<xref linkend="function.PDO-errorInfo" /> returns an array of error information
about the last operation performed by this database handle. The array
consists of the following fields:
<informaltable>
<tgroup cols='2'>
<thead>
<row>
<entry>Element</entry>
<entry>Information</entry>
</row>
</thead>
<tbody>
<row>
<entry>0</entry>
<entry>SQLSTATE error code (a five-character alphanumeric identifier defined
in the ANSI SQL standard).</entry>

<entry>Driver-specific error code.</entry>
</row>
<row>
<entry>2</entry>
<entry>Driver-specific error message.</entry>

</tgroup>
</informaltable>
</para>
<para>
<xref linkend="function.PDO-errorInfo" /> only retrieves error information for
operations performed directly on the database handle. If you create a
PDOStatement object through <xref linkend="function.PDO-prepare" /> or
<xref linkend="function.PDO-query" /> and invoke an error on the statement
handle, <xref linkend="function.PDO-errorInfo" /> will not reflect the error
from the statement handle. You must call
<xref linkend="function.PDOStatement-errorInfo" /> to return the error
information for an operation performed on a particular statement handle.
