使用SQLAlchemy和Python将本地数据文件加载到MySQL数据库中

Question

我将尝试使用SQLAlchemy中的LOAD LOCAL DATA INFILE命令将批量文件上传至我的服务器。我已经编辑了/etc/mysql/my.conf文件，并在[mysql]和[mysqld]下添加了local-infile==1，但是当我运行程序时，出现了下面的错误信息。相关的代码行如下：

    Traceback (most recent call last):
  File "main.py", line 48, in <module>
    con.execute(sql)
  File "/Users/eoddata/venv/lib/python2.7/site-packages/sqlalchemy/engine/base.py", line 906, in execute
    return self._execute_text(object, multiparams, params)
  File "/Users/eoddata/venv/lib/python2.7/site-packages/sqlalchemy/engine/base.py", line 1054, in _execute_text
    statement, parameters

    self.errorhandler(self, exc, value)
  File "/Users/eoddata/venv/lib/python2.7/site-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler
    raise errorclass, errorvalue
sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError) (1148, 'The used command is not allowed with 
this MySQL version') [SQL: "LOAD DATA LOCAL
 INFILE 'stocks/AMEX_20150420.txt' INTO TABLE database.new_table\n                    
FIELDS TERMINATED BY ',' (Symbol,@Date,Open,High,Low,Close,Volume)\n                    
SET Date = STR_TO_DATE(@Date,'%%Y%%m%%d');"]

我通过文档进行了一些研究，但无法找到解决此错误的方法。使用python的MySQLdb（来自pip install MySQL-Python）将允许我传递一个local-infile参数。我找不到SQLAlchemy中的等效方法。需要任何帮助。

编辑：我整夜都在解决这个问题，但仍然没有取得任何进展 - 很多死胡同。有什么想法吗？

谢谢，Jared

您应将local_infile=1添加到连接字符串中。

SQLALCHEMY_DATABASE_URI = "mysql://user:pass@localhost/dbname?charset=utf8&local_infile=1"
