I am defining my own id (primary key) for the database table using the system time as a varchar(11). How do I may this as an id?

Please, any example would be helpful

TIA

There are several ways to do that, but I don't think its a good idea. Why can't you use a simple number sequence?

I am (trying to) migrating my project over to Hibernate and need to preserve the installed base (which is working fine). I suppose I will take your advice, but at this time I would like to query with the keys I have in place.
Is this possible to do, with an I to migrate it to a Hibernate generated key?

TIA

Sure, have a look at IdentifierGenerator and the rest of the documentation, which is very extensive about that topic.
