Oh, you probably wouldn't really want to accept this PR as it's better that your GitHub repo looks like the code in the book. But a PR was a way for me to "share" this with you. Thanks again! |

Great book ! ! !
I thought you might be interested in this alternative approach to writing queries with sub-queries, namely using CTEs (or the WITH clause). I find that CTE queries with reasonably good intermediate names, that get "enriched" and "transformed" on the way "down," make complex queries easier to grok.
Anyhow, I'm learning a lot from your book and use this technique personally to understand the "steps" of a complex query.
Thanks for writing an excellent book!
