Hello everyone, I know that a Primary Key can be added to a table after it has been created, doing this... CREATE UNIQUE INDEX table_pkey ON table (atribute); Well I wonder if a Foreign Key can also be added after the table is already created, and what syntax does it follow. Thankyou in advance. Stay Safe & Happy. :* TankGirl ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
