This time string may be followed by zero or more modifiers. The <b>strftime()</b> function also takes a format string as its first argument. <p>The <b>date()</b> function returns the date in this format: YYYY-MM-DD. The <b>time()</b> function returns the time as HH:MM:SS. The <b>datetime()</b> function returns "YYYY-MM-DD HH:MM:SS". The <b>julianday()</b> function returns the number of days since noon in Greenwich on November 24, 4714 B.C. The julian day number is the preferred internal representation of dates. The <b>strftime()</b> routine returns the date formatted according to the format string specified as the first argument. The format string supports most, but not all, of the more common substitutions found in the strftime() function from the standard C library: <p><pre> %d day of month %f ** fractional seconds SS.SSS %H hour 00-24 %j day of year 001-366 %J ** Julian day number %m month 01-12 %M minute 00-59 %s seconds since 1970-01-01 %S seconds 00-59 %w day of week 0-6 sunday==0 %W week of year 00-53 %Y year 0000-9999 %% % </pre> <p>The %f and %J conversions are new. Notice that all of the other four functions could be expressed in terms of <b>strftime()</b>. <p><pre> date(...) -> strftime("%Y-%m-%d", ...) time(...) -> strftime("%H:%M:%S", ...) datetime(...) -> strftime("%Y-%m-%d %H:%M:%S", ...) julianday(...) -> strftime("%J", ...) </pre> <p>The only reasons for providing functions other than <b>strftime()</b> is for convenience and for efficiency. <p><b>Time Strings</b> <p>A time string can be in any of the following formats: <p><ol> <li>YYYY-MM-DD <li>YYYY-MM-DD HH:MM <li>YYYY-MM-DD HH:MM:SS <li>YYYY-MM-DD HH:MM:SS.SSS <li>YYYY-MM-DDTHH:MM <li>YYYY-MM-DDTHH:MM:SS <li>YYYY-MM-DDTHH:MM:SS.SSS <li>HH:MM <li>HH:MM:SS <li>HH:MM:SS.SSS <li>now <li>DDDD.DDDD </ol> <p>In formats 5 through 7, the "T" is a literal character separating the date and the time, as required by the ISO-8601 standard. These formats are supported in SQLite 3.2.0 and later. Formats 8 through 10 that specify only a time assume a date of 2000-01-01. Format 11, the string 'now', is converted into the current date and time. Universal Coordinated Time (UTC) is used. Format 12 is the julian day number expressed as a floating point value. <p><b>Modifiers</b> <p>The time string can be followed by zero or more modifiers that alter the date or alter the interpretation of the date. The available modifiers are as follows. <p><ol> <li>NNN days <li>NNN hours <li>NNN minutes <li>NNN.NNNN seconds <li>NNN months (see <a href="tktview?tn=551">#551</a> and <a href="chngview?cn=1163">[1163]</a> ) <li>NNN years (see <a href="tktview?tn=551">#551</a> and <a href="chngview?cn=1163">[1163]</a> ) <li>start of month <li>start of year <li>start of week (withdrawn -- will not be implemented) <li>start of day <li>weekday N (see <a href="tktview?tn=551">#551</a> and <a href="chngview?cn=1163">[1163]</a> ) <li>unixepoch <li>localtime <li>utc </ol> <p>The first six modifiers (1 through 6) simply add the specified amount of time to the date specified by the preceding timestring. <p>The "start of" modifiers (7 through 10) shift the date backwards to the beginning of the current month, year or day. <p>The "weekday" modifier advances the date forward to the next date where the weekday number is N. Sunday is 0, Monday is 1, and so forth. <p>The "unixepoch" modifier (12) only works if it immediately follows a timestring in the DDDDDDDDDD format. This modifier causes the DDDDDDDDDD to be interpreted not as a julian day number as it normally would be, but as the number of seconds since 1970. This modifier allows unix-based times to be converted to julian day numbers easily. <p>The "localtime" modifier (13) adjusts the previous time string so that it displays the correct local time. "utc" undoes this. <p><b>Examples</b> <p>Compute the current date. <p><pre> SELECT date('now'); </pre> <p>Compute the last day of the current month. <p><pre> SELECT date('now','start of month','+1 month','-1 day'); </pre> <p>Compute the date and time given a unix timestamp 1092941466. <p><pre> SELECT datetime(1092941466, 'unixepoch'); </pre> <p>Compute the date and time given a unix timestamp 1092941466, and compensate for your local timezone. <p><pre> SELECT datetime(1092941466, 'unixepoch', 'localtime'); </pre> <p>Compute the current unix timestamp. <p><pre> SELECT strftime('%s','now'); </pre> <p>Compute the number of days since the battle of Hastings. <p><pre> SELECT julianday('now') - julianday('1066-10-14','gregorian'); </pre> <p>Compute the number of seconds between two dates: <p><pre> SELECT julianday('now')*86400 - julianday('2004-01-01 02:34:56')*86400; </pre> <p>Compute the date of the first Tuesday in October (January + 9) for the current year. <p><pre> SELECT date('now','start of year','+9 months','weekday 2'); </pre> <p><b>Caveats And Bugs</b> <p>The computation of local time depends heavily on the whim of local politicians and is thus difficult to get correct for all locales. In this implementation, the standard C library function localtime() is used to assist in the calculation of local time. Note that localtime() is not threadsafe, so use of the "localtime" modifier is not threadsafe. Also, the localtime() C function normally only works for years between 1970 and 2037. For dates outside this range, SQLite attempts to map the year into an equivalent year within this range, do the calculation, then map the year back. <p><i>Please surround uses of localtime() with sqliteOsEnterMutex() and sqliteOsLeaveMutex() so threads using SQLite are protected, at least! -- e</i> It is so. --drh <p><i>[Consider instead, using localtime_r which is reentrant and may be used *without* expensive mutex locking. Although non-standard it's available on most Unixes --hauk]</i> But it is not available on windows, as far as I am aware. --drh On windows localtime() is thread-safe if the MT C runtime is used. The MT runtime uses thread-local storage for the static variables, the kind functions use.--gr <i>[What about using localtime_r, and on systems where it is unavailable defining it as sqliteOsEnterMutext() ; locatime() ; sqliteOsLeaveMutex() so that non-windows systems get the maximum advantage, with almost zero code impact?]</i> The autoconfigury and patch for localtime_r is here: <font color="#a0a0a0">¤</font><a href="http://www.sqlite.org/cvstrac/tktview?tn=1906">http://www.sqlite.org/cvstrac/tktview?tn=1906</a> .

