SQl-Practice-Ankit-Bansal\n# 📘 SQL Practice – Ankit Bansal YouTube Series\n\nThis repository contains my personal SQL practice based on Ankit Bansal's YouTube SQL problem series. \nInstead of copying answers, I tried to **frame my own logic** to enhance my problem-solving and analytical thinking.\n\n\n## 🔍 My Approach\n\nWhile the questions are based on playlist, I made it a rule to:\n- First solve each query **on my own** before watching the video.\n- In case of differing logic, trying to understand the flaws or creating sample datasets using AI where my logic fails. \n- Document any logic that differs from the original or adds something unique.\n\nThis helped me understand flow of logic \u0026 concept \u0026 develop deeper confidence in SQL logic — not just memorizing syntax.\n\n## 📁 Repo Structure\n- `Q1_to_Q83/` : Folder containing `.sql` files for each question.\n- `README.md`  : This file, explaining purpose and approach.\n\n## 🔧 Tools Used:\n- PostgreSQL  \n- ChatGPT, Deepseek  (AI support for sample generation \u0026 validation)\n- Data from description in youtube videos\n\n## 🧠 Topics Practiced:\n- Window functions (RANK, LAG, LEAD)\n- Aggregates \u0026 GROUP BY\n- Subqueries \u0026 CTEs\n- Joins (INNER, LEFT, SELF)\n\n## 🔗 Credit:\nBased on [Ankit Bansal’s SQL Interview Playlist] (https://youtu.be/qyAgWL066Vo?si=JVrWMEkksgWUyO6B)\n\n---\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frachit1084%2Fsql-practice-ankit-bansal","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frachit1084%2Fsql-practice-ankit-bansal","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frachit1084%2Fsql-practice-ankit-bansal/lists"}
