Top 5 Mistakes to Avoid When Learning SQL โ๐
1๏ธโฃ Ignoring Data Basics
Don't skip understanding tables, rows, primary keys, and relationships. These are the foundation of SQL.
2๏ธโฃ Memorizing Queries Without Practice
Reading syntax isn't enough. Write real queries on sample databases to retain concepts.
3๏ธโฃ Not Using Joins Early On
Many avoid JOINs thinking they're hard. Practice INNER, LEFT, and RIGHT JOINs with real examples to understand table relationships.
4๏ธโฃ Skipping GROUP BY and Aggregates
GROUP BY with COUNT, SUM, AVG, etc., is core to analytics. Learn it early and use it often.
5๏ธโฃ Not Practicing Real-World Scenarios
Writing SELECT * from a table isn't enough. Use projects like sales reports, user activity tracking, or inventory queries.
