Video Description
In this video let us solve a real SQL interview problem. This problem is to find the hierarchy of employees. We shall first understand the problem statement and the given data before solving the problem. During the video, we shall also see how to debug a recursive SQL query. We shall try to come up with the different queries SQL generates during each iteration of the recursive SQL query. This will hopefully give you a complete understanding of how recursive SQL query works. 🔴 My Recommended courses 👇 ✅ Learn complete SQL: https://learnsql.com/?ref=thoufiqmohammed ✅ Practice SQL Queries: https://www.stratascratch.com/?via=techTFQ ✅ Learn Python: https://codebasics.io/courses/python-for-beginner-and-intermediate-learners?refId=70170e4c-7511-4c83-b769-c5cc8339c731 ✅ Learn Power BI: https://codebasics.io/courses/power-bi-data-analysis-with-end-to-end-project?refId=4b1e1886-3252-4bf1-86f4-7d603dab692f 🔴 WATCH MORE VIDEOS HERE 👇 ✅ SQL Tutorial - Basic concepts: https://www.youtube.com/playlist?list=PLavw5C92dz9HQQ_COgGb7kf_1H8UWUBxO ✅ SQL Tutorial - Intermediate concepts: https://www.youtube.com/playlist?list=PLavw5C92dz9FD9XspliRM_HZM_jK7tkii ✅ SQL Tutorial - Advance concepts: https://www.youtube.com/playlist?list=PLavw5C92dz9GbmgiW4TWVnxhjMFOIf0Q7 ✅ Practice Solving Basic SQL Queries: https://www.youtube.com/playlist?list=PLavw5C92dz9F66P3GFo5O6nJ4DfZNhVsp ✅ Practice Solving Intermediate SQL Queries: https://www.youtube.com/playlist?list=PLavw5C92dz9EIYmNXJ8ZtQ1bmLIpt0SpV ✅ Practice Solving Complex SQL Queries: https://www.youtube.com/playlist?list=PLavw5C92dz9Fahr7taauUx5RnTfuGyL-- ✅ Data Analytics Career guidance: https://www.youtube.com/playlist?list=PLavw5C92dz9FDsr995DjwCy9XNaIukb8P ✅ SQL Course, SQL Training Platform Recommendations: https://www.youtube.com/playlist?list=PLavw5C92dz9GqF1Q_zn8KnYvFgtEOh-2n ✅ Python Tutorial: https://www.youtube.com/playlist?list=PLavw5C92dz9FePZXIo4jpsupqp3X0w2SW ✅ Git and GitHub Tutorial: https://www.youtube.com/playlist?list=PLavw5C92dz9EI1MPlqqDpe3bgr8RJZE0b ✅ Data Analytics Projects: https://www.youtube.com/playlist?list=PLavw5C92dz9HwT_uStsDdJbuBOt_XD0ch THANK YOU, Thoufiq
