-

1.0.27.1 - February 28, 2006

-
    -
  • Fixed a bug when doing data binding in Compact Framework projects that prevented - you from assigning a typed dataset to a bindingsource.  It turns out, the CF - version of the SQLite provider needs to be flagged as retargetable so it'll work - in the design-time desktop environment.  No changes were made to the desktop - build, but the revision was bumped on all libraries anyway in order to keep them - sync'd. 
-

1.0.27.0 - February 27, 2006

-
    -
  • Many optimizations and a few more minor adjustments to schemas and schema retrieval - performance.
    • -
  • Lots of design-time attributes added to the code.  The DbDataAdapter, DbCommand, - and DbConnection objects now have greatly enhanced design-time capabilities when - added to the toolbox and dropped on a form.
    • -
  • Lots of Server Explorer enhancements.
    • -
  • Binaries are now distributed in a setup program for easier administration and - configuration of the provider.
    • -
-

1.0.26.2 - February 15, 2006

-
    -
  • Yet another bugfix to index schemas, which was incorrectly marking most indexes - as primary key indexes.
  • Fixed GetSchema() to accept a null string array.
  • Fixed a misspelled export in the core C library that prevented databases opened - with UTF16Encoding from getting schema information and would likely cause an error - if attempted.
-

1.0.26.1 - February 14, 2006

-
    -
  • Fixed even more minor schema bugs having to do with indexes.
  • Added two missing pieces in the SQLite designer which were preventing it from - being used from within VS Express editions. 
  • Several bugfixes to the design-time installer program, including supporting - 64-bit environments.
-

1.0.26.0 - February 11, 2006

-
    -
  • Code merge with SQLite 3.3.4
  • Fixed an encryption bug when changing the password of databases over 1gb in - size. 
  • Fixed various designer issues related to construction of named parameters.
    • -
  • Retooled the GetSchema() method of SQLiteDataReader to use the new 3.3.4 API functions, - and made several enhancements and fixes to schemas. 
    • -
  • Implemented the SourceColumnNullMapping property of SQLiteParameter to fix - a DbCommandBuilder code generation bug. 
  • Removed the runtime dependency on MSVCR80.DLL.  File size is somewhat - larger for the varying desktop versions.
  • Created an install program to manage installation and uninstallation of the - SQLite design-time support.
    • -
  • Designer support now works for all Visual Studio editions, including all Express - Editions.
    • -
  • Design-time installer will now remove (if present) the machine.config SQLite entries - in favor of installing the xml code into the devenv.exe.config file (or any of the - variations for express editions).  The officially-accepted behavior of using - DbProviderFactories is to add the code to your app.config file, and the machine.config - file should not be touched.
    • -
-

1.0.25.0 - January 31, 2006

-
    -
  • Code merge with SQLite 3.3.3
  • Added automatic distributed transaction enlistment and implemented the DbConnection.EnlistTransaction - method for manual enlistment.
    • -
  • Nested transactions are now supported.
    • -
  • Rearranged the timing of SetPassword(), which now must be called before the database - is opened instead of afterwards.  Optionally, the password can be supplied - in the ConnectionString.
    • -
  • Fixed a bug in SQLiteFunction that caused a failure when an empty resultset was - returned and a custom user aggregate function was used in the query.
    • -
  • The designer has had another round of cleanup applied, in preparation for moving - to a VS package.
    • -
  • Added SQLiteMetaDataCollectionNames class.
    • -
-

1.0.24.6 beta - January 23, 2006

-
    -
  • This beta is built from sqlite.org's 3.3.2 beta.
  • Eliminated the static linking of mscoree from all binaries.  Native projects - can now use the library without any dependencies on the .NET framework, while managed - projects continue to be able to use the library normally.
-

1.0.24.5 beta - January 20, 2006

-
    -
  • This beta is built from sqlite.org's 3.3.1 alpha and contains development-in-progress code.  Therefore no guarantees - can be made regarding its suitability for production use.
    • -
  • You no longer need to distribute 2 files on the CompactFramework.  - You can delete SQLite.Interop.DLL entirely.  I wrote a custom tool - called "mergebin" (available in the source zip file) which combines the two libraries - and gets around a glaring defect in the VS2005 linker for ARM processors which doesn't - allow you to link netmodules.
    • -
  • x64 and ia64 builds now use the same strong name as the x86 build.  - This means breaking backward compatibility, but it was necessary in order to allow - you to drop any of those 3 builds onto a PC and have your .NET program run properly.  - Prior to this, you'd get an error if you built your program using the x86 build, - and then installed the x64 version on a target machine and tried to run your program - against it.
    • -
  • The entire source project has been gone over top to bottom.  A debug build - no longer combines the binaries into a single module, which was preventing proper - debugging.

1.0.24.4 beta - January 16, 2006

-
    -
  • This beta is built from sqlite.org's 3.3.1 alpha and contains development-in-progress code.  Therefore no guarantees - can be made regarding its suitability for production use.
    • -
  • Fixed a bug in the UTF-16 handling code for preparing statements due to a behavioral - change in SQLite 3.3.0.
    • -
  • Added pager.c code necessary to cleanup after an encrypted file is closed.
    • -
  • Fixed an encryption bug that caused a fault when an encrypted file was rolled - back.
    • -
  • Modified the testcase code to take advantage of optimizations regarding the use - of a DbCommandBuilder.  DataAdapter insert speed increased dramatically as - a result.
    • -
-

1.0.24.3 beta - January 10, 2006

-
    -
  • This beta is built from sqlite.org's 3.3.0 alpha and contains development-in-progress code.  Therefore no guarantees - can be made regarding its suitability for production use.
  • Added support for database encryption at the pager level.  Databases - are encrypted using a 128-bit RC4 stream algorithm.  To open an existing encrypted - database, you may now specify a "Password={password}" text in the ConnectionString, - or you may call the SQLiteConnection.SetPassword() function to set the password - on an open connection.  To encrypt existing non-encrypted databases or to change - the password on an encrypted database, you must use the SQLiteConnection.ChangePassword() - function.  If you use SetPassword() instead of specifying a password in the - connection string, or call ChangePassword() you may use a binary byte array or a - text string as the password.
    • -
  • Rewrote the locking implementation for the Compact Framework.  It is now - more robust and incorporates into the SQLite codebase more efficiently than the - previous CE adaptation.
    • -
  • Moved some of the embedded schema XML data into a resource file to ease code readability.
    • -
  • Automated the fixup of the original sqlite codebase's source prior to compiling, - to ease merging with sqlite.org's source.
    • -
  • Fixed a memory leak in SQLiteCommand due to it not removing an internal reference - to itself in SQLiteConnection. 
    • -
-

1.0.24.2 - December 30, 2005

-
    -
  • Fixed the SQLiteDataReader.HasRows property to return the proper value.
    • -
  • Implemented the inadvertently neglected RecordsAffected property on SQLiteDataReader. -
    • -
  • SQLiteFunction static constructor was changed to pre-filter classes with only the - SQLiteFunctionAttribute.  The code was throwing an exception when certain - assemblies were referenced in a project.
    • -
  • Fixed the SQLiteDataAdapter OnRowUpdated event, which was using the wrong variable - to find the attached event handler and subsequently not raising the event.
    • -
  • Small optimizations and fixes to SQLiteDataReader.NextResult(). 
    • -
-

1.0.24.1 - December 19, 2005

-
    -
  • Update core SQLite engine to 3.2.8 
-

1.0.24 - December 9, 2005

-
    -
  • Fixed the Catalogs schema bug that caused attached databases not to be re-attached to a cloned connection -
    • -
  • Enhanced transactions to allow for a deferred or immediate writelock.  SQLiteConnection.BeginTransaction() - now has an additional overload to support it 
  • Commands are now prepared as they are executed instead of beforehand.  This - fixes a bug whereby a multi-statement command that alters the database and subsequently - references the altered data would fail during Prepare().
  • Tightened up the SQLiteDataReader to prevent reading columns before calling - the first Read() and to prevent reading columns after the last Read().
    • -
  • A more descriptive error is thrown if there aren't enough parameters in the command - to satisfy the parameters required by the statement(s). 
    • -
-

1.0.23 - November 21, 2005

-
    -
  • Named parameters may now begin with @ to ease portability of - the provider. SQLite's named parameters are ordinarily prefixed with a : - or $.  The designer will still use the $ - prefix however, since its more compatible with the default SQLite engine.
  • Added several alternate ISO8601 date/time formats to SQLiteConvert.cs to increase - compatibility.
    • -
  • Relaxed coersion restrictions to work better with SQLite's inherent typelessness. 
    • -
-

1.0.22 - November 11, 2005

-
    -
  • Fixed some globalization issues which resulted in incorrect case-insensitive comparisons
    • -
  • Fixed a bug in the routine that finds all user-defined functions in a loaded assembly.  - It would throw an exception if any of the types in the assembly could not be loaded.  - The exception is now caught and handled appropriately.
    • -
-

1.0.21 - November 4, 2005

-
    -
  • Fixed a designer bug when creating typed datasets with parameterized queries.
    • -
  • The above fix then exposed another bug in the datareader's ability to query schema - information on parameterized commands, which was also fixed.
    • -
  • Compiled against the RTM version of VS2005.
    • -
  • Rewrote the design-time install script to use the XML DOM objects when writing - to the machine.config and to automatically register the DLL in the GAC.
  • Made changes to the app.config descriptions and help file to improve version-independent - factory support.
-

1.0.20 - October 19, 2005

-
    -
  • - Fixed a shortcut in SQLiteBase.GetValue which was insufficient for - international environments.  The shortcut was removed and the "proper" - procedure put in.
-

