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

    public PDOStatement::errorCode(): ?string

    参数

    此函数没有参数。

    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。

    示例

    示例 #1 检索 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();
    ?>

    以上示例会输出：

    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 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
