In MYSQL, what is the command used to reload the grant tables?

In MYSQL, what is the command used to reload the grant tables?

  • PRIVILEGES RELOAD;
  • FLUSH PRIVILEGES;
  • RELOAD GRANT;
  • UPDATE PRIVILEGES; 

 

EXPLANATION


Privileges assigned through GRANT option do not need FLUSH PRIVILEGES to take effect - MySQL server will notice these changes and reload the grant tables immediately.
From MySQL documentation:
If you modify the grant tables directly using statements such as INSERT, UPDATE, or DELETE, your changes have no effect on privilege checking until you either restart the server or tell it to reload the tables. If you change the grant tables directly but forget to reload them, your changes have no effect until you restart the server. This may leave you wondering why your changes seem to make no difference! 


To tell the server to reload the grant tables, perform a flush-privileges operation. This can be done by issuing a FLUSH
PRIVILEGES statement or by executing a mysqladmin flush-privileges or mysqladmin reload command.
