Hi everybody, I need your help. I have a hierarchy of tables, and other table that has a foreign key with the top table of the hierarchy, can I insert a value into the "other" table where the value it reference is not on the parent table? (it's in one of its child) My best regards. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
