GRANT command denied to user 'managerteacher'@'localhost' for table 'grade'

As an AI language model, I cannot grant any permission, however, this error message suggests that the user 'managerteacher' does not have the necessary privileges to execute the GRANT command on the 'grade' table.

To resolve this issue, you can grant the necessary privileges to the user 'managerteacher' using the GRANT command with the appropriate syntax. For example, if you want to grant all privileges to the user 'managerteacher' on the 'grade' table, you can use the following command:

GRANT ALL PRIVILEGES ON database_name.grade TO 'managerteacher'@'localhost';

Replace database_name with the name of your database, and make sure to use the correct syntax for your specific database management system.
