How do you write a recursive function in PL SQL?
A recursive function is simply one that calls itself. SQL> create or replace 2 function factorial ( 3 n positive 4 ) return positive 5 is 6 begin 7 if n = 1 then 8 return n; 9 else 10 return n * factorial(n-1); 11 end if; 12 end; 13 / Function created.
What is the easiest way to find the factorial of a number?

How do you calculate 5 factorial?
What is the meaning of 5 factorial? The meaning of 5 factorial is that we need to multiply the numbers from 1 to 5. That means, 5! = 5 × 4 × 3 × 2 × 1 = 120.
How do you find the recursive factorial?
The factorial function can be written as a recursive function call. Recall that factorial(n) = n × (n – 1) × (n – 2) × … × 2 × 1. The factorial function can be rewritten recursively as factorial(n) = n × factorial(n – 1).
What is the factorial for 20?

How do you call a function in PL SQL?
To call a function you have to pass the required parameters along with function name and if function returns a value then you can store returned value....Calling PL/SQL Function:DECLARE.c number(2);BEGIN.c := totalCustomers();dbms_output. put_line('Total no. of Customers: ' || c);END;/
Does PL SQL support recursion?
Answer: Yes, PL/SQL does support recursion via function calls. Recursion is the act of a function calling itself, and a recursive call requires PL/SQL to create local copies of its memory structures for each call.
What is trigger in PL SQL?
A PL/SQL trigger is a named database object that encapsulates and defines a set of actions that are to be performed in response to an insert, update, or delete operation against a table. Triggers are created using the PL/SQL CREATE TRIGGER statement.

What is a factorial in Python?
To find the Python factorial of a number, the number is multiplied with all the integers that lie between 1 and the number itself. Mathematically, it is represented by “!”. Thus, for example, 5! will be 5 x 4 x 3 x 2 x 1, that is 120. Factorial for negative numbers is not defined.
