Adding Nodes and Edges

​

Creation Operations

These operations allow you to add new elements to your graph.

​

AddN

Create new nodes in your graph.

AddN<Type>
AddN<Type>({properties})

• Example: Adding Nodes

  QUERY CreateUsers () =>
      // Create an empty user node
      basic_user <- AddN<User>
      // You could also write it like this
      AddN<User>
  
      // Add a user with properties
      detailed_user <- AddN<User>({
          name: "Alice Johnson",
          age: 30,
          email: "alice@example.com"
      })
  
      RETURN basic_user, detailed_user

AddE

Create connections between nodes in your graph.

AddE<Type>::From(v1)::To(v2)
AddE<Type>({properties})::From(v1)::To(v2)

• Example: Adding Edges

  QUERY CreateRelationships(user1ID: String, user2ID: String) =>
      // Get the users by their IDs
      user1 <- N<User>(user1ID)
      user2 <- N<User>(user2ID)
  
      // Create a simple follows relationship
      follows <- AddE<Follows>::From(user1)::To(user2)
  
      // Create a detailed friendship with properties
      friendship <- AddE<Friends>({
          since: "2024-01-15",
          strength: 0.85,
          tags: ["college", "roommates"]
      })::From(user1)::To(user2)
  
      RETURN follows, friendship

  Example: Adding Edges in a Traversal

  You can also use the AddE operation in the middle of a traversal to add edges between a list of nodes or vectors.

  QUERY CreateFriendships(user1ID: String, user2ID: String) =>
  // This makes every user in the database follow the user with ID user1ID
  user1 <- N<User>::AddE<Follows>::To(N(user1ID))
  
  // This makes user with userID2 follow every user in the database
  user1 <- N<User>::AddE<Follows>::From(N(user1ID))
  
  RETURN friendship
