HUDay 6/21 — Window Functions (Basics) ✅
Article: https://www.thoughtspot.com/sql-tutorial/sql-window-functions#TS-sql-editor-section
SQL Plan: https://www.notion.so/21-Day-SQL-Pro-Challenge-Data-Engineer-Edition-2eb5aa6ddc6180bb972dd204e9532c03#2eb5aa6ddc618083bdebe6e72fedd73f
I solved three SQL questions:
1) Second Highest Salary
This is an easy and common question, but I intentionally solved it using a window function (DENSE_RANK) instead of other approaches. The main learning here was understanding how to return only one row in the final output when window functions naturally return multiple rows.
2) Rank Scores
This question was straightforward and focused on ranking values based on score. I used DENSE_RANK() with proper ordering, which made it a clean and simple solution.
3) Two-Week Rolling Average (DataLemur)
This was the most interesting question today. It introduced the concept of window frames. The key learning was how to define a rolling window — in this case, calculating a rolling average over a fixed number of days — using the correct window range inside a window function.
I also did a quick revision by re-solving one question from Day 4, just to keep earlier concepts fresh.
Day 6 completed. Moving on to Day 7
