Orientdb查詢孩子

Question

是否與Orientdb 2.1.11（數據庫文件）的方式來獲得EmebeddedList

這裏是類結構

{ 
    "@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 
     } 
    ] 
} 

我想一個查詢，將返回以下內容：

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

我複製了你的結構

和我已經使用這個查詢

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) 

希望它可以幫助
