Eric Lomore commented on PHOENIX-3264:
--------------------------------------

Hi Julian- Thanks that makes sense. I've looked into this more, and attempted 
use of the SqlToRelConverter as well. But, to instantiate these objects/classes 
you need a lot of different objects (SqlValidator in particular) that as far as 
I can tell this method wouldn't have access to at runtime. 
Are we sure that this is the right approach or might we need to use/create a 
different utility for this?

> Phoenix supports TRUE and FALSE as boolean literals, but perhaps Calcite 
> doesn't? Looks like this is leading to a fair number of failures.
