------------------------------------

--用途：支持任意排序的分页存储过程

--说明：

------------------------------------

CREATE PROCEDURE [dbo].[UP_GetRecordByPageOrder]

@tblName varchar(255), -- 表名

@fldName varchar(255), -- 显示字段名

@OrderfldName varchar(255), -- 排序字段名

@StatfldName varchar(255), -- 统计字段名

@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 [' + @OrderfldName +'] desc'

end

else

begin

set @strTmp = '>(select max'

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

end

+ @tblName + '] where [' + @OrderfldName + ']' + @strTmp + '(['

+ @OrderfldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' ['

+ @OrderfldName + '] from [' + @tblName + ']' + @strOrder + ') as tblTmp)'

+ @strOrder
