So I got this to work with a different query using eval().
Is this the right way to do this?
String query = "select key, received as previous, $temp[0].current as
current, $temp[0].delta as delta from Activity, let $temp = (select
received as current, eval('received - $parent.current.receive
I'm trying to calculate the delta value between two rows for one particular
column. OrientDB doesn't support joins as far as I can tell so I'm trying
to accomplish same with sub queries, but I get results i don't understand.
Can someone suggest proper way to accomplish this.
package
Using orient 1.7.7
Thanks

Thanks Lvc. Will Look into it. Is there a similar class available to
convert from ODocument to an object of given type.
I'm using ODocument API. That's why I was looking into this.
Thanks

Hi Alexandre,
"local" is deprecated and will be removed in 2.0. Use plocal instead.

Hi,
We store all the information in more files under the same directory.

I'd like to do so. I searched for a good tools to store information in

Thank you for all this information, Dexter. Very very interesting.
I will look into details at your project too, by individual curiosity :)

Hi Leny,
Our project - NDEx - at UCSD is using OrientDB for its backend data store of
biological networks. (see www.ndexbio.org for background on what we are doing)
We were initially using OrientDB via tinker pop and SQL but we have eliminated
tinker pop to simplify and streamline our access.
HI Dexter,
Thank you for your answer. I have never heard about this JS library. i am
going to take a look to Cytoscape right now.
Did you personaly use Cytoscape?
Do you have any feedback about integrating OrientDB and Cytoscape?
Thank you very much for your help.

Another one to consider is cytoscape.js

Hi Luca!
Wow! it was fast :) .. Thank you very much!
For some time i will use it myself, so my own usage will drive future
improvements.
And, of course, i will respond to all reported issues (maybe feature
requests).

Hi Alexander,
Starting from Blueprints 2.5.x, the OrientDB Graph API, the begin() has
been removed because transactions are always implicit:

Hi all,
I am searching for a solution to visualize dynamically an OrientDB graph in
a web application.
Because I want a dynamic visualization solution, I do want to a solution
that implies to write and load a file (like GEXF files).
I do not need to display huge graphs (so the performance is no
Forget about this. PEBKAC. Works fine, problem with which database was
being connected to.

I have a database I created and populated using the tinkerpop blueprints
API.
id is an Integer
date is a java.Util.Date
Vertex vip = graph.addVertex("class:UserDay", "ID", id, "DATE", date);
When I wish to query the database I am using straight orient SQL becuase I
