private boolean canRaiseInputset(Command command, Collection<ElementSymbol> bindings) {
  // check to see if this is query.
  if (!(command instanceof Query)) {
    return false;
  }
  
  Query query = (Query)command; 
  Criteria crit = query.getCriteria();
  
  if (crit != null && (query.getGroupBy() != null || query.getHaving() != null || query.getLimit() != null)) {
    return false;
  }
  //temporarily remove the criteria
  query.setCriteria(null);
  //just throw away order by
  query.setOrderBy(null);
  
  List<ElementSymbol> references = QueryUtil.getBindingsReferences(query, bindings);
  query.setCriteria(crit);
  
  //if there are any input set bindings in the rest of the command, don't convert
  return references.isEmpty();
}
