这篇文章主要介绍了SqlServer 2000、2005分页存储过程整理,本文给出了4个实现版本,还给出二分分页过程,需要的朋友可以参考下
@RecordCount int output,@ReturnCount bit,@QueryStr nvarchar(1000)='table1',--表名、视图名、查询语句@PageSize int=20, --每页的大小(行数)@PageCurrent int=2, --要显示的页 从0开始@FdShow nvarchar (2000)='*', --要显示的字段列表@IdentityStr nvarchar (100)='id', --主键@WhereStr nvarchar (2000)='1=1',@FdOrder nvarchar(100)='desc' --排序 只能取desc或者ascasset nocount ondeclare@sql nvarchar(2000)if @WhereStr = '' begin set @WhereStr = '1=1'endif @ReturnCount=1 begin declare @tsql nvarchar(200) set @tsql=N'select @RecordCount = count(*) from ' + @QueryStr + ' where ' + @WhereStr exec sp_executesql @tsql,N'@RecordCount int output',@RecordCount outputendif @PageCurrent = 0 begin set @sql = 'select top ' + cast(@PageSize as nvarchar(3)) + ' ' + @FdShow + ' from ' + @QueryStr + ' where ' + @WhereStr + ' order by ' + @IdentityStr + ' ' + @FdOrderendelse begin if upper(@FdOrder) = 'DESC' begin set @sql = 'select top ' + cast(@PageSize as nvarchar(3)) + ' ' + @FdShow + ' from ' + @QueryStr + ' where ' + @WhereStr + ' and ' + @IdentityStr + '< ( select min(' + @IdentityStr + ') from (select top ' + cast(@PageSize*@PageCurrent as nvarchar(10)) + ' ' + @IdentityStr + ' from ' + @QueryStr + ' where ' + @WhereStr + ' order by ' + @IdentityStr + ' desc) as t) order by ' + @IdentityStr + ' desc' end else begin set @sql = 'select top ' + cast(@PageSize as nvarchar(3)) + ' ' + @FdShow + ' from ' + @QueryStr + ' where ' + @WhereStr + ' and ' + @IdentityStr + '> ( select max(' + @IdentityStr + ') from (select top ' + cast(@PageSize*@PageCurrent as nvarchar(10)) + ' ' + @IdentityStr + ' from ' + @QueryStr + ' where ' + @WhereStr + ' order by ' + @IdentityStr + ' asc) as t) order by ' + @IdentityStr + ' asc' endend--print @sqlexecute(@sql)

二分分页过程:
