查了一下文档，这是11gR2 sqlplus中新添的内容：http://docs.oracle.com/cd/E11882_01/server.112/e16604/ch_twelve040.htm

SET EXITC[OMMIT] {ON | OFF}

Specifies whether the default EXIT behavior is COMMIT or ROLLBACK.

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.

Table 12-5 shows the exit action associated with combinations of SET commands (AUTOCOMMIT & EXITCOMMIT) and the EXIT command.

默认是set exitcommit on;
当我改成set exitcommit off:
SQL> select * from tt;


        ID
----------
         3


SQL> insert into tt values(0);
