My 20-day Learning Roadmap

To journey through this learning curve, I designed a comprehensive learning plan, outlining what I would learn each day.

Days 1-5: Getting Acquainted with SQL Basics

These initial days involved diving into the fundamentals. The "SELECT" statement, "FROM" clause, "WHERE" clause, "DELETE" and "INSERT INTO", became my new terminologies as I learned to draw data from databases.

Days 6-10: Leveling up with Advanced Concepts

I then moved to more advanced concepts like nested queries and wildcard operators. I mastered the use of the "WITH" and "FETCH" clauses, "UPDATE" and "ALTER" Tables, and more to conveniently filter data.

Days 11-15: Gaining Confidence with Practice

In this phase, I started executing complex aggregate functions, using the "DISTINCT" clause, "COUNT", "SUM", "AVG", "MIN", "MAX" Functions, "ORDER BY" and "GROUP BY" statements, and much more.

Days 16-20: Handling Real-World Problems

The final stretch had me learning to use Joins, a critical SQL concept. I practiced using the concepts of "UNION", "INTERSECT", "Aliases", "INNER", "LEFT", "RIGHT" and "FULL" Joins and other advanced relational operations.

Challenges and Overcome Methods

Conclusion

While speed isn’t typically associated with mastering a programming language, the achievement only proves that with the right resources and dedication, it's possible. My one advice to anyone trying to learn SQL would be: don't rush! Practice consistently, and you'll find yourself proficient in no time. Overall, the experience was enriching, and the knowledge I gained throughout this 20-day journey will undoubtedly serve me well in my career.
