ESU registration script examples

Microsoft shares example scripts in T-SQL and Powershell that can generate the required SQL Server instance registration information. The Powershell samples create a CSV file that can be used to bulk register SQL Server instances covered by an ESU subscription.

T-SQL

To collect registration information from a single instance, you can use the example T-SQL script EOS_DataGenerator_SingleInstance.sql below:

DECLARE @SystemManufacturer NVARCHAR(128), @Edition NVARCHAR(20), @HostType NVARCHAR(30), @Cores int, @SQLVersion NVARCHAR(50)
DECLARE @machineinfo TABLE ([Value] NVARCHAR(256), [Data] NVARCHAR(256))

INSERT INTO @machineinfo
EXEC xp_instance_regread 'HKEY_LOCAL_MACHINE','HARDWARE\DESCRIPTION\System\BIOS','SystemManufacturer';
SELECT @SystemManufacturer = [Data] FROM @machineinfo WHERE [Value] = 'SystemManufacturer';
SET @HostType = 'Physical Server'
IF LOWER(@SystemManufacturer) = 'microsoft' OR LOWER(@SystemManufacturer) = 'vmware'
SET @HostType = 'Virtual Machine'

SELECT @Cores = hyperthread_ratio FROM sys.dm_os_sys_info;
SELECT @Edition = CONVERT(NVARCHAR(20), SERVERPROPERTY('Edition'))
SELECT @SQLVersion = CONVERT(NVARCHAR(50), SERVERPROPERTY('ProductVersion'))

SELECT SERVERPROPERTY('ServerName') AS [name],
	CASE LEFT(@SQLVersion,4) WHEN '10.0' THEN '2008'
		WHEN '10.5' THEN '2008R2'
		WHEN '11.0' THEN '2012'
		WHEN '12.0' THEN '2014'
		WHEN '13.0' THEN '2016'
		WHEN '14.0' THEN '2017'
		WHEN '15.0' THEN '2019'
		ELSE 'Other'
		END AS [version],
	LEFT(@Edition,CHARINDEX(' ', @Edition,0)-1) AS edition,
	@Cores AS cores,
	@HostType AS hostType;

Note: Verify if the Host Type is correct for your SQL Server instance.

Powershell

To collect registration information from all instances in a single machine, you can use the example Powershell script EOS_DataGenerator_LocalDiscovery.ps1. Can be used in an Azure VM, on-premises physical server or on-premises VM.

Note: Verify if the Host Type is correct for your SQL Server instance before uploading the CSV file.

To collect registration information from all instances listed in a text file, you can use the example Powershell script EOS_DataGenerator_InputList.ps1. Refer to ServerInstances.txt for an input text file example.

Note: Verify if the Host Type is correct for your SQL Server instance before uploading the CSV file.
