Jason Dere resolved HIVE-2558.
------------------------------
Resolution: Fixed
Fix Version/s: 0.12.0
> Timestamp comparisons don't work
> --------------------------------
>
> Key: HIVE-2558
> URL: https://issues.apache.org/jira/browse/HIVE-2558
> Project: Hive
> Issue Type: Bug
> Reporter: Robert Surówka
> Fix For: 0.12.0
>
>
> I may be missing something, but:
> After performing:
> create table rrt (r timestamp);
> insert into table rrt select '1970-01-01 00:00:01' from src limit 1;
> Following queries give undesirable results:
> select * from rrt where r in ('1970-01-01 00:00:01');
> select * from rrt where r in (0);
> select * from rrt where r = 0;
> select * from rrt where r = '1970-01-01 00:00:01';
> At least for the first two, the reason may be the lack of timestamp in
> numericTypes Map from FunctionRegistry.java (591) . Yet whether we really
> want to have a linear hierarchy of primitive types in the end, is another
> question.
