Maybe there's a neat way of doing this in the driver I'm not aware of, but usually this is left to the job of a higher level library or class you write yourself.

To shamelessly plug my own, Jdbi handles this nicely:

In database server, it has a default isolation level,  and if we want to use
a different one, we can easily do:

begin;
set transaction isolation level xx; 

commit; 

We can see that the isolation level is set at the transaction level.  However when I
check the API,  looks I can only set it at *connection* level via Connection.setTransactionIsolation(x);  If I want to rollback the original, I have
to remember to reset it after this transaction which would be boring in practice. 
What would be the best practice for this?
