Question

A few months ago our vendor added a capability to our ticketing system which lets us add any number of custom fields to a ticket. I’d like to query these fields out along with the other call information for reporting purposes, but each extensible field is stored as a row in the database. So basically you have something like this:

ext_doc_no    call_record    value 1             1001           Test 2             1001           test2 3             1001           moretest 

What I’d like is to query back:

1001    Test    test2    moretest 

I’ve tried to use PIVOT, but that’s rather demanding about things like using an aggregate function. Any other ideas on how to do this?

EDIT: I also tried querying each row separately into the main query, and using a function… but both methods are way too slow. I need something to get all the rows at once, PIVOT them and then join into the main query.
