[英]Using CASE statement in MDX for data from different hierarchy level
I have the following hierarchy created:我创建了以下层次结构:
I have written this particular query to get my result:我写了这个特定的查询来得到我的结果:
WITH MEMBER [Ecotassa] AS
CASE
WHEN [Tempo].[Anno].CurrentMember.MemberValue = '2011' THEN '9114646'
WHEN [Tempo].[Anno].CurrentMember.MemberValue = '2012' THEN '8787551.65'
WHEN [Tempo].[Anno].CurrentMember.MemberValue = '2013' THEN '8435651.26'
WHEN [Tempo].[Anno].CurrentMember.MemberValue = '2014' THEN '8917336.39'
WHEN [Tempo].[Anno].CurrentMember.MemberValue = '2015' THEN '9465533.37'
ELSE NULL
END
SELECT
{ [Measures].[Dato], [Ecotassa] } ON COLUMNS,
{ ([Tempo].[Periodo].[Mese Anno].MEMBERS) } ON ROWS
FROM [AGRO]
WHERE ([TipoMisura].[Tipo Misura].&[1], [TipoAnno].[Tipo Anno].&[2],
[TipoPeriodo].[Tipo Periodo].&[2],
[Mercato].[Mercato].&[1],
[Aziende].[Descrizione Codice Azienda].&[100 - BASF]);
The result that I am getting is:我得到的结果是:
This is not my desired result, for Ecotassa, I need to get the result for that particular year.这不是我想要的结果,对于 Ecotassa,我需要得到那一年的结果。 But I am getting null .但我得到null 。
Where am I going wrong with the query?我的查询哪里出错了?
This [Tempo].[Anno].CurrentMember
is equal to All
in your script hence it is choosing NULL
in the CASE
statement.这[Tempo].[Anno].CurrentMember
等于脚本中的All
,因此它在CASE
语句中选择NULL
。 I'd also be tempted to use [Tempo].[Periodo]
for year and also for date: rather than [Tempo].[Anno]
:我也很想使用[Tempo].[Periodo]
作为年份和日期:而不是[Tempo].[Anno]
:
I've also thrown [Measures].[y]
into the select so we can see if it is working ok.我还将[Measures].[y]
放入 select 中,以便我们查看它是否工作正常。
So try this:所以试试这个:
WITH
MEMBER [Measures].[y] AS
EXISTS(
[Tempo].[Periodo].[Anno].members,
[Tempo].[Periodo].CurrentMember
).ITEM(0).ITEM(0).Member_Caption
MEMBER [Measures].[Ecotassa] AS
CASE
WHEN [Measures].[y] = '2011' THEN '9114646'
WHEN [Measures].[y] = '2012' THEN '8787551.65'
WHEN [Measures].[y] = '2013' THEN '8435651.26'
WHEN [Measures].[y] = '2014' THEN '8917336.39'
WHEN [Measures].[y] = '2015' THEN '9465533.37'
ELSE NULL
END
SELECT
{
[Measures].[Dato]
,[Measures].[Ecotassa]
,[Measures].[y]
} ON COLUMNS,
[Tempo].[Periodo].[Mese Anno].MEMBERS ON ROWS
FROM [AGRO]
WHERE (
[TipoMisura].[Tipo Misura].&[1]
,[TipoAnno].[Tipo Anno].&[2]
,[TipoPeriodo].[Tipo Periodo].&[2]
,[Mercato].[Mercato].&[1]
,[Aziende].[Descrizione Codice Azienda].&[100 - BASF]
);
test script测试脚本
What does this return?这会返回什么?
WITH
MEMBER [Measures].[EcotassaTEST] AS
[Tempo].[Anno].CurrentMember.MemberValue
SELECT
{ [Measures].[Dato], [EcotassaTEST] } ON COLUMNS,
{ ([Tempo].[Periodo].[Mese Anno].MEMBERS) } ON ROWS
FROM [AGRO]
WHERE ([TipoMisura].[Tipo Misura].&[1], [TipoAnno].[Tipo Anno].&[2],
[TipoPeriodo].[Tipo Periodo].&[2],
[Mercato].[Mercato].&[1],
[Aziende].[Descrizione Codice Azienda].&[100 - BASF]);
