title: DB Unit should ignore order of rows
body: <p>Is there a way telling DB-Unit to ignore the order in which rows should be compared? My problem is, that I do not know in which order the rows will be written to the database, but DB-Unit forces me to give an ordered list.</p>
  
  <p>What I want dbunit to do is: </p>
  
  <ul>
  <li>check that number of rows in database and expected dataset match (Solved: Works out of the box</li>
  <li>check whether each rows will be found only once in the result-set. (NOT SOLVED)</li>
  </ul>
  
  <p>Any ideas?</p>
