Importing selective data using impdp

Question

I have an entire DB to be imported as a dump into my own. I want to exclude data out of certain tables(mostly because they are huge in size and not useful). I cannot entirely exclude those tables since I need the table object per se(minus the data) and will have to re create them in my schema if I do so. Also in the absence of those table objects , various other foreign constraints defined on other tables will also fail to be imported and will need to be redefined.So I need to exclude just the data from certain tables.I want data from all other tables though.

Is there a set of parameters for impdp that can help me do so?

Answer 1

I would make two runs at it: The first I would import metadata only:

impdp ... CONTENT=METADATA_ONLY

The second would include the data only for the tables I was interested in:

impdp ... CONTENT=DATA_ONLY TABLES=table1,table2...

Answer 2

Definitely make 2 runs. One to create all the table objects, but instead of using tables in the second impdp run, use the exclude

impdp ... Content=data_only exclude=TABLE:"IN ('table1', 'table2')"

The other way works, but this way you only have to list the tables you don't want versus all that you want.
