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

I need to use large objects BUT I am having problemns... I instaled
PostgreSQL 8.0.3 windows version with lo module.
first, I created the table below:
CREATE TABLE test
(
description varchar(20),
picture lo
)
WITHOUT OIDS;
After trying to make one insert without value for the lo I get the
error below:
INSERT INTO test VALUES (1);
ERROR: invalid input syntax for integer: ""
This means you're trying to insert an integer value into the
"description" column, which is text. It has nothing to do with large
objects.
To insert an LO into a database, you do the following:
BEGIN a transaction
Call lo_create() to make a new large object. The return value is the
OID of the LO, which you will need later.
Call lo_write() and lo_close() to put data into the LO
Insert the OID you got from lo_create() in the referencing column
("picture", in your case)
COMMIT the transaction
It's a little annoying but that's how it works.
