Instead of exit client and enter again, just type \r (reconnect)
and you have a new session.

Just a little note:

sometimes, if you are in command line session, you will not see the change
of the dynamic variable unless you logout and in again,
so in case you change the value of a dynamic variable but still the "show
variables" shows you the old value, dont panic!
exit mysql client and enter again.

Aloha!
