Sorry, I meant to write instead of
final RelDataType type =
typeFactory.createTypeWithNullability(fieldList.get(0).getType(), true);
in my previous email.
I think it would make sense to change the hardcoded value but I didn't try
to see if there are test failures after the change neither I know
Actually the types is derived this way
final RelDataType type =
typeFactory.createTypeWithNullability(fieldList.get(0).getType(), *true*);

Hi Gelbana,

instead of
final RelData
