在Couchbase中将计数添加到N1QL查询结果

Question

我有一个N1QL查询：

SELECT p.`ID`, p.`Name` FROM `Preferences` p WHERE `type` = "myType"

结果是对象列表[{"ID": "123", "Name": "John"}, ...]

我想获取结果JSON，例如：

{
  "count": 5, 
  "result": [{"ID": "123", "Name": "John"}, ...]
}

如何使用N1QL做到这一点？

Answer 1

SELECT
   COUNT(t.ID) AS count,
   ARRAY_AGG(t) AS results
FROM
    (
      SELECT
        p.`ID`, p.`Name`
      FROM
       `Preferences` p 
      WHERE `type` = "myType"
    ) AS t
