Database versions and version policies

MySQL | PostgreSQL | SQL Server

This page describes Cloud SQL's database version support policies.

Database versions supported by Cloud SQL

The database engines supported by Cloud SQL include multiple versions. The versions can vary in capabilities and in the types of issues that arise. While performing an upgrade can impact your users, providing up-to-date database features and important patches is also critical. Cloud SQL keeps your instances up-to-date with patches and minor version updates automatically.

Major and minor versions supported by Cloud SQL

Cloud SQL supports the following database versions:

Major version	Minor version	Support start date
SQL Server 2022 Standard	CU12	June 26, 2023
SQL Server 2022 Enterprise	CU12	June 26, 2023
SQL Server 2022 Express	CU12	June 26, 2023
SQL Server 2022 Web	CU12	June 26, 2023
SQL Server 2019 Standard (default)	CU26	June 24, 2021
SQL Server 2019 Enterprise	CU26	June 24, 2021
SQL Server 2019 Express	CU26	June 24, 2021
SQL Server 2019 Web	CU26	June 24, 2021
SQL Server 2017 Standard	CU31	February 19, 2020
SQL Server 2017 Enterprise	CU31	February 19, 2020
SQL Server 2017 Express	CU31	February 19, 2020
SQL Server 2017 Web	CU31	February 19, 2020

Cloud SQL database version format

For SQL Server, the year provides the major version number and the minor version is the supported Cumulative Update (CU). For example, for SQL Server 2022 Enterprise CU11, 2022 Enterprise is the major version number and CU11 is the minor version number.

How to identify the database version of your Cloud SQL instance

You specify the database version when you create a Cloud SQL instance. If you don't specify a database version, then Cloud SQL uses the default database version.

To view the database version of a Cloud SQL instance, do the following:

In the Google Cloud console, go to the Cloud SQL Instances page.

Go to Cloud SQL Instances
To open the Overview page of an instance, click the instance name.
In the Configuration card, view the Database version.

To filter instances by a specific database version within your Cloud SQL project, do the following:

In the Google Cloud console, go to the Cloud SQL Instances page.

Go to Cloud SQL Instances
In the Filter field, select Type. The database versions that are within your project are listed.
to filter the instances Select a database version within your project.

To view all Cloud SQL instances and their database versions in your organization, use Database Center. You can also switch views in Database Center from project to folders or organizations to get a complete list of all your Cloud SQL instances. For more information, see Filter resources and export fleet inventory information.

Minor version support

Cloud SQL supports new minor versions within three months of their general availability release by the database engine developer community. After Cloud SQL supports a new minor version, Cloud SQL provisions new instances on the new version automatically. During the next scheduled maintenance rollout, Cloud SQL upgrades existing instances to the new version.

Cloud SQL determines the target minor version for each database engine. When the target minor version is different from the minor version for a Cloud SQL instance, Cloud SQL upgrades that version during the next maintenance cycle. You can control the day and time when maintenance restarts occur by setting a maintenance window for your instance.
