essentially projecting it as mask(cc, 0, 4) AS cc. Readers are NOT allowed to
project columns that are not listed and must apply transforms. If the
required-projection is not present or is empty, it means that no projection is
required and all columns can be read as-is.\nNote: That each column must have
only a single projection, meaning a column can be projected as-is or as a
transformed value, but not both.\n',
