I have a problem with dBaseIII+ syntax and would appreciate any help.
I have two relations with join-able attributes (say ID) and I need
to find out those ID's that exist in one and don't exist in the other.
In SQL I can use the NOT EXISTS syntax; in QUEL I can use the
ANY...=0 syntax; and in Rbase V I can use the SUBTRACT operator
(which really makes the most sense). My question is what is the
appropriate syntax in dBase?
