The Career Influence of Usenet Strangers (T-SQL Tuesday #096)

8
A freshly minted Computer Science graduate at the tail end of the dot-com era, I had three basic requirements for my first job: (1) money; (2) money; (3) more money. (I was going to be a millionaire, don't you know!) So I did pretty much the same thing as all of my friends: got...

Playing the Third-Party Recruiter Game (T-SQL Tuesday #093)

Finding a new job can be a long and stressful proposition. This holds true even for skilled candidates. And even for skilled candidates in an atmosphere like we have in 2017—in which everyone who is employable is, for the most part, employed, and IT positions often stay open for months due to a lack...

The SQL Hall of Shame

SQL Server is a big product, with lots of features. Many of the features—hopefully the vast majority of them—are solid and allow us to build trustworthy, secure, and reasonably usable database applications. But nearly everyone has stumbled into a few, shall we say, “darker areas” of the product now and again. Strange and seemingly...

The Guru (T-SQL Tuesday #089)

20
I became a consultant a bit earlier in my career than was probably wise. The going was rough at first, with periods of feast and periods of famine. Although I had several clients, I didn’t understand how to sell services or schedule my workload, and so I’d wind up either doing huge amounts of...

Solving the Net Changes Problem with Temporal Tables (T-SQL Tuesday #087)

SQL Server 2008 was perhaps not the meatiest of SQL Server releases, but it did have one especially promising feature: Data change detection. Or maybe two features, depending on how you look at things. I’m talking, of course, about the almost confusingly similarly named Change Data Capture and Change Tracking.Change Data Capture was the...

The SQL Genie (T-SQL Tuesday #086)

At some point a long time ago, when I was first getting serious about SQL Server, I became aware of an open secret.You see, there was this special Microsoft alias called “sqlwish.” Those in the know could send an e-mail and pass along suggestions for improving the product. And they wouldn’t just vanish into...

T-SQL Tuesday Rules of Engagement

Just over seven years ago (wow, does time fly!) I launched T-SQL Tuesday. The core idea is simple: Each month, one blogger acts as “host.” He or she is responsible for choosing an interesting topic in or related to the SQL Server realm. Then a bunch of other bloggers all write articles on that...

Temporal Tables: Connect Item Round Up

I think it's possibly the most compelling feature in the release, with broad applications across a number of different use cases. However, just like any v.1 feature, it's not without its faults.I created a couple of new Connect items and decided to see...
