自己收集比较强大的分页存储过程 推荐

2022-05-24 0 952

(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 @SqlCounts = ‘Count(DISTINCT ‘+@ID+’)’
