Use of QUERY option in 9iRel2 Export utility

Question

Hi All,
Is it possible to use a query option to the export utility of the form below assuming I am exporting a table called test1:
query="(test1.col1,test1/col2) not in (select test2.col1,test2.col2 from test2)"
I am not sure if it is allowed to reference another table in the query clause, test2 in the example above....?
Thanks

Answer 1

I don't have a 9iR2 environment with me right now but this works on 10gR2. And I have no reason to believe that it would not work in 9iR2.
