hadoop - Hive UDF String to Date Convertion -

-

the hive contains table "sample" following data:

15-06-2015 15-06-2015 15-06-2015 15-06-2015 15-06-2015 15-06-2015 16-06-2015

using following query converting string type of data hive date format:

select to_date(from_unixtime(unix_timestamp(date,'dd-mm-yyyy'))) sample;

the output follows:

0   2014-12-28 1   2014-12-28 2   2014-12-28 3   2014-12-28 4   2014-12-28 5   2014-12-28 6   2014-12-28

the output differ expected output.

please suggest how expected output like:

2015-06-15 2015-06-15 2015-06-15 2015-06-15 2015-06-15 2015-06-15 2015-06-16

your problem hiveql case insensitive, second argument of unix_timestamp function, instead, case sensitive. right syntax query is:

select to_date(from_unixtime(unix_timestamp(date,'dd-mm-yyyy'))) sample;

in way, you'll expected result.
