Could you share the script to generate your database?
This seems to me
Is it correct to say that in a RDBMS a query like:
SELECT * FROM tab0,tab1,...,tabN WHERE tab0.idTab1 = tab1.idTab1 AND ...
AND tabN-1.idTabN = tabN.idTabN AND tabN.integerN = 1
correspond to
SELECT * FROM (TRAVERSE * FROM tab0) WHERE integerN = 1
Where each link from class1 to classN is pro

Thank you again, now I'm starting to get the point.
Just another question.
Suppose that I want to extend this reasoning to a deeper level (e.g. 3
classes linked together in this way: 0 -> 1 -> 2), I tried with this query
but I don't get any result
select * from tab0 where 1 in linkTab1.linkTab2.

Thanks!
the problem is that I only get information from the first class (tab0).
orientdb {OrientBench}> select * from tab0 where 12 in linkTab1.integer1
+---+++
# |@RID |linkTab1|integer0|string0
+---+---
linkTab1.integer1 is a collection, try with:
select * from tab0 where 12 in linkTab1.integer1

Hi!
I'm trying to work with relations on OrientDb.
I create 2 classes.
The first has a linkset property to the second.
I populated those two classes with random numbers, then I linked the
documents of the first class (with the same value on "integer*" property)
to the documents of the second.
