退出并重新进入，并验证表内容是否存在。
SQL> exit
……
SQL> select * from session_test; no rows selected SQL>
接下来创建事务级别的临时表
SQL> create global temporary table transaction_test on commit delete rows as select * from test.test; Table created.
SQL> select * from transaction_test; no rows selected
接下来添加数据到事务临时表 transaction_test
SQL> insert into transaction_test select * from test.test;
4 rows created.
SQL> select * from transaction_test;
ID NAME
---------- ----------
0 orcl
1 orcl
3 orcl
2 orcl
如上我们将 test.test 表的内容插入到了 transaction_test 表中，然后直接查询，能查到刚刚插入的数据。
接下来提交，并查询。（提交相当于提交事务，也就是一个事务的结束）
SQL> select * from transaction_test;
ID NAME
---------- ----------
0 orcl
1 orcl
3 orcl
2 orcl
SQL> commit;
Commit complete.
SQL> select * from transaction_test;
no rows selected
由此可见
