100的组合运算量太大, 用10个球演示一下
select DISTINCT * from [Sheet1$a1:a12] as a,[Sheet1$b1:b12] as b,[Sheet1$c1:c12] as c where a.A球+b.B球+C.C球=10

很高兴得到你的帮助,在这里先谢谢了。您说的100的组合运算量太大, 用10个球演示一下,你做的答案跟教程都很详细,可是我是个初学者,对于你给的答案“使用以下语句测算, 共有5151种放法
select count(*) from [Sheet1$a1:a102] as a,[Sheet1$b1:b102] as b,[Sheet1$c1:c102] as c where a.A球+b.B球+”我 还不会使用,您能把10变成100么?活着您教教我怎么用“使用以下语句测算, 共有5151种放法
有5151种放法
select count(*) from [Sheet1$a1:a102] as a,[Sheet1$b1:b102] as b,[Sheet1$c1:c102] as c where a.A球+b.B球+C.C球=100 |
