自己收集比较强大的分页存储过程 推荐

时间:2019-12-11 14:08     来源/作者:MSSQL教程网

(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)。 

复制代码代码如下:


set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
go 
ALTER PROCEDURE [dbo].[proc_page] 

@tblName nvarchar(200), ----要显示的表或多个表的连接lihu 
@fldName nvarchar(500) = '*', ----要显示的字段列表 
@pageSize int = 10, ----每页显示的记录个数 
@page int = 1, ----要显示那一页的记录 
@fldSort nvarchar(200) = null, ----排序字段列表或条件 
@Sort bit = 0, ----排序方法,0为升序,1为降序(如果是多字段排列Sort指代最后一个排序字段的排列顺序(最后一个排序字段不加排序标记)--程序传参如:' SortA Asc,SortB Desc,SortC ') 
@strCondition nvarchar(1000), ----查询条件,不需where 
@ID nvarchar(150), ----主表的主键 
@Dist bit = 0, ----是否添加查询字段的 DISTINCT 默认0不添加/1添加 
@pageCount int = 1 output, ----查询结果分页后的总页数 
@Counts int = 1 output ----查询到的记录数 

AS 
SET NOCOUNT ON 
Declare @sqlTmp nvarchar(1000) ----存放动态生成的SQL语句 
Declare @strTmp nvarchar(1000) ----存放取得查询结果总数的查询语句 
Declare @strID nvarchar(1000) ----存放取得查询开头或结尾ID的查询语句 
Declare @strSortType nvarchar(10) ----数据排序规则A 
Declare @strFSortType nvarchar(10) ----数据排序规则B 
Declare @SqlSelect nvarchar(50) ----对含有DISTINCT的查询进行SQL构造 
Declare @SqlCounts nvarchar(50) ----对含有DISTINCT的总数查询进行SQL构造 
declare @timediff datetime --耗时测试时间差 
select @timediff=getdate() 
if @Dist = 0 
begin 
set @SqlSelect = 'select ' 
set @SqlCounts = 'Count(*)' 
end 
else 
begin 
set @SqlSelect = 'select distinct ' 
set @SqlCounts = 'Count(DISTINCT '+@ID+')' 
end

end
