      Insert

      Overview

      The insert().into() clause allows for the insertion of new nodes or edges within a single schema in a graphset.

      // Inserts nodes
      insert().into(<schema>).nodes([
        {<property1>: <value1>, <property2>: <value2>, ...},
        {<property1>: <value1>, <property2>: <value2>, ...},
        ...
      ])
      
      // Inserts edges
      insert().into(<schema>).edges([
        {<property1>: <value1>, <property2>: <value2>, ...},
        {<property1>: <value1>, <property2>: <value2>, ...},
        ...
      ])
      
      Method
      Param
      Description
      Optional
      into() <schema> Specifies the node or edge schema (e.g., @user) No
      nodes() / edges() List of property specifications Allows insertion of one or more nodes or edges into the specified schema, with each property specification wrapped in {}. No

      In the property specifications, each provided property will be assigned its given value, while any missing custom properties will default to null.

      Please note:

      • Node _id values are automatically generated by the system if not provided, though custom unique values can be assigned if desired.
      • Node and edge _uuid values are always generated by the system and cannot be manually assigned.
      • Edge properties _from and _to (or _from_uuid and _to_uuid) must be provided to specify the source and destination nodes of the edge.

      Example Graph

      To create the graph, execute each of the following UQL queries sequentially in an empty graphset:

      create().node_schema("user").edge_schema("follow")
      create().node_property(@user, "name").node_property(@user, "age", int32).node_property(@user, "location", point).node_property(@user, "interests", "string[]").edge_property(@follow, "time", datetime)
      insert().into(@user).nodes([{_id:"U001", name:"Jason", age:30}, {_id:"U002", name:"Tim"}, {_id:"U003", name:"Grace", age:25}, {_id:"U004", name:"Ted", age:26}])
      insert().into(@follow).edges([{_from:"U004", _to:"U001", time:"2021-9-10"}, {_from:"U003", _to:"U001", time:"2020-3-12"}, {_from:"U004", _to:"U002", time:"2023-7-30"}])
      

      Inserting a Single Node/Edge

      To insert a node into @user:

      insert().into(@user).nodes({_id: "U005", name: "Alice"})
      

      To insert an edge into @follow:

      insert().into(@follow).edges({_from: "U002", _to: "U001", time: "2023-8-9"})
      

      When inserting a single node or edge, the outer brackets [] in nodes() or edges() can be omitted.

      Inserting Multiple Nodes/Edges

      To insert three nodes into @user:

      insert().into(@user).nodes([
        {_id: "U006", name: "Lee", age: 12},
        {name: "Alex"},
        {}
      ])
      

      To insert two edges into @follow:

      insert().into(@follow).edges([
        {_from: "U001", _to: "U002"},
        {_from: "U004", _to: "U003", time: "2023-9-10"}
      ])
      

      Returning Inserted Data

      To insert two edges into @follow and return all the information of the inserted edges:

      insert().into(@follow).edges([
        {_from: "U001", _to: "U004"},
        {_from: "U001", _to: "U003", time: "2022-2-7"}
      ]) as e
      return e{*}
      

      Result: e

      _uuid
      _from
      _to
      _from_uuid
      _to_uuid
      schema
      values
      Sys-gen U001 U004 UUID of U001 UUID of U004 follow {time: null}
      Sys-gen U001 U003 UUID of U001 UUID of U003 follow {time: "2022-02-07 00:00:00"}

      Providing Point-Type Values

      You need to use the point() function to specify the value of a point-type property.

      To insert a node into @user while providing the value for the property location of the point type:

      insert().into(@user).nodes([
        {location: point({latitude: 132.1, longitude: -1.5})}
      ]) as n
      return n.location
      

      Result:

      n.location
      POINT(132.1 -1.5)

      Providing List-Type Values

      To insert a node into @user while providing the value for the property interests of the string[] type:

      insert().into(@user).nodes([
        {interests: ["violin", "tennis", "movie"]}
      ])
