這個函數是實驗性質的。這個函數的行為、名稱、和關於此函數的任何其他文件在未來PHP的發行中可能會在不通知的情況下改變。 使用此延伸需自行承擔風險。 |
Returns a SQLSTATE, a five-character alphanumeric identifier defined in the ANSI SQL standard.
PDO::errorCode() only retrieves error codes for operations performed directly on the database handle. If you create a PDOStatement object through PDO::prepare() or PDO::query() and invoke an error on the statement handle, PDO::errorCode() will return PDO_ERR_NONE. You must call PDOStatement::errorCode() to return the error code for an operation performed on a particular statement handle.
