Severity

Low

Some parts of the output code are omitted for clarity reasons.

Description

This EWI is added when the Alter Table statement contains a MASKED WITH clause. The reason this is added is to inform that an approximate MASKING POLICY was created as a substitute for the MASKED WITH function.

Code Example

Input Code:

IN -> SqlServer_01.sql

ALTER TABLE table_name
ALTER COLUMN column_name
ADD MASKED WITH (FUNCTION = 'default()');

Output Code:

OUT -> SqlServer_01.sql

--** SSC-FDM-TS0022 - MASKING ROLE MUST BE DEFINED PREVIOUSLY BY THE USER **
CREATE OR REPLACE MASKING POLICY "default" AS
(val STRING)
RETURNS STRING ->
CASE
WHEN current_role() IN ('YOUR_DEFINED_ROLE_HERE')
THEN val
ELSE 'xxxxx'
END;

ALTER TABLE IF EXISTS table_name MODIFY COLUMN column_name/*** SSC-FDM-TS0021 - A MASKING POLICY WAS CREATED AS SUBSTITUTE FOR MASKED WITH ***/  SET MASKING POLICY "default";

The MASKING POLICY will be created previous to the ALTER TABLE statement. And it is expected to have an approximate behavior. Some tweaks might be needed in regard to roles and user privileges.
