In this video, I dive into some key signs that indicate your SQL queries might benefit from using dynamic SQL. I cover common scenarios like heavy reliance on local variables in where clauses, conditional logic based on parameter values, and complex join conditions that vary depending on the data. By highlighting these issues and demonstrating how to address them with dynamic SQL, I aim to help you improve query performance and maintainability. Whether you're a seasoned SQL Server professional or just starting out, understanding when and why to use dynamic SQL can significantly enhance your database management skills.
