In pgadmin3 I'm tring to add auto_inc column like this
ALTER TABLE public.modems ADD COLUMN id serial;
But get this error :
NOTICE: ALTER TABLE will create implicit sequence "modems_id_seq" for "serial" column "modems.id"
ERROR: adding columns with defaults is not implemented
HINT: Add the column, then use ALTER TABLE SET DEFAULT.
How to add auto_inc fields... thanx
PS. Can I use OID column for primary/foreign functionality, or it
has some restriction ...i mean i may not use auto_inc field ?
