推荐答案

您不能在Phoenix中这样做.

相反，您首先需要为现有的 Hbase/Phoenix 表创建一个视图，在您的情况下为"test_2"

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

因此您可以执行以下操作:

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
