our db has possiblity to add two readonly system columns to each table: timestamp of creation and update.
But that was introduced in latest version (v15) of DB and we can't force our customers to buy upgrade.
If I add them those columns to our major tables, would it be possible some how during application start
remove them from Aurelius internal structures if I notice that our DB version isn't new enough, so that only xdataservers running over v15 can see those columns
or is it just better to compile two versions?
Did you have a look at Dynamic Properties? It may be what you're looking for
Thanks, I have totally forgotten that.
