ST页面的一个错误

错误提示如：

Database error: Invalid SQL: SELECT UserID, WeekClick FROM `UserClick` WHERE UserID NOT IN() ORDER BY WeekClick DESC LIMIT 0, 300 MySQL Error: 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 ') ORDER BY WeekClick DESC LIMIT 0, 300' at line 1) Session halted.

 

关键SQL语句为：

SELECT UserID, WeekClick FROM `UserClick` WHERE UserID NOT IN() ORDER BY WeekClick DESC LIMIT 0, 300
