復制代碼代碼如下:

CREATE PROCEDURE [dbo].[up_Pager]
@table varchar(2000), --表名
@col varchar(50), --按該列來進行分頁
@orderby bit, --排序,0-順序,1-倒序
@collist varchar(800),--要查詢出的字段列表,*表示全部字段
@pagesize int, --每頁記錄數
@page int, --指定頁
@condition varchar(800) --查詢條件
AS
DECLARE @sql nvarchar(4000),@where1 varchar(800),@where2 varchar(800),
@total_Item int,@total_Page int
IF @condition is null or rtrim(@condition)=''
BEGIN--沒有查詢條件
SET @where1=' WHERE '
SET @where2=' '
END
ELSE
BEGIN--有查詢條件
SET @where1=' WHERE ('+@condition+') AND '--本來有條件再加上此條件
SET @where2=' WHERE ('+@condition+') '--原本沒有條件而加上此條件
END
SET @sql='SELECT @total_Item=CEILING((COUNT(*)+0.0)'+') FROM '+@table+ @where2
