SQL存储过程分页（通用的拼接SQL语句思路实现）

多表通用的SQL存储过程分页

案例一：

USE [Community]
GO

/****** Object:  StoredProcedure [dbo].[Common_PageList]    Script Date: 2016/3/8 13:44:58 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO




CREATE PROCEDURE [dbo].[Common_PageList]
(
@tab nvarchar(200),---表名
@strFld nvarchar(max), --字段字符串
@strWhere nvarchar(max), --where条件 
@PageIndex int, --页码
@PageSize int, --每页容纳的记录数
@Sort nvarchar(255), --排序字段及规则,不用加order by
@Total int output --总数
)
AS
declare @strSql nvarchar(max)
set nocount on;

set @strSql=' SELECT * FROM (SELECT ROW_NUMBER() 
  OVER(ORDER BY ' + @Sort + ') AS rownum, ' + @strFld + ' FROM ' + @tab + ' where 1=1 ' + @strWhere + ') AS Dwhere
  WHERE rownum BETWEEN ' + CAST(((@PageIndex-1)*@PageSize + 1) as nvarchar(20)) + ' and ' + cast((@PageIndex*@PageSize) as nvarchar(20))
  exec (@strSql)
  --print @strSql

 set @strSql='SELECT @Total = COUNT(0) FROM ' + @tab + ' WHERE 1=1 ' + @strWhere 
 --print @strSql
 EXECUTE sp_executesql @strSql,N'@Total INT OUTPUT',@Total OUTPUT

set nocount off;

分页功能可以简化整合成统一的 SQL语句分页壳子 功能：
