Dataview metadata from properties

[ashish]

I am trying to build a simple dataview query based on the newly released properties.

Here is my frontmatter:

due and scheduled are dates, effort is a list and done is a checkbox type.

How can I list the notes with done unchecked?

This is what I tried, and it doesn’t work:

LIST
FROM "Tasks"
WHERE done = null

Tasks is the folder where these notes are placed.

unchecked value is false, not null.

unentered values (new, never having been clicked) are null.
a false value has been intentionally entered.
If your checkbox is in a template, you can set the default value to false
or your query could be, e.g.:

LIST
FROM “00.03 schedule”
WHERE finished = false OR finished = null
