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