1、如果用户有create routine 权限那么他就可以创建procedure | function 。

2、如果用户创建了procedure | function 那么mysql 会自动赋予它对procedure | function 的alter routine和execute 权限。

3、例子：

用户root用户创建一个spuser@'localhost'用户并对它赋予create routine 权限

grant create routine on tempdb.* to spuser@'localhost' identified by '123456';

用spuser@'localhost'用户去创建一个procedure

delimiter go
create procedure sp_hello_world()
begin
    select 'hello world';
delimiter ;

再一次查看spuser@'localhost'的权限

mysql> show grants;

| GRANT EXECUTE, ALTER ROUTINE ON PROCEDURE `tempdb`.`sp_hello_world` TO 'spuser'@'localhost'                   |
