Supposed I have the query:
SELECT names, color
FROM my_dataset
WHERE date='2013-07-18'
And this outputs:
John 0
David 1
Mary 0
Bill 0
Joe 2
The problem is that the 'color' column are Intergers. Is it possible to feed in a key/feature map somewhere so the output can be (0=GREEN, 1=BLUE, 3=RED) instead??
