    Property Management

    Get Property

    Get one property info

    // Get info of node property @user.name 
    prop, _ := client.GetProperty("user", "name", ultipa.DBType_DBNODE, nil)
    log.Println(prop)
    

    Create Property

    Create property for target Schema

    // Create node property
    newNodeProp := &structs.Property{
        Name: "name",
        Type: ultipa.PropertyType_STRING,
    }
    
    resp, _ := client.CreateProperty("target_schema", ultipa.DBType_DBNODE, newNodeProp, nil)
    log.Println(resp.Status.Code)
    
    
    // Create edge property
    newEdgeProp := &structs.Property{
    	Name: "type",
    	Type: ultipa.PropertyType_STRING,
    }
    
    resp2, _ := client.CreateProperty("target_schema", ultipa.DBType_DBEDGE, newEdgeProp, nil)
    log.Println(resp2.Status.Code)
    

    Create Property If Not Exist

    Same function as 'Create Property', return true if the property already exists, return false and create property if the property does not exist yet

    isExist, _ := client.CreatePropertyIfNotExist("target_schema", ultipa.DBType_DBEDGE, newEdgeProp, nil)
    log.Println(isExist)
    

    Alter Property

    // Edit node property @user.name as @user.username and overwrite its description
    propNode := &structs.Property{
      Name: "username",
      Desc: "change property name from name to username",
    }
    resp, _ := client.AlterNodeProperty("@user.name", propNode, nil)
    log.Println(resp)
    
    // Edit edge property @relation.category as @relation.type and overwrite its description
    propEdge := &structs.Property{
        Name: "type",
        Desc: "change property name from category to type",
    }
    resp2, _ := client.AlterEdgeProperty("@relation.category", propEdge, nil)
    log.Println(resp2)
    

    Drop Property

    // Delete node property @user.name
    resp, _ := client.DropNodeProperty("@user.name", nil)
    log.Println(resp)
    
    // Delete edge property @relation.category
    resp2, _ := client.DropEdgeProperty("@relation.category", nil)
    log.Println(resp2)
