		ComodoHacker on March 30, 2022 \| parent \| context \| favorite \| on: Show HN: Visualize SQL Queries I'm not sure a procedural visualization is appropriate for a declarative language like SQL. It can be misleading both on underlying concepts (sets and relations) and actual query execution. I'd more like to see a visualization it terms of tuples, sets and operations on them leading to result set.

I guess this could be a teaching tool if you focus on just selecting keywords from the dropdown, but in general most SQL engines' EXPLAIN features are leagues more useful than this.

Idea was to supplement the many websites that do explain SQL this way. But yes, I agree with that statement.
