![]() ![]() You can create the nodes and their relationship in one query, too: CREATE (p1:Name. ![]() If you're trying to create many nodes, you would rerun this query for each pair of nodes you want to create, changing the ID you assign each time. The reason your query doesn't work, though, is that by writing MATCH (P:names),(P:names) WHERE P.id = "1" AND P.id = "2", you are essentially saying "find a node, call it 'P', with an ID of both 1 and 2." That's not what you want and it obviously won't work! The problem is in simulating two independent different robots in Gazebo: Copter and Rover with same mavros functionality. Will work, looks so much better(!): MATCH (p1:Name),(p2:Name)ĬREATE (p1)->(p2) RETURN r ![]() Relationships are all caps,, not, though this one gets broken all the time -)īack to your query, it both won't work and it doesn't follow conventions.ĬREATE (P)->(P) RETURN r.Labels are singular and have their first character capitalized: (p1:Name), not (p1:Names) or (p1:names) or (p1:name).It is not an error to create a new variable using the same name. Identifiers start lowercase: person instead of Person1, p instead of P Loop variables (like i ) are a little different, they are only visible in the loop block.Neo4j has some naming conventions that you are not following and as a result, it makes your query harder to read and will be harder for you to get help in the future. Only in case one node is grounded we speak about a 'node voltage' - without mentioning that this automatically means: Referenced to the grounded node. A voltage always is the potential DIFFERENCE between two nodes. The character before the colon when describing a node or relationship is referred to as an identifier, it's just a variable representing a node/rel within a Cypher query. I see that at node A, the voltage is 10V. #NODEBOX SAME NAME DIFFRENT NODE HOW TO#Has the right answer about how to fix your query but I might be able to fill in some details about why and it's too long to leave in a comment. ![]()
