Did you know that using functions like `DATEPART(year, column)` in SQL Server can cause indexes to be ignored? 🔑

When you apply functions directly to columns in your WHERE clause, database engine often can’t utilize existing indexes efficiently. This is because the function needs to be applied to each row, which prevents the optimizer from using the index. This can impact query performance, especially in large datasets. 🚀

✨ **Tip:** To improve performance, consider adding a computed column that stores the materialized year. Index this column for faster query execution, especially useful in reports.

Keep your database interactions efficient and your apps running smoothly!
