The user options option specifies global defaults for all users. A list of default query processing options is established for the duration of a user’s work session. The user options option allows you to change the default values of the SET options (if the server’s default settings are not appropriate).
It is recommended that, user options database flag for Cloud SQL SQL Server instance should not be configured.
Having a single global configuration for users prevents granular options from being assigned to users. Although not directly a security problem, any security related settings that may have been established for specific users are going to be overwritten due to the current misconfiguration. This misconfiguration can potentially lower the overall security of the database instance.
