Description

It is recommended to set cross db ownership chaining database flag for Cloud SQL SQL Server instance to off.

This flag is deprecated for all SQL Server versions in GCP. Going forward, you cannot set its value to on. However, if you have this flag enabled, we strongly recommend that you either remove the flag from your database or set it to off. For cross-database access, use the Microsoft tutorial for signing stored procedures with a certificate (https://learn.microsoft.com/en-us/sql/relational-databases/tutorial-signing-stored-procedures-with-a-certificate?view=sql-server-ver16).

Rationale

Use the cross db ownership chaining option to configure cross-database ownership chaining for an instance of Microsoft SQL Server. This server option allows you to control cross-database ownership chaining at the database level or allow cross-database ownership chaining for all databases. Enabling cross db ownership is not recommended unless all of the databases hosted by the SQL Server instance must participate in cross-database ownership chaining and you are aware of the security implications of this setting. This recommendation is applicable to SQL Server database instances.

From Google Cloud Console

1. Go to the Cloud SQL Instances page in the Google Cloud Console by visiting https://console.cloud.google.com/sql/instances.
2. Select the SQL Server instance for which you want to enable the database flag.
3. Click Edit.
4. Scroll down to the Flags section.
5. To set a flag that has not been set on the instance before, click Add item, choose the flag cross db ownership chaining from the drop-down menu, and set its value to off.
6. Click Save.
7. Confirm the changes under Flags on the Overview page.

From Google Cloud CLI

1. Configure the cross db ownership chaining database flag for every Cloud SQL SQL Server database instance using the following command:

   gcloud sql instances patch {{instance-name}} \
       --database-flags "cross db ownership chaining"=off

   Note: This command will overwrite all database flags previously set. To keep those and add new ones, include the values for all flags to be set on the instance; any flag not specifically included is set to its default value. For flags that do not take a value, specify the flag name followed by an equals sign ("=").
