-----------------------------
Attachment: HIVE-494.D12153.1.patch
navis requested code review of "HIVE-494 [jira] Select columns by index instead
of name".
Reviewers: JIRA
HIVE-494 Select columns by index instead of name
SELECT mytable[0], mytable[2] 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.
