Unfortunately, there is no direct functionality in MySQL to drop users based on a regex pattern. However, you can achieve this by following these steps:

  1. Execute the following query to obtain a list of users that match the regex pattern: SELECT name FROM mysql.user WHERE name REGEXP 'your_regex_pattern';
  2. Iterate through the result set and generate DROP USER statements for each matching user.
  3. Execute the generated DROP USER statements to remove the users: DROP USER 'username1'@'localhost'; DROP USER 'username2'@'localhost'; ...

Note: Make sure to replace 'username1', 'username2', etc. with the actual usernames obtained from the previous step.

Caution: Dropping users should be done with extreme caution as it permanently removes the user and all associated privileges.
