我试图在一个python文件中发送两个sql（select和update）。但仍然有错误

cursor = cnx.cursor()
  query = "select id, mail from `candidats`; UPDATE candidats SET statusmail=1 "
  results = cursor.execute(query, multi=True)
  for cur in results:
    print('cursor:', cur)
    print('result:', cur.fetchall())
  cursor.close()
  cnx.close()

获取此错误：

mysql.connector.errors.InterfaceError: No result set to fetch from
