A comprehensive journey through SQL problem-solving.
Introduction:
I've embarked on the LeetCode SQL50 challenge to enhance my SQL skills and explore a wide range of SQL concepts. This challenge covers topics like basic selects, joins, aggregate functions, sorting, grouping, advanced selects, subqueries, and string functions.
Key Learnings
So far, I've gained a solid understanding of basic SQL syntax, including SELECT, FROM, WHERE, GROUP BY, Operators and ORDER BY clauses.
Future Goals:
I plan to continue working through the SQL50 challenge and focus on more advanced topics like subqueries and string functions. I'm also interested in learning about performance optimization techniques.
Acknowledgements:
I would like to thank the LeetCode community for providing valuable resources and discussions.
