MYSQL DELETE USER FROM MYSQL USER HOW TO
Deleting a User: In Reviewīy learning how to control your MySQL database users, you learn how to better manage your databases. However, the next time they attempt to log in, they will be unable to. After the instance is closed, the user will be deleted from the grant tables.The changes the user makes in that last instance would still be valid. Also, if the user is currently using an instance of MySQL while you are in the process of deleting the user, the instance will not close until the user closes it. Things to Keep in Mindĭeleting a user does not delete the databases or objects the user created or worked on. You can specify hostnames or only list the username so that all instances of the username are deleted. To do this, simply list the users at the end of the DROP USER statement and separate them with commas: DROP USER IF EXISTS user, user You can also remove more than one user at a time. When just a user is listed, the command will default to using a wildcard in the place of a hostname, thus signalling that all hostnames should be affected by the command: DROP USER Removing More than One User at a Time For example, if you executed the following, all “joe” usernames would be deleted: DROP USER joe This would look something like this: DROP USER IF EXISTS you don’t specify a hostname and just list the user, all users with that username would be deleted, regardless of hostname. The user can also be specified by hostname, if you want to limit where the user can connect from. However, if the user does not exist, you will receive an error. You can also run the command as: DROP USER user The IF EXISTS portion of the command keeps MySQL from throwing an error if the user doesn’t exist. Replace user with the username that you want to delete. he DROP USER statement looks something like this: DROP USER IF EXISTS user Without any information in the grant table, users will not be able to gain access. A user’s information needs to be stored in the grant tables so that the database can grant the user access. This command removes a user by deleting their information from the grant tables within the database. You can remove a user by using the DROP USER command.

If this is the case, you can either switch to another user that has the privileges (if you have more than one user designated to you) or ask your admin for privileges. If you do not have this privilege, you will not be able to delete another user. When deleting a MySQL user, you must have the global create user or delete privilege for the database. The user will be unable to log back into the database or make changes. Deleting a user from your MySQL database will remove the user and all of the user’s privileges. Unlike the process of creating a user, where you have to add permissions, deleting a user only requires you to enter the command and the username.
