Shouldn't need to declare them at all if never used. The one caveat though would be to make sure that an INSERT statement can succeed without them -- e.g. if of1 is a NOT NULL column and does not have a default, then __PACKAGE__->create() statements are going to bomb.

Thank you, davidrw.
I am only reading from the database, no inserts or updates.
Anyway, in case of some unexpected behaviour, I'll know where the problem can be.
Thank you.