................................................................................
This section is different from the others. Most other sections of this document
talks about a particular SQL command. This section does not talk about a standalone
command but about "expressions" which are subcomponents of most other commands.</p>
<p>
SQLite understands the following binary operators, in order from highest to lowest
precedence:</p>
<blockquote>
<pre>
<font color="#2c2cf0"><big>|| * / % + - << >> & | < <= >
>= = == != <> </big>IN AND OR</font>
</pre>
</blockquote>
<p>
Supported unary operators are these:</p>
<blockquote>
<pre>
<font color="#2c2cf0"><big>- + ! ~ NOT</big></font>
</pre>
</blockquote>
<p>
The unary operator [Operator +] is a no-op. It can be applied to strings, numbers,
or blobs and it always gives as its result the value of the operand.</p>
<p>
Note that there are two variations of the equals and not equals operators. Equals
................................................................................
would result in syntactic ambiguity. A string constant is formed by enclosing the
string in single quotes ('). A single quote within the string can be encoded by
putting two single quotes in a row - as in Pascal. C-style escapes using the backslash
character are not supported because they are not standard SQL. BLOB literals are
string literals containing hexadecimal data and preceded by a single "x" or "X"
character. For example:</p>
<blockquote>
<pre>
X'53514697465'
</pre>
</blockquote>
<p>
A literal value can also be the token "NULL".
</p>
<p>
A parameter specifies a placeholder in the expression for a literal value that is
filled in at runtime using the <a href="capi3ref.html#sqlite3_bind_int">sqlite3_bind</a>
API. Parameters can take several forms:
</p>

................................................................................
This section is different from the others. Most other sections of this document
talks about a particular SQL command. This section does not talk about a standalone
command but about "expressions" which are subcomponents of most other commands.</p>
<p>
SQLite understands the following binary operators, in order from highest to lowest
precedence:</p>
<blockquote>
<pre><font color="#2c2cf0"><big>|| * / % + - << >> & | < <= >
>= = == != <> </big>IN AND OR</font>
</pre>
</blockquote>
<p>
Supported unary operators are these:</p>
<blockquote>
<pre><font color="#2c2cf0"><big>- + ! ~ NOT</big></font>
</pre>
</blockquote>
<p>
The unary operator [Operator +] is a no-op. It can be applied to strings, numbers,
or blobs and it always gives as its result the value of the operand.</p>
<p>
Note that there are two variations of the equals and not equals operators. Equals
................................................................................
would result in syntactic ambiguity. A string constant is formed by enclosing the
string in single quotes ('). A single quote within the string can be encoded by
putting two single quotes in a row - as in Pascal. C-style escapes using the backslash
character are not supported because they are not standard SQL. BLOB literals are
string literals containing hexadecimal data and preceded by a single "x" or "X"
character. For example:</p>
<blockquote>
<pre>X'53514697465'
</pre>
</blockquote>
<p>
A literal value can also be the token "NULL".
</p>
<p>
A parameter specifies a placeholder in the expression for a literal value that is
filled in at runtime using the <a href="capi3ref.html#sqlite3_bind_int">sqlite3_bind</a>
API. Parameters can take several forms:
</p>

<p><b>1.0.35.0 - September 10, 2006</b></p>
<ul>
<li>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. </li><li>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.</li>
<li>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.</li>

The SQLite3 source code is compiled directly from the SQLite.org release
sources. All builds of sqlite after 3.2.8 have included support for Windows CE. Additionally,
just one minor modification is made to pager.c, that modification is made automatically by the fixsource.vbs file

<b>Version History</b></p>
<p><b>1.0.35.0 - September 10, 2006</b></p>
<ul>
<li>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. </li><li>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.</li>
