Oracle 11gR2中SQL*Plus中的新设置exitcommit

--Oracle 11gR2中SQL*Plus中的新设置exitcommit

The default setting is ON, which means that work is committed on exit, whether you expected it to be committed or not.
Set EXITCOMMIT OFF to rollback work on exit.

--默认情况下exitcommit为ON状态
SCOTT@PROD1> show exitcommit
exitcommit ON

--创建表进行对比实验
SCOTT@PROD1> create table t (id number);

Table created.

--插入数据后直接exit退出，发现退出时完成了自动commit
SCOTT@PROD1> insert into t values (1);

1 row created.

SCOTT@PROD1> exit
