Stored routines in MySQL allow you to encapsulate SQL logic into reusable procedures and functions, improving efficiency and maintainability. Stored procedures execute a sequence of SQL statements, while stored functions return a value based on input parameters. These routines help reduce redundant code, enhance security by limiting direct table access, and improve performance by minimizing client-server communication.
