Question

I have Object1 and junction table and Object2. Object2 is table that has many junction tables, but can have only one junction table torefrencing to it. When table Object1 is removed, then junction table and Object2 should be removed. How can I make foreign keys in this situation? But when Object2 is removed, then only junction table should be removed, not Object1. I’m using SQL Server 2008.

Answer 1

You could

• apply CASCADING DELETES to your foreign key from your junction table to Object2.
• add a Trigger to Object1, check for deletion and delete the corresponding records in your junction table and Object2.
