A Fine Slice Of SQL Server
Steven Sanderson makes a list but doesn’t check it twice:
Lists are fundamental data structures in R programming that allow you to store multiple elements of different types in a single object. This comprehensive guide will walk you through everything you need to know about creating and working with lists in R.

Comments closedAyman El-Ghazali solves a problem:
A few months ago, an ISV customer approached with a request to have notebooks run across Microsoft Fabric Lakehouse environments dynamically. Initially the first request was to allow pipelines in Fabric to pass parameters for file paths to help with data ingestion. This would allow the customer to use the same notebook across Lakehouse environments for the customers that they are serving. After resolving this, the scope increased to include the notebook execution. The notebooks should be able to run across workspace environments and not have to be attached to a Lakehouse at the time of execution. The solution presented below allows for the customer to run notebooks across environments but also allows them to run SQL queries against existing Lakehouse tables; additionally it allows for access to tables created during the notebook execution run without the notebook being attached to the Lakehouse.

Comments closedIn this video, I show how to perform a variety of database backup operations via PowerShell, using the dbatools PowerShell module. I also show how easy it is to test a database backup using dbatools.
I finally have a video shorter than 10 minutes long. Don’t worry, the next one will blow right past that figure.
Comments closedJoe Celko covers four useful properties of database transactions:
ACID is a cute acronym for Atomicity, Consistency, Isolation, and Durability. This is a set of properties we want in transactions in a database. The original work was done by the late Jim Gray, but this acronym is due to Andreas Reuter and Theo Härder at IBM. These four properties as defined by Reuter and Härder are as follows:

Comments closedKevin Wilkie says you’ve got mail:
For the many other parameters you can use with sp_sendmail, please refer to the Microsoft Documentation found here.
After running this stored procedure, SQL Server queues the email to be sent. From there, you should check often to see if it was actually sent. (And yes, it can get stuck there forever.)
With, Snowflake, it’s actually fairly close to the same basic principle as SQL Server.

Comments closedSandeep Pawar spreads the news:
I wrote a blog last year on the usefulness of KQLMagic command in Fabric notebook and made a suggestion that it should be part of the default runtime. Well, guess what – it’s now in the Fabric Runtime 1.3. No installation necessary and authentication is handled automatically.
Read on to learn more about how you can use KQLMagic in a Microsoft Fabric notebook to read from an Eventhouse.
Comments closedPaul Turley has the beginnings of a new series:
It’s time for a refresher and reboot on this important topic. Much has changed in the Power BI world, the core design principles remain the same, practices and architecture patterns have evolved over the past few years. Power BI has grown up in the enterprise space and Microsoft Fabric now adds new options and capabilities. Back in 2020, I began writing a series of blog posts titled “Doing Power BI the Right Way” and it has become my mission to evolve and maintain a current collection of the most important best practice recommendations. This has been my passion and topic of several conference talks, user group sessions and a book currently in development for O’Reilly that will help you prepare for the PL-300 Power BI Analyst exam and then guide you apply enterprise best practices in your solutions.
I work with hundreds of consulting clients who go through the same cycles, having the same experiences, facing the same challenges, many making the same mistakes, and many learning some of the same lessons. The purpose of this series is to share those lessons with you.

Comments closedGilbert Quevauvilliers wants to know about storage utilization in Microsoft Fabric:
This blog post will show you how to understand what is consuming your Fabric Storage.
If you want to know how I got this data, please read my previous blog post View all your Storage consumed in Microsoft Fabric – Lakehouse Files, Tables and Warehouses – FourMoo
With this Semantic model below, I could also create alerts to notify based on certain thresholds. For example, if total storage in a single App workspace is more than 100GB send me an alert (This could be done using Power Automate). Or it could be on too many files being stored, or even looking at the Parquet file sizes and if they are too small they would then need to be optimised (for better performance).
