Apache Phoenix Create statement as select (from)

问题

I am trying to create a new table from an existing structure in Phoenix. Is there a CREATE as Select statement in Phoenix. I am trying and they are failing with the below exception.

Any suggestions here are welcome. Thanks in advance.

 CREATE TABLE TEST AS (SELECT * FROM TEST_2 WHERE 1 =2);

You can't do like this in Phoenix.

Instead you need to create a view of a existing Hbase/Phoenix table first which in your case is 'test_2'

So you can do something like this:

CREATE VIEW test_view (a VARCHAR, b VARCHAR) AS
SELECT * FROM test_2
WHERE 1 = 2 ;  // some condition
