Get SQL from query

need to pass this dynamic where statement into a stored procedure to return data ( for performance reasons)

   Hi
I have the need to extract the sql from a  query into a string. I basically need to pass this  dynamic where statement into a stored procedure to return data ( for performance reasons)

  var p1 = FilterViewModel.FilterPredicate;
                ITypedEntityQuery query = EntityQuery.Create(entityType);

                if (p1 != null)
                {
                    query = query.Where(p1);
                }
