How to use the CURRENT_USER() function in MySQL and MariaDB databases
In MySQL and MariaDB the CURRENT_USER() function is used to get the current combination of username and host for the database connection and return it as a string. The function requires no arguments and can be used directly in SQL statements or within SQL queries.
The function can be used to determine the current user connected to the database so that authentication and authorization logic can be implemented based on the user's identity. CURRENT_USER() can be used for monitoring or logging purposes to allow tracking of user activity within the database. The retrieved user information can also be used in conditional statements or queries to perform various actions based on the user's identity, such as assigning specific logic or permissions to different users or groups of users.
The returned username and host combination may depend on the specific authentication mechanisms used by database servers. For security reasons, the username can be an encrypted or obfuscated representation.
