In this introductory video of a SQL learning series, the speaker outlines a hands‑on, low‑technology approach to mastering SQL. He advocates using a "whiteboard method"—working without an editor, autocomplete, or AI assistance—to force deep understanding. Before writing any code, he suggests verbally explaining the choice of constructs (e.g., CTE vs. subquery) and drafting the solution in plain‑English pseudocode. The learning loop consists of learning one concept, writing queries, deliberately breaking them, and then fixing them, mirroring the pressure of a technical interview whiteboard test. The video ends by promising a follow‑up that will list free advanced‑SQL resources and asks viewers which resource they will start with.

If I had to learn SQL from scratch today, I'd just do this. I'd use the whiteboard method. No SQL editor, no autocomplete, no AI to draft the code for me. Before I type a single line, I have to verbally explain why I'm using a CTE instead of a subquery. I would write the solution in pseudocode, plain English, to solve the logic before even touching the syntax. If you can pass a whiteboard test in a Word doc, a real technical interview will feel like running with a weighted vest taken off. Learn one concept, write the queries, break them, and then fix them. That is how I build the skill. This is part 1 of my SQL series. Next, I will show you the free resources that I would use for advanced SQL. Which one are you going to start with?
