'Add Day to Timestamp

How do I add days to a timestamp? If my timestamp is 01-JAN-2011 11-09-05 and I add 2 days, I want 03-JAN-2011 11-09-05.

Solution 1:[1]

select '01-jan-2011 11-09-05' + interval '2' day

Solution 2:[2]

A completely Oracle-centric solution is to simply add 2 to the timestamp value as the default interval is days for Oracle dates/timestamps:

SELECT TO_TIMESTAMP('01-jan-2011 11-09-05','DD-Mon-YYYY HH24-MI-SS') + 2
  FROM dual;

Solution 3:[3]

In a similar case, I used:

SELECT TO_TIMESTAMP('01-jan-2011 11-09-05','DD-Mon-YYYY HH24-MI-SS') + NUMTODSINTERVAL(2, 'DAY')

Because, othewise, the expression is converted to DATE and precission is lost. See: NUMTODSINTERVAL documentation
