Query (Return) All Points In Query Task and Query Object

Question

Using ArcGIS JavaScript API 3.21 I need to grab all Points on a Server. The code works for me with Query.where clause at

query.where = "FeederID = 'RMT001'";

but as I said I need to get all Points. I tried to run the query without any Query.where statement but not getting back anything. can you please let me know how to get all Points?

 function execute () {
 var query = new Query();
 query.where = "FeederID = 'RMT001'";
 query.returnGeometry = true;
 query.outFields = [ "CreationUser", "FName" ];
 queryTask.execute(query, showResults);
 } 

Answer 1

The most common way and which should always work (because it's always true) is 1=1.

query.where = "1=1";

Using OBJECTID as suggested in another answer, will not work for all layers, see for example https://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/incidents_report/FeatureServer/0/ where the "Object ID field" is called FID.

Answer 2

Since you need to get geometries, you can use this query : query.where = "OBJECTID > 0"; Arcgis stores geometries with a unique numerical field
