Add query derivation for delete queries [DATAJDBC-551]

[spring-projects-issues]

trafficstars

rod2j opened DATAJDBC-551 and commented

Derived delete/removeByXxx queries work as expected for return type void but fail when return type is long/Long or List<entity type>, where it should return the number of records or the list of entities actually deleted:

instead I get 

org.springframework.aop.AopInvocationException: Null return value from advice does not match primitive return type for: public abstract long 

it also appears the generated SQL query is actually a SELECT instead of a DELETE whenever the derived delete query has a non void return type.

Created a sample project on github to recreate the issue: data-jdbc-issue-551

 

When it executes this statement:

 

long nbDeletedFR = repo.deleteByNameAndCountryCode("Grenoble", "FR");

The following exception is thrown:

I also failed to get deletes to work so worked around that with custom sqls

Mark Paluch commented

Thanks for reporting the issue. Derived delete queries are not yet supported

rod2j commented

Thanks for the information Mark. What about adding a dedicated table in JDBC repositories chapter about which features of spring data common are not implemented? Because of the structure of the documentation, when we access the reference doc from a spring data project Web page, many of the chapters are actually documenting spring data common, and one can easily assume that these features are actually implemented if nothing says the contrary.

That said I really like Spring Data Jdbc.

I submitted PR.

Rob Maskell commented

I tried a derived delete query with a void return type and this exception was thrown

org.springframework.data.mapping.model.MappingInstantiationException: Failed to instantiate void using constructor NO_CONSTRUCTOR with arguments 

The repository method signature was

void deleteByEventId(Long eventId);

[DavidTsengOperva]

This is such a surprise that warrants more attention in documentation. The example given in documentation gave the impression that deleteBy and removeBy are derived delete query that just work but not. It took me a long time in debugging.
