Edward Capriolo commented on HIVE-494:
--------------------------------------
I think we should also support negative numbers to query from the right end
like awk's $NF
> 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