1.0.19 - October 5, 2005

-
    -
  • - Code merge with SQLite 3.2.7 -
  • - Fixed bugs in the CE port code (os_wince.c) which were brought to - light by recent changes in the SQLite engine. -
  • - Recompiled and modified to be compatible with the September VS2005 Release - Candidate.
    - Beta 2 users should continue to use 1.0.18.1
-

1.0.18.1 - September 19, 2005

-
    -
  • - Code merge with SQLite 3.2.6
-

1.0.18 - September 1, 2005

-
    -
  • - Added type-specific method calls when using the various SQLite classes that - would've normally returned a a generic Db base class, which aligns the code - better with the Microsoft-supplied data providers.
-

1.0.17 - August 26, 2005

-
    -
  • - Code merge with SQLite 3.2.5 -
  • - Added Itanium and x64 build settings to the project (needs testing) -
  • - Bugfixes and enhancements to several schema types -
  • - Additional design-time support to include index and foreign key - enumerations.  Requires re-registering the designer using - INSTALL.CMD.  The new designer code now allows the VS query designer and - typed datasets to automatically link up foreign keys, use indexes, and - automatically generate relationships from the schema.
  • - Additional static methods on SQLiteConnection to create a database file, - encrypt a file using the Encrypted File System (EFS) on NTFS (requires NT 2K or - above) and NTFS file compression
    • -
-

1.0.16 - August 24, 2005

-
    -
  • - Code merge with SQLite 3.2.4 with the large delete bugfix in CVS (which will - become 3.2.5 soon) -
  • - Added new GetSchema() types: IndexColumns, ViewColumns, ForeignKeys
    • -
-

1.0.15 - August 22, 2005
-

-
    -
  • - Code merge with SQLite 3.2.3 -
  • - Minor updates for better design-time experience. More design-time code to - follow in subsequent releases.
    • -
-

1.0.14 - August 16, 2005
-

-
    -
  • - Fixed a bug in the SQLiteDataAdapter due to insufficient implementation of the - class.  The RowUpdating and RowUpdated events are now properly - implemented, but unfortunately inserting and updating data in a DataTable or - DataSet is now much slower.  This is the proper design however, so the - changes are here to stay. -
  • - Lots of schema changes to support Visual Studio's Data Designer architecture.
  • Added - Designer support for the provider.  It's not 100%, but you can design - queries, add typed datasets and perform quite a number of tasks all within - Visual Studio now.
-

1.0.13 - August 8, 2005
-

-
-
    -
  • - Fixed a named parameter bug in the base SQLite_UTF16 class, which of course - only showed up when a database connection was opened using the - UseUTF16Encoding=True parameter. -
  • - Fixed a performance issue in SQLite_UTF16 involving string marshaling.
-
-

1.0.12 - August 5, 2005
-

-
-
    -
  • - Full support for the Compact Framework.  Each build (Debug/Release) now - has a platform, either Win32 or Compact Framework.  The correct - projects are built accordingly.  See the Distributing - SQLite - section for information on what files need to be distributed for each - platform.  -
  • - Modified SQLite3.Reset() and Step() functions to transparently handle timeouts - while waiting on the database to become available (typically when a writer is - waiting on a reader to finish, or a reader is waiting on a writer to finish). -
  • - Lots of code cleanup as suggested by the Code Analyzer (FxCop). -
  • - Lots of updates to the helpfile (as you can see). -
  • - Statements were already prepared lazily in a SQLiteCommand, but now - its even more lazy.  Statements are now only prepared if the statements - haven't been previously prepared and a Prepare() function is called (and the - command is associated with a connection) or just prior to the command being - executed. 
-
-

1.0.11 - August 1, 2005
-

-
    -
  • - For everything except the Compact Framework, System.Data.SQLite.DLL is - now the only DLL required to use this provider!  The - assembly is now a multi-module assembly, containing both the native SQLite3 - codebase and the C# classes built on top of it.  The Compact Framework - version (when completed) will not be able to support this feature, so backwards - compatibility with the Compact Framework has been preserved for the future. -
  • - Fixed a bug in SQLiteCommand.ExecuteScalar() that caused it to stop executing - commands once it obtained the first column of the first row-returning - resultset.  Any remaining statements after the row-returning statement was - ignored. -
    • -
-

1.0.10 - June 10, 2005
-

-
    -
  • - Fixed a bug in the SQLite3.cs Prepare() function that created a statement even - when the SQLite engine returned a NULL pointer. Typically this occurs when - multiple statements are processed and there are trailing comments at the end of - the statement. -
  • - Fixed a bug in SQLiteStatement.cs that retrieved parameter names for a - parameterized query.  SQLite's parameters are 1-based, and the function - was starting at 0.  This was fine when all parameters were unnamed, but - for named parameters it caused the parameters to be out of whack. -
    • -
-

1.0.09a - May 25, 2005
-

-
    -
  • - Fixed a broken helpfile and corrected some obsolete help remarks in - SQLiteFunction.cs -
  • - Added a version resource to the SQLite.Interop.DLL. 
-

1.0.09 - May 24, 2005
-

-
    -
  • - Code merge with the latest 3.21 version of SQLite. -
  • - Removed obsolete methods and properties for Whidbey Beta 2
-

1.0.08 Refresh - Mar 24, 2005
- -

-
    -
  • - Code merge with the latest 3.20 version of SQLite. -
  • - Recompiled the help file to fix a build error in it. -
    • -
-

1.0.08 - Mar 11, 2005
- -

-
    -
  • - Added additional #if statements to support the old beta 1 edition of VS2005. -
  • - Code merged the SQLite 3.14 source. -
    • -
-

1.0.07 - Mar 5, 2005
-

-
    -
  • - Made more optimizations to frequently-called functions, resulting in - significant performance gains in all tests. -
  • - Recompiled the binaries using the latest VS2005 February CTP, resulting in yet - more significant speed gains.  The 100k insert test used to take 3.5 - seconds and the insertwithidentity took almost 8 seconds.  With the above - two changes, those tests are now executing in 1.9 and 4.9 seconds respectively.
-

1.0.06 - Mar 1, 2005
- -

-
    -
  • - Speed-ups to SQLiteDataReader.  It was interop'ing unnecessarily every - time it tried to fetch a field due to a logic error. -
  • - Changed/Added some code to SQLiteConvert's internal DbType, Type and - TypeAffinity functions. -
  • - Fixed the SQLiteDataReader to obey the flags set in the optional - CommandBehavior flag from SQLiteCommand.ExecuteReader(). -
  • - Changed the default page size to 1024 to reflect the defaults of SQLite.  - Ignores the "Page Size" connection string option for memory databases, as tests - revealed that changing it resulted in memory corruption errors. -
  • - Performance enhancements to the SQLiteCommand and SQLiteStatement classes which - reduced the 100,000 row insert execution time as well as the various Function - execution times significantly. -
    • -
-

1.0.05 - Feb 25, 2005 -

-
    -
  • - Fixed the SQLite3 C# class step/reset functions to accomodate schema changes - that invalidate a prepared statement.  Statements are recompiled - transparently. -
  • - Moved all native DLL declarations to an UnsafeNativeMethods class. -
  • - Split several classes into their own modules for readability. -
  • - Renamed many internal variables, reviewed access to variables marked as - internal and altered their protection levels accordingly. -
  • - Due to the presence of the altered sqlite3 codebase and so many added interop - functions, I decided to rename the sqlite3 C project and the DLL to - SQLite.Interop.DLL.  This is the same core sqlite3 codebase but designed - specifically for this ADO.NET provider.  This eliminates any possibility - of someone dropping another build of sqlite3.dll into the system and rendering - the provider inoperable.  In the future if the folks at sqlite.org finally - introduce a method of retrieving column usage for an arbitrary prepared - statement, I'll retool this library to be a lightweight function call wrapper - around the core binary distribution. -
  • - Added [SuppressUnmanagedCodeSecurity] attribute to the UnsafeNativeMethods - class which brings VS2005 November CTP execution speeds inline with the - December CTP. -
  • - Added a bin - directory to the project root where pre-compiled binaries can be found. -
  • - Added a doc - directory where preliminary documentation on the class library can be found. -
  • - Documented a lot more of the classes internally. -
    • -
-

1.0.04 - Feb 24, 2005 -

-
    -
  • - Removed the SQLiteContext class and revamped the way UserFunctions work to - simplify the imlementation. -
  • - Fixed a counting bug in the TestCases class, specifically in the function tests - where I wasn't resetting the counter and it was consequently reporting - intrinsic and raw select calls as being much much faster than they actually - were.  The numbers are now much closer to what I expected for performance, - with .NET user-functions still being the slowest, but only by a small margin. -
  • - Small performance tweaks to SQLiteDataReader. -
  • - Added PageSize to the SQLiteConnectionStringBuilder and subsequently to the - SQLiteConnection -
  • - Added a PRAGMA encoding=XXX execution statement to the SQLiteConnection after - opening a connection. -
    • -
-

1.0.03 - Feb 23, 2005 -

-
    -
  • - Fixed up SQLiteCommandBuilder to correct implementation errors, which resulted - in an enormous performance boost in the InsertMany test.   10,000 row - insert that executed in 1500ms now executes in 500ms. -
  • - Fixed several errors in the SQLite3_UTF16 class.  ToString() was working - incorrectly and the Open() method failed to register user defined functions and - collations. -
  • - Fixed a bug in SQLiteCommand.ClearCommands() whereby only the first statement - was being properly cleaned up. -
  • - Fixed a bug in SQLiteDataReader whereby calling NextResult() would not properly - reset the previously-executed command in the sequence. -
  • - Added an InsertManyWithIdentityFetch test, which appends a select clause to - populate the ID of the last inserted row into the InsertCommand, demonstrating - ADO.NET's ability to auto-fetch identity columns on insert. -
    • -
-

