python - 编程错误 : You must not use 8-bit bytestrings

Question

我试图在 python 2.7(windows) 中运行以下命令，但出现错误:

ProgrammingError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit byte strings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings.

#!/usr/bin/python
# -*- encoding: utf-8-*-

import sqlite3;
db = sqlite3.connect('db.sqlite3')
cursor = db.cursor()
cursor.execute('INSERT INTO X(id,a,b) VALUES(?,?,?)', (999998,"ą---ź---ć---ó---ęĘ","ssf"))
cursor.execute('SELECT * FROM X where id = 999998')
for row in cursor:
    print row

db.commit()
db.close()

如何将这些字符串(“ąźć”= 波兰符号)插入到我的 sqlite 数据库中？

Answer 1

您可以遵循他们的建议:“只需将您的应用程序切换到 Unicode 字符串即可。”

cursor.execute(
    'INSERT INTO X(id,a,b) VALUES(?,?,?)',
    (999998,u"ą---ź---ć---ó---ęĘ","ssf"))

注意字符串文字前的 u。这使它成为一个 unicode 文字。
