> There is a known problem with Oracle's intervals:
> {code:sql}
> select to_date('2018/03/31', 'yyyy/mm/dd') + (INTERVAL '1' MONTH(2)) from dual
> {code}
> results in {{ORA-01839: date not valid for month specified error}}
> As an alternative, ADD_MONTHS function could be used . 
> {code:sql}
> select ADD_MONTHS(to_date('2018/03/31', 'yyyy/mm/dd'), 1) from dual
> {code}
> It is not defined in the functions spec how timestampadd with SQL_TSI_MONTH should behave in some cases but anyway no error should happen.
> Currently "interval" - inflicted Oracle errors are transmitted for timestampadd invocations.
