Issue with Arcade FeatureSetByRelationshipName

bjbertke — Mon, 25 Oct 2021 16:33:26 GMT

I am having trouble using the Arcade Data Function FeatureSetByRelationshipName() It seems that the function is not returning a FeatureSet that can be used by thte Count() function. I am using ArcGIS Pro v2.6.4 and it seems to work against a File Geodatabase but not for an Enterprise Geodatabase. I get an error on the line calling the Count() saying "Array type expected" ... Has anyone seen this or have any suggestions? var attachments = FeatureSetByRelationshipName($feature, 'rel_Structure_Attachments', ['globalid'], false); if (Count(attachments) > 0) { return "Relationships were found." } else { return "No relationship were found." }

There's actually a separate function for working with attachments. Have you attempted to use that?

Even though the attachments are technically a related table, I don't think the application treats it as such.

If you want to get attachments from an attachment table created by the EnableAttachments tool, then you should use the Attachments() function (as Josh said).

If your attachments are from a table created by a user, then I'd guess the problem is that you try to store the result of FeatureSetByName into a reserved variable name (Attchments). Try this:

// the name attachments is reserved for the Attachments() function var attach = FeatureSetByRelationshipName($feature, 'rel_Structure_Attachments', ['globalid'], false); if (Count(attach) > 0) { return "Relationships were found." } else { return "No relationship were found." }
