注册

向T_users 插入一条用户写好的信息

use UserDB1

seclect * from T_users

Create proc usp_Registor

@name varchar(50),

@pwd varchar(50),

@email varchar(50)

as begin

insert into T_users(FuserName,Fpassword,Femail) values(@name,@password,@email)

end

exec usp_Registor'白白','111','bai@126.com'

---------删除存储过程删除特定表中的一条记录

use School

select * from Class

create proc usp_Student_Delete

as begin

delete from Student where sId=@sId

end

exec usp_Student_Delete @sId=14

--------------修改特定表中的某条记录（更新操作）

select * from Class

create proc usp_Class_update

@Cid int,

@Cname varchar(50),

@CDes varchar(50)

as begin

upate Class set cName=@Cname,cDescription=@CDes where
clsId=@Cid

end

exec usp_Class_update 10,'3G','优秀班集体'

----------------查询所有记录

create proc usp_Class_SelectAll

as

begin

select * from Class

end

exec usp_Class_SelectAll

------------针对特定表分页的存储过程

create proc usp_MyStudent_GetDateByPageIndex

@pageSize int=10, //默认每页10 条

@pageIndex int

as

begin

select * from

(select *,Row_Number() over(order by Fid) as rowIndex from MyStudent)

as tbl

where tb1.rowIndex between (@pageSize*(@pageIndex-1)+1)and @pageSize*@pageIndex

end
