For Parquet, there is no need to create a basic view of the table (see Filtering External Parquet Data From a Foreign Table) because:
  • Parquet data already uses column names rather than payload record names. Column names are case insensitive, unlike the payload record names for CSV and JSON.
  • Parquet columns already have a data type, so you do not need a view to provide data typing.
