<span class="function"><strong>db2_conn_error()</strong></span> returns an SQLSTATE value representing
the reason the last attempt to connect to a database failed. As
<span class="function"><a href="function.db2-connect.html" class="function">db2_connect()</a></span> returns <strong><code>FALSE</code></strong> in the event of a failed
connection attempt, you do not pass any parameters to
<span class="function"><strong>db2_conn_error()</strong></span> to retrieve the SQLSTATE value.
</p>
<p class="para">
If, however, the connection was successful but becomes invalid over time,
you can pass the <em><code class="parameter">connection</code></em> parameter to retrieve
the SQLSTATE value for a specific connection.
</p>
<p class="para">
To learn what the SQLSTATE value means, you can issue the following command
at a DB2 Command Line Processor prompt:
<strong class="userinput"><code>db2 '? <em><code class="parameter">sqlstate-value</code></em>'</code></strong>. You
can also call <span class="function"><a href="function.db2-conn-errormsg.html" class="function">db2_conn_errormsg()</a></span> to retrieve an
explicit error message and the associated SQLCODE value.
