Jul 29, 2024 · User-defined functions are routines that accept parameters, perform an action, and return the result as a single scalar value or a result set.

SQL User-Defined Functions (UDFs) are custom functions created by users to perform specific tasks within a relational database management system (RDBMS). These functions encapsulate a set of SQL statements, allowing users to execute complex operations, calculations, or data manipulations with a single function call.

Feb 25, 2020 · You can create several user-defined objects in a database. One of these is definitely user-defined functions. When used as intended, they are a very powerful tool in databases.
