You mean I can use autocommit = on and begin a transaction manually???
Is the implicit rollback to rollback all before ???

My situation is like this , can you help me :
  1.set autocommit = off ;
  2.for(i=0;i<len;i++){
      insert into test(c1,c2) values(i,'a');
      if dupkey error occur then
      update test set c2 = 'b';--error:rollback first???
      else {
         rollback and return;
      }
   }
  3.commit;

I want to do like this:
  1. set autocommit = off ;
  2. for(i=0;i<len;i++){
      savepoint sp;
      insert into test(c1,c2) values(i,'a');
      release savepoint sp;
      if dupkey error occur then
         rollback to sp;
      update test set c2 = 'b';
      else{
         rollback and return;
      }
   }
   3.commit;

Can I use another way to implenment this ? (don't use the savepoint)
thanks.
