最有可能基于已使用ON COMMIT DELETE ROWSoption 创建的全局临时表（GTT）打开了游标。ORA-08103: object no longer exists错误的原因是commit语句之后紧随其后的delete语句。这是一个简单的示例：
sql> declare
2 type t_recs is table of number;
3 l_cur sys_refcursor; -- our cursor
4 l_rec t_recs;
5
6 begin
7
8 -- populating a global temporary table GTT1 with sample data
9 insert into GTT1(col)
10 select level
11 from dual
12 connect by level <= 1000;
13
14 open l_cur -- open a cursor based on data from GTT1
15 for select col
16 from GTT1;
17
18 -- here goes delete statement
19 -- and
20 commit; <-- cause of the error. After committing all data from GTT1 will be
21 -- deleted and when we try to fetch from the cursor
22 loop -- we'll face the ORA-08103 error
23 fetch l_cur -- attempt to fetch data which are long gone.
24 bulk collect into l_rec;
25 exit when l_cur%notfound;
26 end loop;
27
28 end;
29 /
ORA-08103: object no longer exists
ORA-06512: at line 24
带有on commit preserve rows语句的全局临时表的创建将允许从基于该表的游标中安全地获取数据，而不必担心会遇到ORA-08103:错误。
