Here’s a simple example on how to encrypt (and decrypt) values in SQL Server:
--How to Encrypt and Decrypt Text in SQL Server (2008+)
--Example by Clint Huijbers
@Key1 NVARCHAR(50) = N'8g87g8ag4r8hinsg^%$#F&^F&^F^F&ÛIBOUG(%*^R&$%&#%^C5'
,@Key2 NVARCHAR(50) = N'&*^%R%^**F$F*OUYBYUB*F%74d654d7f685f65f56f6v6vc88d'
,@ValueToEncrypt VARCHAR(150) = 'This is the value that will be encrypted by the built-in function of SQL Server with two keys and 128-bits encryption :) blablablablablablablablablabl'
,@EncryptedValue VARBINARY(350) --Increase the VARBINARY size when you increase the lengh of @ValueToEncrypt!
SELECT @EncryptedValue = ENCRYPTBYPASSPHRASE((@Key1+N'||'+@Key2),@ValueToEncrypt)
As of the 31st of March, SQL Server 2014 Developer Edition is now a free download:
Quote from MSDN:
SQL Server 2014 Developer Edition is now a free download for Visual Studio Dev Essentials members (you will be prompted to sign in to Visual Studio Dev Essentials before you can download SQL Server 2014 Developer Edition). We are making this change so that all developers can leverage the capabilities that SQL Server 2014 has to offer for their data solution, and this is another step in making SQL Server more accessible. SQL Server Developer Edition is for development and testing only, and not for production environments or for use with production data.
Visual Studio Dev Essentials is Microsoft’s most comprehensive free developer program ever, with everything you need to build and deploy your app on any platform, including state-of-the-art tools, the power of the cloud, training, and support.
Ohh….and this is also a nice one:
SQL Server 2016 Developer Edition, when released later this year, will also be free.

Did you know that by pausing the SQL Server service before restarting the instance we allow end users to continue their work uninterrupted and we also stop any new connections to the instance? This is a nicer way of telling people to “get out” of the database in order for the server to be rebooted. I wouldn’t leave the server paused for 60 minutes of course, but I would rather use this method than forcibly disconnect users and rollback their transactions.
When a server is paused you will see messages similar to this in the SQL Server error log:
Error: 17142, Severity: 14, State: 0.
SQL Server service has been paused. No new connections will be allowed. To resume the
service, use SQL Computer Manager or the Services application in Control Panel.
Error: 18456, Severity: 14, State: 13.
Login failed for user ''. Reason: SQL Server service is paused.
No new connections can be accepted at this time. [CLIENT: ]
Next time you are worried about rebooting during the day think about the pause button instead. It might be a nice compromise for your end-users.

The SQL Server Management Data Warehouse (MDW) is one of the most underappreciated features of SQL Server. But it’s a really handy feature which logs WaitStats and more, with almost no overhead (< 1% CPU). And…it does generate some nice reports which you could use to monitor your server (out of the box):
