Hi, I need a where clause in following situation:
Say I want to query two tables: A and B. In table A there is field Afn, while in table B there ere 3 fields: Bfn1, Bfn2 and Bfn3. I want to compose a query, in which the where clause can do this: if A.Afn=1, then check Bfn1, if A.Afn=2, then check Bfn2, if A.Afn=3, then check Bfn3. So how I compose a where clause to do this? Thanks in advance!
