Types of functions This section describes the differences between scalar functions, table-valued functions, and system functions. Scalar functions User-defined scalar functions return a single data value of the type defined in the RETURNS clause. For an inline scalar function, the returned scalar valu...

User-Defined Functions and TypesIn this chapter, I'll present recipes for user-defined functions and types. User-defined functions(UDFs) allow you to encapsulate both logic and subroutines into a single function that can then be...doi:10.1007/978-1-4302-4201-7_18Brimhall, Jason...
定义UserDefinedFunction 类: UserDefinedFunction 是表示用户自定义函数的类,它接受函数对象 f、返回值类型 dataType 和输入参数类型 inputTypes。 构造函数参数 f: AnyRef:表示用户定义的函数对象。这个函数可以是任意类型(AnyRef),例如匿名函数、Lambda 表达式或方法引用。 dataType: DataType:表示用户定义的函数的返回...

Python: user defined function: In all programming and scripting language, a function is a block of program statements which can be used repetitively in a program. In Python concept of function is same as in other languages.

SQL SERVER中的用户定义函数(User Defined Functions 简称UDF)分为标量函数(Scalar-Valued Function)和表值函数(Table-Valued Function)。其中表值函数又分为Inline table-valued functions和Multistatement table-valued functions。 用户定义函数(UDF)在 SQL Server 中发挥重要的作用。用户定义函数可以用于执行复杂的逻辑...
