Sql-Server

I recently upgraded my laptop to Visual Studio 2026. The upgrade went quite smoothly except for one thing.

I received an error that told me that the RDLC Report Designer for use with SQL Server Reporting Services wasn’t going to work any more. In my case, we use that report viewer even without Reporting Services, by just uploading datasets in applications. I’ve found it very convenient. But I still needed the report designer so I could add new reports or change existing ones.

This is an update of a post that I wrote for SQL Server 2022 . Unfortunately, those instructions needed to be updated, not because anything notable has changed in SQL Server 2025, but because the recent distribution of Python has changed. Thanks to Peter Bishop for reporting what was now missing.

R and Python in SQL Server

One of my more surprisingly popular blog posts in the past talked about Machine Learning: Testing ycd our installation of R and Python in SQL Server 2017. The problem is that SQL Server 2022 changed things, and then there is a further issue with the Python distribution.

This is a post in the SQL Interview series. These aren’t trick or gotcha questions, they’re just questions designed to scope out a candidate’s knowledge around SQL Server and Azure SQL Database.

Section: Development Level: Intro

Question:

You issue the following query against the dbo.Customers table:

SELECT * FROM dbo.Customers;

The table has a clustered index on the CustomerID column.

When you have not specified an ORDER BY clause, which order will the rows be returned in?

Early versions of SSMS included the ability to work with source control systems. The way that worked was that SSMS implemented an SCCI (Source Code Control Interface). It would let you connect to any source control system that implemented that interface.

For a while, SSMS lost any ability to talk to source control. I thought that was a pity as I make extensive use of projects within SSMS and source control is where I want them stored.

One change that was applied to Azure SQL Database a while back, and is coming in SQL Server 2025, is the use of ANSI string concatenation operators.

SQL Server has been using the + sign as a string concatenation operator since the early days, but that’s the same operator that’s used for numbers, and it’s not the ANSI standard. You’ll find that other database engines like PostgreSQL do not use + to join strings together; they use the || operator. I’ve been writing quite a lot of PostgreSQL lately, and avoiding using + to concatenate strings is always a challenge for my coding muscle memory.

This is a post in the SQL Interview series. These aren’t trick or gotcha questions, they’re just questions designed to scope out a candidate’s knowledge around SQL Server and Azure SQL Database.

Section: Administration Level: Medium

Question:

A developer in your team has observed that your database servers are very I/O bound. He thinks the I/O is simply too slow.

What he’s suggesting is that you replace all use of temporary tables with table variables. His argument is that they are memory-based instead of disk-based and that this should help to reduce the I/O load. Your applications make heavy use of temporary tables, and most have large numbers of rows.

During a recent consulting engagement, I was asked about how to use column-based encryption in SQL Server. In this article, which is the second part of a two-part series, let’s explore how to get started using column-based encryption.

In the previous post , I provided background information about encryption and certificates.

If you’re not very familiar with these technologies, you should read that previous post before this one.

Encryption Technologies in SQL Server

Way back in SQL Server 2005, Microsoft introduced an amazing array of technologies. I suspect that many SQL Server professionals aren’t aware of just how many technologies were introduced in that release. It’s not surprising that professionals are still learning about a number of these technologies, even 20 years later. In particular, questions regarding certificates, keys, and column-based encryption still draw blank responses from most SQL Server professionals.

SSMS has the ability to work with different encodings when you are opening or saving files.

When you use File and Open, note that beside the Open button is a drop-down arrow:

The Open With option leads to this:

In that screen, you can choose an existing value or click Add to add another program that you want to use for opening files of that type:

As an example, you might want to use a different XML or JSON editor.

During a recent consulting engagement, I was asked about how to use column-based encryption in SQL Server. In this article which is the first of a two-part series, let’s explore the technologies involved and how to get started with using column-based encryption. Next time, we’ll continue with using these technologies for column-based encryption.

Encryption Terminology

Encryption is the science of hiding secrets. Information that needs to be protected (often called plaintext) is converted (or encrypted) to a form (often called ciphertext) that is difficult for another person to read within a reasonable period of time.

It was great to catch up with Simon Sabin today and to have him on another SQL Down Under podcast.

Simon is the founder of Sabin.io where he revolutionizes the data practices of his clients.

Simon has a track record spanning diverse sectors like finance, retail, insurance, and motor sports and is recognized as a data expert. I’ve known Simon for a long time. He was a Data Platform MVP from 2005 to 2024, and a fellow member of the Microsoft Regional Director program.
