<function>PDO::errorInfo</function> 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>
</row>

</tgroup>
</informaltable>
</para>
<para>
<function>PDO::errorInfo</function> only retrieves error information
for operations performed directly on the database handle. If you create
a PDOStatement object through <function>PDO::prepare</function> or
<function>PDO::query</function> and invoke an error on the statement
handle, <function>PDO::errorInfo</function> will insert an error code
of <literal>PDO_ERR_NONE</literal> into the first element of the returned
array. You must call <function>PDOStatement::errorInfo</function> to
return the error information for an operation performed on a particular
statement handle.
