How can I temporarily disable all constraints in a Table in Firebird 2.1?

Question

I want to disable all Foreign key constraints and re-enable them after, is there some way to do that?

I know that SQLServer allows that, but what about Firebird?

Answer 1

AFAICT foreign keys can't be disabled in Firebird up to 2.1.
You'd have to drop and recreate them.
