MS Access : cannot join on Memo,OLE,od Hyperlink object

[shaguna.dhall@intrasphere.com]

I have a MS Access Db,which I migrated to Oracle.I created linking with
oracle tables in my Access db.Both MS Access and Oracle db have unicode
characters.
I need to test whether the data is same in both databases.

I'm using Access db and linked tables of Oracle.I perform join on the
tables to get records. When I run the query on Access db to compare,I
get the following error

"cannot join on Memo,OLE,od Hyperlink object"

How do i test the data between Access and linked tables in Oracle?

Any suggestions would be helpful.

Thanks
