6.3.1 Set 'external scripts enabled' database flag for Cloud SQL on SQL Server instance to 'off' (Automated)

Profile Applicability

• Level 1


Best practices recommend setting external scripts enabled database flag for Cloud SQL on SQL Server instance to off


external scripts enabled enable the execution of scripts with certain remote language extensions. This property is OFF by default. When Advanced Analytics Services is installed, setup can optionally set this property to true. As the External Scripts Enabled feature allows scripts external to SQL such as files located in an R library to be executed, which could adversely affect the security of the system, hence this should be disabled.This recommendation is applicable to SQL Server database instances.


Setting custom flags via command line on certain instances will cause all omitted flags to be reset to defaults. This may cause you to lose custom flags and could result in unforeseen complications or instance restarts. Because of this, it is recommended you apply these flags changes during a period of low usage.


From Console:

  1. Go to the Cloud SQL Instances page in the Google Cloud Console by visiting
  2. Select the instance to open its Instance Overview page
  3. Ensure the database flag external scripts enabled that has been set is listed under the Database flags section.

From Command Line:

  1. Ensure the below command returns off for every Cloud SQL SQL Server database instance
gcloud sql instances list --format=json | jq '.settings.databaseFlags[] | select(.name=="external scripts enabled")|.value'


From Console:

  1. Go to the Cloud SQL Instances page in the Google Cloud Console by visiting:
  2. Select the SQL Server instance for which you want to enable to database flag.
  3. Click Edit.
  4. Scroll down to the Flags section.
  5. To set a flag that is new to the instance, click Add item, choose the flag external scripts enabled from the drop-down menu, and set its value to off.
  6. Click Save to save your changes.
  7. Confirm your changes under Flags on the Overview page.

From Command Line:

  1. Configure the external scripts enabled database flag for every Cloud SQL on SQL Server database instance using the below command.
gcloud sql instances patch <instance_name> --database-flags "external scripts enabled=off"

This command overwrites all database flags previously set. To keep those and add new ones, include the values for all flags you want set on the instance; any flag not specifically included uses the default value. For flags that do not take a value, specify the flag name followed by an equals sign ("=").


Additional Information


This patch modifies database flag values, which may require you to restart your instance. The list of supported flags is on this page, along with details of which flags require a restart:


Some database flag settings can affect instance availability or stability, and remove the instance from the Cloud SQL Service-Level Agreement (SLA). For information about these flags, see Operational Guidelines.


Configuring the preceding flag does not restart the Cloud SQL instance.
