A function is a block of code that performs a specific task. C allows you to define functions according to your need. These functions are known as user-defined functions. For example: Suppose, you need to create a circle and color it depending upon the radius and color. You can create t...

User-defined functions can't pass intotoscalar()invocation information that depends on the row-context in which the function is called. User-defined functions that return a tabular expression can't be invoked with an argument that varies with the row context. ...
And I use normal functions like these /// I use _x_ instead of normal x to prevent from IntelliSense /// a = min(a, b) template<class _A_, class _B_> void minimize(_A_ &_a_, const _B_ &_b_) { if (_a_ > _b_) _a_ = _b_; } /// return true if (a is minim...
The Db2 Big SQL environment in Hadoop includes the Hive user-defined functions package. This set of functions is an optional package that you can install to use some of the Hive open source user-defined functions in your Db2 Big SQL queries. You can also use the package as an example to...
User-Defined Functions, or UDFs, are database objects the closely mimic the semantics of functions in programming languages. Like a function in C#, UDFs can include a variable number of input parameters and return a value of a particular typ...

Somwtimes we use different user deffined data structures in C/C++. For example, structdata1{stringname;intid;doublemarks;} We can also use operator overloading and user defined functions in structers. structdata2{stringname;intid;doublemarks;booloperator<(constdata&a)const{returnid...
