Remove the DROP table privilege for a MySQL user

If you want to remove the DROP permission for a MySQL user, you can use the REVOKE statement. Assuming you want to revoke the DROP permission for a user named username on a database named database_name, you can do it with the following steps:

  1. Connect to MySQL as a user with administrative privileges. For example:

bash

                      mysql -u root -p

Replace root with the appropriate MySQL administrative user, and you'll be prompted to enter the password.

  Once you are connected to MySQL, run the REVOKE statement to remove the DROP permission:

sql

                      REVOKE DROP ON database_name.* FROM 'username'@'localhost';

This statement revokes the DROP privilege for the specified user on the specified database. Adjust the database_name, username, and 'localhost' values according to your setup.

  After revoking the permission, you need to run the FLUSH PRIVILEGES statement to apply the changes:

sql

FLUSH PRIVILEGES;

This command reloads the grant tables and makes the changes take effect immediately.

Remember to replace database_name and username with your actual database name and user, respectively. Also, ensure you have the necessary administrative privileges to execute these statements.
