"Hey all, just finished re-working a clunky query and I gotta say, I'm loving the simplicity of my new subquery setup. I had a nasty inner join with a derived table, but swapping it for a common table expression (CTE) and a WHERE IN clause cleaned it up nice and tidy. What about you guys, any savagely optimized subquery tricks to share?"

"Ahaha, savage subqueries, nice thread title OP. For those who don't know, a simple trick I use is to break down complex queries into smaller pieces, like creating temp tables or CTEs to make it easier to read and optimize. Anyone else got some query optimization secrets to share?"

"Yo, been there, done that. I recall using a technique called 'Common Table Expressions' (CTEs) to optimize a query that was taking ages to load. Helped reduce the execution time by over 70% in one go."

"Just implemented a subquery that was using a JOIN instead of EXISTS and saw a 20% boost in query speed. I've also been experimenting with rewriting queries to use Common Table Expressions (CTEs) for improved readability."

"Dude, I've been dealing with this issue in my Ethereum blockchain explorer project and I swear, using CTE (Common Table Expressions) made my queries run in like 80% less time. It's like a magic trick or something. Anyone else had success with indexing?"

"Lol, for brutal subquery optimization, I swear by rewriting complex joins into CTEs or temporary tables. It might look uglier but it saves on execution time and memory. Anyone else have some mad query hacks to share?"

"just threw in a CTE to cache a subquery that was getting repeated over 1000 times in a query and it shaved off a whole second. anyone else use CTEs to optimize performance? also, what's everyone's take on index maintenance?"
