修改mysql数据库的默认编码方式_MySQL
修改mysql数据库的默认编码方式
修改my.ini文件
加上
default-character-set=gb2312
设定数据库字符集
alter database da_name default character set ‘charset’
1)设置数据库编码 /etc/my.cnf
[mysqld]
default-character-set=gbk
…
[client]
default-character-set=gbk
---------------------------------------
2)按字符集导出
$mysqldump -u root -p dbname –default-character-set=gbk > a.sql;
3)查看SQL文件的编码
[root@localhost gethtml]# file a.sql
a.sql: UTF-8 Unicode …
[root@localhost gethtml]# iconv -f utf-8 -t gbk a.sql > a2.sql
[root@localhost gethtml]# file a2.sql
a2.sql: Non-ISO extended-ASCII English text 这时已经是gbk的编码了
3)导入
查看数据库服务和客户端字符集
mysql> status;
Server characterset: gbk
Db characterset: gbk
Client characterset: latin1
Conn. characterset: latin1
mysql> set names ‘gbk’; //这样
mysql> status;
Server characterset: gbk
Db characterset: gbk
Client characterset: gbk
Conn. characterset: gbk
这时才能导数据mysql> source a.sql;
———————————————————————————-
单独设置某个数据库:alter database testdb character set utf8;
查看mysql支持的编码:
show character set;
查看系统的字符集和排序方式的设定可以通过下面的两条命令:
mysql> SHOW VARIABLES LIKE ”character_set_%”;
LINUX 如下:
1)导出数据[root@www.cnscn.org ~]$ mysqldump -u root -p dbname –default-character-set=gbk > base_user.sql;
2)查看导出的sql文件的编码
[root@www.cnscn.org ~]$ file base_user.sql
base_user.sql: UTF-8 Unicode text, with very long lines
3)转成要用的编码[root@www.cnscn.org ~]$ iconv -f utf-8 -t gbk base_user.sql >base_user_gbk.sql
4)连接数据库并查看当前库的编码
[root@www.cnscn.org ~]$ mysql -uroot
mysql> use testdb;
mysql> status;
Server characterset: latin1
Db characterset: gbk
Client characterset: latin1
Conn. characterset: latin1
5)设置成需要的编码mysql>set names ‘gbk’;
6)查看现在的编码
mysql> status;
Server characterset: latin1
Db characterset: gbk
Client characterset: gbk
Conn. characterset: gbk
7)导入我们转换成gbk后的文件mysql> source base_user_gbk.sql;

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

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'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

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.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
