title: When use EF stored procedure to handle with breezejs, how to return error from SP to client side?
body: <p>I call a raiserror in the SP, expect it will be returned to client side in some way, just like when I add raiserror to a trigger on a table, but now I don't see the message returned</p>
  
  <p>"Message":"An error has occurred.","ExceptionMessage":"Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries."</p>
  
  <p>Any idea?</p>
