Have you ever wanted to create a recursive query, but didn't see how to do it? Now you no longer have to cringe when asked to turn a self-join table into a tree path outline or level hierarchy.
Each of these goals is now just one query if you use a common table expression (CTE). Using a CTE offers the advantages of improved readability and ease in maintenance of complex queries. The query can be divided into separate, simple, logical building blocks. These simple blocks can then be used to build more complex, interim CTEs until the final result set is generated.
