Adding a Foreign key!
Started by Nonameover 24 years ago1 messagesgeneral
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.
