MySQL: Explain VERSION() in MySQL.

 

In MySQL, the VERSION() function is used to retrieve the version number of the MySQL server that you are currently connected to. It returns a string representing the version of the MySQL server software.

The basic syntax of VERSION() is as follows:

sql
VERSION()

When you execute this function, it returns a string containing the version information for the MySQL server.

For example:

sql
SELECT VERSION();

This query will return a string like 8.0.26, indicating the version number of the MySQL server.

The version information is useful for various purposes, including checking compatibility with specific features or troubleshooting issues related to version-specific behavior. If you're using a MySQL client tool, it may also display the server version during the connection process.

It's important to note that the VERSION() function provides information about the MySQL server software itself, not the version of the MySQL protocol or any specific client library. Always ensure you are aware of the server version when working with MySQL to ensure compatibility with your queries and applications.
