<b>PDO::errorInfo()</b> only retrieves error information for
operations performed directly on the database handle. If you create a
PDOStatement object through <a href="pdo.prepare.php" class="function">PDO::prepare()</a> or
<a href="pdo.query.php" class="function">PDO::query()</a> and invoke an error on the statement
handle, <b>PDO::errorInfo()</b> will not reflect the error
from the statement handle. You must call
<a href="pdostatement.errorinfo.php" class="function">PDOStatement::errorInfo()</a> to return the error
information for an operation performed on a particular statement handle.
