There isn't approved info in that table. Those are version and workflow records you are looking for. I wouldn't use the .ExecuteQuery() method as you can use the API for Versioning and Workflow to get that information based on a document or node. I'd suggest downloading the API documentation as it will have what you need. Also check out the API Examples within your local install, you can find examples of how to use the API to get Version and Workflow data.
