null - 如何删除空值？

Question

如何删除 bottomcount 中的空值，即。我只想查看实际销售单位的产品，我尝试使用 nonempty 和 non empty 都没有成功。

with
member [Measures].[Amount Sold] as
    ([Measures].[Internet Sales Amount]),
format_string = "currency"

select {[Measures].[Amount Sold]}
on columns,
bottomcount(
order(

{[Product].[Product].Members},
([Measures].[Amount Sold]), bdesc),
5 )on rows

Answer 1

您可以使用 NOT ISEMPTY() 过滤 [Product].Members 以排除所有空值，然后对过滤后的集合进行底部计数。

with member [Measures].[Amount Sold] as
    ([Measures].[Internet Sales Amount]),
    format_string = "currency"
select 
    {[Measures].[Amount Sold]} on columns,
    order(
        bottomcount(
            filter({[Product].[Product].Members}, NOT ISEMPTY([Measures].[Amount Sold])),
            5,
            [Measures].[Amount Sold]),
        [Measures].[Amount Sold], bdesc) on rows

请注意 BottomCount() 将执行升序、中断层次结构排序，因此如果您想要降序，则需要在其之上执行 Order() .
