engine = sqlalchemy.create_engine('mysql+mysqlconnector://root:xxxxx@localhost:3306/test',
connect_args={'auth_plugin': 'mysql_native_password'})
connection = engine.connect()
with open(file_name) as csvfile:
reader = csv.DictReader(csvfile, delimiter='|')
insert_table = table(tbl_name,*[column(field) for field in reader.fieldnames])
insert_dict = [{k: None if v == NULL_FIELD_VALUE else v for k,v in row.items()} for row in reader]
