I was wondering if this was possible to join 2 attribute tables from 2 different geodatabases. I have a feature class in 1 geodatabase and another feature class in a different geodatabase. I would like to join the attribute tabels.
Are you planning to use this join in a service used in a web app as I don't believe that workflow is supported?
If I were using ArcPRO I would add both databases (right click on databases, click add database) , then add to current map, and then join with a common field.
