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 '';
用spuser@'localhost'用户去创建一个procedure
delimiter go
create procedure sp_hello_world()
begin
select 'hello world';
end
go delimiter ;
再一次查看spuser@'localhost'的权限
mysql> show grants;
+---------------------------------------------------------------------------------------------------------------+
| Grants for spuser@localhost |
+---------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'spuser'@'localhost' IDENTIFIED BY PASSWORD '*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9' |
| GRANT CREATE ROUTINE ON `tempdb`.* TO 'spuser'@'localhost' |
| GRANT EXECUTE, ALTER ROUTINE ON PROCEDURE `tempdb`.`sp_hello_world` TO 'spuser'@'localhost' |
