By the end, you’ll be equipped with the knowledge to confidently verify your SQL version, setting a solid foundation for effective database management and development.

Checking SQL Server Version Using SQL Queries

One of the most straightforward methods to determine the version of your SQL Server instance is by executing specific SQL queries. These queries return detailed information about the SQL Server edition, version number, build number, and service pack level.

The most commonly used queries include:

`SELECT @@VERSION;`

This returns a single string containing version details, including the SQL Server version, operating system information, and build number.

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

This query provides more granular details:

`ProductVersion`: Displays the exact version number (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, Standard).

Using these queries is especially useful for automated scripts or when you need to log version details programmatically.

Using SQL Server Management Studio to Identify Version

SQL Server Management Studio (SSMS) offers a graphical interface that simplifies checking the server version without running queries manually. After connecting to the desired SQL Server instance, you can find version information in several ways:

– **Object Explorer Header**: Once connected, the Object Explorer’s root node displays the server name followed by the version number in parentheses.

– **Properties Window**: Right-click the server instance in Object Explorer and select “Properties.” The “General” page shows the version and edition under the “Product” field.

– **About Dialog**: From the SSMS menu, go to `Help > About`. This dialog lists the installed components and the version of SSMS itself, which may help correlate client tools with the server version.

These methods provide a quick, user-friendly approach to version identification and are suitable for administrators who prefer GUI tools.

Checking SQL Version Through Command Line Tools

For environments where GUI tools are unavailable or when using automated deployment scripts, command line utilities provide alternative ways to check SQL Server versions.

sqlcmd Utility: This command-line tool allows you to execute SQL commands directly. To check the version, use:

“`
sqlcmd -S -Q “SELECT @@VERSION;”
“`
Replace `` with the target server instance. This will output the version information directly in the console.

PowerShell: SQL Server version can be queried using PowerShell by invoking SQL commands:

“`powershell
Invoke-Sqlcmd -Query “SELECT SERVERPROPERTY(‘ProductVersion’), SERVERPROPERTY(‘Edition’)” -ServerInstance “”
“`
This method integrates well with scripting and automation frameworks.

These tools are especially useful for remote management or batch operations across multiple servers.

Interpreting SQL Server Version Numbers

Understanding the version number returned by SQL Server is essential to identify the exact release and compatibility level. The version number typically consists of four parts separated by dots (e.g., 15.0.2000.5):

The major version indicates the SQL Server release (e.g., 15 corresponds to SQL Server 2019).
The minor version is often zero but can indicate service updates.
The build number identifies specific updates or patches.
The revision number provides incremental fixes.

Below is a table summarizing major SQL Server versions and their corresponding major version numbers:

SQL Server Version	Major Version Number	Release Year
SQL Server 2019	15	2019
SQL Server 2017	14	2017
SQL Server 2016	13	2016
SQL Server 2014	12	2014
SQL Server 2012	11	2012
SQL Server 2008 R2	10.50	2010
SQL Server 2008	10.0	2008

By matching the major version number from your query results with this table, you can quickly identify the SQL Server version installed on your system.

Checking Version for Other SQL-Based Databases

While the above focuses on Microsoft SQL Server, checking version information varies across other popular SQL-based databases:

MySQL/MariaDB: Use the query `SELECT VERSION();` or check via the command line with `mysql –version`.

PostgreSQL: Execute `SELECT version();` or run `psql –version` in the terminal.

Oracle Database: Query `SELECT * FROM v$version;` or use `sqlplus -v` from the command line.

SQLite: Use the command `sqlite3 –version` in the terminal or query `SELECT sqlite_version();` within the database.

Each database management system (DBMS) provides specific commands or queries to obtain version details, which are crucial for compatibility, troubleshooting, and upgrade planning.

How To Check Version Of SQL Server

Determining the version of your SQL Server instance is essential for compatibility, troubleshooting, and maintenance tasks. SQL Server provides several straightforward methods to retrieve version details, including the exact build number and edition.
