Currency Conversion

I am using the cube intelligence wizard to add currency conversions. I have defined everything properly. At a certain moment, a query is launched against my Oracle backend. This is the query:

SELECT "Reporting Currency".*

FROM

(

SELECT "CCDM_IL"."CCDM_IL_CRRN_T"."CURRENCY_CODE","CCDM_IL"."CCDM_IL_CRRN_T"."CURRENCY_NAME"

FROM "CCDM_IL"."CCDM_IL_CRRN_T"

WHERE [CURRENCY_NAME] IN ('Euro') UNION

SELECT

DISTINCT

'Local' "Local",'Local' "Local 2"

FROM "CCDM_IL"."CCDM_IL_CRRN_T"

)

"Reporting Currency"

Now, this query returns the error "ORA-00936: Missing Expression". This error is caused by the square brackets around currency_name in the where clause. Once I remove these the query runs fine.

How can I make this query work?

Thanks

By the look of it this is coming from a named query in the DSV. Check if the wizard has actually inserted the square brackets into the named query in the DSV. If so, you should be able to edit the definition to remove the square brackets.|||

The query is generated by the BI wizard itself. In my DSV, I do not have a named query for the currency dimension. It is a real table...

The currency dimension has one attribute for which the key is set to CCDM_IL_CRRN_T.CURRENCY_CODE and the name is set to CCDM_IL_CRRN_T.CURRENCY_NAME.

|||Can you double check? Right click on the object in the DSV and tell me if the third menu item you see says either "Edit Named Query..." or "Replace Table with...". I would not normally ask, but the reason I am is becuase the BI wizard actually generates objects in your DSV and cubes, but it does not actually send any queries to the relational source.|||

For the table CCDM_IL_CRRN_T, it definitely says "Replace Table".

Have you been able to isolate if this error is coming from a dimension or from a partition? (by processing objects associated with currencies one at a time)

Try going into SSMS, right clicking on the database and generating an alter script. This will generate a heap of xmla, search through this for the table name in square brackets or some other identifiable portion of this problem query. You can then either run the alter script and then import the database back into BIDS or hopefully this will help identify where exactly the problem query is coming from.

In the script, the square brackets do not occur. Extracts where currency_name occurs:

<NameColumn>

<DataType>WChar</DataType>

<DataSize>255</DataSize>

<Source xsi:type="ColumnBinding">

<TableID>CCDM_CCDM_IL_CRRN_T</TableID>

<ColumnID>CURRENCY_NAME</ColumnID>

</Source>

</NameColumn>

<xs:element name="CURRENCY_NAME" msprop:FriendlyName="CURRENCY_NAME" mspropBig SmilebColumnName="CURRENCY_NAME" minOccurs="0">

<xsTongue TiedimpleType>

<xs:restriction base="xsTongue Tiedtring">

<xs:maxLength value="255" />

</xs:restriction>

</xsTongue TiedimpleType>

</xs:element>
