Re: NEED HELP COPY TO DYNAMIC OUTPUT FILE

Thanks guys for the quick reply, i've solve it with using EXECUTE :P

Here is my fully code :

-- Function: etiket_ho.fn_settlement(integer)

-- DROP FUNCTION etiket_ho.fn_settlement(integer);

CREATE OR REPLACE FUNCTION etiket_ho.fn_settlement(integer)
RETURNS void AS
$BODY$
DECLARE
i integer;
k integer;
STATEMENT TEXT;
v_settlement TEXT;
rec_max ALIAS FOR $1;
rec_cur CURSOR FOR
SELECT ('0220' || station_id || lpad(trans_id,5,'00000') || lpad(settlement_id,5,'00000') || flazz_card_pan || flazz_card_expired || trans_date || updated_flazz_card_balance || amount_payment || completion_code || psam_id || psam_trans_no || psam_random_no || psam_crytogram || flazz_card_cryptogram || flazz_card_trans_no || flazz_card_debit_certificate || merchant_id || terminal_id || trn || flazz_version || flazz_trac_expired || reserved) AS val_settlement FROM etiket_ho.t_settlement ORDER BY station_id, trans_id;
BEGIN
CREATE TEMPORARY TABLE log_settlement (log TEXT);
OPEN rec_cur;
i:=0; j:=0; k:=0;
LOOP
FETCH rec_cur INTO v_settlement;
EXIT WHEN NOT FOUND;
INSERT INTO log_settlement(log) VALUES(v_settlement);
IF (i=rec_max) then
STATEMENT:= 'copy log_settlement to ''/usr/proj/' || replace( current_date, '-' , '') || lpad(text(k),5,'00000') || '.txt''';
EXECUTE (STATEMENT);
TRUNCATE TABLE log_settlement;
i:=0;
ELSE
i:=i+1;
END IF;
k:=k+1;
END LOOP;
CLOSE rec_cur;
DROP TABLE log_settlement;
RETURN;
END
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION etiket_ho.fn_settlement(integer) OWNER TO postgres;
