  • Upgrade Planning: Planning an upgrade requires knowing your current version to determine the best upgrade path and ensure a smooth transition.

Method 1: Using SQL Server Management Studio (SSMS)

SQL Server Management Studio (SSMS) is a graphical tool provided by Microsoft for managing SQL Server. It's a user-friendly way to check your SQL Server version. If you're already using SSMS, this is likely the easiest and fastest method.

Step-by-Step Guide

  1. Open SQL Server Management Studio (SSMS): Launch SSMS from your start menu or desktop shortcut. Make sure you have the necessary credentials to connect to your SQL Server instance.
  2. Connect to Your SQL Server Instance: In the Connect to Server dialog box, enter the server name, select the authentication method, and provide your credentials. Click "Connect" to establish the connection.
  3. Check the Server Properties: Once connected, right-click on the server name in the Object Explorer pane. Select "Properties" from the context menu. A Server Properties window will appear.
  4. Locate the Version Information: In the Server Properties window, look for the "Version" field. This field displays the full version number of your SQL Server instance. You can also find additional information such as the product edition and operating system details.

Example

Let's say the "Version" field shows Microsoft SQL Server 2019 (RTM-CU22) - 15.0.4280.1. This tells you that you're running SQL Server 2019, specifically Cumulative Update 22.

Pros and Cons

  • Pros:
    • User-friendly interface.
    • Provides additional server information.
    • No need to execute any queries.
  • Cons:
    • Requires SSMS to be installed.
    • Might not be accessible in all environments.

Method 2: Using T-SQL Query

If you prefer using queries or need to check the version programmatically, T-SQL provides several ways to retrieve the SQL Server version. This method is versatile and can be used in scripts or applications.

Option 1: Using @@VERSION

The @@VERSION global variable returns a string containing detailed information about the SQL Server version, build number, and operating system. It's the most common and straightforward way to get the version.

Step-by-Step Guide

  1. Open a New Query Window: In SSMS, right-click on your database and select "New Query" to open a new query window.
  2. Execute the Query: Type SELECT @@VERSION; in the query window and click the "Execute" button or press F5.
  3. Review the Results: The results pane will display a single row with the version information. The output will be a string that includes the SQL Server version, build number, and operating system details.

Example

The output might look something like this:

Microsoft SQL Server 2019 (RTM-CU22) - 15.0.4280.1 (X64) Jul 16 2023 14:32:07 Copyright (C) 2019 Microsoft Corporation Enterprise Edition (64-bit) on Windows Server 2019 Standard 10.0 <X64> (Build 17763: )

Pros and Cons

  • Pros:
    • Simple and quick.
    • Can be used in scripts and applications.
    • No special permissions required.
  • Cons:
    • Returns a string that needs to be parsed for specific information.

Option 2: Using SERVERPROPERTY()

The SERVERPROPERTY() function provides specific properties of the SQL Server instance, including the version. This function allows you to retrieve individual components of the version information, such as the product version, product level, and edition.

Step-by-Step Guide

  1. Open a New Query Window: In SSMS, right-click on your database and select "New Query" to open a new query window.

  2. Execute the Query: Use the SERVERPROPERTY() function to retrieve the desired version properties. Here are some useful properties:

    • ProductVersion: Returns the full product version.
    • ProductLevel: Returns the product level (e.g., RTM, SP1, CU).
    • Edition: Returns the SQL Server edition (e.g., Enterprise, Standard, Express).

    Here’s an example query:

    SELECT
    SERVERPROPERTY('ProductVersion') AS ProductVersion,
    SERVERPROPERTY('ProductLevel') AS ProductLevel,
    SERVERPROPERTY('Edition') AS Edition;

    Click the "Execute" button or press F5 to run the query.

  3. Review the Results: The results pane will display the values for each property you requested.

Example

The output might look something like this:

ProductVersion ProductLevel Edition
15.0.4280.1 CU22 Enterprise Edition

Pros and Cons

  • Pros:
    • Returns specific version components.
    • Easy to use and understand.
    • Can be used in scripts and applications.
  • Cons:
    • Requires knowledge of the available properties.

Option 3: Using SQLCMD

SQLCMD is a command-line utility that allows you to execute SQL Server queries from the command prompt. This method is useful when you need to check the version remotely or in environments where SSMS is not available.

Step-by-Step Guide

  1. Open Command Prompt: Open the command prompt on your machine. Ensure that the SQLCMD utility is installed and accessible in your system's PATH.

  2. Execute the Command: Use the sqlcmd command with the -S parameter to specify the server name and the -Q parameter to specify the query. Here’s an example command:

    sqlcmd -S your_server_name -Q "SELECT @@VERSION;"

    Replace your_server_name with the actual name of your SQL Server instance. If you're connecting to a local instance, you can use . or (local) as the server name.

  3. Review the Results: The command prompt will display the output of the query, including the SQL Server version information.

Example

The output might look something like this:

Microsoft SQL Server 2019 (RTM-CU22) - 15.0.4280.1 (X64)

  1. Locate the Error Log: The location of the error log depends on your SQL Server configuration. By default, it's located in the LOG directory under your SQL Server installation path. For example:

    C:\Program Files\Microsoft SQL Server\MSSQL15.MSSQLSERVER\MSSQL\Log

    You can also find the error log location using SSMS. Right-click on the server name in Object Explorer, select "Properties", and then click on the "Advanced" page. The "Error log file" property shows the full path to the error log.

  2. Open the Error Log: Use a text editor (e.g., Notepad, Notepad++) to open the current error log file (usually named ERRORLOG).

  3. Search for the Version Information: Search for a line that contains the SQL Server version number. The version information is typically logged when the SQL Server instance starts.

Example

An example line in the error log might look like this:

2024-07-24 10:00:00.00 Server Microsoft SQL Server 2019 (RTM-CU22) - 15.0.4280.1 (X64) Jul 16 2023 14:32:07 Copyright (C) 2019 Microsoft Corporation Enterprise Edition (64-bit) on Windows Server 2019 Standard 10.0 <X64> (Build 17763: )
