You can query esriFieldTypeDate (date-time) fields in two different ways: by DATE or TIMESTAMPdate functions. Setting a definitionExpression on a server-side layer triggers a network request to fetch features that satisfy the definition expression. Query is used to define parameters to filter a layer's features, either by its attributes or its geometry. If you query a layerView when the app loads, then you, If you query a layerView each time the view extent changes, then you. Indicates if the service should cache the query results. It also includes a FeatureLayer created from an array of client-side graphics by setting its source property. The spatial relationship as specified by. The definitions for one or more field-based statistic to be calculated. The ArcGIS API for Python is both an API and a Python package.
