高难度的数据筛选问题!!!!!!
看来提问标题要起好呀      
 不然都没有人气滴(最后50分咯   555...)   
 -------------------------------------------------------   
 有1----10十个数(每次随机抽5个按序排列)   
 表ta里已有选取的记录: 
 表ta的字段就是   tid      aa      bb   cc   dd   ee         均为int型的      tid自增   
 tid         aa   bb   cc   dd   ee 
 1               1      3         7      8      9               第一次抽取13789 
 2               4      6         7      8      10            第二次抽取46789 
 3               3      5         7      8      9               第三次抽取35789   
 问:如何列出还那些没有出现过的组合啊? 
 (肯定有很多,如12345,23456等)

------解决方案--------------------declare @t1 table(tid int,aa int,bb int,cc int,dd int,ee int) 
 insert into @t1 select 1,1,3,7,8,9  
 insert into @t1 select 2,4,6,7,8,10 
 insert into @t1 select 3,3,5,7,8,9

          a.id <b.id and b.id <c.id and c.id <d.id and d.id <e.id) n 
 where 
     not exists(select 1 from @t1 where aa=n.aa and bb=n.bb and cc=n.cc and dd=n.dd and ee=n.ee)
------解决方案--------------------要写循环逐一判断了,麻烦.我试试看.
