✅ Yes! You just got the Query Plan Decoded. Now you'll know how to read the execution plan.
But knowing what's slow isn't the same as knowing how to make it fast.
That's what Write Faster SQL is for.

One more thing before you go...

Learn to turn minutes-long queries into millisecond results... without being a DBA

What's Inside:

Module 1: Find the queries that are slowing you down

Run pre-built scripts to surface slow queries on your database (Oracle, SQL Server, MySQL, and Postgres) so you know exactly where to focus.

 

Module 2: Read an execution plan without getting lost

The execution plan goes from a mysterious black box to something you can actually read, and use to identify exactly what's slow and why.

 

Module 3: Add the right indexes to dramatically cut query time

Learn when indexes help, when they don't, and exactly which ones to create, including covering indexes that can transform performance on certain query types.

 

Module 4: Rewrite queries using strategies you should almost always use

Learn how to remove what's unnecessary, avoid common performance killers like DISTINCT, and compare before/after results so you know you haven't broken anything.

 

Module 5: Apply the strategies that make a real difference when they apply

CTEs, joins vs subqueries, CASE instead of UNION: learn when and why these rewrites improve both readability and performance.

 

Module 6: Use the advanced techniques worth knowing about

Pagination performance, function calls that avoid subqueries, choosing the right data types: the less-obvious strategies that can make a significant difference.

"A good investment"

"Your Write Faster SQL course is a good investment. The approach is interesting in that you are showing the same lessons against 4 different database engines. That helps developers understand the bigger picture rather than just ‘how to’ for their most common/only database"

- Doug T, course student

"Reduced our cloud costs"

"After the Database Star training, I did identify all the worst running queries on my production databases and fixed them and that reduced our cloud costs."

- David B, course student

"Best training material on SQL anywhere"

"It’s the best training material on SQL anywhere. You have a rare gift for making the complex simple. Thank you for all you do!"

- Brad C, course student

What This Is Not

This isn't a beginner SQL course. It picks up where the basics end.

It's not a DBA-level deep-dive either.

It's the practical system a working data analyst or developer needs to understand why queries are slow and fix them, taught clearly, without wasted time.

Average lesson length is 5–10 minutes. You can work through a module during a lunch break.
