Mysql基礎存儲過程

#查詢表 user
select * from user

#刪除seleUser()存儲過程
drop procedure if exists seleUser;

**#查詢全部**
create procedure seleUser()
begin
		select * from `user`;
end;;
call seleUser();


#刪除seleUserId()
drop procedure if exists seleUserId;
**#根據id查詢**
create procedure seleUserId(in id INTEGER)
begin
		select * from `user` where uid = id;
end;;
call seleUserId(1);


drop procedure if exists login;
**#判斷是否存在 返回count(*)**
create procedure login(in NewAccount varchar(50),in NewPwd varchar(50))
begin
		select count(*) from `user` where account = NewAccount and pwd = NewPwd;
end;;
call login('404','123');

#刪除addUser()存儲過程
drop procedure if exists addUser;
**#新增**
create procedure addUser(in NewUname varchar(50),in NewAccount varchar(50),in NewPwd varchar(50),in NewSex char(2))
begin
		insert into user(uname,account,pwd,sex)value(NewUname,NewAccount,NewPwd,NewSex);
end;;
call addUser('王五','wangW','111','女');



drop procedure if exists deleIdUser;
**#根據id刪除**
create procedure deleIdUser(in NewUid INTEGER)
begin
	DELETE from user where uid = NewUid;
end;;
call deleIdUser(2);


drop procedure if exists uptIdUser;
**#根據id修改**
create procedure uptIdUser(in NewUid int,in NewUname varchar(50),in NewAccount varchar(50),in NewPwd varchar(50),in NewSex char(2))
begin
	UPDATE user set uname=NewUname,account=NewAccount,pwd=NewPwd,sex=NewSex  where uid = NewUid;
end;;
call uptIdUser(3,'小花','Xhua','123456','女');
