python - LOAD DATA LOCAL INFILE sqlalchemy 和 python 到 mysql 数据库

Question

我正在尝试使用 LOAD LOCAL DATA INFILE 和 sqlalchemy 将批处理文件上传到我的服务器。我编辑了我的 /etc/mysql/my.conf 以在 [mysql] 和 下包含 local-infile == 1 [mysqld]，但我在运行程序时得到了这个回溯。

相关的代码行是:

    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

    cursor.execute(statement, parameters)
  File "/Users/eoddata/venv/lib/python2.7/site-packages/MySQLdb/cursors.py", line 205, in execute
    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');"]

我已经根据文档进行了一些研究，但找不到修复此错误的方法。使用 python MySQLdb(来自 pip install MySQL-Python)将允许我传入一个 local-infile 参数。我在 SQLAlchemy 中找不到等效项。感谢您的帮助。

编辑:我整晚都在做这件事，但仍然没有取得任何进展——有很多死胡同。有什么想法吗？

谢谢，贾里德

您应该将 local_infile=1 添加到连接字符串。

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