Equivalent of Group By on a Structure?

Is there anything like the equivalent of a Group By that you can apply to a Structure as the List Filter doesn't achieve that?  Of course I can loop round the List to extract the unique attributes but I wondered if there was anything inbuilt.

You may have to loop the list, if not Group by

Hi Sienna,

You have a set of built-in functions that can be useful: https://success.outsystems.com/Documentation/11/Reference/OutSystems_Language/Data/Data_Types/List

But none will do exactly the same thing as a group by in SQL... 

You can also take a look in the Forge, as I think there are a few extensions that can help more, like this one: https://www.outsystems.com/forge/component-overview/1293/dynamic-linq


I still can't see anything that would work similar to a Group By for a List.  Oh well nevermind, I will just have to do it myself.  Thanks anyway though!
