Mysql show users and privileges

Without any additional parameters, the SHOW GRANTS command lists the privileges granted to the current user account with which you have connected to the server. Sadly, there isn’t one for mysql SHOW USERS nor is there one for mysql LIST USERS. This is a little inconsistent when you consider that there are other commands such as SHOW DATABASES, SHOW VARIABLES, SHOW TABLES, SHOW GRANTS and others. SHOW GRANTS displays only the privileges granted explicitly to the named account.

Other privileges might be available to the account, but they are not displayed. For example, if an anonymous account exists, the named account might be able to use its privileges , but SHOW GRANTS will not display them. SHOW GRANTS requires the SELECT privilege for the mysql system database, except to display privileges and roles for the current user. The common_schema solution presented above aggregates data from user _ privileges and other tables to give you the full picture.


The privileges displayed include all static privileges , and all currently registered dynamic privileges. There are multiple types of privileges that can be granted to a user account. The most commonly used privileges are: ALL PRIVILEGES – Grants all privileges to a user account. CREATE – The user account is allowed to create databases and tables. You can also view all privileges for all users by querying the user_ privileges table.

Additionally, it would be great if it could also list only those with GRANT OPTION. My initial thought was to select User from mysql. That would result in a very long query. You may with a root user or as someone with the super user-level access.


And you need to keep it secure with you as it will come handy with many such tasks. MySQL show users : list all users. The SHOW GRANTS statement presents the grant of the current account in frames of active connection session. In addition, we use the SELECT grant statement to check the grants of other accounts. The authorization system’s functionality includes the ability to have anonymous users and to enable specific functions such as LOAD DATA INFILE and various administrative operations.


This opens the Users and Privileges screen on the Login tab. Also known as global privileges. For security reasons, it is generally better to create and handle data as specific users.

Backing up the user and privileges – as Create User and grant statements – using mysqlpump or pt-show-grants is much better than backing up the grant tables in mysql system database. It’s recommended to run either of the above commands in a scheduled job beside your normal backups. I want to verify permissions for all users (including root) from ANY IP. In Mysql , SHOW command is used to get the details of database users and their privileges.


Using this command we can show database and its tables and also table column, index and etc. But some of the SHOW commands will return limited information based on the access privileges.

Once you've created a mysql database you'll want to add users and give them rights over specific databases or tables. How can you view users ? This user should be able to add other users to the database it has privileges for.
