Question

我试图将一个字段从一个表移动到另一个表，然后将其从第一个表中删除。我遇到的问题是，它可以很好地移动数据，但不能从第一张表中删除它。

这是我的代码：

"INSERT INTO out_tickets SELECT * FROM tickets";
        "DELETE FROM tickets WHERE * FROM tickets";

不确定我在做什么错吗？

更新代码：

<?php
// Process delete operation after confirmation
if(isset($_POST["id"]) && !empty($_POST["id"])){
// Include config file
require_once 'config.php';

// Prepare a select statement
$sql = "INSERT INTO out_tickets SELECT * FROM tickets";
        "DELETE FROM tickets";

if($stmt = mysqli_prepare($link, $sql)){
    // Bind variables to the prepared statement as parameters
    mysqli_stmt_bind_param($stmt, "i", $param_id);

    // Set parameters
    $param_id = trim($_POST["id"]);

    // Attempt to execute the prepared statement
    if(mysqli_stmt_execute($stmt)){
        // Records deleted successfully. Redirect to landing page
        header("location: technical.php");
        exit();
    } else{
        echo "Oops! Something went wrong. Please try again later.";
    }
}

据我了解，您尝试将 ALL 列从一个表（t1）移至结构相同的另一个表（t2）（或移至包含第一个相同列的表），是否要从已移至t2的table1中删除数据？如果正确，请使用下一个SQL

INSERT INTO t2 SELECT * FROM t1;
DELETE FROM t1 WHERE 1;
