Phabricator updated HIVE-494:

    Attachment: HIVE-494.D1641.1.patch

navis requested code review of "HIVE-494 [jira] Select columns by index instead of name".
Reviewers: JIRA

  DPAL-732 Select columns by index instead of name

  SELECT mytable<span class="error">[0]</span>, mytable<span class="error">[2]</span>
FROM some_table_name mytable;

  ...should return the first and third columns, respectively, from mytable regardless of their
column names.

  The need for "names" specifically is kind of silly when they just get translated into numbers
anyway.
