从mysql表中删除WHERE列等于值AND列2等于value2

Question

在使此查询正常工作时遇到一些麻烦.

mysql_query("DELETE FROM `table` WHERE `id` = '$id' AND 'username' = '$username' ");

尝试用实际数据替换变量并在phpmyadmin中运行它没有成功

有什么想法吗？

Answer 1

您使用'而不是`来引用用户名列

使用:

mysql_query("DELETE FROM `table` WHERE `id` = '$id' AND `username` = '$username'");

不:

mysql_query("DELETE FROM `table` WHERE `id` = '$id' AND 'username' = '$username'");
