Alexander Pivovarov commented on HIVE-9518: ------------------------------------------- Hi [~jdere] I know you implemented HIVE-9792 Support interval type in expressions/predicates recently. Very nice! Just curious does it implement MONTHS_BETWEEN functionality? Do you think MONTHS_BETWEEN UDF provides functionality which can not be achieved with interval type expressions? > Implement MONTHS_BETWEEN aligned with Oracle one > ------------------------------------------------ > > Key: HIVE-9518 > URL: https://issues.apache.org/jira/browse/HIVE-9518 > Project: Hive > Issue Type: Bug > Reporter: Xiaobing Zhou > Assignee: Xiaobing Zhou > Attachments: HIVE-9518.1.patch, HIVE-9518.2.patch, HIVE-9518.3.patch, > HIVE-9518.4.patch > > > This is used to track work to build 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
