Xiaobing Zhou updated HIVE-9518:
--------------------------------
Description:
This is used to track work to build a Oracle like months_between. Here's
semantics:
MONTHS_BETWEEN returns number of months between dates date1 and date2. If date1
is later than date2, then the result is positive. If date1 is earlier than
date2, then the result is negative. If date1 and date2 are either the same days
of the month or both last days of months, then the result is always an integer.
Otherwise Oracle Database calculates the fractional portion of the result based
on a 31-day month and considers the difference in time components date1 and
date2.
> Implement MONTHS_BETWEEN aligned with Oracle one
