Comment/Recommendation
Exercise 1: SQL Query with Joins and Aggregates (2/2)
- Your queries are accurate and efficient. You clearly demonstrated an understanding of SQL joins, aggregate functions, and how to combine them effectively. Great job on providing clear explanations as well!
Exercise 2: Using Subqueries and Aggregate Functions (2.5/3)
- In Query 2, your use of subqueries is well-executed, but providing more detail about how NULL values are managed could add clarity to your explanation. Otherwise, the subqueries and aggregate functions are correctly applied.
Exercise 3: Write the SQL Queries (4/5)
- The SQL queries presented are well-crafted, showing a solid understanding of the problem. However, one of the queries could be optimized by slightly adjusting the use of the
GROUP BYclause to improve performance.
