Note that as I go through the exercises, I am testing out "what if" scenarios. This exercise has two parts, asking for ('real OR world') and then also ('real AND world'). Alternatives: Using ('real or world') works. Using ('real' OR 'world') does not...
Hello guys, how are you today? So, I was willing to take an online training and failed due to the sign in button is not working for me. I've tried in Chrome, Edge Chromium and Opera, same results. Did anyone face this issue as well? I click over and ...
Hi All, I'm finding it confusing to navigate the training course. It appears that there are 8 parts to the video in the Evolution of Graph Databases section--how many am I expected to watch before reading on to What is a Graph Database?
Question 3 of the section on Defining Constraints for your data asks "How many properties can be defined for a NODE KEY constraint?" Per section 4.4 of the Cypher Manual, it seems to be unlimited: However, when I choose "unlimited" for the answer, i...
Hello Is it possible to download the training sets used in the graph academy? SO I can load them into my local neo install. Thanks
Some of the queries listed on online training does not work for the older version of the neo4j. Example: https://stackoverflow.com/questions/62365265/neo-clienterror-statement-syntaxerror-invalid-input-l-expected-r-r-or-o-o/62367486#62367486. How as ...
Intro to Neo4j v 4.0, Section on creating nodes. The upper section of the screen print shows what the exercise says should be returned. Below that is what is returned when I execute the query which, you can see, has a lot more info than is displayed ...
A couple questions for general understanding, noting that I am writing queries before moving to the exercise answers... 7.4 - The given solution actually returns nodes and you have to switch to table view to get the list of data. I'm not really clear...
In the section Examining the Data Model, there is an example of "CALL db.schema" but this returns an error. I nosed around after typing "CALL db." and found that "CALL db.schema.visualization" is the appropriate syntax.
Hi - I'm stuck with question 2 in part 3 of the Data Science training. https://neo4j.com/graphacademy/online-training/data-science/part-3/ After trying to work out the answer in the normal way I gave up and resorted to a brute force approach. I have...
How? Clicking the "Open" button doesn't appear to do anything if an existing Neo4j Browser window is already open.
I've now gone through exercise 8 up to 8.12 twice. The first time I would read an exercise then type out how I thought the answer should be formed, go to the next page (where the solution displays) and check to ensure what I wrote matched before play...
I have a question about exercise 5.11: ‘Retrieve the actors who have acted in exactly five movies, returning the name of the actor, and the list of movies for that actor.’ The solution in the course is as follows: MATCH (a:Person)-[:ACTED_IN]->(m:Mov...
This works: MATCH (m:Movie) WHERE m.tagline CONTAINS 'love' RETURN m.title This does not work: MATCH (m:Movie) WHERE toLower(m.tagline) CONTAINS 'love' RETURN m.title The error is "Expected a string value for 'toLower', but got: NO_VALUE..." Same err...
Exercise 6.3 reads as follows: “The results returned from the previous query returns the collection of movie titles with duplicates. That is because there are multiple actors per released year. Next, modify the query so that there is no duplication o...
