英文:
Couchbase N1QL query with dictionary
问题
在Couchbase中，我有包含以下结构的文档：
{
"...": "...",
"members": {
"*USERID*": {
"...": "..."
}
}
}
现在我想使用N1QL查询来获取所有包含我的用户ID作为members中键的文档。我尝试了许多不同的查询，但未能找到一个有效的N1QL查询。
一个选择所有包含指定用户ID作为members映射键的文档的N1QL查询是什么样的？
英文:
In Couchbase I have documents that contain a dictionary structured like this:
{
"...": "...",
"members": {
"*USERID*": {
"...": "..."
}
}
}
Now I want to use a N1QL Query to get all documents where my user id is in members. I have tried many different queries, but I was not able to find a working N1QL query.
What does a N1QL Query look like that selects all documents with a specified user id as a key in the members map?

SELECT d.*
FROM default AS d
WHERE d.members.["myuserid"] IS NOT NULL;
OR
SELECT d.*
FROM default AS d
WHERE ANY n IN OBJECT_NAMES(d.members) SATISFIES n = "myuserid" END;
OR
SELECT d.*
FROM default AS d
WHERE ANY n:v IN d.members SATISFIES n = "myuserid" END;
英文:
SELECT d.*
FROM default AS d
WHERE d.`members`.["myuserid"] IS NOT NULL;
OR
SELECT d.*
FROM default AS d
WHERE ANY n IN OBJECT_NAMES(d.`members`) SATISFIES n = "myuserid" END;
OR
SELECT d.*
FROM default AS d
WHERE ANY n:v IN d.`members` SATISFIES n = "myuserid" END;
