SqlTrackingQuery provides methods and properties that you can use in order to access certain kinds of tracking data stored in a SQL database by the SqlTrackingService. Access to this data is provided through SqlTrackingWorkflowInstance objects. You can call TryGetWorkflow to try to get a SqlTrackingWorkflowInstance for a specific workflow instance. You can call GetWorkflows to get a collection of SqlTrackingWorkflowInstance objects that correspond workflow instances that have tracking data that matches a set of query parameters contained in a SqlTrackingQueryOptions that is passed as a parameter to the method. See the SqlTrackingWorkflowInstance class for more information about the kind of tracking data available and see the SqlTrackingQueryOptions class for more information about the kind of queries that can be performed.
