This looks pretty good and thanks for rebasing it on the current master.

In order to merge this we need a proper set of unit tests ensuring the right kind of SQL in generated.
The following cases should be covered:

  • deleting an aggregate with at least two level reference, i.e. root->child->grandchild
  • similar as above, but with one level replaced by an embedded entity.
  • deleting an aggregate by a direct attribute
  • deleting an aggregate by an indirect attribute

We support Oracle's experimental R2DBC driver by providing a dialect including bind markers. Since the driver is not yet available from Maven Central and it requires module-path support for ServiceLoader discovery, we need to apply a few workarounds including absence check for our integration tests.

See #230

Make count assertions case-insensitive regarding the count column name. Add missing license headers. Support DatabaseContainer without a database name.

I'm surprised that this feature has not yet been implemented, even though the documentation says it is supported with examples.
https://docs.spring.io/spring-data/jdbc/docs/current/reference/html/#repositories.core-concepts

Is there any progress?
