Key SQL Server Instance Information Extracted Using the SERVERPROPERTY Function

The SQL query you've provided retrieves various properties related to the SQL Server instance using the SERVERPROPERTY function. Here's a breakdown of each property:

1. SERVERPROPERTY('ProductVersion') AS Version:

   • This returns the version number of the SQL Server instance (e.g., 15.0.2000.5 for SQL Server 2019). It indicates the specific release version.

2. SERVERPROPERTY('ProductLevel') AS ProductLevel:

   • This property returns the level of the product installed on SQL Server, such as:
     • RTM (Release to Manufacturing)
     • SP1, SP2, etc. (Service Pack versions)
     • CU (Cumulative Update)
     • It tells you whether your SQL Server is using a base version or has been updated to a service pack or cumulative update.

3. SERVERPROPERTY('Edition') AS Edition:

   • This indicates the edition of SQL Server installed, such as:
     • Express (a free, limited version of SQL Server)
     • Standard
     • Enterprise
     • Web
     • Developer
   • It helps in identifying the SQL Server edition that is running (which determines features and licensing).

4. SERVERPROPERTY('EngineEdition') AS EngineEdition:

   • This returns a numeric code representing the engine edition of SQL Server:
     • 1 = SQL Server (standalone)
     • 2 = SQL Azure (Cloud-based SQL)
     • 3 = SQL Server Express
     • 4 = SQL Server Web Edition
     • 5 = SQL Server Standard Edition
     • 6 = SQL Server Enterprise Edition
   • This is useful to know the underlying engine type.

5. SERVERPROPERTY('MachineName') AS MachineName:

   • This property returns the name of the machine (computer) where SQL Server is running. It is the same as the hostname of the server.

6. SERVERPROPERTY('IsClustered') AS IsClustered:

   • This returns a value indicating whether SQL Server is running in a clustered environment:
     • 0 = Not clustered
     • 1 = Clustered
   • This tells you if SQL Server is part of a high-availability cluster (typically used for fault tolerance).

Example of Output:

The result of this query would look something like this:

Version	ProductLevel	Edition	EngineEdition	MachineName	IsClustered
15.0.2000.5	SP1	Enterprise	6	MyServer	0

• Version: The SQL Server version.
• ProductLevel: The service pack or update level.
• Edition: The SQL Server edition (e.g., Enterprise).
• EngineEdition: The engine type (e.g., standalone SQL Server).
• MachineName: The machine hosting the SQL Server instance.
• IsClustered: Whether the SQL Server is clustered (0 = No).

This information can be useful for administrators to assess the configuration, version, and environment of the SQL Server instance.
