<p>Each append call adds to an <code>ArrayList</code> buffer. When the buffer is filled each log event is placed in a sql statement (configurable) and executed.</p>
<p><b>BufferSize</b>, <b>db URL</b>, <b>User</b>, & <b>Password</b> are configurable options in the standard log4j ways.</p>
<p>The <code>setSql(String sql)</code> sets the SQL statement to be used for logging -- this statement is sent to a <code><a class="el" href="classlog4cxx_1_1_pattern_layout.html" title="A flexible layout configurable with pattern string.">PatternLayout</a></code> (either created automaticly by the appender or added by the user). Therefore by default all the conversion patterns in <code><a class="el" href="classlog4cxx_1_1_pattern_layout.html" title="A flexible layout configurable with pattern string.">PatternLayout</a></code> can be used inside of the statement. (see the test cases for examples)</p>
<p>Overriding the <a class="el" href="classlog4cxx_1_1db_1_1_o_d_b_c_appender.html#acdd1df6edd6df02a3a2fabdf197f2c5e">getLogStatement</a> method allows more explicit control of the statement used for logging.</p>
<p>For use as a base class:</p>
<ul>
<li>
<p class="startli">Override <a class="el" href="classlog4cxx_1_1db_1_1_o_d_b_c_appender.html#a08b7f6ae5633ed288db9806dac6b3482" title="Override this to link with your connection pooling system.">getConnection()</a> to pass any connection you want. Typically this is used to enable application wide connection pooling.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">Override closeConnection -- if you override getConnection make sure to implement <code>closeConnection</code> to handle the connection you generated. Typically this would return the connection to the pool it came from.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">Override getLogStatement to produce specialized or dynamic statements. The default uses the sql option value.</p>
<p class="endli"></p>
