mysql 无法插入中文
MySQL数据库 默认编码已经是 utf8 了, default-character-set = utf8,可是向数据库中表中插入中文时,却老是出现 ....\xB5\xA5\xD1\xA1 for column...这样的错误,经过查阅网上类型的错误后,发现一个很奇妙的现象,接下来我们就来开始介绍。 一、在安装数
MySQL数据库默认编码已经是utf8了, default-character-set = utf8,可是向数据库中表中插入中文时,却老是出现 ....\xB5\xA5\xD1\xA1 for column...这样的错误,经过查阅网上类型的错误后,发现一个很奇妙的现象,接下来我们就来开始介绍。
一、在安装数据库时就设定字符集编码为utf8的环境下
1.在当前字符集编码为:
- Server characterset: utf8
- Db characterset: utf8
- Client characterset: utf8
- Conn. characterset: utf8
下创建数据库:
(1)插入中文数据,操作不能成功。
(2)修改字符集编码为:
- Server characterset: utf8
- Db characterset: utf8
- Client characterset: gbk
- Conn. characterset: gbk
插入中文数据,显示正常。
二、在安装数据库时就设定字符集编码为gbk的环境下
1.当前字符集编码是:
- Server characterset: gbk
- Db characterset: gbk
- Client characterset: gbk
- Conn. characterset: gbk
下创建数据,插入中文数据,操作正常,显示正常。
2.当前字符集编码为utf8:
- Server characterset: gbk
- Db characterset: utf8
- Client characterset: utf8
- Conn. characterset: utf8
3.当前字符集编码为utf8:
- Server characterset: gbk
- Db characterset: gbk
- Client characterset: utf8
- Conn. characterset: utf8
插入中文数据,操作不能执行。
结论:要想能向数据库正常插入中文,必须满足以下条件:
1.要把字符集设定为能支持中文的gbk或则utf8;
2.把数据库的Client Characterset和Conn. Characterset的字符集都设定为gbk;
根据上面的提示 ,我更改了:
- SET character_set_client=gbk;
- SET character_set_connection=gbk;
之后再尝试想数据库插入中文,这时没有出错,能插入可是查询出来是乱码。
最后再更改;
- SET character_set_results=gbk;
这样之后,所有的问题都解决了,能正常插入也能正常显示了。
另附查看字符集命令
5.查看字符集设置
mysql> show variables like 'collation_%';
mysql> show variables like 'character_set_%';
修改字符集
mysql> set character_set_client=utf8;
mysql> set character_set_connection=utf8;
mysql> set character_set_database=utf8;
mysql> set character_set_results=utf8;
mysql> set character_set_server=utf8;
mysql> set character_set_system=utf8;
mysql> set collation_connection=utf8;
mysql> set collation_database=utf8;
mysql> set collation_server=utf8;

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

Building an SQL database involves 10 steps: selecting DBMS; installing DBMS; creating a database; creating a table; inserting data; retrieving data; updating data; deleting data; managing users; backing up the database.
