#MySQL 8 introduces support for #AnsiSQL recursive queries with common table expressions, a powerful method for working with recursive data references. Until now, MySQL application developers have had to use workarounds for hierarchical data relationships. It's time to write SQL queries in a more standardized way, and be compatible with other brands of SQL implementations. But as always, the bottom line is: how does it perform? This presentation will briefly describe how to use recursive queries, and then test the performance and scalability of those queries against other solutions for hierarchical queries.

Bill Karwin and Markus Winand are two of the best SQL and MySQL authors I've found so far!

For some reason I hated the double recursion only to have the right order of depth because it can be solved by easily by the conumming application. As it gave the impression of beating slow.
