"Most efficient" means "the fewest yellow nodes". Deleting records is cheating 🤓 Playground: https://app.querydoctor.com/ixr/share/uaffnLYq-V3T Good luck!20 Mar 2025 23:21 +0000at://did:plc:pdht6uva62v2xqmac7crybc2/app.bsky.feed.post/3lkttmxvaok2xhttps://bsky.app/profile/querydoctor.com/post/3lklxj4bfgc2iThis @mattermost.bsky.social article is fascinating, row value comparisons are nifty! Interesting to see IndeX-Ray reveal the unbounded index scan. The other query correctly bounds the index scan to minimize it. https://mattermost.com/blog/making-a-postgres-query-1000-times-faster/ Playground: https://app.querydoctor.com/ixr/share/ZlKBVsPZ1BNR17 Mar 2025 20:09 +0000at://did:plc:pdht6uva62v2xqmac7crybc2/app.bsky.feed.post/3lklxj4bfgc2ihttps://bsky.app/profile/querydoctor.com/post/3ljpworcqbc2yCan the code underlining approach used by IDEs be applied to show indexing problems directly on SQL text? @simp.engineer thinks so! See how his latest work magically surfaces scan type details from query execution on the relevant clauses in the query itself: https://app.querydoctor.com/ixr/share/w3FpWSMiRtAe06 Mar 2025 16:40 +0000at://did:plc:pdht6uva62v2xqmac7crybc2/app.bsky.feed.post/3ljpworcqbc2yhttps://bsky.app/profile/querydoctor.com/post/3lhm3m7xjgs2iWhat better first post than to announce a feature? How the DB handles the WHERE clause of a query is now shown directly in the diagrams! Easily see how the logic of SQL is translated into a plan the DB can use to find the results.
