Query as a source in Parameter - How to?

Hey Anonymous ,

here https://docs.microsoft.com/en-us/power-query/power-query-query-parameters#creating-query-parameters you will find this little sentence "and then restrict the acceptable values for that parameter to a static list of Text values". The static list is the query. To have this option available it's necessary to first create a list.

In the query editor you can create a very simple list by adding a Blank Query:

in the "Advanced Editor"

Replace everything with this code:

let
    Source = {"a", "b"}
in
    Source

And you will have created your first list

Beware of the different icon 😉

Now you use this list as input for the query.

Hopefully, this is what you are looking for.

Regards,

Tom
