An Introduction to Streamlit

Published 2024-07-10 by Kevin Feasel

I have started a new video series:

In this video, I talk about Streamlit, a great Python library for building data applications quickly. We discuss what data applications are, get an idea of how Streamlit compares to other code-first data visualization techniques, and start building a demo application. I also toss in a lengthy sidebar on Python virtual environments because of how important they are.

Streamlit certainly has its foibles—many of which I’ll cover in the series—but I like it a lot as a simple way of building data applications.

Extracting Strings before a Space using R

Published 2024-07-10 by Kevin Feasel

Steven Sanderson grabs a name:

Hello, R users! Today, we’ll dive into a common text manipulation task: extracting strings before a space. This is a handy trick for dealing with names, addresses, or any text data where you need to isolate the first part of a string.

We’ll explore three approaches: using base R, stringr, and stringi. Each method offers its unique advantages, so you can choose the one that fits your style best.

Click through for the three examples. I will note that if you’re actually using this code to split names, well, names tend to be a lot trickier than we give them credit for. Keep in mind that people can have multi-part names (“Debbie Mae” or “van den Berg”), so unless you know the data all follows a specific pattern, don’t assume the data follows a specific pattern.

Access Controls in PostgreSQL

Published 2024-07-10 by Kevin Feasel

Umair Shahid talks about access rights:

Access control is a fundamental aspect of database security, ensuring that only authorized users can perform specific actions on the data. Effective access control helps protect sensitive information from unauthorized access and prevents data breaches, which can have severe legal and financial repercussions for organizations.

PostgreSQL has a strong reputation for reliability, feature robustness, and performance. One of its notable strengths is its comprehensive support for various access control mechanisms, which allow database administrators to finely tune who can access what data and how.

It turns out that there’s a lot of overlap in how these work between SQL Server and Postgres, though the exact syntax may be a bit different for certain items.

Microsoft Healthcare Accelerator for Fabric

Published 2024-07-10 by Kevin Feasel

Tino Zishiri takes us through an accelerator solution:

Microsoft released the Healthcare Data Solutions in Microsoft Fabric in Q1 2024. It was introduced as a “A game-changer for healthcare data analysis” by Umesh Rustogi, General Manager of Microsoft Health and Life Sciences Data Platform.

Microsoft Fabric is a unified platform that bundles services, apps, and connectors under a single umbrella, providing users with the tooling to meet all data and analytics needs.

The Healthcare Data Solutions are built on top of this robust service offering. The solution is aimed at users who are looking for a powerful tool to integrate and transform Healthcare data. In addition, users can run real-time analytics, data science workloads and meet business intelligence needs without compromising the privacy and security of their data.

Automate the Power BI Incremental Refresh Policy via Semantic Link Labs

Published 2024-07-10 by Kevin Feasel

Gilbert Quevauvilliers needs to get rid of some data fast:

The scenario here is that quite often there is a requirement to only keep data from a specific start date, or where it should be keeping data for the last N number of years (which is the first day in January).

Currently in Power BI using the default Incremental refresh settings this is not possible. Typically, you must keep more data than is required.

It is best illustrated by using a working example.

Check out that scenario and how you can use the Semantic Link Labs Python library to resolve it.

Deployment and Release Strategies for Fabric CI/CD

Published 2024-07-10 by Kevin Feasel

Marc Lelijveld digs into CI/CD topics:

Recently, I wrote a blog about the new branch-out feature in Git connected Fabric and Power BI workspaces. In this blog, I will continue the topic of Git integration by discussing various setups you could consider in your Git integration, deployment and release strategies as part of your continuous integration and continuous delivery setup.

Will you connect Git only to your development workspace, or to all stages? And how do you handle your deployment? Keep reading to find out the different patterns you can consider!

Hey, I’m the one who’s supposed to tell people to read on to learn more!

Marc does a great job of laying out three patterns, so I’ll just complain a bit instead. The fact that this has been out for a year and still doesn’t support GitHub is annoying. I know that it’s scheduled to come out in Q3 of 2024, so it’s hopefully just a few months away. But it’s still annoying.

Unicode Characters in SQL Queries

Published 2024-07-10 by Kevin Feasel

Chad Baldwin does some interesting things with Unicode characters:

I don’t want to get too far into the weeds explaining encodings, code points, etc. Mostly because you can just Google it, but also because it’s very confusing. Despite all the hours I’ve spent trying to learn about it, I still don’t get a lot of it. There’s also a lot of nuance regarding encodings when it comes to SQL Server, different collations, and different SQL versions. However, I did come across this blog post that seems to break it down well.

Click through for a few scenarios, including things like tracking progress or marking data in a manner that’s easier to see then “True” and “False” values in columns.

Erin Stellato reaches out:

Hey SQL Tools fans!  We’re halfway through 2024 and due to a confluence of events we have a release of SQL Server Management Studio to announce, version SSMS 20.2.

While we’ve been focused on work for SSMS 21, we made time for a few updates to address known issues that affected your workflows and use of SSMS.  You can read about each update and fix in the release notes, but let’s cover some important fixes here.

Read on to see what’s new in 20.2, as well as some of the major plans in mind for SSMS 21.
