1、CSDNC邹徏写的一个通用存储q程
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[p_show]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[p_show]
GO
/*--实现分页的通用存储q程
昄指定表、视图、查询结果的WX?BR> 对于表中主键或标识列的情?直接从原表取数查询，其它情况使用临时表的Ҏ
如果视图或查询结果中有主?不推荐此Ҏ
如果使用查询语句,而且查询语句使用了order by,则查询语句必d含top 语句

@doCount bit = 0, -- q回记录L, ?0 值则q回
@OrderType bit = 0, -- 讄排序cd, ?0 值则降序
@strWhere varchar(1500) = '' -- 查询条g (注意: 不要?where)
AS
declare @strSQL varchar(5000) -- 主语?/P>
declare @strTmp varchar(110) -- 临时变量
declare @strOrder varchar(400) -- 排序cd
begin
replace(@strGetFields,'''','''''')
end
if @doCount != 0
begin
if @strWhere !=''
set @strSQL = 'select count(*) as Total from [' + @tblName + '] where ' + @strWhere
else
set @strSQL = 'select count(*) as Total from [' + @tblName + ']'
end
--以上代码的意思是如果@doCount传递过来的不是0Q就执行Ll计。以下的所有代码都是@doCount?的情?/P>
else
begin
if @OrderType != 0
begin
set @strTmp = '<(select min'
set @strOrder = ' order by [' + @fldName +'] desc'
--如果@OrderType不是0Q就执行降序Q这句很重要Q?/P>
end
else
begin
