Stop Obsessing Over Elegant Syntax if it's Killing Performance 🏗️

The "Glass Bridge" of CTEs (Common Table Expressions) looks beautiful in your editor, but for production-grade scale, it's often a liability. When you are dealing with millions of rows, readability shouldn't come at the cost of system stability.

The Problem: CTEs are often not indexed and can become a memory nightmare on massive datasets, causing your queries to "choke" just when you need them most.

The Solution: The "Iron Fortress" of Temp Tables. By leveraging TempDB, you gain access to actual indexing and statistics that the SQL optimizer needs to execute efficiently.

Why Temp Tables Win: 🛠️ Real indexing support for faster joins. 📊 Better statistics for the query optimizer. 🚀 Up to 80% reduction in query execution time. 📈 Scalability designed for production-grade environments.

Stop building fragile bridges and start building fortresses.
