- SQL provides three powerful functions: window functions, common table expressions (CTEs), and stored procedures. 1. Window functions allow grouping and sorting operations without changing the data set. 2.CTEs provide temporary result sets to simplify complex queries. 3. Stored procedures are precompiled SQL code blocks that can be executed repeatedly to improve efficiency and consistency.
