Hello,
Thank your reply.

After reading the messages you pointed me at, i came to the conclusion that there is no automatic way to do it.
I mean, a table and some fields must be created on the database, but the actual version numbers must be updated by manually by the user!
I was looking for a way to do it automatically, that's why i was thinking of using the system tables. But you are right, triggers on system tables would not be restored after a backup on the database.

Oh well... I Guess i will have to maintain the version numbers manually!

Thank you very much for you help!
Obrigado na mesma!
