SQL Server version 17 is SQL Server 2025, version 16 is SQL Server 2022, version 15 is SQL Server 2019 and version 14 is SQL Server 2017; run SELECT @@VERSION to see which build you have.
This list maps every major version number to its release, with RTM and latest builds, support end dates, and the upgrade path from version 15 to 16.
What version of SQL Server do I have?
Connect to the instance in SQL Server Management Studio or any query tool and run one query. The output names the release, the cumulative update level, the build number and the edition.
SELECT @@VERSIONReturns one string with the product name, update level, KB number, build number, architecture, edition and the operating system SQL Server runs on.
You should see: A line such as Microsoft SQL Server 2022 (RTM-CU14) (KB5038325) – 16.0.4135.4 (X64) … Developer Edition (64-bit). The first number of the build (16) is the major version; match it in the summary table below.
Version numbers follow the major.minor.build.revision pattern, and the revision part is normally ignored when you identify a release.
Quick summary: SQL Server version numbers and support dates
Match the first part of your build number to the release in this table, which gives the version details for every release in one place. Latest builds are current as of the October 2026 security release.

How to read a SQL Server build number
A build number such as 16.0.4135.4 has four parts: major.minor.build.revision. Read them left to right to name the release and its update level.
| Part | Example | What it tells you |
|---|---|---|
| Major version | 16.0.4135.4 | The release: 17 is 2025, 16 is 2022, 15 is 2019, 14 is 2017, 13 is 2016 |
| Minor version | 16.0.4135.4 | Almost always 0; SQL Server 2008 R2 uses 50, which separates it from SQL Server 2008 (10.0) |
| Build | 16.0.4135.4 | The servicing branch and update level: the lowest build is RTM, low builds close to it are the security-only GDR branch, and higher builds are the cumulative update branch |
| Revision | 16.0.4135.4 | Normally ignored when you identify a release |
On SQL Server 2019, for example, GDR builds run 15.0.2xxx and cumulative update builds run 15.0.4xxx, so 15.0.2200.2 and 15.0.4500.2 are both October 2026 security releases on different branches. The sqlservr.exe file version writes the same build with the year in front, such as 2019.150.4430.1 for build 15.0.4430.1.
Microsoft SQL Server 2025 builds
SQL Server 2025 is version 17.0, released to manufacturing on November 18, 2025. Builds starting 17.0.1xxx are the GDR (security-only) branch; 17.0.4xxx and 17.0.5xxx are the cumulative update branch.

The table mixes two servicing branches. Cumulative update (CU) builds start 15.0.4xxx and add fixes on top of the previous CU; General Distribution Release (GDR) builds start 15.0.2xxx and carry security fixes only for an instance that never took a CU. Microsoft removed CU7 (15.0.4063.15), so skip that build if an old installer still offers it.
The SQL Server 2019 release notes list known issues worth checking before you install: Setup can fail from removable media when SSMS 18.0 to 18.3 is already installed (uninstall the older SSMS and install the latest first), and on Windows Server 2025 SQL Server can hit access violations when the Lock pages in memory policy is enabled for its service account.

Other ways to check the SQL Server version and edition
SELECT @@VERSION covers most cases, but these routes help when you cannot run a query or need every instance on a machine.
| Your situation | Use this | What you see |
|---|---|---|
| Already connected in SSMS | Object Explorer | The version in parentheses next to the server name |
| Need individual values for a script | SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY('productlevel'), SERVERPROPERTY('edition') |
Separate columns, for example 16.0.4135.4, RTM, Developer Edition (64-bit) |
| Cannot connect to the instance | The first lines of the ERRORLOG file in the instance's MSSQL\LOG folder | Product, update level, build, edition and OS |
| Several instances on one server | Installed SQL Server features discovery report on the Tools page of the SQL Server Installation Center | Every local instance and client tool; it cannot read remote servers |
If you do not have the management tools yet, SQL Server Management Studio is a free download from Microsoft.
How to upgrade SQL Server version 15 to 16
SQL Server 2022 (version 16) supports an in-place upgrade from SQL Server 2019 (version 15), 2017, 2016 SP3, 2014 SP3 and 2012 SP4. Back up every database first, and clear any pending restart, because Setup blocks the upgrade if one is waiting.
SQL Server 2022 is 64-bit only, so a 32-bit instance cannot be upgraded in place; back up or detach its databases and restore them on a new 64-bit instance instead.
- Run SQL Server 2022 Setup to open the SQL Server Installation Center.
- Select Installation, then select the Upgrade from option for previous versions of SQL Server.
- On the Product Key page, choose a free edition or enter your product key.
- On the License Terms page, select I accept the license terms and select Next.
- Wait for Upgrade Rules to pass, then on Select Instance pick the version 15 instance to upgrade.
- Review the preselected features on Select Features and the service accounts, then select Next.
- On Ready to Upgrade, select Install, then select Close on the Complete page.
- Run
SELECT @@VERSIONand confirm the build now starts with 16.0.
After the upgrade, install the latest cumulative update for 2022 so the instance does not stay on the RTM build. Installation media is on Microsoft's site, and the SQL Server download options include free Developer and Express editions.

Run SQL Server 2022 Setup, select Installation, then Upgrade from a previous version of SQL Server, and pick your 2019 instance. Back up databases first and make sure no restart is pending, because Setup blocks the upgrade otherwise.
Which SQL Server version should you run?
Run SQL Server 2022 or 2025 for new deployments, and plan the move off SQL Server 2019 or older before their extended support dates. Versions 16 and 17 have mainstream support into 2028 and 2031, while 2019 already receives security fixes only and 2016 and earlier are out of support without paid Extended Security Updates.
