Hello everyone.
missing some images
where can i find them?


I am newbie to OrientDB, and trying out Graph Model. I am running into few problems with UPSERT code using Java drivers. I am not able to find a way to use MERGE <JSON> using .command API. I also tried looking for POJO way of upsetting, but couldn’t find the driver documentation. I would greatly appreciate if anyone can point me documentation or some examples.

whats the story with OrientDB? It seemed active last year.
Did the community channel move somewhere else?

When I try to import a public database I get An error occurred when trying to reach public databases repository. Please check your connection.I noticed this issue that is closed: orientechnologies/orientdb-studio#391 and I also tried the url listed there: http://www.orientechnologies.com/public-databases/config.json and it gets a http 502 and times out. Is there another way to load sample databases?
hmm.. juniper. alrighty then.. Good luck and goodnight :D

Hey there. I would love to know the state of .NET (Core) support for OrientDB. All available drivers haven't been updated in ages, are incompatible with 3.x and frankly in a sorry state. Github issues go unanswered for years, etc, etc.
Any word on this would be much appreciated.
Hey ! I was wondering if a 2.2.38 release is planned ? thank you!

I have a problem with function using. I need help.
I have a JS function with body: return orient.getDatabase().query("select expand(outE(?).inV()) from " + fromRID)
The function returns collection of @rid only.
How I can take all result documents ?
Hey guys, i’ve got a db running on a server and i want to grab a copy of that DB and put it on another machine. I’m currently using the export command to export the data and the import command to import the data but when i import, the @Rid of the entities change which screws up my data. Is there any way to preserve the @RID of the data?

Aloa people. Anyone knows how I can filter a collection property to include any element of a collection parameter?
e.g. if the property is [1,2,3,4,5], I want to check if there is any element that is inside [3,9] (hence true)
Hi guys, I am new to orientdb and I just installed the latest stable release (3.0.21), but the graph APIs seem to be very different from the ones in the official documentation (e.g. g.V() does not work, g.vertices() works), any ideas why?

HI All, has anyone encountered WINCH signal issue on OrientDB?
Also, i was wondering if i am using plocal method, whats the way to create a database if it doesnt exist and login back once created

When I run
match {class: Employee, as: emp, where: (Name = 'James')}.out('hasEmpID') {class: EmployeeID,as: eid, where: (id='0110')} return eid
using the java Graph API instead of returning the vertex it returns null (to be specific It returns #-1:-2{pp:#69:12} v0). The vertex I require is present in the data structure but I am unable to access it.

The snippet of code i used is from the doc
for(Vertex employeeIdVertex : (Iterable<Vertex>) graph.command(new OCommandSQL(query)).execute()){
// Do the relevant op with the vertex

Could you please guide me through as to how to fetch the eid node from the query? (If I use $elements I get all the nodes in the path, but that would require additional traversing code which I find cubersome)

Hello, Any steps towards running OrientDB with Haskell, besides the effort at: https://github.com/GoorMoon/orientdb
I would like to migrate my database from RDBMS to orientdb community version and I would like to host it on my website with the expectation that the users on my website will be able to look at the exact information at the same time. Will that be possible? If yes, then how many users can view the same part of the graph at the same time ?
Please let me know as soon as possible.
Can someone please help me with your valuable feedback about https://jio.nexedi.com/ ???? Planning to build a full text static search engine for the given files....

Hey all.. I have having trouble clustering... I have 3 servers, hazelcast on tcp, manual hostnames, and netstat on every host says its connected to every other host... but... when I create a database, it is not replicated. In the logs, it only adds a single node to the database: [a3521ae8bb3f] Adding node 'a3521ae8bb3f' in partition: [*] db=my-database v=3 [ODistributedDatabaseImpl$6] ... Any ideas?
