Edward Capriolo commented on HIVE-494:
--------------------------------------
I think any user will realize that '$1' can change. In the end i think hive
should be more dynamic somewhat like pig. Imagine something like this:
create table x stored by dynamichandler;
select $1 , $2 from x (inputformat=textinputformat, inpath=/x/y/z);
We are close to this now because Navis added the ability to specify per query
table properties.
What is, or what is not in the SQL spec should not be our metric, we can
already do amazing things that SQL can't so I want to keep innovating. As long
as something does not produce an ambiguity in the language I see no harm in it.

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