Hi, all. I am trying to calculate the duration between two connected nodes and place it on the relationship This duration is calculated in seconds and is converted to an integer. E.g.. node: IDeventtime12020/2/10 10:00:0022020/2/10 10:00:1232020/2/...

Hi, Relationship is already there between the node. Is there any way to convert the format on Neo4j? From '2020/02/10 10:00:00' to '2020-02-10T10:00:00Z' Thanks for your reply.

Thank for your reply. It work! What if I want to give relationships based on the same WAFERID and FROMTIME order of their occurrence? E.g.. node: WAFERIDfromtimetotimeWORKSTEPA110:0010:01process A1A110:0110:03process A2A110:0310:05process A3 I want ...

Thank for your reply. I found the cypher to query my question. MATCH(g:Task)-[r:chamber_path]->(b:Task{FROMLOCTYPE:g.FROMLOCTYPE}) WITH g.PPID AS PPID, collect(r.time) AS duration,g.FROMLOCTYPE as FROMLOCTYPE UNWIND duration AS val WITH max(val) as ...
