MDX常用函数

1.ParallelPeriod

--ParallelPeriod
with member [Measures].[a1] As 'ParAllelPeriod(Year,2,[时间].[月].&[2011]&[12])'
select ParAllelPeriod([时间].[月].&[2011]&[10].level,1,[时间].[月].&[2011]&[10]) on columns,
[Measures].[会员人数] on rows
from [BSUSYS_New]

2.Topcount

select [Measures].[会员人数] on 0,
topcount([时间].[月].[月],5,[Measures].[会员人数]) on 1
from [BSUSYS_New]

3.bottomcount

select [Measures].[会员人数] on 0,
bottomcount([时间].[月].[月],5,[Measures].[会员人数]) on 1
from [BSUSYS_New]

4.Toppercent(这些元素的累积合计至少为指定的百分比即指定月份的会员人数总和至少是总会员人数的50%)

select [Measures].[会员人数] on 0,
Toppercent([时间].[月].[月],50,[Measures].[会员人数]) on 1
from [BSUSYS_New]

5.bottompercent

select [Measures].[会员人数] on 0,
bottompercent([时间].[月].[月],50,[Measures].[会员人数]) on 1
from [BSUSYS_New]

6.TOPSUM(这些月份的累计会员>=1600000)

select [Measures].[会员人数] on 0,
TOPSUM([时间].[月].[月],1600000,[Measures].[会员人数]) on 1
from [BSUSYS_New]

7.BOTTOMSUM

select [Measures].[会员人数] on 0,
BOTTOMSUM([时间].[月].[月],500,[Measures].[会员人数]) on 1
from [BSUSYS_New]

8.Filter

select [Measures].[会员人数] on 0,
filter([时间].[月].[月],[Measures].[会员人数]>100000) on 1
from [BSUSYS_New]

9.generate(将集合应用到另一集合的每个成员)

复制代码
--Generate 最常见的实际用法是为一组成员计算复杂集表达式，如 TopCount。
select [Measures].[会员人数] on 0,
generate ([时间].[年].[年].members,
TOPcount([时间].[年].currentmember*[会员 - 注册门店].[省].[省].members,2,[Measures].[会员人数])) on 1
from  [BSUSYS_New]
/*将年份跟会员人数排名前2名的省份的集进行简单交叉联接将
显示所有时间的前2个省份（每年都重复）,而不是每年的前两名省份*/
select [Measures].[会员人数] on 0,
[时间].[年].[年].members*TOPcount([会员 - 注册门店].[省].[省].members,2,[Measures].[会员人数]) on 1
from  [BSUSYS_New]
--以下示例说明如何使用 Generate 返回字符串：
with member MEASURES.GENERATESTRINGDEMO AS
generate ([时间].[年].[年].members,[时间].[年].currentmember.name)
member MEASURES.GENERATEDELIMITEDSTRINGDEMO AS
generate ([时间].[年].[年].members,[时间].[年].currentmember.name," and ")
select {MEASURES.GENERATESTRINGDEMO,MEASURES.GENERATEDELIMITEDSTRINGDEMO }on 0
from [BSUSYS_New]
复制代码

10.Descendants(Descendants 函数中的成员和级别必须属于同一层次结构)

select [Measures].[订单数] on 0,
descendants([创建时间].[年季月层次].[年].&[2011],[创建时间].[年季月层次].[月],SELF)  on 1
from YHDJBLMDataDW

         )
   ), FORMAT_STRING = '0%'
SELECT {[Measures].[商品小票数], Measures.x} ON 0,

   Descendants 
      (

         [商品].[旧品类层次].[旧小品类], SELF 
      )
} ON 1
