I am connecting to a SQL Server 2016 database, and adding data into ArcMap 10.3.1 as a Query Layer.
I want to publish this data as a Feature Access service to ArcGIS Server 10.3.1. I have no problems publishing this data as a mapping service. However, when I want to enable Feature Access, I get 00223: Query layer has virtual column error.
I have read the documentation on this error, and the only solution is to "Change the query definition of your layer so it no longer contains a virtual column or columns".
I have tried several different ways to alter the sql query (very simple queries), and all still produce this same error.
What is a virtual column? How can I publish a Query Layer as a Feature Access service?
