Lecture

Query Fusion, Nested Queries (summary)

Description

This lecture covers the use of fusion clauses to combine results from multiple queries, extracting common elements or subtracting elements from one query's results. It also explores using query results as elements in another query, either in the FROM or WHERE clause, or in other locations. Additionally, it discusses using nested queries with the IN or NOT IN operator to achieve the same results as fusion queries.
