Ouch. I thought you could access simple feature classes from Server, but it seems
as if it can't. Working around that will wander into unsupported realms. How urgent
is your SQL insert requirement?
When I tried to publish an mxd in arcmap 10.2, a dialog box came up saying the table was not registered and the data had to be copied to the server. The words copied to the server make it sound like a one time upload of the data, meaning any inserts after the publication would not be viewable. Maybe I am just misreading the dialog box. Would you explain how you would publish a map service of an unregistered table, so that the sql inserts will be seen after the initial publication?
