Hi all,
I want to add some common columns to all of my tables. One way I
think would be to add a super table that contains the common columns
to all tables. But is there a way to add a super table to existing
tables for them to inherit from?
Thanks!
Jun
as long as the parent and child has the same table struct, yes.
use:
alter table child inherit newparent;

err... sorry, let me fix that: the parent must have a common subset of all the children. (The children can have extras the parent does not, but not visa versa)
