SET
SET option = value, ...
The SET query allows you to set a number of options
both on your client and on the server.The most common uses of the SET OPTION query are
changing your password,
SET PASSWORD = PASSWORD('new_password')and
changing another user’s password (if you have appropriate access privileges).
SET PASSWORD FOR user = PASSWORD('new_password')For a complete list of the options
that may be SET, refer to the MySQL
Reference Manual.
