Is there a way to create a query that retrieves all documents without a value, whether it be null or ''?
Within my table are three documents, each containing a field called a.
https://i.sstatic.net/FGV0Z.png
During an IN query, the document with the null value is not being returned. Is this the intended behavior? How can I ensure that null values are also included in the results?
Is this behavior what you expected?
Indeed, that is the anticipated behavior. Why? The reason being that when passing a list, it should consist of objects. An empty string qualifies as an object, but null does not. Therefore, one cannot anticipate returning documents where a holds the value null when utilizing the in operator. A possible solution would involve employing an OR query, or alternatively, using a simple where statement:
.where("a", "==", null)
This can be combined with another where statement using an in operator, but without including null within the list.
