Aggregation: A Special Course Offer

Hey everyone!

I’m thrilled to share something special. For those looking to truly master SQL Server’s aggregation and window functions, I’ve stumbled upon an amazing course that’s being offered at an insane discount.

Right now, the course is available for just $3 (yes, you read that right!) until November 15th. The course covers everything from the basics of data aggregation, handling null values, to advanced windowing techniques with the `OVER` clause. If you’ve ever been confused about how `GROUP BY` functions in standard queries or how partitioning works with windowing functions, this course is for you.

Grab this deal with the coupon code: AGG3.
Here’s the direct link https://stedman.us/AGG3 to the course with the coupon already applied. But hurry, the offer expires on November 15!

For context, this course is part of the “Querying SQL Server series,” and it fits perfectly in the “SQL Short” series collection. I’m genuinely excited for all the aspiring data nerds like myself to benefit from it.

Happy querying and I hope this course propels your SQL skills just like it has for others.

Until next time, Steve Stedman
