Hi,
Try creating a function that returns either 0 or 1 depending on whether or not the value is numeric and then handle the result accordingly.
Something like:
CREATE OR REPLACE FUNCTION IS_NUMBER(p_string IN VARCHAR2) RETURN NUMBER
AS
vNUMBER NUMBER;
BEGIN
SELECT TO_NUMBER(p_string) INTO vNUMBER FROM DUAL;
RETURN 1;
EXCEPTION WHEN OTHERS THEN
RETURN 0;
END;Then create a PL/SQL process that loops through your data. Something like:
BEGIN
FOR x IN 1..APEX_APPLICATION.G_F01.COUNT
LOOP
  IF IS_NUMBER(APEX_APPLICATION.G_F01(x)) = 0 THEN
   ... do something if the value is not numeric ...
  END IF;
END LOOP;
END;Andy
