查詢可在`select`從句中指定類的屬性，甚至可以調用SQL統計(aggregate)函數。 屬性或統計結果被認定為"標量(Scalar)"的結果（而不是持久(persistent state)的實體）。

```
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];
    .....
}
```
