A query widget allows you to run predefined queries about the features in the map. When you open an operation view that includes a query widget, the widget displays a list of its queries.
The results of the query are static. This means that as the data source is updated, the query results do not change as the data changes. They represent a snapshot of the data at the time the query was executed. The Last executed date/time indicates when the query was run so you can tell how up-to-date the results are. To update the results, you can reexecute the query.
