Userdefined functions extend SQL capabilities from "summary" of SQL and Relational Theory by C. Date
Userdefined functions are a powerful feature of SQL that allow users to extend the capabilities of the language beyond its built-in functions. These functions are defined by the user and can be used in SQL queries just like any other function. In this way, users can tailor SQL to their specific needs and requirements by creating custom functions that perform specialized tasks. One of the key advantages of userdefined functions is their ability to simplify complex queries. By encapsulating a series of operations within a function, users can create a reusable piece of code that can be called whenever needed. This can significantly reduce the amount of code that needs to be written and make queries easier to read and understand. Furthermore, userdefined functions can improve the clarity of SQL queries by abstracting away implementation details. Instead of having to write out all of the logic for a particular task each time it is needed, u...