1.0.02 - Feb 21, 2005

-
    -
  • - Tweaks to the xxx_interop functions that return char *'s, so they also return - the length.  Saves an interop call to get the UTF-8 string length during - conversion to a .NET string. -
  • - Reworked the whole interop.c thing into interop.h and reduced the code required - to merge the main sqlite3 codebase. -
  • - Added support for user-defined collations. -
    • -
- - + + + + + + + ADO.NET 4.0 SQLite Data Provider
+ Version 1.0.66.1 April 18, 2010
+ Using SQLite 3.7.0.1
+ Written by Robert Simpson (robert@blackcastlesoft.com)
+ Released to the public domain, use at your own risk!
+ Official provider website:  http://sqlite.phxsoftware.com
+
+ The latest version can be downloaded + here +
+
+ +

+ Features:
+

+
    +
  • + Written from scratch on VS2008 specifically for ADO.NET 2.0, implementing all the + base classes and features recently introduced in the framework, including automatic + transaction enlistment.
  • Supports the Full + and Compact .NET Framework, and native C/C++ development.  100% binary + compatible with the original sqlite3.dll.
    • +
  • Full support for Mono via a "managed only" provider that runs against the + official SQLite 3.6.1 or higher library.
    • +
  • Full Entity Framework support (ADO.NET 3.5 SP1)
    • +
  • + On the Compact Framework, it is faster than Sql Server + Mobile. SQLite's installed size is a fraction of Sql Mobile's. It uses less memory at runtime, runs queries faster, and has a smaller database file size as well. +
  • Encrypted database support.  Encrypted databases are fully encrypted and + support both binary and cleartext password types.
    • +
  • + Visual Studio 2005/2008 Design-Time Support, works with all versions of VS2005/2008, + including + all Express Editions of VS2005.  You can add a SQLite + database to the Servers list, design queries with the Query Designer, + drag-and-drop tables onto a Typed DataSet, etc.
  • + Full SQLite schema editing inside Visual Studio.  + You can create/edit tables, views, triggers, indexes, check constraints and foreign keys.
  • + Single file redistributable (except on Compact Framework).  The core sqlite3 codebase and the ADO.NET wrapper + are combined into one multi-module assembly. +
  • + Binaries included for Itanium, x64, x86 and ARM processors.
  • + DbProviderFactory support. +
  • + Full support for ATTACH'ed databases.  Exposed as Catalogs + in the schema.  When cloning a connection, all attached databases are + automatically re-attached to the new connection. +
  • + DbConnection.GetSchema(...) support includes ReservedWords, MetaDataCollections, DataSourceInformation, + DataTypes, Columns, Tables, Views, ViewColumns, Catalogs, Indexes, + IndexColumns, ForeignKeys and Triggers. +
  • + Enhanced DbDataReader.GetSchemaTable() functionality returns catalog, namespace + and detailed schema information even for complex queries. +
  • + Named and unnamed parameters. +
  • + Full UTF-8 and UTF-16 support, each with optimized pipelines into the native + database core. +
  • + Multiple simultaneous DataReaders (one DataReader per Command however). +
  • + Full support for user-defined scalar and aggregate functions, encapsulated into + an easy-to-use base class in which only a couple of overrides are necessary to + implement new SQL functions. +
  • + Full support for user-defined collating sequences, every bit as simple to + implement as user-defined functions and uses the same base class. +
  • + Full source for the entire engine and wrapper.  No copyrights.  + Public Domain.  100% free for commercial and non-commercial use. 
+ +

+ Design-Time Support

+

+ In Windows Explorer, navigate to the SQLite.NET\bin\Designer + folder and execute the INSTALL.EXE + file.  The program will + automatically detect what version(s) of Visual Studio 2005/2008 are installed and allow + you to selectively install and uninstall the designer for each edition.

+

DbFactory Support (Non-Compact Framework)

+ In order to use the SQLiteFactory and have the SQLite data provider enumerated + in the DbProviderFactories methods, you must add the following segment into your application's app.config file:
+
+ 
<configuration>
+  <system.data>
+    <DbProviderFactories>
+      <remove invariant="System.Data.SQLite"/>
+      <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite"
 type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />
+    </DbProviderFactories>
+  </system.data>
+</configuration>
+
+

See the help documentation for further details on implementing both version-specific (GAC enabled) and version independent DBProviderFactories support. +

+

+ Compiling for the Compact Framework

+

+ Just change the target platform from Win32 to Compact Framework and + recompile.  The Compact Framework has no support for enumerating + attributes in an assembly, therefore all user-defined collating sequences and + functions must be explicitly registered.  See the testce + sample application for an example of how to explicitly register user-defined + collating sequences and functions.

+

+ Distributing The SQLite Engine and ADO.NET Assembly

+

+ On the desktop, only the System.Data.SQLite.DLL file needs to be distributed with your + application(s).  This DLL contains both the managed wrapper and the native + SQLite3 codebase.  For the Compact Framework, you will have to distribute + both the CF version of System.Data.SQLite.DLL, as well as the + SQLite.Interop.XXX.DLL.  This is a breaking change as of 1.0.59.0.  + Recent Windows Mobile frameworks are not supporting the mixed CF assembly I was + building prior to this version.

+

Development Notes Regarding the SQLite 3 Source Code

+

+ The core sqlite engine is compiled directly from the unmodified source code available + at the sqlite.org website.  Several additional pieces are compiled on top of + it to extend its functionality, but the core engine's source is not changed.

+

+

+ Version History

    +
  • Code merge with SQLite 3.7.0.1
    • +
  • Re-enabled VS2005 designer support, broken in previous versions during the 2008 transition
    • +
  • Implemented new forms of Take/Skip in the EF framework courtesy jlsantiago
    • +
  • Added "Foreign Keys" to the connection string parameters
    • +
  • Added the Truncate option to the Journal Modes enumeration
    • +
+

1.0.66.0 - April 18, 2010

+
    +
  • Code merge with SQLite 3.6.23.1
    • +
  • Fixed a bug in the installer that accidentally modified the machine.config on .NET versions prior to 2.0, invaliding the config file.
    • +
  • Fixed INTERSECT and EXCEPT union query generation in EF
    • +
  • Fixed an out of memory error in the trigger designer in cases where a WHEN clause is used in the trigger
    • +
+

1.0.65.0 - July 26, 2009

+
    +
  • Fixed a bug in the encryption module to prevent a double free() when rekeying a database.
    • +
  • Fixed a bug in the encryption module when ATTACHing an encrypted database.
    • +
  • Incorporated the WinCE locking fix from ticket + #3991
    • +
  • Added "bigint" to the dropdown in the table designer, plus other minor table + designer bugfixes.
    • +
+

1.0.64.0 - July 9, 2009

+
    +
  • Fixed the missing resources problem from the 63 release.
    • +
  • Added preliminary support for the Visual Studio 2010 beta.
    • +
  • Fixed a bug in SQLiteCommand that threw a null reference exception when + setting the Transaction object to null.
    • +
  • If SQLiteConnection.EnlistTransaction is called multiple times for the same + transaction scope, just return without throwing an error.
    • +
+

1.0.63.0 - June 29, 2009

+
    +
  • Code merge with SQLite 3.6.16
    • +
  • Check the autocommit mode of the connection to which a transaction is bound + during the disposal of the transaction.  If autocommit is enabled, then the + database has already rolled back the transaction and we don't need to do it + during dispose, and can quietly ignore the step without throwing an error.
    • +
  • Eliminated the mergebin step altogether.  It was developed primarily to + merge the Compact Framework binaries together, but since we're not doing that + anymore, its use is limited.  Its non-standard method of merging a binary + on the desktop framework is redundant as well.  The desktop binary now + hard-links to MSCOREE, but as of Windows XP, this was redundant as well since XP + and beyond automatically attempt to load MSCOREE on startup when a DLL has a + .NET header.
    • +
  • More improvements to the test.exe program for running the tests against Sql + Server for comparison purposes.
    • +
+

1.0.62.0 - June 19, 2009

+
    +
  • Code merge with SQLite 3.6.15
    • +
  • Fixed the decimal reading bug in the SQLiteDataReader
    • +
  • Changed Join()'s to Sleep()'s in the statement retry code to prevent message + pumping
    • +
  • Fixed a bad pointer conversion when retrieving blobs using GetBytes() in + 64-bit land
    • +
  • Several changes to the Test program that comes with the provider.  Tests + can now be individually disabled, and the test program can run against several + provider back-ends
    • +
+

1.0.61.0 - April 28, 2009

+
    +
  • Code merge with SQLite 3.6.13. The new backup features are as yet unimplemented in the provider, but will be forthcoming in a subsequent release
    • +
  • Fixed the default-value lookups in SQLiteConnectionStringBuilder when accessing properties
    • +
  • Lock the SQLiteTransaction object during dispose to avoid potential race condition during cleanup
    • +
  • Fixed SQLiteDataReader.GetDecimal() processing and parsing of decimal values for cases when SQLite returns things like "1.0e-05" instead of "0.0001"
    • +
+

1.0.60.0 - October 3, 2008

+
    +
  • Throw a NotSupported exception in the EF Sql Gen code instead of parsing + illegal SQL during an update/insert/delete where no primary key is defined.
    • +
  • Fixed the Compact Framework interop library.  Since the linker flag + /subsystem had no version specified, it was causing a problem for many CE-based + platforms.
    • +
  • Incorporated SQLite patch for ticket + #3387 and reverted + out the vfs override code I added in build 59 to work around this problem.
    • +
  • Fixed a designer issue when creating a new table from the Server Explorer.  + After initially saving it, if you then continued to edit it and tried to save it + again, it would generate the change SQL using the old temporary table name + rather than the new name.
    • +
+

