Github user liufengdb commented on the issue: https://github.com/apache/spark/pull/20557 There may be some spark JDBC/ODBC drivers need to parse the returned results to get all the columns. We should avoid making changes on the returned "schema" from the server side. You can fix the issue on the client side.
