Julian Hyde commented on PHOENIX-3264:
--------------------------------------
Yeah, you need to be in a particular environment (i.e. phase of statement
preparation) to use those things. That said, why not leave the constant as a
SqlLiteral, at least while it's in SqlOptionNode? The constructor of
SqlOptionNode is called from the parser, which is too early to have a validator
or sql-to-rel converter. But by the time you need the literal value, you'll
probably be in a validator anyway.
> Allow TRUE and FALSE to be used as literal constants

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