sql分页的二种形式

1 单表 分页

ALTER PROCEDURE [dbo].[list]

@pageindex int,
@pagesize int ,
@rowcount float output,
@pageCount float output
AS
BEGIN

 select @rowcount=count(*) from Users set @pageCount=ceiling(@rowcount/@pagesize)
select * from
(select row_number() over(order by uId) as t ,* from Users) m
where t between (@pagesize*(@pageindex-1)+1)and (@pageindex*@pagesize)
 
END

 

ALTER PROCEDURE [dbo].[PageCut]
@tblName varchar(255), -- 表名
@strGetFields varchar(1000) = '*', -- 需要返回的列
@fldName varchar(255)='', -- 排序的字段名
@PageSize int, -- 页尺寸
@PageIndex int = 1, -- 页码
@OrderType bit = 0, -- 设置排序类型, 非 0 值则降序
@strWhere varchar(1500) = '' ,-- 查询条件 (注意: 不要加 where)
@Counts   int   out -- 返回记录总数, 非 0 值则返回 这里作运行后返回的记录总数分页用
AS
set nocount on
declare @strSQL varchar(5000) -- 主语句
declare @CountSQL nVarchar(4000)
declare @strTmp varchar(110) -- 临时变量

if @OrderType != 0
begin

--如果@OrderType不是0，就执行降序，这句很重要！
end
else

set nocount off
