CREATE PROCEDURE insert_Sp
       @username varchar(50),
       @password varchar(50)
AS
begin
insert into login(username,password) values(@username,@password)

end


Select_Sp


CREATE PROCEDURE select_Sp
       @username varchar(50),
       @password varchar(50)
AS
begin
       SELECT username,password from login where username=@username and password =@password
end


Edit_Sp


CREATE PROCEDURE edit_Sp
       @password varchar(100),
       @Id int
AS
begin
       Update login set password=@password where Id=@Id
       end


Delete_Sp


CREATE PROCEDURE delete_Sp
       @Id int
AS
begin
       delete from login where Id=@Id
end
