I spend a lot of time working with teams of DBAs and developers who need to fix performance problems. One of the real issues that I see time and again though, is people fixing the symptom, not the problem.
Many DBAs spend their time tracing query activity, working out which queries the system is spending a lot of time on, and then working out how to make those important queries run faster.

I teach SQL Server, BI, Azure, and AI classes on a fairly regular basis, and one thing I love to do is to show attendees images (or photos) of where the application of the technology has gone very right or very wrong. Ever since I’d installed Windows 10 though, that became much harder.
The Photos app that’s installed with Windows 10 must have someone who loves it, but that’s not me. There seems to be no way to just have it automatically maximize the images, so I’m always showing them, then having to resize them.

In an earlier post, I mentioned how useful the F1 key is. On its own, it provides syntax help, but when you highlight an object and hit Alt-F1, you get to see metadata about the object.
Under the covers, this just runs the sp_help stored procedure. Alt-F1 has been mapped to that.
You can see where this is configured, change it if required, and/or configure other procedures as well.
In Tools, Options, Environment, Keyboard, then Query Shortcuts, you can see this:

When I’m working with a SQL Server database, I often need a simple list of all the indexes that are already in place. I want it in a concise form. In our free SDU Tools for developers and DBAs, we added a procedure ListIndexes to do just that, and to provide their details in a form that’s easy to consume programmatically if you need that.
You can see how to execute it in the main image above. The procedure takes these parameters:

One thing that I see time and again on customer sites is staff who really don’t know what they’re doing in trying to solve a problem, or when they are trying to implement a new solution, yet their company just continues to pay them to stumble around while getting almost nowhere.
I’m not talking about someone who’s taking longer to achieve something than an expert. I’m talking about staff who are really out of their depth.

I first started using SQL Server back in 1992 with version 4.2 I was running a software house and was hoping to use SQL Server as the back end of our updated application. 4.2 wasn’t up to it. Versions 6 and 6.5 were closer but I still thought they needed far too much administration for me to be comfortable deploying them to most customer sites. Version 7 though, changed the game. Rather than having to manage devices (which was painful), we now had just standard operating system files, and even had options for automatically growing and shrinking the files.

I’ve been spending a lot of time lately doing DevOps related work, and I thought it was important to post a review of what is often considered the first “DevOps fictional book”. I know that sounds like a geeky book but it’s not quite as you might expect. The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win by Gene Kim, Kevin Behr, George Spafford is a bunch of fun.

In an earlier post, I mentioned that you can create a registered list of servers, either in Local Server Groups or stored in a Central Management Server.
What I didn’t really talk about though, is what you can do with these groups of servers, rather than just executing queries on an individual server.
I’ve created three local server groups, for my development, UAT, and production servers.
The Development Servers group has three database servers in it. If I right-click the group, rather than any individual server, we get these options:

One of the challenges when you have foreign keys in place, is that there are restrictions on what you can do to tables that are the targets of the foreign keys. What’s often needed though is a list of all references to a particular table or set of tables.
In our free SDU Tools for developers and DBAs, we added a function ListIncomingForeignKeys to do just that, and to provide their details in a form that’s easy to consume programmatically if you need that.

I posted the other day about how the pricing of apps has become silly. Most apps are priced so low that there really isn’t much income but worse, most don’t have a business model for the authors.
I’m sure that many smartphone app developers just think they can offer an app and get a bunch of money in quickly. They don’t seem to have thought about what happens beyond that point.
