自己收集比较强大的分页存储过程 推荐

来源:网络整理  作者:网络  发布时间:2020-12-07 22:24
这两天帮朋友修改一个项目,看到一个存储过程,感觉性能非常高。于是,整合自己以前搜集的比较好的存储过程,...
+' where '+@ID+' >(select max('+ @ID +') from('+ @SqlSelect+' top '+ CAST(@pageSize*(2-2)+@lastcount as Varchar(20)) +' '+ @ID +' from '+@tblName
+' '+ @strCondition +' order by '+ @fldSort +' '+ @strFSortType
end
end
@pageCount int = 1 output, ----查询结果分页后的总页数
+' where 1=1 ' + @strCondition + ' order by '+ @fldSort +' '+ @strFSortType

end
SET NOCOUNT OFF
Declare @SqlSelect nvarchar(50) ----对含有DISTINCT的查询进行SQL构造
set @lastcount = @pagesize
ALTER PROCEDURE [dbo].[proc_page]
end
+' order by '+ @fldSort +' '+ @strSortType+') AS TempTB'+' order by '+ @fldSort +' '+ @strFSortType
set @strTmp=@SqlSelect+' * from ('+@SqlSelect+' top '+ CAST(@pageSize as VARCHAR(4))+' '+ @fldName+' from '+@tblName
if @pageIndex<2 or 2<=@pageIndex / 2 + @pageIndex % 2 --前半部分数据处理
+' where '+@ID+' <(select min('+ @ID +') from('+ @SqlSelect+' top '+ CAST(@pageSize*(@page-2)+@lastcount as Varchar(20)) +' '+ @ID +' from '+@tblName
else
end

复制代码 代码如下:

begin
set @strFSortType=' ASC '
exec sp_executesql @strTmp,N'@Counts int out ',@Counts out
+' '+ @strCondition +' order by '+ @fldSort +' '+ @strFSortType
--/*-----数据分页2分处理-------*/
end
set @strSortType=' ASC '
+' where '+@ID+' >(select max('+ @ID +') from('+ @SqlSelect+' top '+ CAST(@pageSize*(@page-2)+@lastcount as Varchar(20)) +' '+ @ID +' from '+@tblName
(下面的代码原来我想用折叠的代码的,但是在google里面老是添加不了折叠的代码,所以就整屏的贴出来了,望大家不要见外。)
朋友的比较好的存储过程。优点是:性能非常的高,每次查询都是根据ID查询,每次都是对一半的数据进行分页。缺点是:当有多个排序条件时,分页数据显示会出现问题。(该问题在第二个网友的分页存储过程中有解决的方法)。
