php关于数据库修改删除问题
在php中利用MYSQL数据库对发帖进行删除修改的操作,该怎样做啊,求答,谢谢

------解决方案--------------------
一般都是读出帖子的id,然后再根据传入删除操作页面的帖子id参数来删除帖子。
------解决方案--------------------
用三个sql语句完成

INSERT INTO `te` (`1`, `2`, `3`, `4`, `5`) VALUES ('1', '2', '3', '4', '5');
UPDATE `te` SET `2`='x', `3`='x', `4`='x' WHERE `1`='1' AND `2`='2' AND `3`='3' AND `4`='4' AND `5`='5' LIMIT 1;
DELETE FROM `te` WHERE `1`='1' AND `2`='x' AND `3`='x' AND `4`='x' AND `5`='5' LIMIT 1;
