How are the predefined administrative roles in MySQL Workbench different from the roles created with SQL statements?

Predefined administrative roles are stored in the mysql database, while roles created with SQL statements are not.

Predefined administrative roles can be manipulated using SQL statements, while roles created with SQL statements cannot.

Predefined administrative roles allow for quick assignment of privileges, while roles created with SQL statements require manual assignment of privileges.

Predefined administrative roles are limited to specific databases, while roles created with SQL statements apply to all databases on the server.
