Map Services and Joins.

jaykapalczynski — Thu, 05 Mar 2015 14:51:26 GMT

I have access to a basic Map Service. I also have a dataset/table with a bunch of additional information.

Can I join this Map Service with the table, register it in AGO and use it in a AGO template?
In JavaScript API. Can I do this join and then have the data available in my JS App?

Hi Jay,

You will not be able to perform the join to the map service. You will need to perform the join to the actual data. Here is a tool you can use to download the data from the Map Service. Once it's downloaded, you can then join the table to feature class, and then re-publish as a new map service.

Thats what I was figuring....

Question...Can I use this tool for any map service out there....especially one that is not in AGO but on someones own server....I have credentials to view it...can I download it?

I found a sample on github, but it looks like it connects to a File geodatabase.

I don't know how you can relate two map services even if one is a table.
