CREATE TEMPORARY FUNCTION local-function-name AS 'package-name.function-name'; You can then use the UDF in your Hive query or transformation. For example, if the UDF returns a text string value you can use it as shown in the following code to replace the value in the specified column of...
The general format for a function header is: R← A FUNCTION B;VAR1;VAR2 or A FUNCTION B;VAR1;VAR2 depending on whether or not a result is returned. R, the result, A, the left argument, B, the right argument are all optional. Local names, if any, are listed after the function ...
Example: User-defined function Here is an example to add two integers. To perform this task, we have created an user-definedaddNumbers(). #include<stdio.h>intaddNumbers(inta,intb);// function prototypeintmain(){intn1,n2,sum;printf("Enters two numbers: ");scanf("%d %d",&n1,&n2); ...
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...
User-defined functions can be nested; that is, one user-defined function can call another. The nesting level is incremented when the called function starts execution, and decremented when the called function finishes execution. User-defined functions can be nested up to 32 leve...
