Simple patch, but was very useful for me to implement query generator for random-forest.

Select columns by index instead of name
---------------------------------------

Key: HIVE-494
URL: https://issues.apache.org/jira/browse/HIVE-494
Project: Hive
Issue Type: Wish
Components: Clients, Query Processor
Reporter: Adam Kramer
Priority: Minor

Attachments: HIVE-494.D1641.1.patch


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.
