The Bit Bucket

Leigh Sales is a well-respected local journalist. I feel some affinity for her, as she’s grown up in Queensland and often comments on things from her childhood that I clearly remember, even though Leigh is younger than me. I was fascinated to read her book Any Ordinary Day: Blindsides, Resilience and What Happens After the Worst Day of Your Life.

I decided to read her book before I knew anything about it at all. I knew it was “Any Ordinary Day”. I hadn’t realized it was “Blindsides, Resilience and What Happens After the Worst Day of Your Life”, so it was quite an unexpected story for me.

I remember being pleased some years back when I finished reading all of SQL Server’s Books Online (now just the documentation pages for T-SQL and SQL Server). The more of those pages I read, the more I was fascinated by small things that I hadn’t noticed even though I’d used the product for a long time. There’s so much to SQL Server and even just to T-SQL, that I still find unexpected things all the time.

In our free SDU Tools for developers and DBAs, a number of the string formatting functions have been quite popular, and we keep getting requests for even more.

Today’s post highlights another two of these. TrainCase is words with the first letters capitalized, then separated by underscores. KebabCase has dashes as separators. It’s named because it looks like a kebab.

You can see them (and some others) in action in the main image above, and in this video:

A quick piece today to talk about something that still seems to drive me crazy.

Why oh why do so many applications still default to putting a shortcut on the desktop when you’re installing them? And this applies to even very current applications.

I installed Chrome on some machines yesterday, and again, no question during install, but desktop shortcuts created.

Haven’t we moved on past this?

Nowadays, there really isn’t a need to plaster shortcuts all over the desktop for all the applications on the machine. And it’s counterproductive anyway.

I mentioned previously that databases hold collections of information about related things. But what are these “things”? Well, that’s what the tables are.

Tables are the most basic objects that live in a database. They hold information about one type of thing. You might call the things “entities” but it’s not 100% accurate. It’s the same problem if you call them “objects”. They aren’t really objects. They basically are just “things” that we’re storing information about, like employees, books, cinemas, products, and more. ANSI SQL called them “relations”.

I recently read The Hard Thing About Hard Things: Building a Business When There Are No Easy Answers by Ben Horowitz. I was interested to read it because Ben is a well-known and experienced entrepreneur, based in the Silicon Valley area south of San Francisco. He offers advice on how to really run startups.

I loved the way that Horowitz addressed failure. Instead of taking the business school approach of telling you how things should be done, and assuming that you’ll do everything correctly, he spends time telling you what to do after you’ve already screwed up.

This one is a very simple and quick tip.

When working in SQL Server Management Studio (SSMS), I often need to open File Explorer in the folder where the script file is stored. Turns out there is an easy way to do that.

There are two interesting options when you right-click the tab at the top of a query window:

Note that you can open the containing folder for the script. You can also copy the path to the script into the clipboard.

In our free SDU Tools for developers and DBAs, a number of the string formatting functions have been quite popular, and we keep getting requests for even more.

Today’s post highlights two of these. Screaming Snake Case is words in capitals separated by underscores. Sponge Bob Snake Case has underscore separated words (hence the “snake case” part) with alternating capitals. (It’s just for fun).

You can see them (and some others) in action in the main image above, and in this video:

When you create or rebuild an index in SQL Server, you can specify a FILLFACTOR value. It determines how full (as a percentage) that SQL Server should try to make the pages.

There is also one special value. Zero says “I haven’t set a value” and it applies the default, which by default, is 100%. Any value from 1 to 100 is the target percentage.

So why do people set lower values for FILLFACTOR? The argument is they know that their inserts are going to happen all over the table (i.e. not just neatly at the end of the table), and they’re trying to avoid page splits. And yes, lots of page splits can be a nasty thing. The most common problem case that people describe is where they’ve used a GUID as a clustering key (usually also a primary key) for a table. Then the inserts happen randomly throughout the table.

One concept that often confuses newcomers to SQL Server is the difference between a login and a user.

In an earlier post, I mentioned that being authenticated to a server is what’s called a login. In this example shown, I have a log in here called Malathi. But as I said, this means nothing about what databases Malathi then has access to.

The connection between a login and a database is what the concept of a user is about.
