ORACLE Forms querying with child block

I have a form with a parent and child block related by a field which is the primary key of the parent block (and thus a foreign key in the child block). There was a request to be able to enter criteria in a child block field for a query which would then bring back the set of all related rows in the two blocks in which the particular child block field value matched the given criteria. Is this legal or meaningful and if so how can it be done? Received on Mon Jul 20 1998 - 00:10:18 CDT
