-----------------------------------
Summary: inconsistent results between year(), month(), day(), and
the actual values in formulas
Key: HIVE-9632
URL: https://issues.apache.org/jira/browse/HIVE-9632
Project: Hive
Issue Type: Bug
Components: CLI
Affects Versions: 0.14.0
Environment: CentOS 6.5, HDP 2.2
Reporter: Robert Miller
In wanting to create a date dimension value which would match our existing
database environment, I figured I would be able to do as I have done in the
past and use the following formula:
(year(date)*10000)+(month(date)*100)+day(date)
Given the date of 2015-01-09, the above formula should result in a value of
20150109. Instead, the resulting value is 20353515.
SELECT
> adjusted_activity_date_utc,
> year(adjusted_activity_date_utc),
> month(adjusted_activity_date_utc),
> day(adjusted_activity_date_utc),
>
(year(adjusted_activity_date_utc)*10000)+(month(adjusted_activity_date_utc)*100)+day(adjusted_activity_date_utc),
> (year(adjusted_activity_date_utc)*10000),
> (month(adjusted_activity_date_utc)*100),
> day(adjusted_activity_date_utc)
> from event_histories limit 5;
OK

Oddly enough, this works as expected when a specific date value is used for the
column.
I have tried this with partition and non-partition columns and found the result
to be the same.
SELECT
> adjusted_activity_date_utc,
> year(adjusted_activity_date_utc),
> month(adjusted_activity_date_utc),
> day(adjusted_activity_date_utc),
>
(year(adjusted_activity_date_utc)*10000)+(month(adjusted_activity_date_utc)*100)+day(adjusted_activity_date_utc),
> (year(adjusted_activity_date_utc)*10000),
> (month(adjusted_activity_date_utc)*100),
> day(adjusted_activity_date_utc)
> from event_histories
> where adjusted_activity_date_utc = '2015-01-09'
> limit 5;
OK
