Polymorphism

Example 1

Find all Locations (Services + Attractions) connected with Customer with OrderedId 1:

MATCH {class: Customers, as: customer, where: (OrderedId=1)}--{Class: Locations, as: location} 
RETURN $pathelements

In the Graph Editor included in Studio, using 'RETURN $pathelements' as RETURN clause, this is the obtained graph:

In the Browse Tab of Studio, using 'RETURN [email protected] as Location_RID, location.Name as Location_Name, location.Type as Location_Type' as RETURN clause, this is the obtained list of records (only few records are shown in the image below):

Example 2

Find the 3 Hotels that have most reviews:

SELECT 
  @rid as Hotel_RID,
  Name as Hotel_Name,
  Type as Hotel_Type,
  out("HasReview").size() AS ReviewNumbers 
FROM `Hotels` 
ORDER BY ReviewNumbers DESC 
LIMIT 3

In the Browse Tab of Studio, using the query above, this is the obtained list of records:

In a similar way:

Find the 3 Restaurants that have most reviews:

SELECT
  @rid as Restaurant_RID,
  Name as Restaurants_Name,
  Type as Restaurants_Type,
  out("HasReview").size() AS ReviewNumbers 
FROM `Restaurants` 
ORDER BY ReviewNumbers DESC 
LIMIT 3

In the Browse Tab of Studio, using the query above, this is the obtained list of records:

In a polymorphic way:

Find the 3 Services (Hotels + Restaurants) that have most reviews:

SELECT 
  @rid as Service_RID,
  Name as Service_Name,
  Type as Service_Type,
  out("HasReview").size() AS ReviewNumbers 
FROM `Services` 
ORDER BY ReviewNumbers DESC 
LIMIT 3

In the Browse Tab of Studio, using the query above, this is the obtained list of records:
