I'm not too familiar, but the removal of select 42 is part of #6524, and I'm not confident if we can put that change here as well.

it seems that "select 42 from table where" is used only to form a complete sql sentence together with the where condtion. now we can evaluate the where condtion directly without this "select" sql sentence.
