Question

I am pretty new to SSAS, OLAP and MDX syntax.

So I have this MDX to query the cube by TSQL (by linked server to SSAS) and it works fine:

select * from openquery(GCUBE, 
'SELECT NON EMPTY { [Measures].[Valore] } ON COLUMNS, 
NON EMPTY {
( [Prodotti].[Top Marca].[Top Marca].ALLMEMBERS 
* [Prodotti].[Top Codice].[Top Codice].ALLMEMBERS 
* [Agenti].[Vw Agenti].[Vw Agenti].ALLMEMBERS
* [Calendario].[AnnoMese].[Mese].ALLMEMBERS 
* [Prodotti].[Ordinamento].[Ordinamento].ALLMEMBERS 
* [Prodotti].[Top].[Top].ALLMEMBERS )
}
DIMENSION PROPERTIES MEMBER_CAPTION
ON ROWS FROM ( SELECT ( { [Calendario].[Anno].&[2012] } )
ON COLUMNS FROM ( SELECT ( { [Agenti].[Vw Agenti].&[005] } )
ON COLUMNS FROM [Vendite])) WHERE (  [Calendario].[Anno].&[2012] )'
)

Well, the [Prodotti].[Top Marca] is a dimension based on a table with the 50 top selling brands and this MDX is filtered by a specific ID Agent [Vw Agenti] = 005.

The purpose of the query is to find out how the agent is selling the company’s 50 top selling brands.

The query works fine but there is one brand not sold by this agent and I need to show the empty row.

The figure below shows the missing record relative to the position (rank) 31.

I understand the concept about NON EMPTY but I can’t find the right syntax to also show the empty record.

How should I modify the MDX?

I tried to remove NON EMPTY but I get a generic error:

Cannot execute the query against OLE DB provider "MSOLAP" for linked server "GCUBE"

Do I need to change the dimension Top Marca in the cube?

Thanks in advance to anyone who can help me or give the right tips to solve this.

Answer 1

I’m not a specialist of SSAS/TSQL, but I would try a simple request first :

SELECT 

[Measures].[Valore]ON COLUMNS, 

NON EMPTY [Prodotti].[Top Marca].[Top Marca].ALLMEMBERS ON ROWS 

FROM ( SELECT { [Calendario].[Anno].&[2012] } ON COLUMNS 
  FROM ( SELECT { [Agenti].[Vw Agenti].&[005] } ON COLUMNS 
    FROM [Vendite] 
  )
) '

Any way to run it without this TSQL stuff?
