How to add a list of "permitted values" to a parameter by using a BigQuery connector in Data Studio?

I was wondering if there is a way to add a list of "permitted values" to a parameter in Data Studio by using a custom query / BigQuery connector?

There is an option to do it manually in the Data Studio UI: Permitted values through Data Studio UI

But I am looking for a solution to do it through SQL because I have to pass a long list of values that can be changed every day, so adding a list of values manually through the UI is impossible.

Is it possible to do it through a custom query?

Thank you!

You can add parameters to a custom SQL query in the connector, just like the following examples show

    SELECT word FROM `TABLE` WHERE corpus = @corpus;
    
    Use a string with contains and a number:
    
    SELECT * FROM `bigquery-public-data.baseball.games_post_wide`
    
    WHERE REGEXP_CONTAINS(gameId, @s)
    
    AND attendance > @attendance LIMIT 100;

    
    Use a multi-select string parameter. Note the use of UNNEST to flatten the list of values:
    
    SELECT * from user.users as user WHERE display_name in UNNEST(@name);

    
    Date parameter example:
    
    SELECT creation_date, age, display_name from user.users as user
    
    WHERE creation_date > PARSE_DATE('%Y%m%d', @DS_START_DATE)
    
    AND creation_date < PARSE_DATE('%Y%m%d', @DS_END_DATE);

    
    Email parameter example:
    
    Select * from Sales WHERE sales-rep-email = @DS_USER_EMAIL;

You do not need a custom query to define allowed Values if you want to Filter for them just set them up as a Dimension and add a Filter Control with an drop-down List. This will allow you to select the present Values and filter for them.

Let me know if this solves it for you
