Setting session characteristics would set it for session, but
I guess he want to set transaction isolation level for a transaction
in this case??
# begin;
# set transaction isolation level serializable;
# show variable;
NOTICE: TRANSACTION ISOLATION LEVEL is SERIALIZABLE
SHOW VARIABLE
(Don't forget to set isolation level each transaction that needs serializable
level isolation.)
