Finding a masked column in a table

If the table belongs to a database, then in the context of the database run the query:

SELECT * FROM sys.columns

If the column(s) is masked you should look for the column 'is_masked' in the response as shown.


Here is an example. The FirstName column in the Employees table in Northwind database is masked using the default masking function. When you run the above query this is what you will see.
