The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "log1.py", line 326, in <module>
    p.map(main_loop, logs_list)
  File "/usr/lib/python3.5/multiprocessing/pool.py", line 260, in map
    return self._map_async(func, iterable, mapstar, chunksize).get()
  File "/usr/lib/python3.5/multiprocessing/pool.py", line 608, in get
    raise self._value
pymysql.err.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 '' at line 1")

Answer 1

看你的报错是SQL语句出错，应该是你换行符引起的
sql语句换行建议用三个引号来，如

create_table = """
    sql语句
"""

Answer 2

变量名: log_pattern_obj 没有定义, 检查下是不是打错字母或者忘记定义了
