<a href="http://www.gnu.org/software/gdbm/gdbm.html">GDBM</a></h1>
<p align=center>}
................................................................................
three functions and one opaque structure.</li>
<li>A <a href="tclsqlite.html">Tcl</a> interface is
included.</li>
<li>Command-line access program <a href="sqlite.html">sqlite</a> uses
the <a href="http://www.google.com/search?q=gnu+readline+library">GNU
Readline library</a></li>
<li>A Tcl-based test suite provides near 100% code coverage</li>
<li>7500+ lines of C code.  No external dependencies other than GDBM.</li>

<li>Built and tested under Linux, HPUX, and WinNT.</li>
</ul>
</p>

<h2>Current Status</h2>

<p>A <a href="changes.html">change history</a> is available online.
................................................................................
There are currently no <em>known</em> bugs or memory leaks
in the library.  <a href="http://gcc.gnu.org/onlinedocs/gcov_1.html">Gcov</a>
is used to verify test coverage.  The test suite currently exercises
all code except for a few areas which are unreachable or which are
only reached when <tt>malloc()</tt> fails.  The code has been tested
for memory leaks and is found to be clean.</p>

<p><b>Important Note:</b>  A bug was found in the processing of UPDATE
statements when the WHERE clause contained some terms that could be 
satisfied using indices and other terms which could not.  The problem
was fixed in version 1.0.22.  Users of prior versions of SQLite should
consider upgrading.</p>


<p>
Among the SQL features that SQLite does not currently implement are:</p>


<p>
<ul>
<li>constraints are parsed but are not enforced</li>
</ul>
</p>

<h2>Documentation</h2>

<p>The following documentation is currently available:</p>

three functions and one opaque structure.</li>
<li>A <a href="tclsqlite.html">Tcl</a> interface is
included.</li>
<li>Command-line access program <a href="sqlite.html">sqlite</a> uses
the <a href="http://www.google.com/search?q=gnu+readline+library">GNU
Readline library</a></li>
<li>A Tcl-based test suite provides near 100% code coverage</li>
<li>Approximately 9500 lines of C code.  No external dependencies other 
than GDBM.</li>
<li>Built and tested under Linux, HPUX, and WinNT.</li>
</ul>
</p>

<h2>Current Status</h2>

<p>A <a href="changes.html">change history</a> is available online.
................................................................................
There are currently no <em>known</em> bugs or memory leaks
in the library.  <a href="http://gcc.gnu.org/onlinedocs/gcov_1.html">Gcov</a>
is used to verify test coverage.  The test suite currently exercises
all code except for a few areas which are unreachable or which are
only reached when <tt>malloc()</tt> fails.  The code has been tested
for memory leaks and is found to be clean.</p>

<p><b>Important Note:</b>  Beginning with version 1.0.29, the LIKE and
GLOB operators assume both operands are UTF-8 strings.  Prior to that,
both operators assumed plain ASCII strings.  Users of earlier versions
of SQLite that invoke LIKE or GLOB to compare strings containing
characters greater than 127 may have problems when they upgrade to
version 1.0.29 or later.</p>


<p><b>Important Note:</b>  Serious bugs have been found in versions

1.0.22 on Unix and 1.0.26 on Windows.  Users of these or earlier
versions of SQLite should upgrade.</p>
