我必须 select 类型为组织的所有文档以及数组扩展数据中的任何 "characteristicValue" 是 "M050"。以上是示例文档结构。我如何在一个数组中搜索，该数组也是 couchbase 中另一个数组的一部分？

我试过下面的 N1ql 查询它不起作用。

SELECT *
FROM `contact`
UNNEST contacts.organizationRoles AS roles
WHERE contacts.type = "organization" 
AND ANY extendedData in roles satisfies 
extendeddata.characteristicValue="M050".

根据输出格式，您可以使用以下格式之一。

SELECT *
FROM `contact` AS c
UNNEST c.organizationRoles AS roles
UNNEST roles.extendedData AS e
WHERE c.type = "organization" AND e.characteristicValue = "M050";

SELECT *
FROM `contact` AS c
UNNEST c.organizationRoles AS roles
WHERE c.type = "organization" AND ANY e IN roles.extendedData SATISFIES e.characteristicValue = "M050" END;

SELECT *
FROM `contact` AS c
WHERE c.type = "organization" AND ANY roles IN c.organizationRoles
                              SATISFIES (ANY e IN roles.extendedData
                                         SATISFIES e.characteristicValue = "M050" END) END;
