mysql存储过程重命名修改错误

navicat环境下
按照数据库课本上使用代码
ALTER PROCEDURE stuinfo rename to stu_info

结果报错了

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 'rename to stu_info' at line 1, Time: 0.000000s

rename语法好像不是这样用的
