fetch cursor into id, set_values .... -> problem - Mailing list pgsql-novice

Hello,
I get this error
#error 1
ERROR:  syntax error at or near "," at character 525
LINE 15: FETCH curs INTO id, set_values;
                           ^
from this function

drop function sx(varchar) ;
CREATE OR REPLACE FUNCTION sx( varchar ) RETURNS varchar AS $$
DECLARE
str_in ALIAS FOR $1;
id RECORD  ;
set_values RECORD ;
curs CURSOR FOR SELECT id, set_values FROM constraint_table;
BEGIN
OPEN curs;
FETCH curs INTO id, set_values;
IF (str_in = set_values ) THEN RETURN 1::bit(2);
ELSE RETURN 0::bit(2);
END IF;
END;
$$  LANGUAGE plpgsql;


isn't it correct to declare as type RECORD  ?

thanks,
joseph.