1.0.59.0 - September 22, 2008

+
    +
  • Code merge with SQLite 3.6.3.  Solves + a couple different EF issues that were either giving inconsistent results or + crashing the engine.
    • +
  • Fixed the parsing of literal binaries in the EF SqlGen code.  SQLite now + passes nearly all the testcases in + Microsoft's EF Query Samples application -- + the exception being the datetimeoffset and time constants tests, and tests + that use the APPLY keyword which are unsupported for now.
    • +
  • Revamped the Compact Framework mixed-mode assembly.  Tired of playing cat + and mouse with the Compact Framework's support for mixed-mode assemblies.  + The CF build now requires that you distribute both the System.Data.SQLite + library and the paired SQLite.Interop.XXX library.   The XXX denotes + the build number of the library.
    • +
  • Implemented a workaround for Vista's overzealous caching by turning off + FILE_FLAG_RANDOM_ACCESS for OS versions above XP.  This is implemented + as a custom (default override) VFS in the interop.c file, so no changes are made + to the SQLite source code.
    • +
  • Fixed some registry issues in the designer install.exe, which prevented some + design-time stuff from working on the Compact Framework when .NET 3.5 was + installed.
    • +
+

1.0.58.0 - August 30, 2008

+
    +
  • Code merge with SQLite 3.6.2.  If only I'd waited one more day to release + 57!  Several LINQ issues have been resolved with this engine release + relating to deeply-nested subqueries that the EF SqlGen creates.
    • +
  • The Rollback SQLiteConnection event no longer requires an open connection in + order to subscribe to it.  Missed this one in the 57 release.
    • +
+

1.0.57.0 - August 29, 2008

+
    +
  • Compiled against 3.6.1 with checkin + #3300 resolved, + which fixes an Entity Framework bug I was seeing.  I currently have 3 other + tickets out on the engine, which are not yet resolved and relate to EF.
    • +
  • Fixed decimal types to store and fetch using InvariantCulture.  If you're + using decimal datatypes in your database and were affected by the 56 release, + please issue an UPDATE <table> SET <column> = REPLACE(<column>, ',', '.');  + to fix the decimal separators.  Apologies for not testing that more + thoroughly before releasing 56.
    • +
  • Too many LINQ fixes to list.  Fixed views so they generate, + fixed the LIMIT clause, implemented additional functionality and removed unnecessary code.
    • +
  • Fixed foreign key names in the designer so viewing the SQL script on a new + unsaved table after renaming it in the properties toolwindow will reflect in the + script properly.
    • +
  • Fixed the Update and Commit events on SQLiteConnection so they don't require + the connection to be opened first.
    • +
  • Fixed userdef aggregate functions so they play nice with each other when + appearing multiple times in the same statement.
    • +
  • Fixed the editing and saving of default values in the table designer.
    • +
  • Fixed ForeignKeys schema to support multi-column foreign keys.  Also + hacked support for them in the table designer, provided two foreign keys in the + designer have the same name and reference the same foreign table and different + columns.  Will implement first-class support for this in the next release.
    • +
+

1.0.56.0 - August 11, 2008

+
    +
  • Fixed a bug in the table designer when designing new tables, wherein you had to + save the table first before being able to create indexes and foreign keys.
    • +
  • Tweaks to decimal type handling.  The 'decimal' type can't be represented + by Int64 or Double (without loss of precision) in SQLite, so we have to fudge it + by treating it like a string and converting it back and forth in the provider.  + Unfortunately backing it to the db as a string causes sorting problems.  + See this + post + for details on using a custom collation sequence to overcome the sorting issue arising from this patch.
    • +
  • Minor tweaks and bugfixes to the test program and the provider.
    • +
  • More adjustments to make the managed-only version of the provider run and pass + all tests on Mono.
    • +
  • LINQ to Entities bits heavily updated and compiled against VS2008 SP1 RTM.  SQLite + LINQ support is still considered beta.
    • +
+

1.0.55.0 - August 6, 2008

+
    +
  • Code merge with SQLite 3.6.1
    • +
  • Added support for the user-contributed extension-functions at + http://www.sqlite.org/contrib.  + Feel free to override any of them with your own implementation.  The new + functions are: acos, asin, atan, atn2, atan2, acosh, asinh, atanh, + difference, degrees, radians, cos, sin, tan, cot, cosh, sinh, tanh, coth, exp, + log, log10, power, sign, sqrt, square, ceil, floor, pi, replicate, charindex, + leftstr, rightstr, reverse, proper, padl, padr, padc, strfilter, and + aggregates stdev, variance, mode, median, lower_quartile, upper_quartile.
    • +
  • Moved the last_rows_affected() function to the C extension library.
    • +
  • Added a new class, SQLiteFunctionEx which extends SQLiteFunction and adds the + ability for a user-defined function to get the collating sequence during the + Invoke/Step methods.  User-defined functions can use the collating sequence + as a helper to compare values.
    • +
  • When registering user-defined collation sequences and functions, the provider + will now register both a UTF8 and a UTF16 version instead of just UTF8.
    • +
  • Revamped connection pooling and added static ClearPool() and ClearAllPools() + functions to SQLiteConnection.  Behavior of the pool and its clearing + mechanics match SqlClient.
    • +
  • Fixed connections going to the pool so that any unfinalized lingering commands + from un-collected datareaders are automatically reset and any lurking + transactions made on the connection are rolled back.
    • +
  • Transaction isolation levels are now partially supported.  Serializable + is the default, which obtains read/write locks immediately -- this is compatible + with previous releases of the provider.  Unspecified will default to + whatever the default isolation mode is set to, and ReadCommitted will cause a + deferred lock to be obtained.  No other values are legal.
    • +
  • Revamped the test.exe program.  It's now an interactive GUI application.  + Easier for me to add tests now.
    • +
  • Tweaks to the VS designer package and installer.
    • +
  • More adjustments to the internal SQLite3.Prepare() method to account for both + kinds of lock errors when retrying.
    • +
  • Stripped a lot of unnecessary interop() calls and replaced with base sqlite calls.  + Revamped most of UnsafeNativeMethods to make it easier to port the code.
    • +
  • Rerigged internal callbacks for userdef functions and other native to managed + callbacks.  More portable this way.
    • +
  • Source can now can be compiled with the SQLITE_STANDARD preprocessor symbol to + force the wrapper to use the stock sqlite3 library.  Some functionality is + missing, but its minimal.  None of the precompiled binaries are compiled + using this setting, but its useful for testing portability.
    • +
  • Added "boolean" and a couple other missing datatypes to the "DataTypes" schema + xml file.  Used by the VS designer when displaying tables and querying.
    • +
  • Added a new connection string option "Read Only".  When set to True, the + database will be opened in read-only mode.
    • +
  • Added a new connection string option "Max Pool Size" to set the maximum size + of the connection pool for a given db file connection.
    • +
  • Added a new connection string option "Default IsolationLevel" to set the + default isolation level of transactions.  Possible values are Serializable and + ReadCommitted.
    • +
  • Added a new connection string option "URI" as an optional parameter for + compatibility with other ports of the provider.
    • +
+

1.0.54.0 - July 25, 2008

+
    +
  • Fixed the setup project, which somehow "forgot" to include all the binaries in + the 53 release.
    • +
  • Fixed a crash in the table designer when creating a new table and tabbing past + the "Allow Nulls" cell in the grid while creating a new column.
    • +
  • Fixed a mostly-benign bug in SQLiteDataReader's GetEnumerator, which failed to + pass along a flag to the underyling DbEnumerator it creates.  This one's + been around since day 1 and nobody's noticed it in all these years.
    • +
  • Added a new connection string parameter "Journal Mode" that allows you to set + the SQLite journal mode to Delete, Persist or Off.
    • +
+

1.0.53.0 - July 24, 2008

+
    +
  • Enabled sqlite_load_extension
    • +
  • Added retry/timeout code to SQLite3.Prepare() when preparing statements for + execution and a SQLITE_BUSY error occurs.
    • +
  • Added a new schema to SQLiteConnection.GetSchema() called Triggers.  + Used to retrieve the trigger(s) associated with a database and/or table/view.
    • +
  • Extensive updates to table/view editing capabilities inside Visual Studio's + Server Explorer.  The program now parses and lets you edit CHECK constraints and + triggers on a table, as well as define triggers on views.  Experimental + still, so e-mail me if you have issues.
    • +
  • Minor bugfix to the ViewColumns schema to return the proper base column name + for a view that aliases a column.
    • +
  • Fixed the insert/update/delete DML support in the Linq module.
    • +
  • Changed the behavior of SQLiteCommand to allow a transaction to be set even if + the command hasn't been associated with a connection yet.
    • +
+

1.0.52.0 - July 16, 2008

+
    +
  • Code merge with SQLite 3.6.0
    • +
  • Added a lot of previously-missing exports to the DEF file for the + native library.
    • +
  • Fixed SQLiteDataReader to check for an invalid connection before operating on + an open cursor.
    • +
  • Implemented the Cancel() function of SQLiteCommand to cancel an active reader.
    • +
  • Added beta table and view designers to the Visual Studio Server Explorer.  You can now + edit/create tables and views, manage indexes and foreign keys from Visual Studio.  + This feature is still undergoing testing so use at your own risk!
    • +
  • Fixed the Server Explorer so VS2005 users can once again right-click tables + and views and open the table data.
    • +
  • Added some new interop code to assist in returning more metadata not normally + available through the SQLite API.  Specifically, index column sort modes + and collating sequences.  Also added code to detect (but not parse) CHECK + constraints, so the table designer can pop up a warning when editing a table + with these constraints.  Since I can't currently parse them.
    • +
  • Lots of LINQ SQL generation improvements and fixes.
    • +
  • Made some progress cleaning up and fixing up the schema definitions and + manifests for EdmGen.
    • +
  • Added a built-in SQLiteFunction called last_rows_affected() which can be + called from SQL to get the number of rows affected by the last update/insert + operation on the connection.  This is roughly equivalent to Sql Server's + @@ROWCOUNT variable.
    • +
+

