Una sirena tiene las mismas probabilidades de arreglar tus problemas de permisos, la diferencia es que la gente continúa creyendo en el mito de FLUSH PRIVILEGES.Cada vez que alguien escribe un tutorial o solución a un problema relacionado con la creación de una nueva cuentas de usuario o la provisión de diferentes privilegios veo la sugerencia de utilizar FLUSH PRIVILEGES.

Your MySQL connection id is 15
Server version: 5.1.41-log MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
