分享一个通用的分页SQL

又很久没写博客，今天记录一个SQLserver通用分页存储过程（适用于SqlServer2000及以上版本）

1.支持连表

2.支持条件查询

USE [MYDB] GO

/****** Object: StoredPRocedure [dbo].[SP_CommonPage]

SET QUOTED_IDENTIFIER ON GO

------------------------------------ --用途：分页存储过程(对有主键的表效率极高) --说明： ------------------------------------

CREATE PROCEDURE [dbo].[SP_CommonPage]

@tblName varchar(255), -- 表名

@fldName varchar(255), -- 主键字段名

@PageSize int = 10, -- 页尺寸

@PageIndex int = 1, -- 页码

@IsReCount bit = 0, -- 返回记录总数, 非 0 值则返回

@OrderType bit = 0, -- 设置排序类型, 非 0 值则降序

@strWhere varchar(1000) = '' -- 查询条件 (注意: 不要加 where)

AS

declare @strSQL varchar(6000) -- 主语句

declare @strTmp varchar(100) -- 临时变量(查询条件过长时可能会出错，可修改100为1000)

declare @strOrder varchar(400) -- 排序类型

if @OrderType != 0

begin

set @strTmp = '<(select min'

set @strOrder = ' order by [' + @fldName +'] desc'

end

else

begin

set @strTmp = '>(select max'

set @strOrder = ' order by [' + @fldName +'] asc'

end

set @strSQL = 'select top ' + str(@PageSize) + ' * from [' + @tblName + '] where [' + @fldName + ']' + @strTmp + '([' + @fldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' [' + @fldName + '] from [' + @tblName + ']' + @strOrder + ') as tblTmp)' + @strOrder

if @strWhere != ''

set @strSQL = 'select top ' + str(@PageSize) + ' * from [' + @tblName + '] where [' + @fldName + ']' + @strTmp + '([' + @fldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' [' + @fldName + '] from [' + @tblName + '] where ' + @strWhere + ' ' + @strOrder + ') as tblTmp) and ' + @strWhere + ' ' + @strOrder

if @PageIndex = 1

begin

set @strTmp =''

if @strWhere != ''

set @strTmp = ' where ' + @strWhere

set @strSQL = 'select top ' + str(@PageSize) + ' * from [' + @tblName + ']' + @strTmp + ' ' + @strOrder

end

if @IsReCount != 0

set @strSQL = 'select count(*) as Total from [' + @tblName + ']'+' where ' + @strWhere

exec (@strSQL)

GO
