How to implement select operation on DB adapter?

Question

Hi, I have a requirement in which I have to retrieve a metadata value from metadata table using a DB Adapter and accordingly make decision like which flow to take using a Routing Service. If financialSystem1 value is retrieved, follow path1 or if financialSystem2 is retrieved from DB, follow path2.
How do I do this? How do I pass the value returned by DB adapter to the next Routing Service and use this value in the filter expression?
Thanks,

Thanks Eric. I am really pleased by your quick responses to my other postings. We are working on a critical project and we have picked Oracle ESB to be the middle ware.
Coming to the problem:
After selecting for a perticular record, in the reply part, I placed a filter expression as
/inp1:CStripesReqsCollection/inp1:CStripesReqs/inp1:fundCode = '10'. But the message flow stops right there and doesnt flow any further.(By the way it is considering the namespace as inp1=http://xmlns.oracle.com/pcbpel/adapter/db/top/InterfaceTable)
However, if I remove the filter condition, the result flows to the next node(For now a file write operation). and when it writes out, I check the contents and the contents satisfy the filter expression that I wrote. It is just not recognizing the filter expression that I am writing.
Here is the XML that it wrote to output file.
<?xml version="1.0" ?><CStripesReqsCollection xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/top/DBSelect">
<CStripesReqs>
<reqIntfId>100023330353</reqIntfId>
<fundCode>10</fundCode>
</CStripesReqs>
</CStripesReqsCollection>
Do you see any obvious mistake here?
Thanks,
