for the right syntax to use near ''X''问题解决

BUG:

Error Number: 1064

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''4'' at line 1

SELECT a.*,b.user_nickname, b.user_head_url from qk_user_album a, qk_user b where a.album_user_id = b.user_id ORDER BY a.album_create_date desc LIMIT 0, '4';

Line Number: 330

问题解决：

这里用到的是limit语法，两个参数应该都是数字，不应该出现字符串

查明的原因是PHP传递参数的时候，第二参数没有做转换，加一个intval函数，字符串转数字即可
