-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 So I'm not a libpq programmer. I would guess that you might have access to the OID of the row and you could SELECT the id using that. Here's another thought, define a function something like this: CREATE FUNCTION foo(VARCHAR) RETURNS INTEGER AS ' DECLARE N ALIAS FOR $1; I INTEGER; BEGIN -- maybe you have to select the value into the int I := nextval(''''idseq''''); INSERT INTO .... RETURN I; END; ' LANGUAGE 'plpgsql' WITH (isstrict); Also, there is a datatype named 'name'. You'll be happier if you rename your "name" column to something else like "username". Joshua b.
