python - 使用 Airflow MySqlOperator 时插入查询中的语法错误

Question

我正在使用 MySqlOperator 将 .csv 文件加载到 mysql 表(test1 有 2 个 int 列)中，但在插入时出现语法错误查询，下面是我正在尝试的代码

    for filename in os.listdir(path):
            if str(filename).endswith('.csv'):
                     csv_data = csv.reader(file(filename))
                     for row in csv_data:
                            sql1=("""insert into test1 values (%s,%s)""",row)
                            mysql_op = MySqlOperator(task_id='testop',
                                       sql=sql1,
                                       mysql_conn_id='hack5_id', owner='hack5',dag=dag)
                            mysql_op.run(start_date=datetime.now(), end_date=datetime(2018, 5, 21))

错误:

_mysql_exceptions.ProgrammingError: (1064, "You have an error in your SQL 
syntax; check the manual that corresponds to your MySQL server version for 
the right syntax to use near '%s,%s)' at line 1")

请帮我解决这个问题。

尝试运行以下命令:

    for filename in os.listdir(path):
        if str(filename).endswith('.csv'):
                 csv_data = csv.reader(file(filename))
                 for row in csv_data:
                        sql1="insert into test1 values ({})".format(",".join(row))
                        mysql_op = MySqlOperator(task_id='testop',
                                   sql=sql1,
                                   mysql_conn_id='hack5_id', owner='hack5',dag=dag)
                        mysql_op.run(start_date=datetime.now(), end_date=datetime(2018, 5, 21))
