I am trying to get two different types of data from a database. We have shipments that go to vendors and of course come back. We have a table that I can get the data in and out from, but here's the problem. The table has two fields that I need to look at so that I don't get duplications. The receipts have a transaction number , but no job # but I can link to a different table with the job # (we'll call that field "A"). The shipments have a job number (we'll call "B"), but no transaction numbers.
so can I create a field let's call it "C", where I can make it reflect the value of the "A" or "B" whichever is not null?
