I have a "lot" table with 2 columns, with one of the column is current timestamp.
I try to return another custom fields, which its calculation is based on timestamp.
(For simplicity, I include only 1 field in following example)
CREATE OR REPLACE FUNCTION create_lot(text)
RETURNS lot AS
$BODY$DECLARE
configurationFile ALIAS FOR $1;
_lot lot;
BEGIN
INSERT INTO lot(configuration_file)
VALUES(configurationFile) RETURNING *, extract(epoch from timestamp) as timestampex INTO _lot;
return _lot;
END;$BODY$
LANGUAGE 'plpgsql' VOLATILE
COST 100;
ALTER FUNCTION create_lot(text) OWNER TO postgres;
I expect the table returns two field for a single row. 1 is configuration_file, 2nd is timestamp, 3rd is timestampex.
However, I only able to retrieve configuration_file and timestamp. How can I obtain timestampex too?
Thanks and Regards
