数据筛选的SQL语句问题！！

[噯卟釋手]

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）

按照楼主的要求a,b,c,d,e应该是不重复的5个数字所以修改部分 老乌龟的代码
WHILE @a <= 6
begin
set @b = @a+1
while @b <= 7
begin
set @c = @b+1
while @c <=8
begin
set @d = @c+1
while @d <= 9
begin
set @e = @d+1
while @e <= 10
begin
insert into test(a,b,c,d,e) values(@a,@b,@c,@d,@e)
set @e = @e + 1
end
set @d = @d + 1
end
set @c = @c + 1
end
set @b = @b + 1
end
set @a = @a + 1
end

最后100分拿出50分来与大家共享！~~

重复一下问题 上面有几个字顺序弄错咯 ^_^

2 4 6 7 8 10 第二次抽取46789

[噯卟釋手]

表ta的字段就是 tid aa bb cc dd ee 均为int型的tid自增

太罗嗦了~~

嘻~~

[dawugui]

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)

[dawugui]

上面的a,b,c,d,e代表你抽出来的五个数.

[砸死牛顿的苹果]

先把所有组合 存在临时表中 然后筛选

[噯卟釋手]

哎呀~~ 能不能说得明白点啊

主要是语句不太会写~~

郁闷哈~

[噯卟釋手]

晕~~

看来这个问题要不了了之咯~~

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)
