对于表中主键或标识列的情况,直接从原表取数查询，其它情况使用临时表的方法
如果视图或查询结果中有主键,不推荐此方法--邹建 2003.09--*//*--调用示例
exec p_show '地区资料' exec p_show '地区资料',5,3,'地区编号,地区名称,助记码','地区编号'
--*/
/*--调用示例 *********************************注意加top 100 percent******************
use haihuioa
exec p_show 'select top 100 percent * from clientservicelog where fkid=1 and pdate>=''2003-12-1'' and pdate<=''2003-12-3'' ',5,1,'','pdate asc'
go
--*/
/*
因为要顾及通用性,所以对带排序的查询语句有一定要求.如果先排序,再出结果.就是:exec p_show 'select top 100 percent * from 地区资料 order by 地区名称',5,3,'地区编号,地区名称,助记码'
--查询语句加上:top 100 percent

ViewState保存 SQL语句 起始页面 排序字段 正序asc还是desc这样就可以很好的调用了
这样做是为了 排序 和分页 及查询的 需要
如 你没这么高的要求 可以自己手工写
