ERROR 1064 (42000) Delete statement in RDS

Question

I tried to use RDS MySQL to store my data. This statement works in my local DB.

DELETE FROM movie_recommend mr WHERE mr.user_id = 71

But it's not executed in RDS MySQL.

ERROR 1064 (42000): 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 'mr where mr.user_id = 71' at line 1

Any helps what's wrong with the syntax?
