title: can I perform a query inside of JPA entity to get back a single column
body: <p>I have a dumb question.  It would be great if this could be done, but I am not holding my breath.  </p>
  
  <p>I need a single column from a table linked to my JPA entity to be a collection in said JPA entity.  Is there any way, that I can just get back that column alone that is related to that entity, instead of having to get back an entire table (which could be very costly?)</p>
  
  <p>Can I perform a query inside that JPA entity that will be performed and loaded eagerly into a collection?  </p>
  
  <p>I am trying to avoid having to make several calls to the database by just executing a couple of queries.  </p>
  
  <p>What are your thoughts on this?</p>
