Exposed as <i>Catalogs</i> in the schema. When cloning a connection, all attached databases are automatically re-attached to the new connection.</li> <li>DbConnection.GetSchema(...) support includes the <i>MetaDataCollections</i>, <i> DataSourceInformation</i>, <i>Columns</i>, <i>Tables</i>, <i>Views</i>, <i>Catalogs</i> and <i>Indexes</i> keywords.</li> <li>Enhanced DbDataReader.GetSchemaTable() functionality returns catalog, namespace and detailed schema information even for complex queries.</li> <li>Named and unnamed parameters.</li> <li>Full UTF-8 and UTF-16 support.</li> <li>Multiple simultaneous DataReaders (one DataReader per Command however).</li> <li>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.</li> <li>Full support for user-defined collating sequences, every bit as simple to implement as user-defined functions and uses the same base class.</li></ul> <strong></strong> <h2> <strong>Compiling:</strong></h2> In order to use the SQLiteFactory and have the SQLite data provider enumerated in the DbProviderFactories methods, you must add the following segment into either your application's app.config or the system's machine.config located in the %SystemRoot%\Microsoft.Net\Framework\v2.xxxx\Config folder:<br /> <br /> <pre> <configuration> <system.data> <DbProviderFactories> <add name="SQLite Data Provider" invariant="System.Data.SQLite" support="3F" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /> </DbProviderFactories> </system.data> </configuration> </pre> <br /> <h3> Compiling for Beta 1:</h3> The <strong>System.Data.SQLite</strong> project was compiled using the November/December/February CTP's of Visual Studio 2005, but it can be compiled with some trivial effort on the previous Beta 1 edition of VS2005. Just right-click the <strong>System.Data.SQLite</strong> project, select <strong>Properties</strong>, go to the <strong>Build</strong> tab, and add <strong>BETA1</strong> to the conditional compilation symbols.<br /> <br /> <h3> Compiling for the Compact Framework</h3> <p> The SQLite.Interop.DLL does not (yet) support a build that includes Windows CE processor architectures. I am aware of the CE port of SQLite and will be investigating their code to see how best to proceed in that regard. I am also waiting for the newer version of SQLite to become available which will offer select metadata information and will cause a major redesign of this library to support it.<br /> <b> </b> </p> <h2> <b>Development Notes Regarding the SQLite 3 Source Code</b></h2> <p></p> <p> Steps for merging the sqlite3 core codebase:</p> <ol> <li>Download the latest sqlite3 source from <a href="http://www.sqlite.org/download.html"> http://www.sqlite.org/download.html</a></li> <li>Extract the source code to the <b>SQLite.Interop\src</b> directory of this project</li> <li>Open the <b>src\select.c</b> file.</li> <li>Add <b>#include "../interop.h" </b>to the top of the file where the other include's are.</li> <li>Scroll down the <b>select.c</b> file to around line <b>748</b>. Change the name of the function <b>static void generateColumnNames </b>to <b>static void _generateColumnNames</b> (<i>note the underscore in front of the name</i>).</li> <li>Compile it.</li> </ol> <b> </b> <h2> <b>Version History</b></h2> <b>1.08 - Mar 11, 2005<br /> </b> <ul> <li>Added additional #if statements to support the old beta 1 edition of VS2005.</li> <li>Code merged the SQLite 3.14 source.</li> </ul> <b>1.07 - Mar 5, 2005</b><br /> <ul> <li>Made more optimizations to frequently-called functions, resulting in significant performance gains in all tests. </li> <li> 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.</LI></UL><p> <b> 1.06 - Mar 1, 2005<br /> </b> </p> <ul> <li>Speed-ups to SQLiteDataReader. It was interop'ing unnecessarily every time it tried to fetch a field due to a logic error.</li> <li>Changed/Added some code to SQLiteConvert's internal DbType, Type and TypeAffinity functions.</li> <li>Fixed the SQLiteDataReader to obey the flags set in the optional CommandBehavior flag from SQLiteCommand.ExecuteReader().</li> <li>Changed the default page size to 1024 to reflect the defaults of SQLite.
