Обсуждение: Error when calling this function....

Am I wrong to assume that I can simply call the following function
with SELECT catalog_batch(); ?
Additionally, I am still unclear as to how I should handle the return
type for this function.  Is what I have ok?  Should the word Complete
in the return statement be quoted?


CREATE FUNCTION catalog_batch() RETURNS text AS '

    DECLARE
        mp3rec RECORD;
    BEGIN
        FOR mp3rec IN SELECT * FROM mp3catalog LOOP

        INSERT INTO album (title, media, path, release_date)
VALUES (mp3catalog.album, mp3catalog.audioformat, mp3catalog.path,
mp3catalog.year);

        INSERT INTO track (album_id, trk_no, trk_title, time,
genre, bitrate, channel, notes) VALUES (SELECT
currval("album_album_id_seq"), mp3catalog.track, mp3catalog.title,
mp3catalog.time, mp3catalog.genre, mp3catalog.bitrate,
mp3catalog.channels, mp3catalog.comment);

        INSERT INTO participant (name) VALUES (mp3catalog.artist);

        INSERT INTO performance (album_id, participant_id)
VALUES (SELECT currval("album_album_id_seq"), SELECT
currval("participant_participant_id_seq"));

        END LOOP;
        RETURN Complete;
    END;'

    LANGUAGE 'plpgsql';

recordings=> select catalog_batch();

You don't need the VALUES when you select ie:
INSERT INTO tbl (a,b) SELECT a,b FROM tbl2;
