Hi Alex, I believe your database-design is not good ... think about a re-design or send us some info about your tables. Maybe we find a better solution...

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!
