MariaDB: Find Users in MariaDB
Question:Is there a query to run in MariaDB that will return all Users created?
Answer: In MariaDB, there is a system table called mysql.user. Since MariaDB is a fork of MySQL, the system table is still called mysql.user for compatibility.
You can run a query against this system table that returns all of the Users that have been created in MariaDB as well as information about these Users.
To retrieve all Users in MariaDB, you can execute the following SQL statement:
SELECT User FROM mysql.user;
The mysql.user table contains the following columns:
