Create a calculated column using beast mode



I would like to calculate the following using beast mode, having the results in a new column.


column name: Start Date "9/1/2019"

column name: Days Ago "2"

If column "days ago" has a number in it, then take the date in the "start date" column and subtract it from the number in column "days ago"; resulting in the new "activity date". 

If column "days ago" is null (has no data), the result is: "start date"

New column is: Activity Date


Any assistance is greatly appreciated.

    Another option (assuming it will be either a number or null) is to utilize COALESCE or IFNULL function:


    DATE_SUB(`Start Date`, interval COALESCE(`Days Ago`, 0) day)

    You could do this a couple different ways, but here is one for you:

    CASE WHEN 'Days Ago' >= 1 THEN
         DATE_SUB('Start Date', interval 'Days Ago' day)
        'Start Date'


    Hope this helps. 

  • Hello @Hulachic5 & @MarkSnodgrass ,

    I love the work you've done with Beast Modes. I'm happy to let you know we have just released Code Block apps in our Domo Appstore. These allow customers and Domo experts such as yourself, to publish code blocks like the ones you've created for distribution in the Appstore. The publish process for the code blocks is currently in an early beta. If you are interested in publishing your code blocks, let me know and we can enable it for you.
