A Fine Slice Of SQL Server
Holger von Jouanne-Diedrich takes us through Euler’s equation:
In this post, we will first give some intuition for and then demonstrate what is often called the most beautiful formula in mathematics, Euler’s identity, in R – first numerically with base R and then also symbolically, so read on!
Do check it out, even if the term “Euler’s equation” means nothing to you.
Comments closedTomaz Kastrun has fun with colors:
How about some colours in line graph?
Or even more wacky? Nevertheless, let’s create a function that generates some sample “mocked” data and draws a line chart:
The outputs look a lot like waveforms of spoken language, so you’ve got that going for you.
Comments closedChris Shaw lays out some of the problems with monitoring systems today:
A next-generation monitoring tool should not just provide the same standard old dashboard dressed up with new fancy graphs; it should empower me to be actionable. It needs to help me improve the environment and show me the impacts of those actions on the system, and thus, the business.
What the industry needs (for risk of rendering the title of this article bunk) is not another monitoring tool. I have tools that help me monitor and they do a fine job of specifically doing that. I need a tool that will take me into the future, I need a tool that makes me better and faster at what I do. This industry needs a smarter tool.
Click through to see what Chris has in mind, though the reason you haven’t seen some of this stuff is that it’s a couple orders of magnitude more difficult than what we do see in monitoring solutions. H/T Amanda White.
Comments closedDebbi Lyons and Vijay Kumar have a reminder for us:
While new innovations keep lighting up in the latest releases of SQL Server and Windows Server, support for older versions along with security updates will eventually end. This can lead to the potential for compliance gaps for workloads that still rely on these versions and create missed opportunities to apply innovation to business-critical workloads. SQL Server 2012 and Windows Server 2012, and 2012 R2 End of Extended support is approaching:
– SQL Server 2012 Extended Support will end on July 12, 2022.
– Windows Server 2012 and 2012 R2 Extended Support will end on October 10, 2023.
The news this week has mostly been about SQL Server 2016 ending mainstream support, but this is a bigger one. Fortunately, there’s still a year to procrastinate plan.
Kenneth Fisher pads some work:
I’ve been working on converting a piece of DB2 code into T-SQL and one of the functions I had to replace was lpad. It’s a simple enough function that will pad a string on the left with another string. So changing 1234 to 00001234. It’s a common enough task when formatting strings. And both DB2 and Oracle provide both lpad and rpad functions. However, guess what? SQL Server doesn’t. So how do we handle that in T-SQL? It’s a pretty easy pattern.

Comments closedPaul Turley answers a question:
This question comes up every few years in SQL Server Reporting Services. Of course, in Power BI Paginated Reports, we have the same features. A couple of days ago, Karthik posted this question as a comment to my post titled Chapter 7 – Advanced Report Design:
I am working on a SSRS report where the grouping is done to group the records in to multiple tabs/worksheets. When the report is exported to excel, the worksheets has the default name (Sheet1, Sheet2, Sheet3,…). Here I want to override the default worksheet name with (Tab1, Tab2, Tab3, …). The number of tabs/worksheets varies each time depending on the parameter selection by the user. How to address this? any suggestions please.

If I had a nickel for every time I’ve encountered “Cannot load script for execution,” I’d have a lot of nickels.
Save your nickels and read Andy’s post.
