This is working in EM:
EXEC Master..xp_regread 'HKEY_LOCAL_MACHINE', 'SOFTWARE\Microsoft\MSSQLServer\Setup', 'SQLPath'

How can I implement that in a stored procedure:
________________________________________
Declare @InstallPath varchar(100)
SET @InstallPath = Exec Master..xp_regread 'HKEY_LOCAL_MACHINE', 'SOFTWARE\Microsoft\MSSQLServer\Setup', 'SQLPath'
________________________________________

The above is throwing an error, and beside it return 2 column I only want the 'Data' col that have the path.

Help with syntax or workaround please !

Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

Yes Paul's method is best to get the scaler values.

SNilssonAuthor Commented:

Your method is working fine Imran, however Paul's returned NULL.
paeloCommented:
Size problem, sorry.

Change that to DECLARE @test (or @InstallPath) varchar(200) or something larger and it should be fine.
