mysql table garbled code

MySQL table garbled characters are one of the common problems, mainly manifested as garbled characters in the database or garbled characters in the query results.

The main reason for this problem is that the encoding of MySQL and the encoding of your application are not consistent, causing the data to be damaged during transmission. For example, your application might use UTF-8 encoding, but MySQL uses Latin1 encoding by default.

The following are some ways to solve this problem:

1. Modify the encoding of MySQL

In MySQL, you can modify the encoding by modifying the configuration file . In the my.cnf file, add the following two lines of configuration:

character-set-server=utf8
collation-server=utf8_general_ci```

如果您已经有了一个存在的数据库，可以通过下面的命令修改相应的表的编码：

```ALTER TABLE tableName CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;```

2. 修改应用程序的编码

如果您的应用程序和 MySQL 的编码不一致，可以尝试将应用程序的编码修改为与 MySQL 一致。比如，如果 MySQL 使用 UTF-8 编码，那么应用程序也应该使用 UTF-8 编码。

可以通过修改配置文件之类的方法来达到这个目的。具体的方法取决于您的应用程序。

3. 使用工具检查 MySQL 的编码

可以使用工具来检查 MySQL 的编码，比如 MySQL Workbench。这个工具可以帮助您查看表的编码、修改表的编码等操作。

4. 导入数据时指定编码

在导入数据的过程中，可以通过指定编码来解决这个问题。比如，您可以使用下面的命令导入数据：

CHARACTER SET utf8
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '
'
IGNORE 1 ROWS;`

This command specifies that the encoding used in the data file is UTF-8.

Summary:

MySQL Table garbled characters are one of the common problems in database development, mainly caused by inconsistent coding. This problem can be solved through the above methods. The specific method depends on your application and MySQL configuration. When designing the database, It is recommended to use UTF-8 encoding, because this is an encoding method that supports multiple languages ​​and can avoid many encoding problems.
