Shawn Weeks created HIVE-20012: ---------------------------------- Summary: Implement SQL Standard Date and Timestamp Functions Key: HIVE-20012 URL: https://issues.apache.org/jira/browse/HIVE-20012 Project: Hive Issue Type: New Feature Reporter: Shawn Weeks
I've looked around and haven't seen an existing ticket on this. Many times you need to convert from arbitrary string formats to a date or a timestamp. The current method using the unix_timestamp function doesn't support milliseconds and is a bit clunky. I propose we implement a to_date and to_timestamp function that behave like the following. It may also be useful for the to_timestamp function to behave like the existing to_date function and convert Hive's default timestamp string into an actual timestamp. {code:java} select to_date('01-01-2000','dd-MM-yyyy'); 2000-01-01 select to_timestamp('01-01-2000 13:00:00.000','dd-MM-yyyy HH:mm:ss.SSS') 2000-01-01 13:00:00.000{code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
