Hierarchical Queries are a powerful tool for retrieving data from a relational database. They allow you to query data from multiple tables, even if there is no direct relationship between them, by using a common column that links the tables together. This can be useful for a variety of tasks, such as generating reports, performing data analysis, and creating complex data visualizations.
