MySQLi - Sqlstate

语法

string mysqli_sqlstate ( mysqli $link )

定义和用法

从上一个 MySQL 操作中返回 SQLSTATE 错误。

示例

尝试以下示例 -

<?php
   $servername = "localhost:3306";
   $username = "root";
   $password = "";
   $dbname = "TUTORIALS";
   $conn = new mysqli($servername, $username, $password, $dbname);

   if ($conn->connect_error) {
      die('Connect Error (' . mysqli_connect_errno() . ') '. mysqli_connect_error());
      exit();
   } 
   if (!$conn->query("CREATE TABLE tutorials_point (ID INT, Name VARCHAR(30))")) {
      printf("Error - SQLSTATE %s.\n", $mysqli->sqlstate);
   }
?>

上述代码的示例输出应如下 -

Errorcode: 0 Success... localhost:3306 via TCP/IP Client library version:
