Can a column be configured for Dynamic Data Masking?
For users without the UNMASK permission, the deprecated READTEXT, UPDATETEXT, and WRITETEXT statements do not function properly on a column configured for Dynamic Data Masking. Adding a dynamic data mask is implemented as a schema change on the underlying table, and therefore cannot be performed on a column with dependencies.
Dynamic data masking helps prevent unauthorized access to sensitive data by enabling customers to specify how much sensitive data to reveal with minimal impact on the application layer. DDM can be configured on designated database fields to hide sensitive data in the result sets of queries.
