I am but that is what actually want : to be able to add a column
to the first table and have the second to be added a coulumns
automatically.The target is realy simple :
i want to simplify management of the schema and thus be able to
manage only parantes - children should be managed aoutomagically
But the data is NOT the same!
Isn't it the inheretence is all about - to inherit?
