Question

我正在尝试mysqli_multi_query。出于某种原因，它不会起作用。以下是我到目前为止所做的事情：

<?php
$con=mysqli_connect("host","user","pw","db");

if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

   $orderid = $_GET['orderid'];
   $sql = "INSERT INTO orders_archive SELECT * FROM orders WHERE orders_id='".$orderid."'";
   $sql .= "DELETE FROM orders WHERE orders_id='".$orderid."'";


mysqli_multi_query($con,$sql);

mysqli_close($con);
?>

orderid由ajax授予。

Answer 1

查询必须用;分隔。

$sql = "INSERT INTO orders_archive SELECT * FROM orders WHERE orders_id='".$orderid."';";
$sql .= "DELETE FROM orders WHERE orders_id='".$orderid."'";

Answer 2

您需要在查询末尾添加semicolun才能将其分隔

 $sql = "INSERT INTO orders_archive SELECT * FROM orders WHERE orders_id='".$orderid."';";
 $sql .= "DELETE FROM orders WHERE orders_id='".$orderid."'";

mysqli_multi_query无效，没有任何反应
