Subject [jira] Updated: (HIVE-31) Hive: support CREATE TABLE xxx SELECT yyy.* FROM yyy
Date Tue, 29 Sep 2009 18:42:18 GMT

Ning Zhang updated HIVE-31:

    Attachment: HIVE-31.patch

Attaching HIVE-31.patch. 

This patch implements the CTAS feature:

1) The select statement could be any query we support right now.
2) The created table and and source tables could have different SerDe and/or Storage formats.
3) the schema of the created table is detected from the select statement. User don't need
to (and should not) specify that.

1) Created table does not support partition now. There is another work on automatic partitioning
for insert statement. That will solve this problem.
2) Create table could not be an external table.
