So how is `ROLLBACK` in Oracle exception handler different from my `ROLLBACK`?
问题 How Oracle Database rollback to the beginning of the PL/SQL block, but not the earlier DML instructions (I think all this come under one single transaction). Because when I try to ROLLBACK creating an exception handler all the instructions until last COMMIT are rolled back. create table mytable (num int not null primary key); insert into mytable values(1); // My ROLLBACK, rollbacks to here. begin // Oracle exception handler rollbacks to here. insert into mytable values(3); begin insert into
