title: Subsonic Delete multiple records
body: <p>I have a table which has a two fields, userid and degreeid. A user can have multiple degreeds in this table. When a user select their degree I want to delete any degree id already in the database but un-selected by user. How should do it? I try to use something like this with no luck.</p>
  
  <p>repo.DeleteMany(x=>x.MeetingAttendeeUserID==userID &amp;&amp; x.EducationDegreeID userDegreeList)</p>
  
  <p>Thanks,
  Lewis</p>
