12c datapump new features - part 3 - VIEWS_AS_TABLES

Nice new feature this one - allows extracting of a view definition and it's data as if it is a table.

First we connect and create a simple view

[oracle@server-name]:ED12G:[/oracle/diag/rdbms/orcl/ED12G/trace]# export TWO_TASK=//localhost:1525/test.e-ssi.net
[oracle@server-name]:ED12G:[/oracle/diag/rdbms/orcl/ED12G/trace]# sqlplus test/test

SQL> create view example as select * from session_roles;

View created.

SQL> exit

Now we extract that using the new parameter

[oracle@server-name]:ED12G:[/oracle/diag/rdbms/orcl/ED12G/trace]# expdp test/test views_as_tables=example directory=test dumpfile=example.dmp

Export: Release 12.1.0.1.0 - Production on Tue Jul 23 15:01:43 2013

Now we drop the view and import it back in as a table

[oracle@server-name]:ED12G:[/oracle/diag/rdbms/orcl/ED12G/trace]# sqlplus test/test

Now check all looks OK

[oracle@server-name]:ED12G:[/oracle/diag/rdbms/orcl/ED12G/trace]# sqlplus test/test
