Get to your mysql directory in a command prompt.

I type in

mysql -u root mysql

Then,

grant all privileges on *.* to username@localhost idenitified by 'password' with grant option;

Replace username and password with your user/pass for MySQL.

From there, type in "use <database>;"

Replace <database> with the name of your database.

Then type in the query posted above. I use an older version of MySQL and am not sure if the 'mysql -u root mysql' will work anymore. If not, browse around for how you would do it.
