用 Python 希腊字母写入 (Oracle) SQL 文件不起作用

Question

I'm trying to write Greek letters to file with ".sql" extension. But the result in the file are not correct.

The code in Python:

with open('test.sql', 'w', encoding='utf-8') as test_file:
    test_file.write('DH5α\n')

In the SQL file I get:

DH5α

Any way I can solve this?

OS is windows

Thanks.

Answer 1

From the cx_Oracle documentation Character Sets and Globalization make sure your connections are opened with the right character set.

import cx_Oracle
connection = cx_Oracle.connect(connectString, encoding="US-ASCII", nencoding="UTF-8")

Note that with cx_Oracle 8, the defaults changed to be "UTF-8".

Answer 2

正如评论中所写，问题出在 sql-developer 本身，它默认不使用 utf-8 编码。
