This repository is a personal collection of SQL solutions answering business questions or random question i have written while practicing on StrataScratch and HackerRank. It serves as a log of my progress and a library of code snippets for various data engineering problems or SQL PROBLEMS.

The project is organized by the days of the week. Each folder contains .sql files for each day I tackled on that specific day: Naming convention of .sql files -> day-month-year.sql

• MONDAY/: Solutions to random SQL questions.
• TUESDAY/: Solutions to random SQL questions.
• WEDNESDAY/: Solutions to random SQL questions.
• THURSDAY/: Solutions to random SQL questions.
• FRIDAY/: Solutions to random SQL questions.
• SATURDAY/: Solutions to random SQL questions.
• SUNDAY/: Solutions to random SQL questions.

Each .sql file follows a simple structure:

1. Problem Description: A comment at the top explaining the task or a link to the StrataScratch problem.
2. SQL Query: The solution code.
