Data Foundation table joins with filters (multi-conditional joins)

Question

My environment: Crystal Server 2011, Business View Manager 14.0.2.364, Crystal Reports 2011 with SP2 and FP28
In our existing database we make use of a single lookup table for many different types of selection lists.
For example, the lookup table might have selections for all of the US States (ex: NonUniqueIDValue = 123,  Value1=TX, Value2=Texas, LookupType=US_STATES) and another list of selections for OrderStatus (ex: NonUniqueIDValue = 123,   Value1=OPEN, Value2=NULL, LookupType=ORDER_STATUS).
It is necessary to supply addtional filtering on the join statement since the IDVaule for these entries are NOT unique.
Using SQL written joins for the two examples above would look like this:
join lookupTable on lookupTable.NonUniqueIDValue = mainTable.US_StateID AND lookupTable.LookupType = 'US_STATES'
join lookupTable on lookupTable.NonUniqueIDValue = mainTable.OrderStatus AND lookupTable.LookupType = 'ORDER_STATUS'
I am new to Business Views and don't readily see a solution since it appears the DF Linking window only suports single basic conditional testing (<, >, =, etc) . How can I accomplish this in my DF or elsewhere in the BV?
I would greatly appreciate any feedback or insight anyone might have on how to accomplish these kinds of filtered joins.
Thanks in advance...

Hi Paul
If the query returns 100,000,000 rows, there will be performance issues of the report based on the connection and the datasource you are using.
If you use a Command Object or a Stored Procedure the query will be directly executed at the database level and the performance will not be affected much.
Hope this helps!
Thanks
