<code class="literal">dbsql</code> is a command line tool that provides access to the Berkeley DB
SQL interface.
</p>
<p>
To build this tool, run the configure script with the
<code class="literal">--enable-sql </code>option when you are building the
Berkeley DB SQL interface. For more information on building this tool,
see

</p>
<p>FILENAME is the name of a Berkeley DB database file created with the SQL interface. A new database is created
if the file does not exist.

The <code class="literal">dbsql</code> executable provides the same interface as the <code class="literal">sqlite3</code>
executable that is part of SQLite. For more information on how
to use dbsql see the
<a class="ulink" href="http://www.sqlite.org/sqlite.html" target="_top">SQLite Documentation page.</a>

</div>
<p>
This section describes pre-defined query statements that can be
executed from the <code class="literal">dbsql</code> command line. These queries take the form
of:
</p>
<pre class="programlisting"> .stat <span class="emphasis"><em>ITEM</em></span></pre>
<p>
where <code class="literal">ITEM</code> is an optional parameter that indicates
what statistics to print. If <code class="literal">ITEM</code> is not
specified, then this command prints statistics for the Berkeley DB
environment, followed by statistics for all tables and indexes
within the database.
</p>
<p>
If <code class="literal">ITEM</code> is the name of a table or index, then this
command prints statistics for the table or index using the
<a class="xref" href="dbstat_print.html" title="Db::stat_print()">Db::stat_print()</a>
method.
</p>
<p>
Otherwise, <code class="literal">ITEM</code> can be one of several keywords.
They are:
</p>
<div class="itemizedlist">
<ul type="disc">
<li>
<p>
<code class="literal">:env:</code>
</p>
<pre class="programlisting">dbsql> .stat :env:</pre>
<p>
Causes this command to print statistics for the Berkeley DB
environment using the
<a class="xref" href="envstat.html" title="DbEnv::stat_print()">DbEnv::stat_print()</a>.
method.
</p>
</li>
<li>
<p>
<code class="literal">:rep:</code>
</p>
<pre class="programlisting">dbsql> .stat :rep:</pre>
<p>
Causes this command to print a summary of replication
statistics.
