SQL, being a widely used language for managing and querying databases, has evolved through numerous versions and editions, each offering different features, performance enhancements, and security updates. Identifying the version helps you leverage the right functionalities and maintain optimal system performance. Moreover, it plays a key role in ensuring that your applications and tools are compatible with the database environment.

In this article, we’ll explore the various ways to determine your SQL version quickly and accurately. By gaining clarity on this topic, you’ll be better equipped to manage your databases effectively and make informed decisions about upgrades and maintenance. Let’s dive into the essentials of how to know the SQL version you’re working with.

Checking SQL Version Using SQL Queries

One of the most direct methods to determine the SQL Server version is by executing specific SQL queries. These queries retrieve system information, including the exact version and edition of the SQL Server instance.

A commonly used query is:

“`sql
SELECT @@VERSION;
“`

This returns a string containing detailed information about the SQL Server version, operating system, and build number. However, the output can be verbose and may require parsing to extract specific details.

For more structured information, you can query the `SERVERPROPERTY` function. This function allows you to retrieve specific properties about the SQL Server instance, such as the product version, product level, and edition.

Examples include:

“`sql
SELECT
SERVERPROPERTY(‘ProductVersion’) AS ProductVersion,
SERVERPROPERTY(‘ProductLevel’) AS ProductLevel,
SERVERPROPERTY(‘Edition’) AS Edition;
“`

`ProductVersion` returns the version number in the format `major.minor.build.revision` (e.g., `15.0.2000.5`).
`ProductLevel` indicates the service pack or cumulative update level (e.g., `RTM`, `SP1`).
`Edition` specifies the edition of SQL Server (e.g., `Enterprise Edition`, `Standard Edition`).

These queries provide a precise and easily readable format for identifying the SQL Server version and related details.

Using SQL Server Management Studio (SSMS) Interface

If you prefer a graphical approach, SQL Server Management Studio offers several ways to view the SQL Server version without writing queries.

– **Object Explorer**: Connect to the SQL Server instance, and right-click the server name at the top of Object Explorer. Select **Properties**. In the **General** tab, the product version and edition are displayed.

– **Help Menu**: Within SSMS, navigate to **Help > About**. This dialog lists all installed components, including the version of SQL Server Management Studio and the connected server version.

Connect to Server Dialog: When connecting to a SQL Server instance, the version number is sometimes displayed beside the server name in the dropdown list, depending on the SSMS version.

Using SSMS provides a user-friendly method to quickly ascertain the SQL Server version, especially for administrators who prefer visual tools over command-line queries.

Identifying SQL Version via Command Line Tools

For environments where GUI tools are unavailable or when scripting is preferred, command line utilities can be used to check the SQL Server version.

sqlcmd Utility: This command-line tool allows execution of SQL commands directly against the server. Run the following command:

“`bash
sqlcmd -S -Q “SELECT @@VERSION”
“`

Replace `` with the target SQL Server instance. The output will display the full version string.

PowerShell: Using PowerShell, you can connect to SQL Server and retrieve version information. For example:

“`powershell
Invoke-Sqlcmd -Query “SELECT SERVERPROPERTY(‘ProductVersion’), SERVERPROPERTY(‘ProductLevel’), SERVERPROPERTY(‘Edition’)” -ServerInstance “”
“`

This method is useful for automation and integrating version checks into scripts or monitoring tools.

Interpreting SQL Server Version Numbers

Understanding the version number format helps in identifying the exact release and update level of SQL Server. The version number typically follows the pattern:

`major.minor.build.revision`

Component	Description	Example
Major	Main version number	15 (SQL Server 2019)
Minor	Minor release number	0
Build	Build number indicating updates	2000
Revision	Revision or hotfix identifier	5

For instance, version `15.0.2000.5` corresponds to SQL Server 2019 RTM.

Microsoft provides a detailed list of build numbers and their corresponding SQL Server versions and updates. This can be referenced to determine if a server is running the latest service pack or cumulative update.

Checking Version Information for Other SQL Database Systems

While the methods described above focus on Microsoft SQL Server, other SQL database systems have their own commands to check version information.

MySQL:

“`sql
SELECT VERSION();
“`

PostgreSQL:

“`sql
SELECT version();
“`

Oracle:

“`sql
SELECT * FROM v$version;
“`

Each database system returns version information in a unique format but generally includes the major release, minor release, and patch level. Understanding these commands is essential when working in multi-database environments.

Summary of Common SQL Version Retrieval Commands

Database System	Command to Check Version	Output Type
Microsoft SQL Server	`SELECT @@VERSION;`	String with version and build details
Microsoft SQL Server	`SELECT SERVERPROPERTY('ProductVersion');`	Version number only
MySQL	`SELECT VERSION();`	Version string
PostgreSQL	`SELECT version();`	Version string with build info
Oracle	`SELECT * FROM v$version;`	Multiple rows with component versions

Determining the SQL Server Version Using T-SQL Commands

To identify the version of a Microsoft SQL Server instance, several Transact-SQL (T-SQL) commands can be executed. These commands provide detailed information about the server’s version, edition, build number, and service pack level.

Using the @@VERSION function: This built-in function returns a single string containing the complete SQL Server version information, including the OS details.
Executing SERVERPROPERTY(): This function allows retrieving specific properties related to the SQL Server instance, such as product version and edition.
Querying sys.dm_os_server_diagnostics_log_config: For diagnostic purposes, this DMV can sometimes provide insights into the server environment, although it is less commonly used for version checking.

Command	Description	Example Output
`SELECT @@VERSION;`	Returns a string with the SQL Server version, OS version, and build date.	Microsoft SQL Server 2019 (RTM) – 15.0.2000.5 (X64) Sep 24 2019 13:48:23 Copyright (C) 2019 Microsoft Corporation
`SELECT SERVERPROPERTY('ProductVersion');`	Returns the version number of the SQL Server instance (e.g., 15.0.2000.5).	15.0.2000.5
`SELECT SERVERPROPERTY('ProductLevel');`	Returns the service pack level or update applied (e.g., RTM, SP1, CU3).	RTM
`SELECT SERVERPROPERTY('Edition');`	Returns the edition of SQL Server (e.g., Enterprise Edition, Standard Edition).	Enterprise Edition (64-bit)

These commands can be run within SQL Server Management Studio (SSMS) or any other query tool connected to the SQL Server instance.

Checking SQL Version via SQL Server Management Studio (SSMS)

SQL Server Management Studio provides a graphical way to view the version and edition of the connected SQL Server instance without running queries.

Connect to the SQL Server instance: Open SSMS and connect to the target server.
