In Snowflake, the APPLY privilege is required to set a masking policy on a table or view column. This privilege allows a user to associate a masking policy with a specific column, thereby controlling how data in that column is masked or hidden.
Create a Masking Policy: Define a masking policy using the CREATE MASKING POLICY command.
Grant APPLY Privilege: Grant the APPLY privilege on the masking policy to the relevant roles or users.
Apply the Masking Policy: Use the ALTER TABLE or ALTER VIEW command to apply the masking policy to a column.
