            How to interpret orientjs query result?
            Asked 2019-Dec-13 at 14:52

            I'm creating an interactive graph in my web page by querying my OrientDB instance using Orientjs then pulling out the needed data from the query and passing it to cytoscape.js. I'm able to get data down from the OrientDB instance and graph it, but I realized that the result of running a query in OrientDB Studio is different than when I run the query through Orientjs. In Studio I get 20 nodes with 67 edges from the query. When I run the same query through Orientjs I get 65 individual objects back. Originally I thought each object represented a node and the 'in_links'/'out_links' were the edges. However, this obviously isn't the case.

            So I figure it is 1 of 3 problems:

            1. Orientjs just isn't working and is giving me back bad data (I think and hope this is unlikely).
            2. I am somehow running the query on two different instances of OrientDB (I'm pretty sure this is impossible).
            3. I am not interpreting the query results from Orientjs correctly and therefore not feeding them into cytoscape.js correctly (I think this is most likely the problem).

            Here are a few examples of the objects I'm getting back from my query:



            Answered 2019-Dec-13 at 14:52

            After some help from the people at Orientjs's GitHub (see here) I've got the answer.

            When running a query on OrientDB studio there is an implicit LIMIT 20 added to each query unless there is a limit specified. I went back and specified a limit of 100 and sure enough I had the same number of nodes being rendered as there were objects from the Orientjs query. From there is confirmed the number of edges. So the above description of what the result of a Orientjs query means is correct: each object is a node and the in/out_links are the edges. The key to the edges is that if there is the same ID in the in_link of one vertex and the out_link of another vertex, those two vertices are connected by that edge.

            Error while executing gremlin query on OrientDB
            Asked 2019-Feb-19 at 21:39

            The following query when run from OrientDB studio gives error.

            Query: g.V('userId', 'SDWEQS').repeat(out()).until(has('organizationId','org1'));


            groovy.lang.MissingMethodException: No signature of method: com.tinkerpop.gremlin.groovy.jsr223.GremlinGroovyScriptEngine.out() is applicable for argument types: () values: [] Possible solutions: put(java.lang.String, java.lang.Object), get(java.lang.String), wait(), any(), dump(), wait(long)

            I tried running the query using the OrientJs Node app but get the same error. I created the same graph on gremlin server and this query works there.

            My question is whether orientdb supports repeat()? Please suggest alternatives to make the above query work.



            Answered 2017-Jul-11 at 12:10

            What I found is that OrientDB is only supporting gremlin queries of Tinkerpop 2.x. And "repeat()" wasn't part of 2.x. I will have to rework the query to use "loop()" instead.

            Building GraphQL Resolver to Return List of Strings -- Receiving [object Object] Instead of Strings
            Asked 2018-Oct-27 at 01:16

            I am developing a web application that queries an OrientDB Graph Database using GraphQL. It uses Apollo Server to resolve incoming GraphQL queries.

            I want to build a query that will simply return the 'name' field for each "Topic" Object as a list of Strings. e.g.:



            Answered 2018-Oct-27 at 01:16

            Your initial approach didn't work as expected because you were returning an array of objects. Your second attempt returns null because you don't return anything inside your resolver. Your resolver should always return a value or a Promise that will resolve to that value, otherwise the resolved value for the field will always be null.

            The value of the_list_of_records will be a Promise, so you can just return that and that should be sufficient. But we can make this code a little easier to read using map like this:

            Connecting to OrientDB in NodeJS using OrientJS module -- "Socket Closed" Error
            Asked 2018-Aug-21 at 16:32

            I'm developing an application in NodeJS (v8.11.3) using OrientJS (v2.2.10) that will connect to a locally-hosted OrientDB (v3.0.6) database and query it. However, when I attempt to run my program, I receive a "Socket Closed" error every time.

            I am able to connect to the database and query it through both OrientDB's console and through the web-interface, so I know the database is accessible at the address http://localhost:2480. If I run "netstat -a" in the Command Prompt, I can see that port 2480 is Listening for a TCP connection.

            This is the code I am currently running:



            Answered 2018-Aug-21 at 16:32

            After further investigation, I've found the source of the problem.

            As it turns out, OrientDB hosts its service on two ports: 2480 (HTTP) and 2424 (Binary). Connecting to OrientDB via the OrientJS module requires using port 2424 rather than 2480. This solved my problem.

            Create a model for OrientDB database in node.js
            Asked 2018-Apr-16 at 21:06

            Iam building a node js application and OrientDB as the database. Is there someway to create a model for my vertices in node like we do if were using MongoDB?

            For instance, I have a class called Account with propertise name, password and email.

            Is it possible to create a model for this in node when using OrientDB and OrientJS as the language driver?

            Appreciate any help.

            Unsubscribe live query in OrientJS
            Asked 2018-Apr-16 at 09:25

            I use OrientJS with OrientDB to perform livequery. The subscription to live query has no problem but I could not find any way to unsubscribe from that event.



            Answered 2018-Apr-16 at 09:25

            This will unsubscribe from the token which is returned on initializing the live query.

            live unsubscribe ${token}

            This token is acquired by using the returned data from the liveQuery resolver.

            I found the error. It simply was that the parameter nodeFrom was undefined. So passing undefined to db.create('EDGE','RelatedTo).from(undefined).to(nodeTo) produce that error!
