Can I do anything to prevent " auto rollback in a transaction when an error occurs "

In a transaction , if a sql command invite an error , all commands before this command will be rollbacked , and the transaction reset and restart.

For example:

 

BEGIN

insert  t1 values(1);

delete from t2

insert t1 values(2);

commit

 

if table t2 doesn't exist , "delete from t2" invites an error , and the insert will be rollbacked .

 

How can I prevent the rollback even when an error occurs ? Thanks
