How to execute stored function in oracle pl/sql?

@hal.littel 

To execute a stored function in Oracle PL/SQL, you can use the following syntax:

1
2
3
4
5
6

DECLARE
  result_value return_datatype;
BEGIN
  result_value := function_name(parameter1, parameter2, ...);
  -- You can then use the result_value in your PL/SQL code
END;

Replace return_datatype with the data type that the function returns, function_name with the name of the stored function, and parameter1, parameter2, ... with the parameters required by the function.

For example, if you have a stored function named get_employee_salary that takes an employee ID as a parameter and returns the salary of the employee, you can execute it in PL/SQL as follows:

1
2
3
4
5
6

DECLARE
  emp_salary NUMBER;
BEGIN
  emp_salary := get_employee_salary(1001);
  DBMS_OUTPUT.PUT_LINE('Employee Salary: ' || emp_salary);
END;

Note that you need to call the stored function within the PL/SQL block and assign the result to a variable that matches the data type of the return value of the function. You can then use this variable within your PL/SQL code.
