Yesterday's Question of the Day (by Steve Jones - SSC Editor) |
Default Masking I have a 20 character varchar string column in a table. I want to add dynamic masking to the column with this code: ALTER TABLE dbo.DDMTest ALTER COLUMN String1 ADD MASKED WITH (FUNCTION='DEFAULT()'); I have two rows with values in this string column. One row has 1 character, one has 5 characters. If a user queries these rows without the UNMASK permission, how many Xs will appear for the 1 character string and the 5 character string? Answer: 4 Xs for 1 character and 4 Xs for 5 characters Explanation: The default mask will return 4 Xs for a field length that's greater than 4 characters.
