ServerName Property

The ServerName property of the SERVERPROPERTY function and @@SERVERNAME return similar information. The ServerName property provides the Windows server and instance name that together make up the unique server instance. @@SERVERNAME provides the currently configured local server name.

The ServerName property and @@SERVERNAME return the same information if the default server name at the time of installation has not been changed. The local server name can be configured by executing the following:

EXEC sp_dropserver 'current_server_name';
GO
EXEC sp_addserver 'new_server_name', 'local';
GO

If the local server name has been changed from the default server name at installation time, @@SERVERNAME returns the new name.

Version Properties

The SERVERPROPERTY function returns individual properties that relate to the version information whereas the @@VERSION function combines the output into one string. If your application requires individual property strings, you can use the SERVERPROPERTY function to return them instead of parsing the @@VERSION results.

Examples

The following example uses the SERVERPROPERTY function in a SELECT statement to return information about the current server. This scenario is useful when there are multiple instances of SQL Server installed on a Windows server, and the client must open another connection to the same instance used by the current connection.

SELECT CONVERT(sysname, SERVERPROPERTY('servername'));
GO

The following example uses the SERVERPROPERTY function in a SELECT statement to return version information about the product.

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