      Description

      When inserting NULL values to a server which doesn't support BULK statements NULL values are not inserted correctly.

      Example:

      import mariadb
       
      conn=mariadb.connect(user="georg", database="test")
      cursor=conn.cursor()
      cursor.execute("CREATE TEMPORARY TABLE ind1 (a int, b int default 2,c int)")
      vals = [(1,4,3),(None, 2, 3)]
      cursor.executemany("INSERT INTO ind1 VALUES (?,?,?)", vals)
      cursor.execute("SELECT a, b, c FROM ind1")
      row= cursor.fetchall()
      print(row)
