Sql n1ql-查询两个不同查询的内部联接

我是N1QL新手，我试图为两个不同的查询查询一个内部联接，但我得到以下异常。（值得一提的是，每个查询都是单独测试的，而且效果很好）

我运行的查询如下所示：

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);

我得到的例外是：

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);

因此，它似乎与连接结构有关。在N1QL中是否可以这样做

你知道我怎样才能让它正常工作吗？

提前感谢

当前，联接的右侧术语必须是表/桶。您可以重写查询以在联接后执行右侧聚合

目前，右侧必须是桌子/桶。您可以在加入后执行右侧聚合。谢谢！！！我们将努力做到这一点。
