Question

我使用python shell并执行＆＃39; insert＆＃39; sql，它出现＆＃34;语法错误：语法无效＆＃34;，任何人都可以告诉我MySQL语句中的错误是什么？感谢

cursor.execute("insert into monitor_task (job_id, task_id, host, port, active, last_attempt_time, last_status last_message, last_success_time, last_metrics, last_metrics_raw) values (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)", [1L, 0, 'hh-hadoop-srv-ct01.bj', 11101, True, datetime.datetime(1970, 1, 1, 0, 0, tzinfo=<UTC>), 2, '', datetime.datetime(1970, 1, 1, 0, 0, tzinfo=<UTC>), '', ''])
  File "<console>", line 1

SyntaxError: invalid syntax

和desc表monitor_task：

mysql> desc monitor_task;

SyntaxError是一个Python错误。语法错误在datetime对象创建中：

datetime.datetime(1970, 1, 1, 0, 0, tzinfo=<UTC>)

tzinfo=<UTC>是Python语法错误：

$ python
Python 2.7.3 (default, Mar 13 2014, 11:03:55) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime
>>> datetime.datetime(1970, 1, 1, 0, 0, tzinfo=<UTC>)
  File "<stdin>", line 1
    datetime.datetime(1970, 1, 1, 0, 0, tzinfo=<UTC>)
                                               ^
SyntaxError: invalid syntax

You can find here如何提供有效的tzinfo参数。
