Unicode 问题与 Pandas 和 SQLAlchemy 使用 Z30162ED78B6C10F7314FZ 数据库11F2FC440C2

Question

我正在尝试使用 pandas 读取 csv 文件并将其写入 oracle 数据库

import pandas as pd
import sqlalchmey types, create_engine

df = pd.read_csv("abc.csv")
df.dtypes
Name object
CName object
price float64

df.head(2)
Name    CName  price
Gary    ALS    13.0
John    Ülka   19.9

engine = create_engine('oracle://+ xxx + xxx + 'connection string')
connection = engine.connect()
df.to_sql(name='test-tbl', con=connection, index=False, if_exists='append')

 File "/apps/anaconda/4.6.14/envs/TST/lib/python3.6/site-packages/sqlalchemy/engine/base.py", line 1468, in _handle_dbapi_exception
    util.reraise(*exc_info)
  File "/apps/anaconda/4.6.14/envs/TST/lib/python3.6/site-packages/sqlalchemy/util/compat.py", line 154, in reraise
    raise value
  File "/apps/anaconda/4.6.14/envs/TST/lib/python3.6/site-packages/sqlalchemy/engine/base.py", line 1224, in _execute_context
    cursor, statement, parameters, context
  File "/apps/anaconda/4.6.14/envs/TST/lib/python3.6/site-packages/sqlalchemy/dialects/oracle/cx_oracle.py", line 1080, in do_executemany
    cursor.executemany(statement, parameters)
UnicodeEncodeError: 'ascii' codec can't encode character '\xea' in position 23: ordinal not in range(128)

目前我正在使用python3.6测试上面的代码，看到上面的错误。有没有人可以帮助解决这个问题？

package 版本：pandas-1.0.3 cx_oracle-6.4.1 sqlalchemy-1.3.5

UTF-8 中的 CSV 文件格式

（复制评论以作为解决方案的可见性）

解决方案是使用类似的东西：

import cx_Oracle
e = create_engine(
    "oracle+cx_oracle://un:pw@connstr...",
    connect_args={
        "encoding": "UTF-8",
        "nencoding": "UTF-8"
    }
)
