Hi, sorry to bother you, but do you know what the following problem could
be? I am trying to
create some relationships with the following SQL code in Postgresql:
ALTER TABLE dialup_account
ADD CONSTRAINT customer_dialup_account
FOREIGN KEY (
customer_id
)
REFERENCES customer (
customer_id
);
I get the following error message:
ERROR: parser: parse error at or near "constraint"
Any ideas?
