Title:
Referential Integrity question
All,
I have two file in a one to many relationship. I am trying to restrict insertion of records into a child table unless a parent record exists, but I have found that the act of inserting a record in the child causes the trigger to fail unless I have a dummy record in the parent with a blank key.
Two question:
1 Is there a way to insert a record in the child with the parent key already replaced?
2. Is putting a dummy record in the parent the only way around this problem?
TIA
Rex
