I Taught SQL to Complete Beginners: Here's What Actually Happened
The author taught SQL to complete beginners with no prior coding experience, using relatable analogies and real-world datasets to explain core concepts. The course progressed from basic queries to advanced topics like JOINs, window functions, and CTEs, with students gradually gaining confidence and insight. Teaching SQL proved to be a rewarding experience as students transitioned from confusion to mastering analytical thinking with data.
- ▪The students came from non-technical backgrounds such as accounting and operations, with some relying on Excel for data management.
- ▪Key SQL concepts taught included SELECT, WHERE, HAVING, JOINs, window functions like RANK and LAG, and the use of CTEs for readable queries.
- ▪Real-world datasets like a fictional school and hospital were used to make learning relatable and practical.
