Notice how the results are returned as GeoJSON this time. Query expressions are used in ArcGIS to select a subset of features and table records. For example, you use this syntax using the Select By Attributes tool or with the Query Builder dialog box to set a layer definition query. However, you can define multiple queries for a single app, and data layers can be from multiple sources. These tools calculate total counts, lengths, areas, and basic descriptive statistics of features and their attributes within areas or near other features. ArcGIS for Desktop.
