Program Syntax Help Needed

Hello -

I am new to PostgreSQL and trying to create a program to update a table, but I am getting syntax errors.

Here is my program:

-------------------------------------------------------------
-- Import copy_note data
CREATE OR REPLACE FUNCTION add_copy_notes() RETURNS integer AS '
DECLARE
copynote RECORD;
BEGIN;
FOR copynote IN SELECT * FROM asset.copy ac
JOIN biblio.call_number cn
ON (ac.call_number = cn.id)
JOIN biblio.record_entry b
ON (cn.record = b.id)
JOIN staging_item_notes in
ON (b.id = in.bibkey)
WHERE in.bibkey != 0
LOOP
INSERT INTO asset.copy_note (owning_copy, creator, create_date, pub, title, value)
SELECT DISTINCT ac.id AS owning_copy,
1 AS creator,
CAST 04-26-2010::DATE AS create_date,
TRUE AS pub,
''Copy Note'' AS title,
in.value AS value
FROM staging_item_notes in;
END LOOP;
RETURN;
END;
' LANGUAGE SQL;
SELECT * FROM add_copy_notes();
-- COMMIT;
-- ROLLBACK;
-------------------------------------------------------------

and I get the following error messages:

psql:generate_notes.sql:26: ERROR: syntax error at or near "RECORD"
LINE 3: copy RECORD;
^
psql:generate_notes.sql:27: ERROR: function add_copy_notes() does not exist
LINE 1: SELECT * FROM add_copy_notes();
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.

I'm trying to retrieve one record at a time from the table asset.copy, which includes elements with different data types, in order to update asset.copy_note.
Any help would be appreciated. Thanks.
