如果中間有語句發生錯誤就不一樣了，寫了一個測試的例子，看看對你有幫助沒有
drop table aatest;
create table aatest
(nid number,nname varchar2(16))
insert into aatest(nid,nname)values(1,'00');
commit;
create or replace procedure aatesta
as
begin
   update aatest set nname='step1' where nid=1;
   commit;
   update aatest set nname='step2' where nid=1;
   commit;
   update aatest set nname='step3_12345678910101010101' where nid=1;
   commit;
   exception when others then
     rollback;
end;
create or replace procedure aatestb
as
begin
   update aatest set nname='step1' where nid=1;
   update aatest set nname='step2' where nid=1;
   update aatest set nname='step3_12345678910101010101' where nid=1;
   commit;
   exception when others then
     rollback;
end;