1.0.51.0 - July 1, 2008

+
    +
  • VS2008 SP1 Beta1 LINQ Support
    • +
  • Added experimental Entity Framework support in a new library, + System.Data.SQLite.Linq.  Some things work, some don't.  I haven't + finished rigging everything up yet.  The core library remains stable.  + All LINQ-specific code is completely separate from the core.
    • +
  • Added some columns to several existing schemas to support some of the + EDM framework stuff.
    • +
  • Minor tweaks to the factory to better support dynamic loading of the Linq + extension library for SQLite.
    • +
  • SQLite's busy handler was interfering with the provider's busy handling + mechanism, so its been disabled.
    • +
+

1.0.50.0 - June 27, 2008

+
    +
  • Fixed some lingering dispose issues and race conditions when some objects were finalized.
    • +
  • Fixed the SQLiteConvert.Split() routine to be a little smarter when splitting + strings, which solves the quoted data source filename problem.
    • +
  • Enhanced the mergebin utility to work around the strong name validation bug on + the Compact Framework.  The old workaround kludged the DLL and caused WM6.1 + to fail to load it.  This new solution is permanent and no longer kludges + the DLL.
    • +
+

1.0.49.0 - May 28, 2008

+
    +
  • Code merge with SQLite 3.5.9
    • +
  • Fixed schema problems when querying the TEMP catalog.
    • +
  • Changed BLOB datatype schema to return IsLong = False instead of True.  This + was preventing DbCommandBuilder from using GUID's and BLOB's as primary keys.
    • +
  • Fix rollover issue with SQLite3.Reset() using TickCount.
    • +
  • Fixed SQLiteDataReader to dispose of its command (if called for) before + closing the connection (when flagged to do so) instead of the other way around.
    • +
  • Fixed a DbNull error when retrieving items not backed by a table schema.
    • +
  • Fixed foreign key constraint parsing bug.
    • +
  • Added FailIfMissing property to the SQLiteConnectionStringBuilder.
    • +
  • Converted the source projects to Visual Studio 2008.
    • +
+

1.0.48.0 - December 28, 2007

+
    +
  • Code merge with SQLite 3.5.4
    • +
  • Calling SQLiteDataReader.GetFieldType() on a column with no schema information + and whos first row is initially NULL now returns type Object instead of type DbNull.
    • +
  • Added support for a new DateTime type, JulianDay.  SQLite uses Julian dates + internally.
    • +
  • Added a new connection string parameter "Default Timeout" and a corresponding + method on the SQLiteConnection object to change the default command timeout.  + This is especially useful for changing the timeout on transactions, which use SQLiteCommand + objects internally and have no ADO.NET-friendly way to adjust the command timeout + on those commands.
    • +
  • FTS1 and FTS2 modules were removed from the codebase.  Please upgrade all + full-text indexes to use the FTS3 module. 
    • +
+

1.0.47.2 - December 10, 2007

+
    +
  • Fixed yet one more bug when closing a database with unfinalized command objects
    • +
  • Fixed the DataReader's GetFieldType function when dealing with untyped SQLite affinities
    • +
+

1.0.47.1 - December 5, 2007

+
    +
  • Fixed a leftover bug from the codemerge with SQLite 3.5.3 that failed to close a database.
    • +
  • Fixed the broken Compact Framework distribution binary.
    • +
  • SQLite 3.5.x changed some internal infrastructure pieces in the encryption interface + which I didn't catch initially.  Fixed. 
    • +
+

1.0.47.0 - December 4, 2007

+
    +
  • Code merge with SQLite 3.5.3
    • +
  • Added installer support for Visual Studio 2008.  Code is still using the + VS2005 SDK so one or two bells and whistles are missing, but nothing significant.
    • +
  • This is the last version that the FTS1 and FTS2 extensions will appear.  + Everyone should rebuild their fulltext indexes using the new FTS3 module.  + FTS1 and FTS2 suffer from a design flaw that could cause database corruption with + certain vacuum operations.
    • +
  • Fixed pooled connections so they rollback any outstanding transactions before + going to the pool. 
    • +
  • Fixed the unintended breaking of the TYPES keyword, and mis-typing of untyped + or indeterminate column types.
    • +
  • Assert a FileIOPermission() requirement in the static SQLiteFunction constructor. +
    • +
  • The CE-only SQLiteFunction.RegisterFunction() is now available on the desktop + platform for dynamic registration of functions.  You must still close and re-open + a connection in order for the new function to be seen by a connection.
    • +
  • Fixed the "database is locked" errors by implementing behavioral changes in the + interop.c file for SQLite.  Closing a database force-finalizes any prepared + statements on the database to ensure the connection is fully closed.  This + was rather tricky because the GC thread could still be finalizing statements itself. +  
    • +
  • Modifed the mergebin utility to help circumvent a long-standing strong name verification + bug in the Compact Framework.
    • +
+

1.0.46.0 - September 30, 2007

+
    +
  • Fixed faulty logic in type discovery code when using SQLiteDataReader.GetValue().
    • +
  • Fixed Connection.Open() bug when dealing with :memory: databases.
    • +
  • Fixed SQLiteCommand.ExecuteScalar() to return a properly-typed value.
    • +
  • Added support for SQLiteParameter.ResetDbType().
    • +
  • Added test cases for rigid and flexible type testing.
    • +
+

1.0.45.0 - September 25, 2007

+
    +
  • Breaking change in GetSchema("Indexes") -- MetaDataCollections + restrictions and identifier parts counts were wrong for this schema and I was using + the wrong final parameter as the final restriction.  Meaning, if you use the + Indexes schema and are querying for a specific index the array should now be {catalog, + null, table, index } instead of {catalog, null, table, null, index}
    • +
  • Code merge with SQLite 3.4.2
    • +
  • Fixed some errors in the encryption module, most notably when a non-default page + size is specified in the connection string.
    • +
  • Fixed SQLiteDataReader to better handle type-less usage scenarios, which also + fixes problems with null values and datetimes.
    • +
  • Fixed the leftover temp files problem on WinCE
    • +
  • Added connection pooling.  The default is disabled for now, but may change + in the future.  Set "Pooling=True" in the connection string to enable it.
    • +
  • Sped up SQLiteConnection.Open() considerably.
    • +
  • Added some more robust cleanup code regarding SQLiteFunctions.
    • +
  • Minor additions to the code to allow for future LINQ integration into the main + codebase.
    • +
  • Fixed a long-standing bug in the Open() command of SQLiteConnection which failed + to honor the documented default behavior of the SQLite.NET provider to open the + database in "Synchronous=Normal" mode.  The default was "Full".
    • +
  • If Open() fails, it no longer sets the connection state to Broken.  It instead + reverts back to Closed, and cleans up after itself.
    • +
  • Added several new parameters to the ConnectionString for setting max page count, + legacy file format, and another called FailIfMissing to raise an error rather than + create the database file automatically if it does not already exist.
    • +
  • Fixed some designer toolbox references to the wrong version of the SQLite.Designer
    • +
  • Fixed a bug in the mergebin utility with regards to COR20 metadata rowsize computations.  +
    • +
  • Minor documentation corrections   
    • +
+

1.0.44.0 - July 21, 2007

+
    +
  • Code merge with SQLite 3.4.1
    • +
  • Fixed a bug in SQLiteConnection.Open() which threw the wrong kind of error in + the wrong kind of way when a database file could not be opened or created. 
    • +
  • Small enhancements to the TYPES keyword, and added documentation for it in the + help file.
    • +
  • Hopefully fixed the occasional SQLITE_BUSY errors that cropped up when starting + a transaction.  Usually occurred in high-contention scenarios, and the underlying + SQLite engine bypasses the busy handler in this scenario to return immediately.
    • +
+

1.0.43.0 - June 21, 2007

+
    +
  • Code merge with SQLite 3.4.0
    • +
  • Fixed a reuse bug in the SQLiteDataAdapter in conjunction with the SQLiteCommandBuilder.  + It's been there unnoticed for more than a year, so it looks like most folks never + encountered it.
    • +
  • Fixed an event handler bug in SQLiteCommandBuilder in which it could fail to unlatch + from the DataAdapter when reused.  Relates to the previous bugfix.
    • +
  • Fixed a double-dispose bug in SQLiteStatement that triggered a SQLiteException. 
    • +
+

1.0.42.0 - June 1, 2007

+
    +
  • Code merge with SQLite 3.3.17
    • +
  • Changed the SQLiteFunction static constructor so it only enumerates loaded modules + that have referenced the SQLite assembly, which hopefully should cut down dramatically + the time it takes for that function to execute. 
    • +
  • Added the FTS2 full-text search extension to the project.  Look for FTS1 + to disappear within the next couple of revisions. 
    • +
  • Fixed a bug introduced with the finalizers that triggered an error when statements + ended with a semi-colon or had other non-parsable comments at the end of a statement 
    • +
  • Fixed an intermittent multi-threaded race condition between the garbage collector + thread and the main application thread which lead to an occasional SQLITE_MISUSE + error.
    • +
  • Fixed another issue relating to SQLite's inherent typelessness when dealing with + aggregate functions which could return Int64 or Double or even String for a given + row depending on what was aggregated.
    • +
  • Remembered to recompile the DDEX portion of the engine this time, so Compact Framework + users can once again use the design-time functionality
    • +
+

1.0.41.0 - April 23, 2007

+
    +
  • Code merge with SQLite 3.3.16
    • +
  • Second go at implementing proper finalizers to cleanup after folks who've forgotten to Dispose() of the SQLite objects
    • +
  • Enhanced GetSchema(IndexColumns) to provide numeric scale and precision values
    • +
  • Fixed the column ordinals in GetSchema(IndexColumns) to report the ordinal of the column in the index, not the table
    • +
  • Fixed a bug whereby parameters named with an empty string (such as String.Empty) were treated like a named parameter instead of an unnamed parameter
    • +
+

