我m trying to insert / update a very long sql, tried to format to string, but won对MySQL表格产生任何影响：
import MySQLdb
db = MySQLdb.connect(host=host, user=user, passwd=passwd, db=db)
cur = db.cursor()
str1 = 'x'
str2 = 'y'

""" % (str1, str2)
cur.execute("INSERT INTO `wp_options`(`option_id`, `option_name`, `option_value`, `autoload`) VALUES ('450', 'theme_mods_flatsome', '%s', 'yes')" % s)
db.commit()
也尝试用（）代替＆＃34;＆＃34;＆＃34;和＆＃34;＆＃34;＆＃34;，但没有。
没有错误消息，似乎查询没问题，但不会改变任何内容。
制作了一个新文件，尝试从文件中加载字符串
with open('config') as f:
query = f.read()
cur.execute("UPDATE wp_options SET option_value = '%s' WHERE option_id = 450" % query)
答案 0 :(得分：0)
问题在于编码，我有几个小时的头痛原因，但我回来分享决议：
str = unicode（str，errors ='ignore'）
