The following example deletes the order with ID *1000* including all its items:

```java
CqnDelete delete = Delete.from("bookshop.Orders").matching(singletonMap("OrderNo", 1000));
long deleteCount = service.run(delete).rowCount();
long deleteCount = service.run(Delete.from("bookshop.Orders").byId(1000)).rowCount();
```

::: tip
To disable cascade delete for a specific Delete statement, add a `cascade.delete` hint(#hana-hints) with value `false`.

With CDS [views](../../cds/cdl#views-projections) you can derive new entities from existing ones, for example to rename or exclude certain elements, or to add [virtual elements](../../cds/cdl#virtual-elements-in-views) for specific use cases.
