我仍在掌握MDX,我正在寻求帮助。这是我的MDX查询:
CREATE MEMBER CURRENTCUBE.[Measures].[Fake]
AS
IIF(
(
(
[Sales Data].[Ship-to No].CurrentMember
,[Sales Data].[Price Type].&[Core]
,[Measures].[Sales - Local Currency]
)
/ (
[Sales Data].[Ship-to No].CurrentMember,
[Sales Data].[Price Type].[(All)].[ALL],
[Measures].[Sales - Local Currency]
)
) > 0.9
,1
,NULL
),
VISIBLE = 1;
CREATE MEMBER CURRENTCUBE.[Measures].[Test Calc]
AS
SUM(
Descendants(
[Sales Data].[Ship-to No].CurrentMember
,[Sales Data].[Ship-to No].[Ship-to No]
),
[Measures].[Fake]
),
VISIBLE = 1;
SalesData是事实表,基本计算是计算销售额超过价格类型“核心”的90%的客户数量。
查询目前大约需要5秒才能完成,但我认为如果根据http://sqlblog.com/blogs/mosha/archive/2008/07/29/product-volatility-optimizing-mdx-with-mdx-studio.aspx不使用CurrentMember,这可能会更快
但我不知道从哪里开始改变这个,有人能帮助我提高效率吗?
答案 0 :(得分:0)
如果从第一个小节中删除当前成员会有什么不同吗?
CREATE MEMBER CURRENTCUBE.[Measures].[Fake]
AS
IIF(
(
(
[Sales Data].[Price Type].&[Core]
,[Measures].[Sales - Local Currency]
)
/ (
[Sales Data].[Price Type].[(All)].[ALL],
[Measures].[Sales - Local Currency]
)
) > 0.9
,1
,NULL
),
VISIBLE = 1;
对于您在第二项指标中使用的当前成员,可能现有就足够了:
CREATE MEMBER CURRENTCUBE.[Measures].[Test Calc]
AS
SUM(
EXISTING [Sales Data].[Ship-to No].[Ship-to No].MEMBERS
,[Measures].[Fake]
),
VISIBLE = 1;
