PDOStatement::errorCode

(PHP 5 >= 5.1.0, PHP 7, PHP 8, PECL pdo >= 0.1.0)

PDOStatement::errorCode — 获取跟上一次语句句柄操作相关的 SQLSTATE

说明

PDOStatement::errorCode ( ) : string

返回值

与 PDO::errorCode() 相同，只是 PDOStatement::errorCode() 只取回 PDOStatement 对象执行操作中的错误码。

范例

Example #1 取回一个 SQLSTATE 码


<?php
/* 引发一个错误 --  BONES 数据表不存在 */
$err = $dbh->prepare('SELECT skull FROM bones');
$err->execute();

echo "\nPDOStatement::errorCode(): ";
print $err->errorCode();
?>

以上例程会输出：

PDOStatement::errorCode(): 42S02

PDO::errorInfo() - Fetch extended error information associated with the last operation on the database handle

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');

?>
