mysql更改语句的正确写法

[SQL] update case_history set ID=1,petID=2,doctorID=10,condition='gaga',med_date='wewe' where ID=1

[Err] 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 'condition='gaga',med_date='wewe' where ID=1' at line 1
这是我的错误，怎么改
