10.5.5. Scalar Results


Queries can specify a property of a class in the select clause. They can even call SQL aggregate functions. Properties or aggregates are considered "scalar" results and not entities in persistent state.
Iterator results = sess.createQuery(
        "select cat.color, min(cat.birthdate), count(cat) from Cat cat " +
        "group by cat.color")
        .list()
        .iterator();

while ( results.hasNext() ) {
    Object[] row = (Object[]) results.next();
    Color type = (Color) row[0];
    Date oldest = (Date) row[1];
    Integer count = (Integer) row[2];
    .....
}
