Question

我是N1QL的新手，我试图在内部联接中查询两个不同的查询但我在下面得到了例外。（重要的是要提到每个查询都是单独测试的 - 它运行得很好）

我的搜索结果如下：

SELECT *
FROM(
  (SELECT payload.masterAdId ,
    SUM(
    CASE
      WHEN payload.active = true
      THEN 1
      ELSE 0
    END) AS numOfActiveversions,
    SUM(
    CASE
      WHEN payload.active = false
      THEN 1
      ELSE 0
    END)    AS numOfDisabledVersions,
    COUNT(1)AS totalVersions
  FROM mvbucket
  WHERE _identifier    = "adsmartversion"
  AND payload.accountId= 1073741826
  GROUP BY payload.masterAdId limit 1
  )A
JOIN
  (SELECT payload.id AS masterAdId ,
    payload.name     AS masterAdName,
    payload.adAssignmentData.campaignId,
    payload.adAssignmentData.campaignName,
    array_count(payload.adSmartVersionSchema.smartElements[].svKey) AS numberofdynamicelements
  FROM DEFAULT
  WHERE payload.massVersioning             = true
  AND payload.adAssignmentData.campaignId IS NOT NULL
  GROUP BY payload.id,
    payload.name,
    payload.adAssignmentData.campaignId,
    payload.adAssignmentData.campaignName,
    array_count((array_star((((default.payload).adSmartVersionSchema).smartElements)).svKey))
  )B
ON keys A.payload.masterAdId);

以及我获得的例外情况：

"errors": [
        {
            "**code": 3000,**
            **"msg": "syntax error - at A"**
        }

所以它似乎是连接结构的东西。是否可以在N1QL中这样做？

知道如何让它正常工作？提前致谢

目前，JOIN的右手术语必须是表/桶。您可以重写查询以在JOIN之后执行右手聚合。
