Experts,

Yes, you can do it explicitly or you can let Oracle handle the conversion for you:

declare
l_date date;
begin
select systimestamp into l_date from dual;
dbms_output.put_line(l_date);
dbms_output.put_line(trunc(l_date));
dbms_output.put_line(to_char(l_date,'MM/DD/YYYY'));
end;

If you have a varchar2 variable, then you can format the date/timestamp as you like:

DECLARE
l_date VARCHAR2(4096);
BEGIN
SELECT to_char(SYSTIMESTAMP,'DD-MON-RR') INTO l_date FROM dual;
dbms_output.put_line(l_date);
END;

Experts,

The date is coming in as part of a Select statement.  ie

Select memberid
       ,member,lname
       ,member_fname
       ,member_dob
From members.

Can member_dob be formatted in this type of query.  Some languages you can use datepart(d, member_dob)

OK. What exactly do you want to display?

Run the following query and let me know if anything looks like it:

WITH members AS
(
 SELECT
    1 memberid
   ,'UNCLEAR' member_lname
   ,'MORINIA' member_fname
   ,SYSDATE - INTERVAL '20' YEAR member_dob
  FROM dual
)
SELECT memberid
       ,member_lname
       ,member_fname
       ,to_char(member_dob,'MM/DD/YYYY') member_dob_1
       ,to_char(member_dob,'DD-MON-RR') member_dob_2
       ,EXTRACT(DAY FROM member_dob) member_dob_day
       ,EXTRACT(MONTH FROM member_dob) member_dob_month
       ,EXTRACT(YEAR FROM member_dob) member_dob_year
FROM members
