When I compare trigger (using "compare user objects") which is disable and not exists in target db, PL\SQL Developer doesn't put "alter trigger ... disable" in generated script.
Well, I understand, but I think it should be an option in preferences window. It's very easy to forget about disable triggers and put them into target db as enable. Operations on tables could make a lot of problems than.
How about 'deferable' constraints? PL\SQL Developer can compare this constraint's status! If think it is similar situation.
