      SKIP

      Vue d’ensemble

      L'instruction SKIP vous permet de supprimer un nombre spécifié d'enregistrements depuis le début de la table de travail actuelle. Un entier non négatif doit être spécifié dans la clause SKIP.

      OFFSET peut être utilisé comme synonyme de SKIP.

      <skip statement> ::= "SKIP" <non-negative integer>
      

      Exemple de Graph

      Les exemples suivants s'exécutent sur ce graph :

      Pour créer ce graph, exécutez la requête suivante sur un graph vide :

      INSERT (p1:Paper {_id:'P1', title:'Efficient Graph Search', score:6, author:'Alex'}),
             (p2:Paper {_id:'P2', title:'Optimizing Queries', score:9, author:'Alex'}),
             (p3:Paper {_id:'P3', title:'Path Patterns', score:7, author:'Zack'}),
             (p1)-[:Cites {weight:2}]->(p2),
             (p2)-[:Cites {weight:1}]->(p3)
      

      Ignorer N Enregistrements

      MATCH (n:Paper)
      RETURN n.title SKIP 1
      

      Résultat :

      n.title
      Efficient Graph Search
      Path Patterns

      Ignorer N Enregistrements Ordonnés

      MATCH (n:Paper)
      ORDER BY n.score 
      SKIP 1
      MATCH p = (n)->()
      RETURN p
      

      Résultat :

      p
      (:Paper {_id: "P2", score: 9, title: "Optimizing Queries", author: "Alex"})-[:Cites {weight: 1}]->(:Paper {_id: "P3", score: 7, title: "Path Patterns", author: "Zack"})
