Question

是否可以在MDX中循环几个变量？我想基于3个条件过滤我的查询，每个条件包含2 * 2 * 3个变量。我正在寻找一种比改变WHERE子句12次更好的方法来制作12个表并最终一起追加。

这就是我想象的样子：

Market  2015 2016 2017 Condition1 Condition2 Condition3
Market 1 $$   $$   $$      ABC      Direct       B2B
Market 1 $$   $$   $$      ABC      Direct       B2C
Market 1 $$   $$   $$      ABC      Direct       Other
Market 1 $$   $$   $$      ABC      Trade        B2B
Market 1 $$   $$   $$      ABC      Trade        B2C
Market 1 $$   $$   $$      ABC      Trade        Other
Market 1 $$   $$   $$      DEF      Direct       B2B
Market 1 $$   $$   $$      DEF      Direct       B2C
Market 1 $$   $$   $$      DEF      Direct       Other
Market 1 $$   $$   $$      DEF      Trade        B2B
Market 1 $$   $$   $$      DEF      Trade        B2C
Market 1 $$   $$   $$      DEF      Trade        Other
       ...

编辑：这是我的查询（可能不是最佳的，因为我是MDX中的总菜鸟）：

所以现在我得到了这三年每个市场的年度总和。现在我想在上面提到的组中进一步分割这个总数。

Answer 1

我从一个错误的角度思考它，我用交叉连接解决了它（我之前从未听说过）。

这是一篇关于交叉连接的好文章： http://www.databasejournal.com/features/mssql/article.php/10894_3334631_3/MDX-Essentials-Basic-Set-Functions-The-CrossJoin-Function.htm
