WINBIO_E_DATABASE_NO_RESULTS
WINBIO_E_DATABASE_NO_RESULTS means a database query completed successfully but found no matching records. It does not mean that the storage adapter or sensor failed.
What to check
- Verify the query criteria, selected database, and identity scope.
- Use the result to decide whether enrollment is needed rather than retrying the same query indefinitely.
- For an application, distinguish this state from I/O errors and surface it as “no enrollment found.”
