mysql编码、数据表编码查看和修改总结1,查看自己安装的mysql的编码
2、查看Mysql支持的编码
3、查看数据库编码
4、查看数据表编码(show create table user \G;)
5、修改my.ini文件来修改编码:加上default-character-set=字符集(utf8.gbk.gb2312等)
6、命令行修改:alter database da_name default character set 'charset' ;或 set names 'charset';或alter database testdb character set utf8;
8、查看数据库服务和客户端字符集:
9、Linux系统下的修改:
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;

MySQL is suitable for beginners because it is simple to install, powerful and easy to manage data. 1. Simple installation and configuration, suitable for a variety of operating systems. 2. Support basic operations such as creating databases and tables, inserting, querying, updating and deleting data. 3. Provide advanced functions such as JOIN operations and subqueries. 4. Performance can be improved through indexing, query optimization and table partitioning. 5. Support backup, recovery and security measures to ensure data security and consistency.

Create a database using Navicat Premium: Connect to the database server and enter the connection parameters. Right-click on the server and select Create Database. Enter the name of the new database and the specified character set and collation. Connect to the new database and create the table in the Object Browser. Right-click on the table and select Insert Data to insert the data.

Navicat itself does not store the database password, and can only retrieve the encrypted password. Solution: 1. Check the password manager; 2. Check Navicat's "Remember Password" function; 3. Reset the database password; 4. Contact the database administrator.

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.

Navicat for MariaDB cannot view the database password directly because the password is stored in encrypted form. To ensure the database security, there are three ways to reset your password: reset your password through Navicat and set a complex password. View the configuration file (not recommended, high risk). Use system command line tools (not recommended, you need to be proficient in command line tools).

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.

You can create a new MySQL connection in Navicat by following the steps: Open the application and select New Connection (Ctrl N). Select "MySQL" as the connection type. Enter the hostname/IP address, port, username, and password. (Optional) Configure advanced options. Save the connection and enter the connection name.

Steps to perform SQL in Navicat: Connect to the database. Create a SQL Editor window. Write SQL queries or scripts. Click the Run button to execute a query or script. View the results (if the query is executed).
