So I have data coming in from two different timezones. Both ISO 8601: One looks like this: "2021-02-18T01:00:00+00:00" The other like this: "2021-02-18T00:00:00+01:00" They are essentially the same. There is a Node N with a dateTime property cal...

I am playing around with the new async driver. I am reading in a multitude of paths(together with their parent path) from a directory structure. And want to represent it in neo4j using nodes (:Directory {uncPath:$path}). And they should all be connec...

Hey, what's the best way to find the last leaf node? It's for a timeline like structure where a node is added at the end. Schema looks like this: (:Node)<-[:IS_PARENT]-(:Node)<-[:IS_PARENT]-(:Node)....... So a Node will always only have one parent. I...

We are using Neo4j.Driver and the code looks like this: using (var session = driver.Session(AccessMode.Write)) { var result = [...].WriteTransaction(tx => tx.Run[...] var value1 = result.First()["value1"].As<string>(); var value2 = result.First()["va...

Is there a way to show the datatypes in the neo4j browser? If a property has a number, you can't see if it is a string or a number. Same with boolean, it just shows "PropertyName: true", and you have no idea if it is a boolean true or a string "true"...

Sorry for the late reply: cursor = await session.RunAsync( @"merge (current:Directory {uncPath:$Path}) merge (parent:Directory {uncPath...

Hey, thanks for the answer. I did not consider that it's possible to have a node with the same property but different types. Is that a typical use case? I don't think there are downstream effects. Only it's inconvenient not being sure as to what a "r...

It's like an edge case. Because the node basically has two unqiue properties: id or(exclusive) path. So there can't be nodes that have a duplicate path or id. That's why I can't use 'merge'. If there is a node that already has the id, please match i...
