Should I be using table inheritance in this scenario?
Table "contact" has name, address, phone, email, etc. columns.
Table "staff" inherits from "contact because it has many columns in
common with "contact".
But I want to query staff and get a list of staff-- and omit non-staff
contacts. The ONLY directive only works down the inheritance tree, so I
would have to do (something like) this to get a list of staff only:
SELECT staff.whatever
FROM staff, pg_class
WHERE staff.tableoid = pg_class.oid AND pg_class.relname = 'staff'
This strikes me as kinda funny and maybe I should not have inherited
staff from contact to begin with? Not really up to speed on the whole
object-relational concept yet. :-)
