Most people make SQL harder than it needs to be.
They jump into advanced concepts like Window Functions, CTEs, and Query Optimization before mastering the fundamentals.
The result?
Lots of tutorials watched.
Very little SQL actually learned.
If you're serious about learning SQL, follow this roadmap:
✅ SQL Basics
✅ Retrieving Data
✅ Aggregate Functions
✅ Joins
✅ Subqueries
✅ Set Operations
✅ Data Manipulation (INSERT, UPDATE, DELETE)
✅ Database Objects (Views, Indexes)
✅ Advanced SQL (CTEs, Window Functions)
✅ Data Modeling
✅ Performance Tuning
✅ Security
And instead of spending months searching for resources, use these platforms:
📚 w3schools.com – Best for beginners
📚 SQLBolt – Interactive learning
📚 SQLZoo – Hands-on SQL exercises
📚 HackerRank SQL – Practice and assessments
📚 LeetCode SQL – Interview preparation
📚 DataLemur 🐵 (Ace the SQL & Data Interview) – Data Analyst & Data Scientist SQL questions
📚 Mode SQL Tutorial – Analytics-focused SQL
My recommended learning path:
W3Schools → SQLBolt → SQLZoo → HackerRank → LeetCode → DataLemur
The secret isn't finding another course.
The secret is writing SQL queries every day.
30 minutes daily for 90 days will teach you more than 100 hours of passive video watching.
Save this roadmap for later.
