Distributed query for license key

Question

Hello,
I have a distributed query that I'm hoping is retrieving the license key information below:
USE master
GO
create table #version
version_desc varchar(2000)
insert #version
select @@version
if exists
select 1
from #version
where version_desc like '%2005%'
Begin
DECLARE @Registry_Value_2005 VARCHAR(1000)
EXEC xp_regread 'HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.1\Setup','ProductCode',@Registry_Value_2005 OUTPUT --2005
SELECT @@version as 'version',@Registry_Value_2005 as 'license_key'
End
else if exists
select 1
from #version
where version_desc like '%express%'
Begin
DECLARE @Registry_Value_2008_express VARCHAR(1000)
EXEC xp_regread 'HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\Setup','ProductCode',@Registry_Value_2008_express OUTPUT -- 2008 express
SELECT @@version as 'version',@Registry_Value_2008_express as 'license_key'
End
else if exists
select 1
from #version
where version_desc like '%R2%'
Begin
DECLARE @Registry_Value_2008_R2 VARCHAR(1000)
EXEC xp_regread 'HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\Setup','ProductCode',@Registry_Value_2008_R2 OUTPUT -- 2008 R2
SELECT @@version as 'version',@Registry_Value_2008_R2 as 'license_key'
End
else if exists
select 1
from #version
where version_desc like '%2008%'
Begin
DECLARE @Registry_Value_2008 VARCHAR(1000)
EXEC xp_regread 'HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10.MSSQLSERVER\Setup','ProductCode',@Registry_Value_2008 OUTPUT -- 2008
SELECT @@version as 'version',@Registry_Value_2008 as 'license_key'
End
else if exists
select 1
from #version
where version_desc like '%2012%'
Begin
DECLARE @Registry_Value_2012 VARCHAR(1000)
EXEC xp_regread 'HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.MSSQLSERVER\Setup','ProductCode',@Registry_Value_2012 OUTPUT -- 2012
SELECT @@version as 'version',@Registry_Value_2012 as 'license_key'
End
else
Begin
select 'version not recognized'
End
drop table #version
I'm noticing the 'key' is coming back the same across our 2012 instances and I'm pretty sure this isn't right. Am I retrieving the right value from the registry? I want to get the actual key that is installed when SQL is installed. Please help also feel
free to borrow this code if you like.
Thanks!

Hi phil,
The following query will return the serial number in binary format, you can convert this binary value to product key as other post. For more details, please review this similar
blog.
use master
GO
exec xp_regread 'HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Microsoft SQL Server\110\Tools\Setup','DigitalProductID'
GO
Regarding to the product code, SQL Server consists of different products registered in the Registry. Each product has a product code (a GUID) as well as an installation package code (also a GUID). For more details, please review this similar
thread.
Additionally, for license issues, please call
1-800-426-9400,
Monday through Friday, 6:00 A.M. to 6:00 P.M. (Pacific Time) to speak directly to a Microsoft licensing specialist. For international customers, please use the Guide to Worldwide Microsoft Licensing Sites to find contact information in your locations.
Thanks,
