Subject [jira] [Commented] (HIVE-10924) add support for MERGE statement
Date Fri, 07 Jul 2017 21:22:00 GMT

Carter Shanklin commented on HIVE-10924:
----------------------------------------

[~Absolutesantaja] that's a good call out, can you file a new sub-task for tracking purposes?

The good news, possibly, is that Hive already does support insert column lists for the ordinary
insert statement. As I understand it the MERGE statement is just re-written into other statements
so this may not be difficult to achieve.
