<h2>SQLite Release 3.8.4.3 On 2014-04-03</h2><p><b>Changes in version 3.8.4 (2014-03-10):</b></p>
 | 
						|
<p><ol class='lessindent'>
 | 
						|
<li value='1'>Code optimization and refactoring for improved performance.
 | 
						|
<li>Add the ".clone" and ".save" commands to the command-line shell.
 | 
						|
<li>Update the banner on the command-line shell to alert novice users when they
 | 
						|
    are using an ephemeral in-memory database.
 | 
						|
<li>Fix editline support in the command-line shell.
 | 
						|
<li>Add support for coverage testing of VDBE programs using the
 | 
						|
    <a href="../c3ref/c_testctrl_always.html">SQLITE_TESTCTRL_VDBE_COVERAGE</a> verb of <a href="../c3ref/test_control.html">sqlite3_test_control()</a>.
 | 
						|
<li>Update the _FILE_OFFSET_BITS macro so that builds work again on QNX.
 | 
						|
<li>Change the datatype of SrcList.nSrc from type u8 to type int to work around 
 | 
						|
    an issue in the C compiler on AIX.
 | 
						|
<li>Get extension loading working on Cygwin.
 | 
						|
<li>Bug fix: Fix the <a href="../lang_corefunc.html#char">char()</a> SQL function so that it returns an empty string
 | 
						|
    rather than an "out of memory" error when called with zero arguments. 
 | 
						|
<li>Bug fix: DISTINCT now recognizes that a <a href="../lang_corefunc.html#zeroblob">zeroblob</a> and a blob of all
 | 
						|
    0x00 bytes are the same thing. 
 | 
						|
    <a href="http://www.sqlite.org/src/info/fccbde530a">Ticket [fccbde530a]</a>
 | 
						|
<li>Bug fix: Compute the correct answer for queries that contain an IS NOT NULL
 | 
						|
    term in the WHERE clause and also contain an OR term in the WHERE clause and
 | 
						|
    are compiled with <a href="../compile.html#enable_stat4">SQLITE_ENABLE_STAT4</a>.
 | 
						|
    <a href="http://www.sqlite.org/src/info/4c86b126f2">Ticket [4c86b126f2]</a>
 | 
						|
<li>Bug fix: Make sure "rowid" columns are correctly resolved in joins between
 | 
						|
    normal tables and WITHOUT ROWID tables.
 | 
						|
    <a href="http://www.sqlite.org/src/info/c34d0557f7">Ticket [c34d0557f7]</a>
 | 
						|
<li>Bug fix: Make sure the same temporary registers are not used in concurrent
 | 
						|
    co-routines used to implement compound SELECT statements containing ORDER
 | 
						|
    BY clauses, as such use can lead to incorrect answers.
 | 
						|
    <a href="http://www.sqlite.org/src/info/8c63ff0eca">Ticket [8c63ff0eca]</a>
 | 
						|
<li>Bug fix: Ensure that "ORDER BY random()" clauses do not get optimized out.
 | 
						|
    <a href="http://www.sqlite.org/src/info/65bdeb9739">Ticket [65bdeb9739]</a>
 | 
						|
<li>Bug fix: Repair a name-resolution error that can occur in sub-select statements
 | 
						|
    contained within a TRIGGER.
 | 
						|
    <a href="http://www.sqlite.org/src/info/4ef7e3cfca">Ticket [4ef7e3cfca]</a>
 | 
						|
<li>Bug fix: Fix column default values expressions of the form
 | 
						|
    "DEFAULT(-(-9223372036854775808))" so that they work correctly, initializing
 | 
						|
    the column to a floating point value approximately equal to
 | 
						|
    +9223372036854775808.0.
 |

 | 
						|
<li value='17'>Work around a C-preprocessor macro conflict that breaks the build for some
 | 
						|
    configurations with Microsoft Visual Studio.
 | 
						|
<li>When computing the cost of the <a href="../optoverview.html#skipscan">skip-scan optimization</a>, take into account the
 | 
						|
    fact that multiple seeks are required.

    for a problem that might cause incorrect query results on a query that mixes
 | 
						|
    DISTINCT, GROUP BY in a subquery, and ORDER BY.
