Orientdb查询孩子

Question

是否与Orientdb 2.1.11（数据库文件）的方式来获得EmebeddedList

这里是类结构

{ 
    "@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 
     } 
    ] 
} 

我想一个查询，将返回以下内容：

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

我复制了你的结构

和我已经使用这个查询

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) 

希望它可以帮助
