Question

What would be the best way to calculate one year expiry date from current date in oracle?
PS : Need to consider leap year.

Answer 1

select (sysdate + interval '1' year ) from dual

update (see Justin Cave’s comment)

select decode( to_char(sysdate, 'mmdd'), 
               '0229', 
               (sysdate-1) + interval '1' year, 
               (sysdate + interval '1' year ))
 from dual;
