A developer created a landing page in CloudPages which return unique content when subscriber data is located on a related data extension. The developer does not know if all subscribers have rows in the related data extension, and want default content to render if no subscriber data is found on the related data extension. Which best practice should the developer follow to control the unique and default content?

Show Suggested Answer Hide Answer
Suggested Answer: A

To control the rendering of unique and default content based on the presence of subscriber data in a related data extension, the best practice is to use the RowCount function and an IF statement:

%%[ VAR @rowCount SET @rowCount = RowCount(LookupRows('RelatedDataExtension', 'SubscriberKey', _subscriberKey)) IF @rowCount > 0 THEN /* Render unique content */ ELSE /* Render default content */ ENDIF ]%%

This approach checks if there are any rows in the related data extension for the subscriber and conditionally renders the appropriate content.

I feel like D is too limited. It doesn’t handle unique content well.

Haha, I bet the developer is scratching their head trying to figure out which one is the "best practice." B is the way to go, no doubt.

C) LookupOrderRows and Row functions? Sounds like overkill for this use case. B is the simplest solution.

I’m not entirely sure, but I think the Lookup function might be more appropriate for retrieving specific subscriber data.

I think I'm leaning towards option B. Using the Lookup, Row, and Field functions seems like it would give me the most control and flexibility to handle both the unique and default content.

The DataExtensionRowCount function in option D sounds interesting, but I'm not familiar with that one. I'll have to look into how it works and whether it's the best choice for this scenario.

Option A with the RowCount function and an IF statement could also work, but I'm not sure if that's the most efficient or best practice approach. I'll have to think it through a bit more.
