I would really like to know how I can define a primary key in postgres.
The database is for a search engine. The table looks like this:
CREATE TABLE Homepages (
URL varchar(80),
PageName varchar(80),
UserName varchar(40),
Keywords varchar(255)
);
And I'd like to define the attibute URL as the primary key but I've
got no clue on how to do that. Anyone?
Thanks in advance,
