如何在同一查询中使用 DISTINCT 和 VALUE？

Question

我试图从以下查询中获取仅包含值的数组

SELECT DISTINCT c.Section
FROM c
WHERE c.brand = 'monki'
AND c.Consumer = 'Storelens_V2'

所以我改成了这个

SELECT DISTINCT VALUE c.Section
FROM c
WHERE c.brand = 'monki'
AND c.Consumer = 'Storelens_V2'

但这给出了错误

Failed to query item for container formatteddata:
 Cannot set property 'headers' of undefined

如何同时使用 distinct 和 Value？

Answer 1

SELECT DISTINCT VALUE(c.Section)
FROM c
WHERE c.brand = 'monki'
AND c.Consumer = 'Storelens_V2'

Answer 2

很奇怪，通过过滤掉空值这个查询有效，我真的不明白为什么只是简单地添加一个 where 子句 where distinct_property != null 直接解决了问题

How can I use DISTINCT and VALUE in same query?
