- by pinaldave
I have been asked this question number of times and my answer always have been – search online and you will find the answer. Every single time when someone has followed my answer – they have found accurate answer in first few clicks. However increasingly this question getting very popular so I have decided to answer this question here.
I usually prefer to create my own T-SQL script but in today’s case, I have taken the script from web. I have seen this script at so many places I do not know who is original creator so not sure who should get credit for the same.
Question: How to retrieve SQL Server Installation date?
Answer: Run following query and it will give you date of SQL Server Installation.
SELECT create_date
FROM sys.server_principals
WHERE sid = 0x010100000000000512000000
Question: I have installed SQL Server Evaluation version how do I know what is the expiry date for it?
Answer: SQL Server evaluation period is for 180 days. The expiration date is always 180 days from the initial installation. Following query will give an expiration date of evaluation version.
-- Evaluation Version Expire Date
SELECT create_date AS InstallationDate,
DATEADD(DD, 180, create_date) AS 'Expiry Date'
FROM sys.server_principals
WHERE sid = 0x010100000000000512000000
GO
I believe there is a way to do the same using registry but I have not explored it personally. Now as I said earlier there are many different blog posts on this subject. Let me list a few which I really enjoyed to read personally as they shared few more insights over this subject.
