Welcome, seeker of wisdom! We know, you've been having trouble figuring out why that pesky database query isn't running in 4.5 seconds or less. Or perhaps you've been wondering why your reports are so slow, they make your eyes bleed.
Don't be a hero, index those tables! It's like putting a superpower in your database. Your queries will thank you, your users will thank you, and your coffee machine will thank you (because you won't be yelling at it all day).
Avoid the dark side of SQL - excessive use of subqueries! Instead, use the power of set operations to rule them all. You know, like a SQL Jedi Master.
Caching is your friend, especially when it comes to complex queries! Store those results, and let your users live in the fast lane. Or, you know, the highway.
