ICYMI: Ten Query Techniques Every SQL Programmer Should Know (Video)

One of the benefits of joining PASS is that you get access to their expansive library of conference videos. (Membership is free. So join now. What'dya want, a hand-written invitation?!?)

DBTA – 6 Reasons to Think About Upgrading to SQL Server 2014

  If you’re an IT manager, the first thing I’d like to tell you is how invested Microsoft is in SQL Server. While earlier incarnations of executive leadership focused in other areas (anyone remember “Developers! Developers! Developers!”?), Microsoft’s new leadership is very bullish on SQL Server. And, why not? After Microsoft Office and Windows Server, SQL Server is Microsoft’s third biggest money-making product line. Check out the recording of the “Accelerate your insights” webcast, about SQL Server 2014, featuring appearances by CEO Satya Nadella, COO Kevin Turner and CVP Quentin … [Read more...]

SQL Injection – Why the Heck Does this Keep Happening?!

  I'm decidedly old-school in a few of my habits. My morning routine, barring anything out of the ordinary, is one such example. Typically, I'll get up between 6:30 to 7:00 am, grab my first cup of coffee, and then chat with my daughters for a few minutes before seeing them off to school. Next, I make a bowl of oatmeal (a great choice for diabetics like me), pour a second cup of coffee, and browse the local paper, The Tennessean, while I have breakfast. On the morning of August 5, I had the added pleasure of spewing said coffee and oatmeal all over my morning paper when I read the … [Read more...]

Listen to Lead

I've got a question for you. Where did you learn how to listen? Of all the coaching and consulting clients I have asked that question to, not one has had formal training to become a better listener. Some have pointed to the works of Stephen Covey and others like him who advocate, “seek first to understand and then to be understood.” But even those who know that often find it difficult to put the concept into practice. It seems that many people have the same view of listening that they were given in kindergarten: “sit still and be quiet." Read the rest of this article at … [Read more...]

DBTA – PowerBI: The Self-Service BI App That Can Change Your Life

Here’s a real-world story: Data collection and analysis is, ironically, for a data management profession, one of the toughest parts of my job. I regularly pull data from our various databases and packaged application reporting systems for CRM, licensing, and user information. If you’ve ever worked with a packaged product, such as a CRM system, that includes reporting and querying features, then you know how inflexible they are. It can be infuriatingly difficult to get data out of these systems, systems for which you paid big money, without losing sleep, hair, and peace of mind. Working with … [Read more...]

Preventing tl;dr Emails

  A new abbreviation is beginning to take hold. I first heard of it on Seth Godin’s blog. The abbreviation? tl; dr. Too long; didn't read. I like the new abbreviation. It gives voice to something that has been going on for many years. The elephant in the room now has a name. For years, writers of emails have tried to use the medium to provide a comprehensive thesis on a subject. They have drafted elaborate prose in an effort to sway or convince the recipient of their position. All the while, the recipients have, at best, simply skimmed over the email and set it aside. It was … [Read more...]
