数据筛选的SQL语句问题!!
哎呀 
 好久没来这里啦,分也散得差不多咯。555...   
 今天来提个问题!~   
 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:   
 tid         aa   bb   cc   dd   ee 
 1               1      3         7      8      9               第一抽取次13789 
 2               4      6         7      8      10            第二抽取次46789 
 3               3      5         7      8      9               第三抽取次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--------------------抽出了的数加起来不在表中.   
 如select ..... from where cast(a as varchar) + cast(b as varchar) + cast(c as varchar) + cast(d as varchar) + cast(e as varchar) no in (select cast(aa as varchar)+cast(bb as varchar)+cast(cc as varchar)+cast(dd as varchar)+cast(ee as varchar) from ta)
------解决方案--------------------先把所有组合 存在临时表中 然后筛选
------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    
 declare @t2 table(id int) 
 insert into @t2  
       select 1 union select 2 union select 3 union select 4 
 union select 5 union select 6 union select 7 union select 8 
 union select 9 union select 10   
 select 
     n.* 
 from 
     (select  
          a.id aa,b.id bb,c.id cc,d.id dd,e.id ee 
      from  
          @t2 a,@t2 b,@t2 c,@t2 d,@t2 e 
      where  
          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)
