Creating Views in Hive with parameter

Question

I have a table that contains rows belonging to various dates. I want to CREATE A VIEW which should give me the data based on the date

CREATE VIEW newusers
A         


        

Answer 1

In the hive script, just replace the date with a variable:

CREATE VIEW newusers
AS
SELECT DISTINCT T1.uuid
FROM user_visit T1
WHERE T1.firstSeen="${hiveconf:date}";

Then give that variable a value when invoking hive:

hive --hiveconf date=20140522 -f 'create_newusers_view.hql'

Or just set it from within hive:

set date=20140522;
