PHP-Handbuch: Fetch extended error information associated with the last operation on the database handle

Beschreibung

public array PDO::errorInfo ( void )

Rückgabewerte

PDO::errorInfo returns an array of error information about the last operation performed by this database handle. The array consists of the following fields:

Element	Information
0	SQLSTATE error code (a five characters alphanumeric identifier defined in the ANSI SQL standard).
1	Driver-specific error code.
2	Driver-specific error message.

Hinweis:
If the SQLSTATE error code is not set or there is no driver-specific error, the elements following element 0 will be set to NULL.

PDO::errorInfo only retrieves error information for operations performed directly on the database handle. If you create a PDOStatement object through PDO::prepare or PDO::query and invoke an error on the statement handle, PDO::errorInfo will not reflect the error from the statement handle. You must call PDOStatement::errorInfo to return the error information for an operation performed on a particular statement handle.

Beispiele

Beispiel #1 Displaying errorInfo() fields for a PDO_ODBC connection to a DB2 database


<?php
/* Provoke an error -- bogus SQL syntax */
$stmt = $dbh->prepare('bogus sql');
if (!$stmt) {
    echo "\nPDO::errorInfo():\n";
    print_r($dbh->errorInfo());
}
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

PDO::errorInfo():
Array
(
    [0] => HY000
    [1] => 1
    [2] => near "bogus": syntax error
)
