This video isn't just about technical details. Discover how to master the art of communicating your technical skills through this AI-created conversation.

Are you confident your SQL Server dynamic SQL is both secure AND performant? Many developers unknowingly use an anti-pattern with EXECUTE and string variables that puts their databases at risk of SQL Injection and silently causes plan cache bloat.

I break down these threats and provide the proven solution: parameterized dynamic SQL with sp_executesql. Plus, learn how Microsoft Defender for SQL can help you detect active attacks. Upgrade your SQL game!
