Count and Exists projection for @Query about spring-data HOT 5 CLOSED

Can't you just do the following:

// Count for collection
@Query("RETURN COUNT(@@collection)")
// Count for a query
@Query("RETURN COUNT(FOR doc IN ... FILTER ... RETURN doc)")

// Exists for a specific document
@Query("RETURN DOCUMENT(@id) != NULL")
// Exists for a query
@Query("RETURN COUNT(FOR doc IN ... FILTER ... RETURN doc) > 0")

from spring-data.

@christian-lechner Nope. I can't get these queries return an integer nor a boolean:

Caused by: com.arangodb.velocypack.exception.VPackValueTypeException: Expecting type ARRAY or OBJECT or STRING

from spring-data.

@christian-lechner @lihanyu23 Yep, this is a bug. We missed to add the types we are able to deserialize in ArangoAqlQuery.

from spring-data.

Perfect!
@mpv1989: instead of new byte[] {}.getClass() you can also write byte[].class

from spring-data.

Fixed in 2.1.0
