Returning vertex and edge properties in one query - orientdb

Question

I'm working with OrientDb 3.0.1.
Assume the following schema:
CREATE CLASS Product EXTENDS V;
CREATE PROPERTY Product.number STRING (MANDATORY, NOTNULL);
CREATE CLASS Object3D EXTENDS V;
CREATE PROPERTY Object3D.path STRING (NOTNULL);
CREATE CLASS has_Object3D EXTENDS E;
CREATE PROPERTY has_Object3D.in LINK Object3D (MANDATORY, NOTNULL);
CREATE PROPERTY has_Object3D.out LINK V (MANDATORY, NOTNULL);
CREATE PROPERTY has_Object3D.translation EMBEDDEDLIST INTEGER (MANDATORY, NOTNULL);
And some data like:
INSERT INTO Product (number) VALUES
('1'), ('2'), ('3');
INSERT INTO Object3D (path) VALUES
("path1"), ("path2"), ("path3");
CREATE EDGE has_Object3D
FROM (SELECT FROM Product WHERE number = '1')
TO (SELECT FROM Object3D WHERE path = 'path1')
SET translation = [0, 0, 0];
Question: Knowing only the product number, how can I fetch properties both from Object3D vertex and corresponding has_Object3D edge in one query?
Something like this (not working):
SELECT
expand(out('has_Object3D')),
outE('has_Object3D').translation
FROM Product
WHERE number = '1';
Thanks.

Answer 1

Try this:
select out('has_Object3D').path as path, outE('has_Object3D').translation as translation from Product where number = "1"
this is the output:
+----+-------+-----------+
|# |path |translation|
+----+-------+-----------+
|0 |[path1]|[[0,0,0]] |
+----+-------+-----------+
UPDATE
select out('has_Object3D').path as path, outE('has_Object3D').translation as translation from Product where number = "1" unwind path, translation
this is the output:
+----+-----+-----------+
|# |path |translation|
+----+-----+-----------+
|0 |path1|[0,0,0] |
+----+-----+-----------+
Hope it helps

However the answer posted by #michela-bonizzi works there might be issues when there is more than one edge between vertices.
The following query is more generic and also works as expected.
MATCH {class: has_Object3D, as: e}.outV() {where: (number = '1')}
RETURN
e.inV().path AS `path`,
e.translation AS `translation`
