Neo4j loop for all children












1














In Neo4j I got the following nodes:
enter image description here



As you can see, they are siblings connected by relationships as NEXT or NEXT_SIBLING; moreover, the first and last child are connected to the father by FIRST_CHILD_OF and LAST_CHILD_OF.



I simply want to find a way to cycle them in order to create a single string which is "A B C D".



Is there a Cypher query capable of this?

          Creating your model



          For the ease of possible further answers and solutions I note my graph creating statement:



          CREATE
          (ormText:OrmText {name: 'orm_Text'})<-[:FIRST_CHILD_OF]-(letterA:Letter {name: 'A'}),
          (letterA)-[:NEXT]->(letterB:Letter {name: 'B'}),
          (letterA)-[:NEXT_SIBLING]->(letterB),
          (letterB)-[:NEXT]->(letterC:Letter {name: 'C'}),
          (letterB)-[:NEXT_SIBLING]->(letterC),
          (letterC)-[:NEXT]->(letterD:Letter {name: 'D'}),
          (letterC)-[:NEXT_SIBLING]->(letterD),
          (letterD)-[:LAST_CHILD_OF]->(ormText);


          graph



          Solution



          MATCH
          letterPath = (startLetter)-[:NEXT|NEXT_SIBLING*]->(endLetter)
          WHERE
          (startLetter)-[:FIRST_CHILD_OF]->(:OrmText)<-[:LAST_CHILD_OF]-(endLetter)
          WITH nodes(letterPath) AS letterNodes
          UNWIND letterNodes AS letterNode
          RETURN DISTINCT letterNode.name AS letterName;


          The second line detects the startLetter as first child of orm_Text and the endLetter as last child of orm_Text.
          In line five the path between the start and end letter is calculated, its nodes were extracted in line six. Line seven creates singles nodes and line eight finally returns the result.



          Note: By writing -[:NEXT|NEX_SIBLING*]-> a relationship of type NEXT or NEXT_SIBLING is valid for a match. If your requirement only need one specific type, remove the other and the |.

            To return properties of the OrmText label, you must specify the node variable first and loop it through each WITH clause. Solution: MATCH letterPath = (ormText:OrmText)<-[FIRST_CHILD_OF]-(startLetter:Letter)-[:NEXT|NEXT_SIBLING*]->(endLetter:Letter)-[LAST_CHILD_OF]->(ormText) WITH nodes(letterPath) AS letterNodes, ormText.name AS ormTextName WITH filter(x IN letterNodes WHERE NOT (x:OrmText)) AS letterNodes, ormTextName RETURN DISTINCT reduce(s = head(letterNodes).name, n IN tail(letterNodes) | s + ' -> ' + n.name) AS letterString, ormTextName;.

          Extension



          If you prefer your output in a single String instead of a list of node names have a look at the following solution.



          Solution



          MATCH
          letterPath = (startLetter)-[:NEXT|NEXT_SIBLING*]->(endLetter)
          WHERE
          (startLetter)-[:FIRST_CHILD_OF]->(:OrmText)<-[:LAST_CHILD_OF]-(endLetter)
          WITH nodes(letterPath) AS letterNodes
          RETURN DISTINCT reduce(s=head(letterNodes).name, n in tail(letterNodes) | s+" -> "+n.name) AS letterString;


          Result



          ╒══════════════════╕
          │"letterString" │
          ╞══════════════════╡
          │"A -> B -> C -> D"│
          └──────────────────┘

          Creating your model



          For the ease of possible further answers and solutions I note my graph creating statement:



          CREATE
          (ormText:OrmText {name: 'orm_Text'})<-[:FIRST_CHILD_OF]-(letterA:Letter {name: 'A'}),
          (letterA)-[:NEXT]->(letterB:Letter {name: 'B'}),
          (letterA)-[:NEXT_SIBLING]->(letterB),
          (letterB)-[:NEXT]->(letterC:Letter {name: 'C'}),
          (letterB)-[:NEXT_SIBLING]->(letterC),
          (letterC)-[:NEXT]->(letterD:Letter {name: 'D'}),
          (letterC)-[:NEXT_SIBLING]->(letterD),
          (letterD)-[:LAST_CHILD_OF]->(ormText);


          graph



          Solution



          MATCH
          letterPath = (startLetter)-[:NEXT|NEXT_SIBLING*]->(endLetter)
          WHERE
          (startLetter)-[:FIRST_CHILD_OF]->(:OrmText)<-[:LAST_CHILD_OF]-(endLetter)
          WITH nodes(letterPath) AS letterNodes
          UNWIND letterNodes AS letterNode
          RETURN DISTINCT letterNode.name AS letterName;


          The second line detects the startLetter as first child of orm_Text and the endLetter as last child of orm_Text.
          In line five the path between the start and end letter is calculated, its nodes were extracted in line six. Line seven creates singles nodes and line eight finally returns the result.



          Note: By writing -[:NEXT|NEX_SIBLING*]-> a relationship of type NEXT or NEXT_SIBLING is valid for a match. If your requirement only need one specific type, remove the other and the |.



          Result



          ╒════════════╕
          │"letterName"│
          ╞════════════╡
          │"A" │
          ├────────────┤
          │"B" │
          ├────────────┤
          │"C" │
          ├────────────┤
          │"D" │
          └────────────┘

          • Thanks, I understand the approach and I'm sure it's correct, but I got the error "Variable ormText not defined ". Even creating a new MATCH at the beginning with this var, returns 0 records. Am I missing something?

            @Wall Sorry, it was my fault. During the optimization something slightly screwed up. I corrected both MATCH statements, now the rendered result should be displayed again.

            To return properties of the OrmText label, you must specify the node variable first and loop it through each WITH clause. Solution: MATCH letterPath = (ormText:OrmText)<-[FIRST_CHILD_OF]-(startLetter:Letter)-[:NEXT|NEXT_SIBLING*]->(endLetter:Letter)-[LAST_CHILD_OF]->(ormText) WITH nodes(letterPath) AS letterNodes, ormText.name AS ormTextName WITH filter(x IN letterNodes WHERE NOT (x:OrmText)) AS letterNodes, ormTextName RETURN DISTINCT reduce(s = head(letterNodes).name, n IN tail(letterNodes) | s + ' -> ' + n.name) AS letterString, ormTextName;.
