No workflows are returned when you query workflows by using specific data in the extracts during a user track point in Windows Workflow Foundation

  • Windows Workflow Foundation


Consider the following scenario. You query for workflows by using the SqlTrackingQuery function. You query for the workflows by using specific data in the extracts during a user track point. In this scenario, no workflows are returned.


This problem occurs because Microsoft Windows Workflow Foundation only checks activity event extracts.


To work around this problem, use one of the following methods:

  • Do not use specific data as a query filter when the data is for a user event. Use different filter criteria against the collection that is returned to find the correct instances.
  • Track the data through an activity extract instead of through a user track point.
  • Query the database views directly.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This behavior is by design.
