Hive table load time from timestamp


Hive table load time from timestamp

New Contributor

Hello all, i have a hive table with a column of datatype timestamp. The source table from which I am loading just have time(not date like timestamp) . I just want to load the time. But due to timestampdatatype it takes a default date. How i can write a query which just takes time from source table. I need the data type to remain as timestamp


Re: Hive table load time from timestamp


It is not clear if you're using two tables - a source and a destination table, or you simply want to select the time element from timestamp datatype from a single table.

Extracting the time from a timestamp involves extracting the different components in the timestamp, for example:

select concat(hour(current_timestamp()), ':', minute(current_timestamp()), ':', second(current_timestamp()));
