Re: autoincrement???

Hi,
try the serial type. This will create a sequence and add a default value to
collumn, which will auto increment your value.

Like:
CREATE TABLE address (
address_id serial PRIMARY KEY ,
street VARCHAR(40),
zipcode INT,
city VARCHAR(40),
country VARCHAR(40)
);

INSERT INTO address VALUES('mainstreet 12', 85253, 'munich', 'Germany');

CoL:
col(at)econet(dot)hu
