DBUnit: Composite Unique Key

Trying to insert into a database table with DBunit however, since the table doesn't explisitly define a primary key. The table defines a unique composite key. DBunit fails while execution with a "org.dbunit.dataset.NoPrimaryKeyException"... googled on this one and came across the following helpful site - http://dbunit.wikidot.com/noprimarykeytable...

With reference to the sample provided on this site... the issue is that it only supports defining a single primary key field.......Similarly, how do we provide it with a composite key...

Please advise.

I've bumped on this question while having the same problem. Didn't find much resources about this so I decided to share what I eventually came up with. I've found some old post from 2005 (http://www.systemmobile.com/?p=102) which gave me the idea that worked. Take a look at the following code sample which shows how to do it for composite keys:

Hope that this helps (at least to someone who bumps as I did).
Edit: I wrote an article with more details as reminder on my blog. Here it is dbunit with composite primary keys

I agree. Here's the link: http://aspose.com/file-tools
