Hi Douglas,
Thanks for your promptly answer. Here is the "step by step":
CREATE TABLE test
(
description varchar(20),
picture lo
)
WITHOUT OIDS;
INSERT INTO test (description) VALUES ('1');
And then, the error : INSERT INTO test (description) VALUES ('1')
What I am trying to do is insert data only on the column description,
leaving the column picture null (because for this tuple there is no image).
Regards,
Rodrigo Carvalhaes
