Am I? Well, I haven't read the JDBC 4.0 spec (because it isn't likely to be relevant to me for at least two years). I was just giving a general example.Originally posted by D Rog:
I understand, you are talking about ROWID_VALID_SESSION and below.
I suppose you could. But using that row ID as a foreign key in a different table could be problematic. The database I do a lot of work on allows you to reorganize a table to get rid of deleted rows. When you do that, the row ID of many rows will change. That would break all the foreign keys in the other tables with no way of repairing them.

Thanks,Originally posted by vu lee:
....
If database permits using rowid as primary key, then I suppose the integrity contraint would take care of it.
