I wanna delete record using JS API. In wiki I found example and I know that exist delete() function but I don't know what paramets needed and can't find documentation about ORid realize interface.
Update
When I create or insert function I get error
Internal server error:
java.lang.IllegalArgumentException: Script pool for database 'myDataBase' is not configured
I use this code:
db.save()
//or
db.executeCommand()
Need help. Maybe who know. Thanks
You can use this code for a graph database
var g=orient.getGraph();
var vertex=g.getVertex("your rid");
vertex.getRecord().delete();
and this for a document database
var db=orient.getDatabase();
var document=db.query("select from #21:0");
document[0].delete();
Hope it helps

I'm trying to use TransactionEventListener in neo4j. There don't seem to be any lifecycle hooks for plugins, so I figure the only way to do it is to have a plugin procedure do it. However, trying to do that gives me this error:
Neo4jError: Writing in read access mode not allowed. Attempted write to internal graph 1 (system)
The plugin uses write mode, even if I'm not actually writing anything to the database; I'm just registering that TransactionEventListener, although that could indeed lead to writes later on. Still, I've got Write mode.
Here's my procedure:
#Procedure(name = "setTransactionListener", mode = Mode.WRITE)
public Stream<BuiltInProcedures.NodeResult> setTaxonomy(
#Name("taxonomy") Map<String, Map<String, Object>[]> taxonomy
) {
var managementService = new DatabaseManagementServiceBuilder(Path.of(".")).build();
var listener = new ValidationTransactionListener(taxonomy);
managementService.registerTransactionEventListener(db.databaseName(), listener);
return null;
}
Best guess is that I'm not supposed to register a transaction listener this way. But if not this way, then how? There don't seem to be any lifecycle hooks that get called when the database starts, so how can I possibly register an transactionEventListener?
Or is there a way I can give myself permission to do this?
What do you actually want to do?
It doesn't work like that, you need to register the listener in the database lifecycle within a KernelExtensionFactory?
See here for an example:

I'm using the following flutter code to query firestore which orders the data using the field timestamp.
var results = Firestore.instance.collection('post').orderBy('timestamp').getDocuments().then((value) {
var list = value.documents;
return list.map((doc) {
return doc.documentID;
}).toList();
});
When I run this code, it throws the below exception saying an index is required:
W/Firestore(31110): (21.3.0) [Firestore]: Listen for Query(app/jQH7Fp9xCZWYiqZRe7lE/post where readAccess array_contains_any [WzKImODx6WYVqdSW3D9Az3xrUnM2, PUBLIC] order by -timestamp, -name) failed: Status{code=FAILED_PRECONDITION, description=The query requires an index. You can create it here: https://console.firebase.google.com/v1/r/project/....
The exception even comes with a nice link. When opening that link, a nice UI pops up giving me the ability to create the index, with just a simple click:
Question: simple as the above may seem, I'm not very happy with this. I prefer to be able to create the index from fluttercode. In code I'm looking for something like the below:
Firestore.instance.collection('post').API-TO-CREATE-INDEX('timestamp');
Does it exist? Please advise. Many thanks.
It's not possible to create an index from client apps. You have three main choices:
Clicking the link you already saw.
Using the Firebase CLI to deploy the index from the command line.
Using the gcloud CLI to also deploy from the command line
See also the documentation on managing indexes.
I'm having some troubles understanding, what i believe is trivial but i can't seem to get my head around it.
I have this publish function in server.js (server only)
Meteor.publish("tikiMainFind", function(){
return tikiDB.find()
})
In app.js (server + client) i'm declaring this mongo collection:
tikiDB = new Mongo.Collection("tiki")
Why is it that this doesn't work in client.js
console.log(tikiDB.find())
//ReferenceError: tikiDB is not defined
Without any idea how you have your app structured, I agree with David Weldon's answer. Check File Load Order to see what order your files are getting loaded.
I am learning PhoneGap for an app project and need to use the database for certain aspects, I am trying out the Nova Data framework,
https://cordova.codeplex.com/wikipage?title=How%20to%20use%20nova.data
I am trying to use my code to put together a test entity, but I am getting a db error telling me there is a missing table. The documentation does not specify that the database should be created beforehand, but I am starting to think that may be the case. Has anyone out there used the Nova framework in a project? I just need a little guidance.
Here is my code I am using to kick off the DB Context:
var DataContext = function () {
nova.data.DbContext.call(this, "HealthDb", "1.0", "Health DB", 1000000);
this.Temperatures = new nova.data.Repository(this, Temperature, "Temperatures");
};
DataContext.prototype = new nova.data.DbContext();
DataContext.constructor = DataContext;
And my entity (Temperature) :
var Temperature = function () {
nova.data.Entity.call(this);
this.Value = 101;
};
Temperature.prototype = new nova.data.Entity();
Temperature.constructor = Temperature;
It is creating an empty database with the proper name, just no tables! I am grateful for any assistance!
Thanks for using our library. I have made the html5 sqlite as a standalone library. Please get it from github.
A live demo link is also available there. And the documentation is more complete. The lib itself has also been updated and a few bugs fixed.
Thanks,

Turns out I was trying to start up the dbcontext before I defined my entity classes....
Changed the order of my js files and it works.
I am newcomer to Javascript and have been tasked with migrating our product's UI from YUI2 to YUI3.
It doesn't look like there's a migration guide anywhere, so I'm browsing internet posts and the yui docs for now.
In my global scope, I've temporarily added something like var Y = YUI().use('*',function(Y){});
I've encountered a YAHOO.util.Dom.get(...) elsewhere which doesn't work with YUI3, and it looks like Y.DOM.byId(...) is the recommended migration. But, I'm getting the error that "Y.DOM" is undefined!
Whoever's using Y.DOM.(...), how did this get resolved?
I don't know where you found the idea of Y.DOM.byId
Try
var node = Y.one('#elementID');
or if you want to use classes:
var nodes = Y.all('.className');
For more information on how to get nodes in YUI3, see their documentation
EDIT:
<script>
YUI().use('node', function (Y) {
var node = Y.one('#elementID');
});
</script>
