ArcGIS Server REST-Query Layer: only few attribute fileds are returned in response

Question

a newbie question in using ArcGIS Server REST service:

from ArcGIS Services Directory, I opened the page of one layer in a MapServer service, this layer has a long list of attributes/fields. however, in the response of Query_Layer operation, it only includes two attribute fields in each feature object.

I am wondering is this a configurable setting? if so, where to control this to return all attribute fields.

thanks! and let me if further details of this question are needed.

Answer 1

In the Result Options box near the bottom of the page, there is an input for 'Return Fields (Comma Separated)'. Accordingly, you put in a comma delimited list of the fields you want included. Its the same thing for all of the web api's as well, there is a property where you set what fields get returned to the client.

I think by default, it only returns OBJECTID and Display Field.
