Yesterday's Question of the Day (by Steve Jones - SSC Editor) |
Bypassing Dynamic Data Masking I am using Dynamic Data Masking to limit access to the last four digits of an ID number for customer service personnel. I want a manager to be able to see the entire field for a table. What permission to do I assign and at what scope?
Answer: GRANT the UNMASK permission on the database to the user/role Explanation: The UNMASK permission is only set at the database level to view the information that is masked.
