PDOStatement->errorCode — Fetch the SQLSTATE associated with the last operation on the statement handle
Identical to PDO::errorCode(), except that PDOStatement::errorCode() only retrieves error codes for operations performed with PDOStatement objects.
Beispiel #1 Retrieving an SQLSTATE code
<?php
/* Provoke an error -- the BONES table does not exist */
$err = $dbh->prepare('SELECT skull FROM bones');
$err->execute();
echo "\nPDOStatement::errorCode(): ";
print $err->errorCode();
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
PDOStatement::errorCode(): 42S02
Neither this property nor the PDOStatement::errorInfo() properties are available if you create your own exception handler.
I am using PHP 5.2.4, PDO_INFORMIX 1.2.0.
Making this call at any point in the program after setting your own exception handler produces an error:
PHP Notice: Undefined property: PDOStatement::$errorCode in new_query.php on line
or
PHP Notice: Undefined property: PDOStatement::$errorInfo in new_query.php on line
But if I set the PDO to SILENT, only set error codes with:
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_SILENT)
Then process with if/else the call to this functions works fine. The examples below only do error checking to show the result codes of this function. Normally you would want more.
FAILS:
$dbh = new PDO("informix...")
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try {
$result = $dbh->query("asdfkjasdfkjasdfjk"); /* obvious sql error */
if ($result) print "success!";
}
catch
{
$myeCode = $dbh->errorCode();
/* do stuff with error */
};
$dbh=0;
The error handler gets called but knows nothing about $dbh->errorCode or $dbh->errorInfo.
WORKS:
$dbh = new PDO("informix...")
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_SILENT);
$result = $dbh->query("asdfkjasdfkjasdfjk"); /* obvious sql error */
if ($result)
{
/* process result */
print "success!";
/* all done, didn't make any changes */
$dbh->rollback();
}
else
{
$myeCode = $dbh->errorCode();
print_r($myeCode);
};
$dbh=0; /* close connection */
I hope this helps someone else.
Cheers,
David
Statement's errorCode() returns an empty string before execution, and '00000' (five zeros) after a sucessfull execution:
<?php
$stmt = $pdo->prepare($query);
assert($stmt->errorCode === '');
$stmt->execute();
assert($stmt->errorCode === '00000');
?>
