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');
?>
(PHP 5 >= 5.1.0, PHP 7, PHP 8, PECL pdo >= 0.1.0)
PDOStatement::errorCode — 文ハンドラにおける直近の操作に関連する SQLSTATE を取得する
この関数にはパラメータはありません。
PDOStatement::errorCode() は PDOStatement オブジェクトを用いて実行された操作に対する エラーコードを取得することを除き、 PDO::errorCode() と等価です。
例1 SQLSTATE コードを取得する
<?php
/* エラーを発生させる -- BONES テーブルは存在しない */
$err = $dbh->prepare('SELECT skull FROM bones');
$err->execute();
echo "\nPDOStatement::errorCode(): ";
print $err->errorCode();
?>上の例の出力は以下となります。
PDOStatement::errorCode(): 42S02
Statement's errorCode() returns an empty string before execution, and '00000' (five zeros) after a sucessfull execution:

?>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
