public class QueryDataSource
extends com.google.gwt.core.client.JavaScriptObject

Class added v2.7 The QueryDataSource class defines and provides information about a layer or table that is defined by a SQL query. The geometry storage format determines the capabilities of the QueryDataSource. If the data source stores the geometry in the database native format the return value is a layer that supports all operations supported by a dynamic layer. If the data source stores geometry in a non-native format the result is a table that can be used to perform query operations.
