I have some data nodes and several evaluation agencies. Each organization groups some or all of these data and sets its own group label. Our needs are: merge the nodes that were originally grouped together into a new group, and reset the new group label. For example: there are 8 nodes of A, B, C, D, E, F, G, H, I, J, and there are 3 evaluation agencies a, b, ca. The data grouping and labeling of the agency are: A, B is 1 group, C, D, E are 2 groups. The organization's data grouping and grouping labels are: A, F for group 1, C, D for group 2, G for group 3. c The data grouping and grouping labels of the organization are: A, B is group 1, C, E is group 2, G, H is group 3, I, J is group 4. Therefore, our final grouping and group labels are: A, B, F for 1 group, C, D, E for 2 groups, G, H for 3 groups, I, J for 4 groups. What should I do with neo4j?Thank you very much!
Hello @ruanlovelin,
Could you provide some samples of the Cypher you've attempted, and a sample graph of what you're describing? This question reads like an an math exam word problem, and that's not a great way to get help.
Put code within tripple ticks
```
MATCH (a:Thing)
```
becomes
MATCH (a:Thing)
Post visuals of your graph
It's much easier to see a graph, than build in in your head from a text description. Either screenshots from the Neo4j Browser (I prefer Greenshot), or with a simple graph tool, like Arrows.
Sorry, I did n’t describe it clearly. Now the problem is solved. My problem is : I only have nodes, but no relationship between the nodes, so I can not carry out the next analysis and query. My solution is t： use the attributes shared by the nodes in each group as relationships.Thank you very much!
The next problem I encountered was: I exported some data from neo4j through Brower's "Export CSV". Some of the data has changed. For example: "0000612" is transformed into "612". what should I do?Thank you very much!
Hello,
If it's an integer, that's normal but if you want to keep the zeros, you can cast as string before to export:
toString(var)

Thank you very much!
