Multi-language support tips in MySQL

MySQL is an open source relational database management system that is widely used in data storage and management of various applications. In today's internationalization trend, multi-language support has become a must-have feature for many applications. However, MySQL does not directly provide multi-language-related features, so developers need to take some tricks to implement multi-language support.

This article will introduce some multi-language support techniques in MySQL, aiming to help developers implement multi-language support functions more easily.

1. Language code of field

In MySQL, the common practice is to add a language code prefix to each multi-language field. For example, there is a "name" field that contains multiple language versions of the name. You can add prefixes to the names of different language versions, such as "en_name" for English names and "zh_name" for Chinese names.

The advantage of this method is that it is easy to select the language in the code, and it is also convenient to maintain and manage multi-language data.

2. Multi-language support for database tables

Another common way to implement multi-language functionality is to use multi-language support for database tables. The benefit of this approach is that multilingual data can be easily organized together, rather than storing fields for each language separately.

To implement multi-language support for database tables, two tables need to be created. The first table is used to store the primary key ID and public fields of all language versions, such as timestamp, creator, title and content, etc. The second table contains the text fields and language codes for each language version.

By using a JOIN query, you can match the multilingual fields of the first table with the language codes of the second table to facilitate finding and displaying specific language versions in your application.

3. Storing multilingual text as a single string

Storing multilingual text as a single string is another way to implement multilingual functionality. This method joins different language versions of text together, separates them with some delimiter, and then stores them in a single field.

This method requires good delimiter strategies and language code conventions to ensure that the text can be parsed and displayed correctly when displayed.

4. Use JSON format to store multilingual content

For MySQL 5.7 and later, you can use JSON format to store multilingual content. The advantage of this method is that it supports complex nested structures, is easy to use, and is easy to maintain and update.

When using JSON format to store multilingual text, a JSON field is required to store the text content and language code. For example:

{
"en": "Hello, world!",
"zh": "Hello, world!"
}

When needed , you can use MySQL's JSON functions to extract language-specific content from a JSON field.

Summary

MySQL does not directly support multi-language functionality, but developers can use the above techniques to achieve multi-language support. Each method has its advantages and disadvantages, and it is up to the developer to weigh the pros and cons and choose the one that best suits the application.

Using a long-term support version (LTS) of MySQL ensures more efficient performance and better stability when using these techniques.
