Re: Large Object => invalid input syntax for integer: ""

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
