I'm looking to add a column to my database with not null and a default value:
vk=> alter table msg_owner add column user_optional_fields varchar(255) NOT NULL default ''; ERROR: Adding columns with defaults is not implemented. Add the column, then use ALTER TABLE SET DEFAULT. vk=> alter table msg_owner add column user_optional_fields varchar(255) NOT NULL ; ERROR: Adding NOT NULL columns is not implemented. Add the column, then use ALTER TABLE ADD CONSTRAINT. Ok, so we can succeed with this: ALTER TABLE msg_owner ADD COLUMN user_optional_fields VARCHAR(255); ALTER TABLE msg_owner ALTER user_optional_fields SET DEFAULT ''; UPDATE msg_owner SET user_optional_fields = ''; Now my problem is I cannot find any syntax for ALTER TABLE ADD CONSTRAINT to put a NOT NULL constraint on a column. Can someone help me here? I'm using Postgres 7.2.1 on FreeBSD 4.6. Thanks. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vivek Khera, Ph.D. Khera Communications, Inc.
