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 $err->errorCode();
?>上の例の出力は以下となります。
PDOStatement::errorCode(): 42S02
Statement's errorCode() returns an empty string before execution, and '00000' (five zeros) after a sucessfull execution:<?php$stmt = $pdo->prepare($query);assert($stmt->errorCode === '');$stmt->execute();assert($stmt->errorCode === '00000');?>Neither this property nor the PDOStatement::errorInfo() properties are available if you create your own exception handler.I am using PHP 5.2.4, PDO_INFORMIX 1.2.0.Making this call at any point in the program after setting your own exception handler produces an error:PHP Notice: Undefined property: PDOStatement::$errorCode in new_query.php on lineorPHP Notice: Undefined property: PDOStatement::$errorInfo in new_query.php on lineBut if I set the PDO to SILENT, only set error codes with:$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
