Question

Is it possible to use the value for a row from a named calculation as part of the T-SQL for another named calculation?

I am using BIDS to modify a data source view for a SS 2005 SSAS cube I have. I use a named calculation to associate the AccountID to each row in another table:

(SELECT c.ACCOUNTID FROM sysdba.CONTACT c WHERE c.CID ={current-table}.CID)

These calculations run in a few seconds. If I have another named calculation that nests that command, it runs very slow, it takes minutes. An example would be:

(SELECT a.TYPE FROM ACCOUNT a WHERE a.ACCOUNTID = (SELECT c.ACCOUNTID FROM sysdba.CONTACT c WHERE c.CID ={current-table}.CID))

Is there some way to execute something like:

(SELECT a.TYPE FROM ACCOUNT a WHERE a.ACCOUNTID = {current-table}.AccountID)

Obviously, that doesn’t work when I try it. It tells me that it’s an invalid column ID.

Answer 1

Give this a try

SELECT a.TYPE 
FROM ACCOUNT a 
JOIN sysdba.CONTACT c ON a.ACCOUNTID = c.ACCOUNTID
WHERE c.CID ={current-table}.CID
