Have you ever struggled with the pain of cascading DROPs when renaming a view in your database? I recently learned a handy trick that can save you from this headache. It turns out that if you use hierarchical or nested views, renaming a first-level view won’t trigger a cascading DROP that would knock out secondary and tertiary descendants. However, you’ll need to re-run the definition for the secondary-level view ASAP to avoid any issues.
I know, I know – nested views can be a pain to work with. But trust me, they’re worth it when you’re dealing with big ETLs that involve lots of rules. Materialized views that are refreshed concurrently can be a game-changer for non-blocking production use.
So, the next time you’re faced with a database restructuring task, remember this trick and breathe a sigh of relief. No more worrying about cascading DROPs causing chaos in your database!
