「DESCENDANTS」和「0，LEAVES」是什麼意思？

Question

我有以下MDX查詢：

select {[Measures].[Internet Sales Amount]} on axis(0), 
DESCENDANTS({[Customer].[Education].[All Customers].[Bachelors], 
      [Customer].[Education].[All Customers].[Graduate Degree]},0,LEAVES) on axis(1) , 
DESCENDANTS({[Geography].[Country].[All Geographies].[Australia], 
     [Geography].[Country].[All Geographies].[Canada], 
     [Geography].[Country].[All Geographies].[France]},0,LEAVES) on axis(2) 
from [Adventure Works] 

什麼DESCENDANTS和0, LEAVES是什麼意思？

Answer 1

聽起來奇怪（生成？）請求;它意味着返回成員級別的成員後代（指定爲第一個參數）。我猜這相當於0，SELF在這種情況下，因此相當於成員通過的參數：

{ 
[Geography].[Country].[All Geographies].[Australia], 
[Geography].[Country].[All Geographies].[Canada], 
[Geography].[Country].[All Geographies].[France] 
}
