php - MySql 查询 : DELETE FROM. 语法错误或访问冲突:1064

Question

foreach ($checkArray as $key => $value) {

    $deleteUserStmt=$user_home->runQuery("DELETE FROM users WHERE userID = '".$key."' " AND " '".$value."'=1");

$deleteUserStmt->execute();
}

出现错误:

Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '1' at line 1

$checkArray $key 是用户 ID，值是 true 或 false。 RunQuery 方法与其他查询一起使用。

所以我认为我的查询语法有问题？

Answer 1

查询应该像这样，不要为列名添加单引号:
“从 userID = '$key' AND $value='1' 的用户中删除”
