QueriableDataSource | ArcGIS Experience Builder

Interface

QueriableDataSource extends DataSource and add query capability. A queriable data source must have an URL to execute the query.

The current default query implementation supports pagination. It allows multiple widgets to apply queries on the same data source, all of which are merged by using the AND logic operator.

When execute a query, in addition to the passed in query parameters, all configured queries and all other widgets applied queries are merged by using the AND logic operator.

When a query is executed against a data view, the query from its main data source is used as well.
