Our courses on writing T-SQL queries for SQL Server, SQL for PostgreSQL, and SQL for Snowflake have all been very popular. But we’ve had so many requests for a similar course targeting MySQL, and we’ve delivered that now.

We’re pleased to announce that this course is now available, and it’s low cost. Just $95 USD. It’s easy to set up to do the practical work so you get real experience with MySQL. You can find details of the course here:

One of the best ways to grow a small business is to find something a large business needs, yet for some reason, they can’t or won’t do themselves.

This happens for many reasons:

Specialized Expertise

Small companies often have deep niche skills that the large company either doesn’t have or can’t easily build internally (e.g., a boutique AI consultancy, a specialist in SQL Server performance tuning).

These small firms might work across many clients, so they’re exposed to the latest best practices and pitfalls the big company hasn’t yet encountered. Large companies often also have marketing-driven outcomes rather than just technically-driven ones.

The SQL Server team has been working towards making databases more standalone, and less dependent on the server, for quite a while. SQL Server 2012 was the first version that had a concept of a contained database. The thinking was that you should be able to move databases around to different servers and, in that case, users would follow with the database because they didn’t have a dependency on logins, which was the case up until then.

This second article in a two-part series shows you how to control the execution context of stored procedures. This time, it’s by using digital signatures and code signing.

During a recent consulting engagement, I noticed that the client needed to control the security context a stored procedure was running under but was using a convoluted method to do so. Changing the security context that stored procedures run under is a common requirement, letting users execute code via stored procedures that they aren’t allowed to execute directly.

Lately, I’ve seen a number of people commenting that they think the Publish to Web options in Power BI aren’t secure. They are secure. You just need to use them appropriately.

The issue

When you publish to web with Power BI, all data in the semantic model that the user is allowed to see is visible, not just the data shown in the visual that’s on your report. There’s nothing to stop the user using DAX to get to it.

I have been using Bunny Stream for hosting videos lately. I love those people. What a great service.

But I wanted to add a few videos to our SQL Down Under website that was a Hugo Azure Static Website. I added the embed code from the Bunny Stream site for the video, and what I found was:

• The videos appeared and played on desktop versions of Chrome or Edge
• The page appeared but no videos appeared when viewing the page from either Safari or Chrome on iOS

At first, I thought it might be a screen resolution thing, but it didn’t work on either an iPhone, or on an iPad that had the same resolution as my laptop where things did work.

As soon as I started working with a recent version of SSMS, I realized that I didn’t like how heavy the grid lines were in the output:

I really wanted the data to be the focus, not the lines. They seemed much darker than on the previous versions. Note that this is a personal preference. I can imagine some people preferring them as they now are. Fortunately, though, you can now change the color of the lines. In Tools, Options, Fonts and Colors, in the Grid Output section, there is now an entry for Grid Results Lines.

This is part 1 of a two-part series that shows you how to use the EXECUTE AS clause to change and control security context for stored procedures. Up next month will be digital signatures.

During a recent consulting engagement, I noticed that the client needed to control the security context that a stored procedure was running under but was using a convoluted method to do so. Changing the security context that stored procedures run under is a common requirement, letting users execute code via stored procedures that they aren’t allowed to execute directly.

I posted a while back about being able to have random advertisements for our training courses in the sidebar for my blog. You’ll see one to the right of this post.

That has been working great, and every time I do a new build (each day), each page ends up with a random course advertisement.

Priorities

What I’ve now decided though, is that I didn’t want all the courses to show up with the same frequency. I wanted to assign a priority to each one, from 1 to 10.

One of the bigger changes in recent versions of SSMS has been the inclusion of connection encryption details on the main connection page:

Previously, this was on another page of the logon dialog. Once you make the connection though, there previously was no indication of what type of encryption was used. Now that appears in the query status bar as a lock. When you hover over the lock, it shows you the type of encryption that had been selected.