1.0.40.0 - January 31, 2007

+
    +
  • Code merge with SQLite 3.3.12
    • +
  • Lots of new code to handle misuse of the library.  Implemented finalizers + where it made sense, fixed numerous garbage collector issues when objects are not + disposed properly,  fixed some object lifetime issues, etc.
    • +
  • A failed Commit() on a transaction no longer leaves the transaction in an unusable + state.
    • +
+

1.0.39.1 - January 11, 2007

+
    +
  • Fixed a really dumb mistake that for some reason didn't trigger any errors in + the testcases, whereby commands when associated with a connection were not adding + or removing themselves from an internal list of commands for that connection -- + causing a "database is locked" error when trying to close the connection.
    • +
+

1.0.39.0 - January 10, 2007

+
    +
  • Code merge with SQLite 3.3.10
    • +
  • Fixed a multi-threaded race condition bug in the garbage collector when commands + and/or connections are not properly disposed by the user.
    • +
  • Switched the encryption's internal deallocation code to use sqlite's built-in + aux functions instead of modifying the pager.c source to free the crypt block.  + This eliminates the last of the code changes the provider makes to the original + sqlite engine sources.  Props to Ralf Junker for pointing that out.
    • +
+

1.0.38.0 - November 22, 2006

+
    +
  • Fixed a bug when using CommandBehavior.KeyInfo whereby integer primary key columns may be duplicated in the results.
    • +
  • Enhanced the CommandBuilder so that update/delete statements are optimized when the affected table contains unique constraints and + a primary key is present.
    • +
  • Fixed a bug in the DataReader when used in conjunction with CommandBehavior.CloseConnection.
+

1.0.37.0 - November 19, 2006

+
    +
  • Added support for CommandBehavior.KeyInfo.  + When specified in a query, additional column(s) will be returned describing the + key(s) defined for the table(s) selected in the query.  This is optimized when + INTEGER PRIMARY KEY is set for the given tables, but does additional work for other + kinds of primary keys.
    • +
  • Removed the default values from SQLiteDataReader.GetTableSchema(), to better follow + Sql Server's pattern and suppress schema errors when loading the records into a + dataset/datatable.
    • +
  • Allow integers to implicitly convert to double/decimal/single.
+

1.0.36.1 - October 25, 2006

+
    +
  • Added support for LONGVARCHAR, SMALLDATE and SMALLDATETIME. These were actually added in 1.0.36.0 but were undocumented.
    • +
  • Fixed the embedded helpfile which was accidentally built from old sources.
    • +
  • Fixed an unfortunate re-entry of a bug in the .36 codebase that caused the provider to "forget" about commands on a connection under certain circumstances.
    • +
+

1.0.36.0 - October 23, 2006

+
    +
  • Code merge with SQLite 3.3.8, including support for full-text search via the FTS1 + extension. 
  • Fixed a bug retrieving data types when UseUtf16Encoding is true. Side-effect of further merging the common code between the two base classes.
    • +
  • Fixed a bug with System.Transactions whereby a connection closed/disposed within + a transaction scope is rolled back and cannot be committed.
    • +
  • Added more error checking and reporting to transactions to help user's isolate + the source of transaction failures.
    • +
  • Implemented a workaround for a Compact Framework issue regarding strong-named + assemblies containing a PE section with a raw size less than the virtual size. 
    • +
+

1.0.35.1 - September 12, 2006

+
    +
  • Fixed the TYPES keyword to work when UseUTF16Encoding is true.
    • +
  • Fix another bug revealed in 1.0.35.0 regarding infinite loops when the 2nd or subsequent statements of a semi-colon separated command cannot be parsed.
    • +
  • Updated the help documentation. 
    • +
+

1.0.35.0 - September 10, 2006

+
    +
  • Fixed an infinite loop bug in SQLiteCommand caused when multiple semi-colon separated + statements in a single command are executed via datareader and one of the statements + contains a syntax error preventing it from being prepared. 
  • Added the TYPES preparser keyword to be placed before a SELECT statement to + aid the wrapper in converting expressions in a subsequent select clause into more + robust types.  Documentation yet to be integrated, but available on the forums.
    • +
  • Added a new connectionstring parameter "BinaryGUID=true/false" (default is "true").  + When true, guid types are stored in the database as binary blobs to save space.  + Binary has been the default format since 1.0.32.0 but this parameter eases backward + compatibility.
    • +
+

1.0.34.0 - September 4, 2006

+
    +
  • Fixed a bug in SQLiteParameterCollection.RemoveAt(namedparam)
    • +
  • Fixed a bug in SQLiteDataReader introduced in 1.0.30 that broke DateTimes using the Ticks option in the connection string.
    • +
  • Fixed a bug in the recent changes to guid behavior wherein using a datareader's + indexer to fetch a guid from a column containing both binary and text guids would + sometimes return a byte array instead of a guid.
    • +
  • Enacted a workaround involving typed datasets in Compact Framework projects in + which it took an excessive amount of time to open a form and generated a lot of + temporary files in the user's Local Settings\Application Data\Microsoft\VisualStudio\8.0\Assembly + References folder.
    • +
+

1.0.33.0 - August 21, 2006

+
    +
  • Code merge with SQLite 3.3.7
    • +
  • Fixed a bug in SQLiteConnection that caused it to "forget" about commands bound + to it and occasionally throw an error when a database is closed and opened repeatedly.  +
    • +
+

1.0.32.0 - August 6, 2006

+
    +
  • Added AllowPartiallyTrustedCallers attribute to the assembly
  • Added the missing "nchar" type
    • +
  • Added support for binary Guid's.  Guids are now stored as binary by default + when using parameterized queries.  Text guids are still fully supported.
    • +
  • Fixed a TransactionScope() error that caused the transaction not to be completed.
    • +
  • Enhanced parameter names so that if they are added to the Parameters collection + without their prefix character (@ : or $) they are still properly mapped. 
    • +
+

1.0.31.0 - July 16, 2006

+
    +
  • Re-applied the view parsing bugfix in 1.0.29.0 that was accidentally reverted + out of the 30 build.
  • Fixed SQLiteCommand.ExecuteScalar() to return null instead of DbNull.Value + when no rows were returned.
    • +
  • Design-time installer now installs the package-based designer on full Visual Studio + versions.  Express editions continue to use the packageless designer.
    • +
  • In Visual Studio (not Express), you can now right-click a SQLite connection in + the Server Explorer and vacuum the database and change the encryption password.
    • +
+

1.0.30.1 - July 2, 2006

+
    +
  • Code merge with SQLite 3.3.6
    • +
  • Added support for the |DataDirectory| keyword in the Data Source filename string.  +
    • +
  • Added hook notification support to SQLiteConnection.  Specifically, there + are three new events on the SQLiteConnection object which are raised when an update/insert/delete + occurs and when transactions are committed and rolled back.
  • Changed SQLiteTransaction to default to BEGIN IMMEDIATE instead of just BEGIN, + which solves a multithreaded race condition. 
    • +
  • Changed SQLiteDataReader to better support SQLite's typelessness.  The data + reader no longer caches column affinity, but re-evaluates it for each column/row.
    • +
  • Fixed a bug in Prepare() which caused an intermittant fault due to the code accessing + the memory of an unpinned variable. 
    • +
  • Fixed a multithreaded lock-retry bug in in SQLiteConnection.Open() and in + SQLiteTransaction, which failed to use a command timeout before giving up.
    • +
+

1.0.29.0 - May 16, 2006

+
    +
  • Fixed a bug in the Views schema information which caused multi-line view definition statements not to be parsed
    • +
  • Fixed a parsing bug in SQLiteDataReader.GetSchemaTable() to account for numeric(x,y) datatypes with specified precision and scale
    • +
  • Fixed a bug in SQLiteConnection.Open() which tried to automatically enlist in an ambient transaction but had not yet set the state of the database to Opened, thereby causing a transaction fault
    • +
  • Changed SQLiteException to inherit from DbException on the full framework
    • +
+

1.0.28.0 - April 14, 2006

+
    +
  • Code merge with SQLite 3.3.5
    • +
  • You can now specify a relative path in the Compact Framework's "Data Source" by + prefixing the file with ".\".  i.e. "Data Source=.\\mydb.db3"
    • +
  • Several more changes and enhancements to schemas for better compatibility.
    • +
  • Fixed several bugs with the 64-bit builds of the provider.  The x64 binary + is now optimized.
    • +
  • Design-time installer now tries to install the 64-bit builds into the GAC along + with the 32-bit build.
    • +
  • Fixed a bug in the SQLiteDataReader.GetSchemaTable() function when used with tables + containing apostrophes.
    • +
  • Fixed an XSD-related bug whereby the XSD utility was unable to locate the provider + and could not generate typed datasets.
    • +
  • Added NTEXT and STRING datatypes to the list of recognized keywords (used for + schema retrieval).
    • +
  • Due to the XSD bug and other potential problems related to external build utilities, + changes to the installation of the designer have had to be made.  The installer + used to write the DbProviderFactories XML into the devenv.exe.config file and its + express cousins, but now has to write instead to the machine.config.
    • +
  • Installer writes to both the 32-bit machine.config and the 64-bit machine.config + if it exists. 
    • +
+

1.0.27.1 - February 28, 2006

+
    +
  • Fixed a bug when doing data binding in Compact Framework projects that prevented + you from assigning a typed dataset to a bindingsource.  It turns out, the CF + version of the SQLite provider needs to be flagged as retargetable so it'll work + in the design-time desktop environment.  No changes were made to the desktop + build, but the revision was bumped on all libraries anyway in order to keep them + sync'd. 
+

