分页的存储过程的用法

数据库的存储

alter PROCEDURE Proc_stu
@PageIndex int, //页数
@PageSize int,//显示条数
@where nvarchar(50),//条件

@Tocount int output, //返回值

@totName nvarchar(50),//表名
@order nvarchar(50)//排序
AS
BEGIN

SET NOCOUNT ON;

-- Insert statements for procedure here
declare @sqlcount nvarchar(2000)='';
set @sqlcount+='select @Tocount=count(1) from '+@totName+' '+@where+' ';
exec sp_executesql @sqlcount,N'@Tocount int output',@Tocount output

declare @sqltable nvarchar(1000)='';
set @sqltable+='
select top('+cast(@PageSize as nvarchar(50))+') * from(
select row_number() over(order by '+@order+') as s,* from '+@totName+' where 1=1 '+@where+' ) a
where s>'+cast((@PageIndex-1)* @PageSize as nvarchar(50))
exec sp_executesql @sqltable
END

数据库的存储两个表

ALTER PROCEDURE [dbo].[Pro_page]
@pageindex INT=1,
@pagesize INT=2,
@Totcount INT OUTPUT,--总数
@totName NVARCHAR(50),--表名
@order NVARCHAR(50),--排序
@where NVARCHAR(50) --查询
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

-- Insert statements for procedure here
DECLARE @sqlcount NVARCHAR(2000)='';

SET @sqlcount+='SELECT @Totcount= COUNT(1) FROM ' +@totName+' '+@where+'';

EXEC sp_executesql @sqlcount,N'@Totcount INT OUTPUT',@Totcount OUTPUT

DECLARE @sqldata NVARCHAR(2000)='';

--两个表 直接写两表的查询名stu s INNER JOIN stutype p ON s.TypeID=p.TypeID
SET @sqldata+='SELECT TOP('+CAST(@pagesize AS NVARCHAR(100))+') * FROM
(SELECT ROW_NUMBER() OVER(ORDER BY '+@order+') AS rownum ,s.*,p.TypeName FROM

'+@totName+' where 1=1 ' +@where+') a WHERE a.rownum>'+CAST((@pageindex-1)*@pagesize AS nvarchar(50))
EXEC sp_executesql @sqldata
END
