A Fine Slice Of SQL Server
In this video, I cover some news from Microsoft around the deprecation of the Azure Machine Learning SDK v1. We’ll take a look at the upgrade guide and see what it will take to perform this upgrade.
Microsoft will still support the SDK v1 until September of 2026, so we have a year to get code sorted out. The CLI v1, however, will go away sooner, so be sure you’re keeping up on that.

This is one of those blog posts you write so that 2 years later, you can look it up to remind yourself how to do something.
I found myself needing to figure out if “today” was the end of the month in PowerShell. In T-SQL, this is easy, as we have the
EOMONTH()function. But PowerShell (the .NETSystem.DateTimestruct) doesn’t have the same thing.
Read on for the solution Andy came up with.

I come from a TSQL background, so using SQL makes it easy for me to work with data.
There are multiple ways to use SQL in a PySpark notebook, and when I started using a Python notebook it was not so straightforward.
In this blog post I will show you how I use SQL Code.
As mentioned previously I am by no means an expert, I typically find a way that works, is fast and doesn’t consume a lot of capacity. If that works consistently for me then that is how I go about it.
Click through for the solution, which uses DuckDB. As such, the SQL syntax isn’t T-SQL—it’s more like psql. But it does do a great job of interacting with Parquet files and Delta tables.
Leave a CommentMircea Dragan doesn’t want to type everything out:
I have a database backup that I need to restore on another instance of SQL Server. Is there way to generate the SQL restore command by reading data from the backup file?
Read on to see how you can generate the database restoration command for a single database file dynamically.
Leave a CommentShayon Mukherjee runs into an interesting issue:
I recently discovered an unexpected behavior in PostgreSQL involving a pattern of using a Common Table Expression (CTE) with
DELETE ... RETURNINGandLIMITto process a batch of items from a queue-like table. What seemed straightforward turned out to have a surprising interaction with the query planner.

Database snapshots are one of those features that’s been around forever, but still solves real-world problems with very little setup. In a single statement you can capture a point-in-time, read-only copy of any user database, use it for reporting or off-load testing, and—if disaster strikes—revert the source back to that snapshot in minutes. This guide explains how snapshots work under the hood, walks through day-to-day tasks (including creating the original database), and highlights the pitfalls you should plan for before using them in production.
One additional tip that I’d offer: limit yourself to one database snapshot per database. There’s a performance cliff you can hit when you get fancy and try to have multiple database snapshots going at the same time off of the same database.
