How to convert a string to timestamp with milliseconds in Hive

Question

I have a string \'20141014123456789\' which represents a timestamp with milliseconds that I need to convert to a timestamp in Hive (0.13.0) without losing the milliseconds.

Answer 1

Let say you have a column 'birth_date' in your table which is in string format, you should use the following query to filter using birth_date

date_Format(birth_date, 'yyyy-MM-dd HH:mm:ssSSS')

You can use it in a query in the following way

select * from yourtable
where 
date_Format(birth_date, 'yyyy-MM-dd HH:mm:ssSSS') = '2019-04-16 07:12:59999';
