导出某个view

今天同事问我，如何导出某一个view，我较少见这么细粒度的需求，果断测试一下：

[oracle@rac1 log]$ expdp xxx/xxx directory=DATA_PUMP_DIR dumpfile=view.dmp logfile=view_exp.log views=V_TEST
LRM-00101: unknown parameter name 'views'

意料之中，我一点都不失望，因为看help的时候，根本没有view这个参数。继续：

[oracle@rac1 log]$ vi par.par 
INCLUDE = VIEW: "in ( 'V_TEST' ) ";


<pre name="code" class="html">[oracle@rac1 log]$ expdp lm/lm directory=DATA_PUMP_DIR dumpfile=view.dmp logfile=view_exp.log parfile=par.par
