Hi
How would one goabout creating an empty record (for use in relations).
Eg
create table product(
productid SERIAL NOT NULL,
product TEXT,
PRIMARY KEY(productid)
);
create table product_billable(
productid INT4 NOT NULL,
billaddress TEXT,
PRIMARY KEY (productid),
FOREIGN KEY (productid) REFERENES product(productid) ON DELETE CASCADE
);
All fields except for the primary key can be NULL.
What if I wanted to add a new billable product but I have not got a name
for it yet?
So how could I insert a new record in product that can be used in
product_billable?
I have tried INSERT INTO product() VALUES(); but as expected it did not
work.
All help appreciated
Best regards
