  • Temporal Tables - Part 3 - Syncing Multiple Modifications

    Back last June, I started this series on temporal tables, and in my head, I had enough information to make an educated set of examples on how to use them. In the back of my mind though, I knew that I hadn't quite thought enough about the whole process, particularly when you have several rows (or as I will note in the next blog entry, tables) that ...

  • Row Level Security-Part 3-A few more advanced scenarios

    In this final entry (for now!) in my series on Row Level Security (Part 1, Part 2) I am going to show a couple of slightly more complex scenarios. I will only scratch the surface of what you could do, but keep in mind that performance is really important to how you make use of Row Level Security. In a future blog, I will build a couple of ...

  • Row Level Security–Part 2-Write Operations

    In the first entry in this series (to view, follow this link), I took a look at the how row level security worked with read operations. Now in this entry, I want to expand that to how you use it to limit what a user might write to, or delete from a table. To recap our current situation, we have three users: CREATE USER BigHat WITHOUT ...

  • How Sure Are You of Your PASS Summit Abstract?

    You know who you are. You have a presentation idea that has been percolating since last October. You have asked friends and coworkers if it is a good idea. You may have presented it at 10 SQL Saturdays to thunderous appreciation. You may have even tried to submit last year but was turned down.  You have this abstract written and may have even ...

  • Row Level Security – Part 1–Simple Read operations

    This is part 1 of my Row Level Security blogs for my upcoming book project. Row Level Security is a very interesting feature. Unlike Dynamic Data Masking (link), which looks interesting on it's face, once you dig in the utilization of the feature looks to be limited by how granular you can make the security work. Row Level Security on the other ...

  • Dynamic Data Masking - Part 2–Security and Incorporating into Code

    This is part 2 of my Dynamic Data Masking blogs for my upcoming book project. Part 1 is here: Dynamic Data Masking - Part 1 - The Mechanism. Previously, in my first blog on Dynamic Data Masking - Part 1 - The Mechanisms, we had created the following table (I include this so you can see the DDL of creating the table with the MASKED WITH clause on ...

  • Dynamic Data Masking - Part 1 - The Mechanism

    This is part 1 of my Dynamic Data Masking blogs for my upcoming book project. Part 2 is here. An interesting feature that is being added to SQL Server 2016 is Dynamic Data Masking. What it does is, allow you to show a user a column, but instead of showing them the actual data, it masks it from their view. Like if you have a table that has email ...

  • Is It Ever Better to Not Name Constraints?

    This is part 1 of my Tips and Tricks blogs for my upcoming book project. For all of my professional writing career, I have been forced to be on the top of my formatting game when writing code. Uppercasing this, spacing this, aligning that, formatting code just right. In my personal life, I also try to format my code in a readable manner, though ...

  • Dragged Kicking and Screaming into the Clouds

    When I first heard about the cloud I rolled my eyes. This will never take, it sounds very much like the mainframes we came to know and hate (my first database project was killing a mainframe that was costing our non-profit organization $15000 a month, which as a non-profit was simply horrible.) Even four years ago when I was writing "Pro SQL ...

  • Post PASS Summit Resolutions

    Many years I have tried early in the year to list a set of “New Year’s Resolutions” but one thing I have noted every year is it isn’t New Year’s Day that is the defining part of my year, but rather it is the PASS Summit that defines my year. Usually, by the time the end of October rolls around, I am pretty spent. The summer has ended, and all of ...
