How can MongoDB query results be returned as a value list only?

 May 12, 2019   mongodb, question

Can you not display key

Json is originally unordered and needs a key to identify the attribute. If there is no key, the attribute of the value cannot be determined, so this function will not appear again.
Your needs are more suitable at the business end.
