Export a view

Export a view

Today, my colleague asked me how to export a view. I rarely saw such a fine-grained requirement and tested it decisively:

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

Unexpectedly, I am not disappointed at all, because there is no view parameter during help reading. Continue:

[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, Oracle and/or its affiliates.  All rights reserved.
