precision and for char with the precision exceeding max length of Oracle.

> Priority: Major
>
> We're trying to cast a node to a varchar with something like this:
> {noformat}
> relBuilder.cast(node, SqlTypeName.VARCHAR)
> {noformat}
> And in Oracle SQL, this generates sql like
> {noformat}
> CAST(node AS VARCHAR){noformat}
> which is incorrect. Oracle can only have VARCHAR types with an explicit
> precision.
> Looking at the code, it _seems_ like this should work with Oracle, so I'm not
> really sure what's going on here
