OrientDB查询子

Question

Is there a way with Orientdb 2.1.11 (document database) to get the EmebeddedList

Here is the class structure

{
    "@class":"Quote",
    "number":"Q1",
    "details":[{
      "code":"123",
      "price":10
      },{
      "code":"456",
      "price":20
      }
    ]
},{
    "@class":"Quote",
    "number":"Q2",
    "details":[{
      "code":"789",
      "price":15
      },{
      "code":"951",
      "price":25
      }
    ]
}

I would like a query that will return the following :

number| code | price
------|------|------
Q1    | 123  | 10
Q1    | 456  | 20
Q2    | 789  | 15
Q2    | 951  | 25

Answer 1

I have replicated your structure

and I have used this query

select number, details.code as code, details.price as price from (select prop.number as number, prop.details as details from (select prop from test unwind prop) unwind details)

Hope it helps