1.0.27.0 - February 27, 2006

+
    +
  • Many optimizations and a few more minor adjustments to schemas and schema retrieval + performance.
    • +
  • Lots of design-time attributes added to the code.  The DbDataAdapter, DbCommand, + and DbConnection objects now have greatly enhanced design-time capabilities when + added to the toolbox and dropped on a form.
    • +
  • Lots of Server Explorer enhancements.
    • +
  • Binaries are now distributed in a setup program for easier administration and + configuration of the provider.
    • +
+

1.0.26.2 - February 15, 2006

+
    +
  • Yet another bugfix to index schemas, which was incorrectly marking most indexes + as primary key indexes.
  • Fixed GetSchema() to accept a null string array.
  • Fixed a misspelled export in the core C library that prevented databases opened + with UTF16Encoding from getting schema information and would likely cause an error + if attempted.
+

1.0.26.1 - February 14, 2006

+
    +
  • Fixed even more minor schema bugs having to do with indexes.
  • Added two missing pieces in the SQLite designer which were preventing it from + being used from within VS Express editions. 
  • Several bugfixes to the design-time installer program, including supporting + 64-bit environments.
+

1.0.26.0 - February 11, 2006

+
    +
  • Code merge with SQLite 3.3.4
  • Fixed an encryption bug when changing the password of databases over 1gb in + size. 
  • Fixed various designer issues related to construction of named parameters.
    • +
  • Retooled the GetSchema() method of SQLiteDataReader to use the new 3.3.4 API functions, + and made several enhancements and fixes to schemas. 
    • +
  • Implemented the SourceColumnNullMapping property of SQLiteParameter to fix + a DbCommandBuilder code generation bug. 
  • Removed the runtime dependency on MSVCR80.DLL.  File size is somewhat + larger for the varying desktop versions.
  • Created an install program to manage installation and uninstallation of the + SQLite design-time support.
    • +
  • Designer support now works for all Visual Studio editions, including all Express + Editions.
    • +
  • Design-time installer will now remove (if present) the machine.config SQLite entries + in favor of installing the xml code into the devenv.exe.config file (or any of the + variations for express editions).  The officially-accepted behavior of using + DbProviderFactories is to add the code to your app.config file, and the machine.config + file should not be touched.
    • +
+

1.0.25.0 - January 31, 2006

+
    +
  • Code merge with SQLite 3.3.3
  • Added automatic distributed transaction enlistment and implemented the DbConnection.EnlistTransaction + method for manual enlistment.
    • +
  • Nested transactions are now supported.
    • +
  • Rearranged the timing of SetPassword(), which now must be called before the database + is opened instead of afterwards.  Optionally, the password can be supplied + in the ConnectionString.
    • +
  • Fixed a bug in SQLiteFunction that caused a failure when an empty resultset was + returned and a custom user aggregate function was used in the query.
    • +
  • The designer has had another round of cleanup applied, in preparation for moving + to a VS package.
    • +
  • Added SQLiteMetaDataCollectionNames class.
    • +
+

1.0.24.6 beta - January 23, 2006

+
    +
  • This beta is built from sqlite.org's 3.3.2 beta.
  • Eliminated the static linking of mscoree from all binaries.  Native projects + can now use the library without any dependencies on the .NET framework, while managed + projects continue to be able to use the library normally.
+

1.0.24.5 beta - January 20, 2006

+
    +
  • This beta is built from sqlite.org's 3.3.1 alpha and contains development-in-progress code.  Therefore no guarantees + can be made regarding its suitability for production use.
    • +
  • You no longer need to distribute 2 files on the CompactFramework.  + You can delete SQLite.Interop.DLL entirely.  I wrote a custom tool + called "mergebin" (available in the source zip file) which combines the two libraries + and gets around a glaring defect in the VS2005 linker for ARM processors which doesn't + allow you to link netmodules.
    • +
  • x64 and ia64 builds now use the same strong name as the x86 build.  + This means breaking backward compatibility, but it was necessary in order to allow + you to drop any of those 3 builds onto a PC and have your .NET program run properly.  + Prior to this, you'd get an error if you built your program using the x86 build, + and then installed the x64 version on a target machine and tried to run your program + against it.
    • +
  • The entire source project has been gone over top to bottom.  A debug build + no longer combines the binaries into a single module, which was preventing proper + debugging.
+

1.0.24.4 beta - January 16, 2006

+
    +
  • This beta is built from sqlite.org's 3.3.1 alpha and contains development-in-progress code.  Therefore no guarantees + can be made regarding its suitability for production use.
    • +
  • Fixed a bug in the UTF-16 handling code for preparing statements due to a behavioral + change in SQLite 3.3.0.
    • +
  • Added pager.c code necessary to cleanup after an encrypted file is closed.
    • +
  • Fixed an encryption bug that caused a fault when an encrypted file was rolled + back.
    • +
  • Modified the testcase code to take advantage of optimizations regarding the use + of a DbCommandBuilder.  DataAdapter insert speed increased dramatically as + a result.
    • +
+

1.0.24.3 beta - January 10, 2006

+
    +
  • This beta is built from sqlite.org's 3.3.0 alpha and contains development-in-progress code.  Therefore no guarantees + can be made regarding its suitability for production use.
  • Added support for database encryption at the pager level.  Databases + are encrypted using a 128-bit RC4 stream algorithm.  To open an existing encrypted + database, you may now specify a "Password={password}" text in the ConnectionString, + or you may call the SQLiteConnection.SetPassword() function to set the password + on an open connection.  To encrypt existing non-encrypted databases or to change + the password on an encrypted database, you must use the SQLiteConnection.ChangePassword() + function.  If you use SetPassword() instead of specifying a password in the + connection string, or call ChangePassword() you may use a binary byte array or a + text string as the password.
    • +
  • Rewrote the locking implementation for the Compact Framework.  It is now + more robust and incorporates into the SQLite codebase more efficiently than the + previous CE adaptation.
    • +
  • Moved some of the embedded schema XML data into a resource file to ease code readability.
    • +
  • Automated the fixup of the original sqlite codebase's source prior to compiling, + to ease merging with sqlite.org's source.
    • +
  • Fixed a memory leak in SQLiteCommand due to it not removing an internal reference + to itself in SQLiteConnection. 
    • +
+

1.0.24.2 - December 30, 2005

+
    +
  • Fixed the SQLiteDataReader.HasRows property to return the proper value.
    • +
  • Implemented the inadvertently neglected RecordsAffected property on SQLiteDataReader. +
    • +
  • SQLiteFunction static constructor was changed to pre-filter classes with only the + SQLiteFunctionAttribute.  The code was throwing an exception when certain + assemblies were referenced in a project.
    • +
  • Fixed the SQLiteDataAdapter OnRowUpdated event, which was using the wrong variable + to find the attached event handler and subsequently not raising the event.
    • +
  • Small optimizations and fixes to SQLiteDataReader.NextResult(). 
    • +
+

1.0.24.1 - December 19, 2005

+
    +
  • Update core SQLite engine to 3.2.8 
+

1.0.24 - December 9, 2005

+
    +
  • Fixed the Catalogs schema bug that caused attached databases not to be re-attached to a cloned connection +
    • +
  • Enhanced transactions to allow for a deferred or immediate writelock.  SQLiteConnection.BeginTransaction() + now has an additional overload to support it 
  • Commands are now prepared as they are executed instead of beforehand.  This + fixes a bug whereby a multi-statement command that alters the database and subsequently + references the altered data would fail during Prepare().
  • Tightened up the SQLiteDataReader to prevent reading columns before calling + the first Read() and to prevent reading columns after the last Read().
    • +
  • A more descriptive error is thrown if there aren't enough parameters in the command + to satisfy the parameters required by the statement(s). 
    • +
+

1.0.23 - November 21, 2005

+
    +
  • Named parameters may now begin with @ to ease portability of + the provider. SQLite's named parameters are ordinarily prefixed with a : + or $.  The designer will still use the $ + prefix however, since its more compatible with the default SQLite engine.
  • Added several alternate ISO8601 date/time formats to SQLiteConvert.cs to increase + compatibility.
    • +
  • Relaxed coersion restrictions to work better with SQLite's inherent typelessness. 
    • +
+

1.0.22 - November 11, 2005

+
    +
  • Fixed some globalization issues which resulted in incorrect case-insensitive comparisons
    • +
  • Fixed a bug in the routine that finds all user-defined functions in a loaded assembly.  + It would throw an exception if any of the types in the assembly could not be loaded.  + The exception is now caught and handled appropriately.
    • +
+

1.0.21 - November 4, 2005

+
    +
  • Fixed a designer bug when creating typed datasets with parameterized queries.
    • +
  • The above fix then exposed another bug in the datareader's ability to query schema + information on parameterized commands, which was also fixed.
    • +
  • Compiled against the RTM version of VS2005.
    • +
  • Rewrote the design-time install script to use the XML DOM objects when writing + to the machine.config and to automatically register the DLL in the GAC.
  • Made changes to the app.config descriptions and help file to improve version-independent + factory support.
+

1.0.20 - October 19, 2005

+
    +
  • + Fixed a shortcut in SQLiteBase.GetValue which was insufficient for + international environments.  The shortcut was removed and the "proper" + procedure put in.
+

1.0.19 - October 5, 2005

+
    +
  • + Code merge with SQLite 3.2.7 +
  • + Fixed bugs in the CE port code (os_wince.c) which were brought to + light by recent changes in the SQLite engine. +
  • + Recompiled and modified to be compatible with the September VS2005 Release + Candidate.
    + Beta 2 users should continue to use 1.0.18.1
+

