Returning a numeric list

Question

We have an application that expects certain columns within our tables store a comma seperated list of numeric values. Our database however stores that information within lookup tables. To return that list I have opted for the below function within Oracle. My only issue though is I am hardcoding the table name(LKP_PROP_PRODSEG) and column names(PROPERTIESID and PRODSEGMENTID) for the cursor and there is more than one table so this solution of mine would mean a different function for each instance. How could I instead use function arguments for those values? Or is this the best avenue to be taking for the end goal?
CREATE TABLE LKP_PROP_PRODSEG
PROPERTIESID NUMBER DEFAULT 0 NOT NULL,
PRODSEGMENTID NUMBER DEFAULT 0 NOT NULL
INSERT INTO LKP_PROP_PRODSEG (PROPERTIESID, PRODSEGMENTID) VALUES (4, 1);
INSERT INTO LKP_PROP_PRODSEG (PROPERTIESID, PRODSEGMENTID) VALUES (4, 2);
INSERT INTO LKP_PROP_PRODSEG (PROPERTIESID, PRODSEGMENTID) VALUES (4, 3);
INSERT INTO LKP_PROP_PRODSEG (PROPERTIESID, PRODSEGMENTID) VALUES (4, 4);
CREATE OR REPLACE FUNCTION GETLKPPRODSEGLIST ( arg_propID IN NUMBER )
RETURN VARCHAR2
IS
idList VARCHAR2(4000);
CURSOR GETID IS SELECT PRODSEGMENTID FROM LKP_PROP_PRODSEG WHERE PROPERTIESID = arg_propID;
BEGIN
idList := null;
FOR i IN GETID LOOP
     IF idList IS null THEN
          idList := i.PRODSEGMENTID;
     ELSE
     idList := idList || ',' || i.PRODSEGMENTID;
     END IF;
END LOOP;
RETURN idList;
END;
SELECT GETLKPPRODSEGLIST(4) FROM dual;

Check out stragg at asktom.oracle.com.
SELECT stragg(prodsegmentid)
  FROM lkp_prop_prodseg
WHERE propertiesid = 4;However, it doesn't take care of the fact that you have to know what table your data is in.
Apparently Jens and Kamal posted a bit more promptly than I did...
