Hi guys,
I am a newbie with OrientDB, my OrientDB is 2.0.8.
At this post:
http://orientdb.com/docs/last/Tutorial-Using-schema-with-graphs.html
After create vertex and edge successful, I can't query the link between
Person and Car which created in previous step.
Here is my detail console, please help me to understand this problem.
Thanks a lot.
Query detail:
orientdb {db=test}> CREATE VERTEX Person SET name = 'Luca'
Created vertex 'Person#12:2{name:Luca} v5' in 0.004000 sec(s).
orientdb {db=test}> CREATE VERTEX Car SET name = 'Ferrari Modena'
Created vertex 'Car#13:2{name:Ferrari Modena} v4' in 0.003000 sec(s).
orientdb {db=test}> CREATE EDGE Owns FROM ( SELECT FROM Person ) TO (
SELECT FROM Car )
Created edge '[Owns#14:5{out:#12:2,in:#13:2} v5]' in 0.009000 sec(s).
*PROBLEM HERE:*
*orientdb {db=test}> SELECT NAME FROM ( SELECT EXPAND( OUT( 'Owns' ) ) FROM
Person WHERE name = 'Luca' )*