1.0.18.1 - September 19, 2005

+
    +
  • + Code merge with SQLite 3.2.6
+

1.0.18 - September 1, 2005

+
    +
  • + Added type-specific method calls when using the various SQLite classes that + would've normally returned a a generic Db base class, which aligns the code + better with the Microsoft-supplied data providers.
+

1.0.17 - August 26, 2005

+
    +
  • + Code merge with SQLite 3.2.5 +
  • + Added Itanium and x64 build settings to the project (needs testing) +
  • + Bugfixes and enhancements to several schema types +
  • + Additional design-time support to include index and foreign key + enumerations.  Requires re-registering the designer using + INSTALL.CMD.  The new designer code now allows the VS query designer and + typed datasets to automatically link up foreign keys, use indexes, and + automatically generate relationships from the schema.
  • + Additional static methods on SQLiteConnection to create a database file, + encrypt a file using the Encrypted File System (EFS) on NTFS (requires NT 2K or + above) and NTFS file compression
    • +
+

1.0.16 - August 24, 2005

+
    +
  • + Code merge with SQLite 3.2.4 with the large delete bugfix in CVS (which will + become 3.2.5 soon) +
  • + Added new GetSchema() types: IndexColumns, ViewColumns, ForeignKeys
    • +
+

1.0.15 - August 22, 2005
+

+
    +
  • + Code merge with SQLite 3.2.3 +
  • + Minor updates for better design-time experience. More design-time code to + follow in subsequent releases.
    • +
+

1.0.14 - August 16, 2005
+

+
    +
  • + Fixed a bug in the SQLiteDataAdapter due to insufficient implementation of the + class.  The RowUpdating and RowUpdated events are now properly + implemented, but unfortunately inserting and updating data in a DataTable or + DataSet is now much slower.  This is the proper design however, so the + changes are here to stay. +
  • + Lots of schema changes to support Visual Studio's Data Designer architecture.
  • Added + Designer support for the provider.  It's not 100%, but you can design + queries, add typed datasets and perform quite a number of tasks all within + Visual Studio now.
+

1.0.13 - August 8, 2005
+

+
+
    +
  • + Fixed a named parameter bug in the base SQLite_UTF16 class, which of course + only showed up when a database connection was opened using the + UseUTF16Encoding=True parameter. +
  • + Fixed a performance issue in SQLite_UTF16 involving string marshaling.
+
+

1.0.12 - August 5, 2005
+

+
+
    +
  • + Full support for the Compact Framework.  Each build (Debug/Release) now + has a platform, either Win32 or Compact Framework.  The correct + projects are built accordingly.  See the Distributing + SQLite + section for information on what files need to be distributed for each + platform.  +
  • + Modified SQLite3.Reset() and Step() functions to transparently handle timeouts + while waiting on the database to become available (typically when a writer is + waiting on a reader to finish, or a reader is waiting on a writer to finish). +
  • + Lots of code cleanup as suggested by the Code Analyzer (FxCop). +
  • + Lots of updates to the helpfile (as you can see). +
  • + Statements were already prepared lazily in a SQLiteCommand, but now + its even more lazy.  Statements are now only prepared if the statements + haven't been previously prepared and a Prepare() function is called (and the + command is associated with a connection) or just prior to the command being + executed. 
+
+

1.0.11 - August 1, 2005
+

+
    +
  • + For everything except the Compact Framework, System.Data.SQLite.DLL is + now the only DLL required to use this provider!  The + assembly is now a multi-module assembly, containing both the native SQLite3 + codebase and the C# classes built on top of it.  The Compact Framework + version (when completed) will not be able to support this feature, so backwards + compatibility with the Compact Framework has been preserved for the future. +
  • + Fixed a bug in SQLiteCommand.ExecuteScalar() that caused it to stop executing + commands once it obtained the first column of the first row-returning + resultset.  Any remaining statements after the row-returning statement was + ignored. +
    • +
+

1.0.10 - June 10, 2005
+

+
    +
  • + Fixed a bug in the SQLite3.cs Prepare() function that created a statement even + when the SQLite engine returned a NULL pointer. Typically this occurs when + multiple statements are processed and there are trailing comments at the end of + the statement. +
  • + Fixed a bug in SQLiteStatement.cs that retrieved parameter names for a + parameterized query.  SQLite's parameters are 1-based, and the function + was starting at 0.  This was fine when all parameters were unnamed, but + for named parameters it caused the parameters to be out of whack. +
    • +
+

1.0.09a - May 25, 2005
+

+
    +
  • + Fixed a broken helpfile and corrected some obsolete help remarks in + SQLiteFunction.cs +
  • + Added a version resource to the SQLite.Interop.DLL. 
+

1.0.09 - May 24, 2005
+

+
    +
  • + Code merge with the latest 3.21 version of SQLite. +
  • + Removed obsolete methods and properties for Whidbey Beta 2
+

1.0.08 Refresh - Mar 24, 2005
+ +

+
    +
  • + Code merge with the latest 3.20 version of SQLite. +
  • + Recompiled the help file to fix a build error in it. +
    • +
+

1.0.08 - Mar 11, 2005
+ +

+
    +
  • + Added additional #if statements to support the old beta 1 edition of VS2005. +
  • + Code merged the SQLite 3.14 source. +
    • +
+

1.0.07 - Mar 5, 2005
+

+
    +
  • + Made more optimizations to frequently-called functions, resulting in + significant performance gains in all tests. +
  • + Recompiled the binaries using the latest VS2005 February CTP, resulting in yet + more significant speed gains.  The 100k insert test used to take 3.5 + seconds and the insertwithidentity took almost 8 seconds.  With the above + two changes, those tests are now executing in 1.9 and 4.9 seconds respectively.
+

1.0.06 - Mar 1, 2005
+ +

+
    +
  • + Speed-ups to SQLiteDataReader.  It was interop'ing unnecessarily every + time it tried to fetch a field due to a logic error. +
  • + Changed/Added some code to SQLiteConvert's internal DbType, Type and + TypeAffinity functions. +
  • + Fixed the SQLiteDataReader to obey the flags set in the optional + CommandBehavior flag from SQLiteCommand.ExecuteReader(). +
  • + Changed the default page size to 1024 to reflect the defaults of SQLite.  + Ignores the "Page Size" connection string option for memory databases, as tests + revealed that changing it resulted in memory corruption errors. +
  • + Performance enhancements to the SQLiteCommand and SQLiteStatement classes which + reduced the 100,000 row insert execution time as well as the various Function + execution times significantly. +
    • +
+

1.0.05 - Feb 25, 2005 +

+
    +
  • + Fixed the SQLite3 C# class step/reset functions to accomodate schema changes + that invalidate a prepared statement.  Statements are recompiled + transparently. +
  • + Moved all native DLL declarations to an UnsafeNativeMethods class. +
  • + Split several classes into their own modules for readability. +
  • + Renamed many internal variables, reviewed access to variables marked as + internal and altered their protection levels accordingly. +
  • + Due to the presence of the altered sqlite3 codebase and so many added interop + functions, I decided to rename the sqlite3 C project and the DLL to + SQLite.Interop.DLL.  This is the same core sqlite3 codebase but designed + specifically for this ADO.NET provider.  This eliminates any possibility + of someone dropping another build of sqlite3.dll into the system and rendering + the provider inoperable.  In the future if the folks at sqlite.org finally + introduce a method of retrieving column usage for an arbitrary prepared + statement, I'll retool this library to be a lightweight function call wrapper + around the core binary distribution. +
  • + Added [SuppressUnmanagedCodeSecurity] attribute to the UnsafeNativeMethods + class which brings VS2005 November CTP execution speeds inline with the + December CTP. +
  • + Added a bin + directory to the project root where pre-compiled binaries can be found. +
  • + Added a doc + directory where preliminary documentation on the class library can be found. +
  • + Documented a lot more of the classes internally. +
    • +
+

1.0.04 - Feb 24, 2005 +

+
    +
  • + Removed the SQLiteContext class and revamped the way UserFunctions work to + simplify the imlementation. +
  • + Fixed a counting bug in the TestCases class, specifically in the function tests + where I wasn't resetting the counter and it was consequently reporting + intrinsic and raw select calls as being much much faster than they actually + were.  The numbers are now much closer to what I expected for performance, + with .NET user-functions still being the slowest, but only by a small margin. +
  • + Small performance tweaks to SQLiteDataReader. +
  • + Added PageSize to the SQLiteConnectionStringBuilder and subsequently to the + SQLiteConnection +
  • + Added a PRAGMA encoding=XXX execution statement to the SQLiteConnection after + opening a connection. +
    • +
+

1.0.03 - Feb 23, 2005 +

+
    +
  • + Fixed up SQLiteCommandBuilder to correct implementation errors, which resulted + in an enormous performance boost in the InsertMany test.   10,000 row + insert that executed in 1500ms now executes in 500ms. +
  • + Fixed several errors in the SQLite3_UTF16 class.  ToString() was working + incorrectly and the Open() method failed to register user defined functions and + collations. +
  • + Fixed a bug in SQLiteCommand.ClearCommands() whereby only the first statement + was being properly cleaned up. +
  • + Fixed a bug in SQLiteDataReader whereby calling NextResult() would not properly + reset the previously-executed command in the sequence. +
  • + Added an InsertManyWithIdentityFetch test, which appends a select clause to + populate the ID of the last inserted row into the InsertCommand, demonstrating + ADO.NET's ability to auto-fetch identity columns on insert. +
    • +
+

1.0.02 - Feb 21, 2005

+
    +
  • + Tweaks to the xxx_interop functions that return char *'s, so they also return + the length.  Saves an interop call to get the UTF-8 string length during + conversion to a .NET string. +
  • + Reworked the whole interop.c thing into interop.h and reduced the code required + to merge the main sqlite3 codebase. +
  • + Added support for user-defined collations. +
    • +
