The columns in the select list match the parameter names so you're
selecting the parameters, not the columns in example1.  The query
is effectively:

   for red in select NULL, NULL, NULL from example1 loop

The code should work if you qualify the columns:

   for red in select e.id, e.name1, e.value1 from example1 e loop
