问题描述
我正在解析 json 数据并尝试将一些 json 数据存储到 Mysql 数据库中.我目前收到以下 unicode 错误.我的问题是我应该如何处理这个问题.
I am parsing json data and trying to store some of the json data into Mysql database. I am currently getting following unicode error. My question is how should I handle this.
- 我是否应该从数据库端处理它，如果是这样，我该如何修改我的表?
- 我应该从 python 方面处理它吗?
这是我的表结构
CREATE TABLE yahoo_questions (
question_id varchar(40) NOT NULL,
question_subj varbinary(255),
question_content varbinary(255),
question_userId varchar(40) NOT NULL,
question_timestamp varchar(40),
category_id varbinary(20) NOT NULL,
category_name varchar(40) NOT NULL,
choosen_answer varbinary(255),
choosen_userId varchar(40),
choosen_usernick varchar(40),
choosen_ans_timestamp varchar(40),
UNIQUE (question_id)
);
通过python代码插入时出错:
Error While inserting via python code:

在运行查询之前我还做了什么我在 mysql SET character_set_client = utf8
What I also did prior to running the query I execute the following on mysql SET character_set_client = utf8
这就是 mysql 变量的样子:
And this how the mysql variables looks like:
mysql> SHOW variables LIKE '%character_set%';
+--------------------------+--------------------------------------------------------+
| Variable_name | Value |
+--------------------------+--------------------------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/local/mysql-5.5.10-osx10.6-x86_64/share/charsets/ |

推荐答案
我认为您的 MYSQLdb python 库不知道它应该编码为 utf8，而是编码为默认的 python 系统定义字符集 latin1.
I think that your MYSQLdb python library doesn't know it's supposed to encode to utf8, and is encoding to the default python system-defined charset latin1.
当您 connect() 到您的数据库时，传递 charset='utf8' 参数.这也应该使手动 SET NAMES 或 SET character_set_client 变得不必要.
When you connect() to your database, pass the charset='utf8' parameter. This should also make a manual SET NAMES or SET character_set_client unnecessary.
