代码如下:


------------------------------------ 
--用途:分页存储过程(对有主键的表效率极高) 
--说明: 
------------------------------------ 
ALTER PROCEDURE [UP_GetRecordByPage] 
@tblName varchar(255), -- 表名

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

begin

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