$deleteUser = $_POST['userId'];
$query = "DELETE FROM users AS USERS
LEFT JOIN posts AS POSTS
ON USERS.id = POSTS.postAuthor
WHERE USERS.id = '$deleteUser' AND POSTS.postAuthor = '$deleteUser'";
我正在尝试删除该用户以及他们可能创建的任何帖子。我错过了什么？
最佳答案
指定执行DELETE的表或别名
DELETE USERS FROM users AS USERS
LEFT JOIN posts AS POSTS
ON USERS.id = POSTS.postAuthor
WHERE USERS.id = '$deleteUser' AND POSTS.postAuthor = '$deleteUser'
