如何使用 couchbase 查询创建 couchbase 文档的键值对

Question

我正在为我的项目编写 couchbase 查询并在 1 个查询中遇到问题。以下是问题的详细信息。

我有一个名为“workflow”的存储桶，其中几乎没有文档：-

{
     type = "task",
     status = "Completed",
     appId = "72689c67-f5d1-474a-8802-77f332144b12",
     taskNo = 1
},
{
     type = "task",
     status = "Completed",
     appId = "72689c67-f5d1-474a-8802-77f332144b12",
     taskNo = 2
},
{
     type = "task",
     status = "New",
     appId = "72689c67-f5d1-474a-8802-77f332144b12",
     taskNo = 3
},
{
     type = "task",
     status = "New",
     appId = "72689c67-f5d1-474a-8802-77f332144b12",
     taskNo = 4
},
{
     type = "task",
     status = "New",
     appId = "72689c67-f5d1-474a-8802-77f332144b12",
     taskNo = 5
}

我写了一个查询：-

select status, count(*) from workflow where type="task" and appId="72689c67-f5d1-474a-8802-77f332144b12" and status!="" group by status;

结果：-

[
   {
       "$1": 2,
       "status": "Completed"
   },
   {
       "$1": 3,
       "status": "New"
   }
]

预期结果：-

[
    {
        "Completed": 2
    },
    {
        "New": 3
    }
]

有什么办法可以得到预期的结果？任何线索都会非常有帮助。我将免于运行不必要的 for 循环，这将在缩放期间优化我的代码。以及以下声明的任何其他替代方案？

status!=""
