Assuming you are using Standard delphi db components and that this is a master detail...
Your master and detail would be linked on the PK in the master to the FK in the detail. The detail will be EOF when you have looped to the last detal record. Query.isEmpty will be true if there are no records. Hope that gets you started. Rob Marshland Engineering wrote: > I have two files. The second file is linked to the first.
