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' ) ";

[oracle@rac1 log]$ expdp lm/lm directory=DATA_PUMP_DIR dumpfile=view.dmp logfile=view_exp.log parfile=par.par Export: Release 11.2.0.1.0 - Production on Thu Jan 21 02:07:04 2016 Copyright (c) 1982, 2009,  and/or its affiliates.  All rights reserved.
