years. | |
As substracting two dates results in an INTERVAL you just have to specify it's kind (V2R3+):
select
(current_date - install_dt) year,
(current_date - install_dt) month,
(current_date - install_dt) year to month
But beware of the default precision of 2 and the maximum of 4, so maximum number of month is 9999.
For details look at the SQL manuals...
