2月27日 常用存储过程

1.分页：

 

---存储过程、row_number完成分页
if (object_id('pro_page', 'P') is not null)
    drop proc proc_cursor
go
create proc pro_page
    @startIndex int,
    @endIndex int
as
    select count(*) from product
;    
    select * from (
        select row_number() over(order by pid) as rowId, * from product 
    ) temp
    where temp.rowId between @startIndex and @endIndex
go
--drop proc pro_page
exec pro_page 1, 4

--分页存储过程
if (object_id('pro_page', 'P') is not null)
    drop proc pro_stu
go
create procedure pro_stu(
    @pageIndex int,
    @pageSize int
)
as
    declare @startRow int, @endRow int
    set @startRow = (@pageIndex - 1) * @pageSize +1
    set @endRow = @startRow + @pageSize -1
    select * from (
        select *, row_number() over (order by id asc) as number from student 
    ) t
    where t.number between @startRow and @endRow;

exec pro_stu 2, 2;

2.删除表

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go


--        <><><><><><><><><><><><><>
--        <>                      <>
--        <>      类_删除表       <>
--        <>                      <>
--        <><><><><><><><><><><><><>


Create PROCEDURE [dbo].[类_删除表]


     @Sql_Table varchar(30) = 'temp_1'    -- 要删除的数据表名
As
BEGIN
	SET NOCOUNT ON;
 
    declare @Sql_Sql nvarchar(200)
    declare @uuu int
    set @uuu=0


	set @Sql_Sql='select @uuu=count(id) from sysobjects where id = object_id(N'+''''+'[dbo].['+@Sql_Table+']'+''''+') and OBJECTPROPERTY(id, N'+''''+'IsUserTable'+''''+') = 1'
    
    EXEC sp_executesql @Sql_Sql,N'@uuu int output',@uuu OUTPUT


    if @uuu>0
	exec('drop table '+@Sql_Table)


END
