如何找到用户的联合朋友

Question

我有一个有朋友的用户：

User {
    "@rid:": "#11:2"
    ...
    friends: ["#61:1", "#61:2", "#61:3"]
}
...


User {
    "@rid:": "#11:3"
    ...
    friends: ["#61:2", "#61:3","#61:4"]
}

如何使用osql找到用户的共同朋友（＆＃34;＃11：2＆＃34;，＆＃34;＃11：3＆＃34;）？

因此查询应返回"#61:2", "#61:3"。

Answer 1

试试这个：

select from User where @rid in (select out() from User where @rid = "#11:2") and @rid in (select out() from User where @rid = "#11:3")

希望有所帮助
