LOAD DATA LOCAL INFILE sqlalchemy和python到mysql db

2023年10月2日 327次阅读

我正在尝试使用sqlalchemy的LOAD LOCAL DATA INFILE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[mysqld]下包含local-infile == 1,但是当我运行程序时我得到了这个回溯.

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

    context)

    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');"]

我从文档中做了一些研究,但找不到修复此错误的方法.使用python MySQLdb(来自pip install MySQL-Python)将允许我传入本地infile参数.我在SQLAlchemy中找不到相应的东西.任何帮助表示赞赏.

编辑：我整晚都在努力,仍然没有取得任何进展 – 很多死路一条.有任何想法吗？

谢谢,贾里德

最佳答案 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"
