executing a function in sql plus

Question

I created a function in oracle that inserts records in specific tables and return an output according to what occurs within the function. e.g (ins_rec return number)

How do I call this function and see its output in sql plus

Answer 1

declare   x number; begin   x := myfunc(myargs); end; 

Alternatively:

select myfunc(myargs) from dual; 

Answer 2

One option would be:

SET SERVEROUTPUT ON  EXEC DBMS_OUTPUT.PUT_LINE(your_fn_name(your_fn_arguments));
