code: def execute(self, statement, *args, **kwargs):
          
          with self.engine.connect() as conn:
              s = sqlalchemy.sql.text(statement)
              return conn.execute(s, **kwargs)
docs: This convenience method will execute the query passed in as is.  For
          more complex functionality you may want to use the sqlalchemy engine
          directly, but this serves as an example implementation.
  
          :param select_query: SQL statement to execute that will identify the
              resultset of interest.
