  11.     return false;
  12.   }
  13.   //temporarily remove the criteria
  14.   query.setCriteria(null);
  15.   //just throw away order by
  16.   query.setOrderBy(null);
  17.   
  18.   List<ElementSymbol> references = QueryUtil.getBindingsReferences(query, bindings);
  19.   query.setCriteria(crit);
  20.   
  21.   //if there are any input set bindings in the rest of the command, don't convert
  22.   return references.isEmpty();
