Gethyn Ellis:My SQL Server You Tube Channel

Its been an interesting weekend at gethynellis.com I have been attempting to put together a SQL Server YouTube channel. I’m planning on put lots of tutorials and how to videos on there. David P already has his own, where he records his SQL Saturday talks. Mine will be a little more “bits size” with the videos and tutorials being broken down into small chunks. Hopefully under 10 minutes long per video.

I’m planning on show casing to you some of the awesome features I that SQL Server has to offer. Features that you can use to ensure that you mission critical database

· Perform well
· Your data is kept secure
· Can be recovered in the event of a disaster
· Are highly available – I’ll show you the high availability features that allow you to quickly failover to another site minimizing business disruption
Maybe a look at running SQL Server in the cloud too

You can see my attempt at an introduction below – believe it or not this short introduction which lasts just over a minute took an hour to write and construct and over 5 attempt or takes to film. Its harder than many make it appear no doubt the more I practice the better I’ll get at it.

The first two tutorials are in production, I have the content and slides and demos pretty much done – it just needs sewing together. Which is what takes the time. I hope you enjoy please do feel free to leave a comment if you have any suggestions on content, tutorials or anything else for that matter.

Update - Before I published this post I posted the video to youtube and posted a link out on twitter...@kevchant was kind enough to watch it and spotted some mistakes, which I have corrected. Thanks Kev

SQL Server 2012 and Virtual Service Accounts

This post is written by David Postlethwaite
If you are using SQL Server 2012 you will probably have noticed that the default account for the SQL services has changed from that used in previous versions. With SQL 2005 and 2008 the default account for SQL service and SQL Agent service was “NT Authority\System”. This is one the built in accounts on a Windows machine, managed by the machine and selectable from a dedicated dropdown list

The Network Service account was introduced in Windows 2003 as an alternative to using the LocalSystem account, which has full local system privileges on the local machine, a major security concern.
The Network Service has limited local privileges easing these security concerns but when many services on a machine use the Network Service account it becomes harder to track which service is actually accessing resources and performing actions, because all the services are using the one Network Service account.
Also, this account, by default, has sysadmin per…

Always Encrypted

By David Postlethwaite

Always Encrypted is new features in SQL Server 2016 and it is also available in Azure SQL Database. Here you can encrypt columns in a table with a master key and a certificate so that they will appear as encrypted strings to those who don’t have the required certificate installed on their pc.
Once the certificate is installed on the computer then the unencrypted data can then be seen as normal.

The data passes from database to your application as the encrypted value, only the application with the correct certificate can unencrypt the data so it is secure across the wire. This will go some way to resolving the concern of people worried about putting their sensitive data on a shared server in the cloud such as Microsoft Azure and accessing the data across the Internet.

At the time of writing Always Encrypted is only supported with ADO.NET 4.6, JDBC 6.0 and ODBC 13.1 but expect other driver to become available.

The calling application (including SSMS) must also hav…

How to Setup Kerberos Correctly

David was in Copenhagen this weekend delivering his Kerberos talk Taming the Beast: Kerberos for the SQL DBA to SQL Saturday Denmark. I have had a quick chat with him via email since he got back and he said he had a great time. The event was very well attended with 280+ attendees and his talk was well attended.

I think David is planning submitting a few sessions to SQL Saturday events in Europe in the next few months so look out for him there and we'll keep you posted as to his whereabouts when schedules get finalised later in the year.

David has pre-recorded his Kerberos talk. You can watch on you tube and I have also embedded it in this post if you want to see what his kerberos talk covers...
