<p>The first argument to the callback is just a copy of the fourth argument
to <b>sqlite_exec()</b> This parameter can be used to pass arbitrary
information through to the callback function from client code.
The second argument is the number columns in the query result.
The third argument is an array of pointers to strings where each string
is a single column of the result for that record. Note that the
callback function reports a NULL value in the database as a NULL pointer,
which is very different from an empty string. If the i-th parameter
is an empty string, we will get:</p>
<blockquote><pre>
argv[i][0] == 0
</pre></blockquote>
<p>But if the i-th parameter is NULL we will get:</p>
<blockquote><pre>
argv[i] == 0

<h2>News</h2>
<p>
Though still relatively new,
the SQLite code base appears to be working well and has therefore
been upgraded to "beta" status.
There are currently no known errors in the code.
One very large database (1M+ records in 50+ separate tables) has
been converted from PostgreSQL and gives every appearance of working
correctly.</p>
<p>Your constructive comments are still very important to us.
Please visit the
<a href="#mailinglist">mailing list</a> to offer feedback.</p>

<p>SQLite is intended to be small and light-weight.
It does not try to implement every feature of SQL.
A few of the many SQL features that SQLite does not (currently)
implement are as follows:</p>
<p>
<ul>
<li>The GROUP BY or HAVING clauses of a SELECT</li>
<li>Constraints</li>
<li>Nested queries</li>
<li>Transactions or rollback</li>
</ul>
</p>
<H2>Status</h2>
<p>The SQLite code is rapidly stablizing. There are currently
no known errors in the code. At least one large database has
be loaded into SQLite and appears to work. Most of the major
functionality is in place.</p>
<p>SQLite has so far been tested only on RedHat 6.0 Linux. But we
know of no reason why it will not work on any other Unix platform,
or on Windows95/98/NT.</p>

<h2>News</h2>
<p>
The SQLite code base is being called "beta" only because it is
relatively new. It appears to be stable and usable.
Most of the SQL language is now implemented and working.
The regression test suite
provides good coverage, according to
<a href="http://gcc.gnu.org/onlinedocs/gcov_1.html">gcov</a>.
There are currently no known errors in the code.</p>
<p>If you find bugs or missing features, please submit a comment
to the <a href="#mailinglist">SQLite mailing list</a>.</p>

<p>A history of changes to SQLite is found

<p>SQLite now implements most of the SQL language.
The following are the known limitations:</p>
<p>
<ul>
<li>The UNION, INTERSECTION and EXCEPT operations connecting multiple
SELECT statements are not yet implement</li>
<li>Constraints are parsed but are not enforced</li>
<li>There is not support for transactions or rollback</li>
</ul>
</p>
<H2>Status</h2>
<p>New features are still being added to the SQLite code base.
Nevertheless, the code appears to be stable and relatively
bug-free. At least one large database has
be loaded into SQLite and appears to work.</p>
<p>SQLite has so far been tested only on RedHat 6.0 Linux. But we
