想要在使用N1QLCouchbase

Question

当我在查询下面运行时

SELECT * FROM myBucket WHERE ANY x IN transactions SATISFIES x.type in [0,4] END;

结果：

{
  "_type": "Company",
  "created": "2015-12-01T18:30:00.000Z",
  "transactions": [
    {
      "amount": "96.5",
      "date": "2016-01-03T18:30:00.000Z",
      "type": 0
    },
    {
      "amount": "483.7",
      "date": "2016-01-10T18:30:00.000Z",
      "type": 0
    }
  ]
}

我得到多个这样的json

SELECT sum(transactions[*].amount) FROM Inheritx WHERE ANY x IN transactions SATISFIES x.type in [0,4] END;

结果： [ {     ＆＃34; $ 1＆＃34;：null  } ]

现在我想要总结这一切。我该怎么做？

Answer 1

transactions [*]。amount这是返回数组所以首先需要用户数组函数

ARRAY_SUM

比使用下面的总和。

SELECT sum(ARRAY_SUM(transactions[*].amount)) FROM Inheritx WHERE ANY x IN transactions SATISFIES x.type in [0,4] END;
