In this tutorial, you will learn how to show all users in MySQL Database. A common question most beginner MySQL users ask is how to show all users in MySQL? Most of them assume there is MySQL Show Users command, but there isn’t one. It’s frequently asked because there are other MySQL commands for displaying information about the database, for example, SHOW DATABASES will show out all the databases, SHOW TABLES will show all the tables in your MySQL database etc. It’s not unusual for people to assume that there should be a “SHOW USERS” command in MySQL. Well, there isn’t one. Luckily there’s a way to list all MySQL user accounts via the command line tool.

Once you are logged in to your Linux server, execute the following command to log in to MySQL database.

MySQL List Users1. Login to MySQL Server

Log in as root in MySQL using the following command:

## mysql -u root -p

2. MySQL Show Users

mysql show all usersWe’ll just to query the User table to show all MySQL Users with the following command:

 

 

 

SELECT User, Host, Password FROM mysql.user;

The list of all MySQL users should be similar like one below:

+------------------+--------------+--------------+
| user             | host         | password     |
+------------------+--------------+--------------+
| root             | localhost    | 37as%#8123fs |
| debian-test-user | localhost    | HmBEqPjC5Y   |
| johnsm           | localhost    |              |
| brian            | localhost    |              |
| root             | 111.111.111.1|              |
| guest            | %            |              |
| adrianr          | 10.11.12.13  | RFsgY6aiVg   |
+------------------+--------------+--------------+
7 rows in set (0.01 sec)

If you want to add more columns or exclude some, just edit the command with the columns you need. You may only need the names of the users, so you can use SELECT User FROM mysql.user;

mysql list all users3. Display Only Unique Usernames in MySQL Database

If you want to display only unique usernames that won’t be repeated in more rows, you can use SELECT DISTINCT User FROM mysql.user;, which should give you this output:

 

+------------------+
| user             | 
+------------------+
| root             | 
| debian-test-user | 
| johnsm           | 
| brian            | 
| guest            | 
| adrianr          | 
+------------------+
6 rows in set (0.01 sec)

mysql get list of users4. MySQL Users Information

To see all the fields in the mysql.user table containing user description, run the following MySQL command to query the database.

mysql> desc mysql.user;

The output will look similar to the one below:

mysql> desc mysql.user;
+------------------------+-----------------------------------+------+-----+-----------------------+-------+
