PL/SQL How to call a function without getting returned object

declaration, function, oracle, plsql, return-value

Solution

Very simple: create a procedure which covers this function

PROCEDURE do_something
IS
  dummy boolean;
BEGIN
  dummy := do_something();
END;

Sorry, but this is the only way in PL/SQL. This language is very strict in definitions of procedure and function and you cannot make a function call without handling the result. But you can make a procedure as it is shown in example above.

It will define automatically where to choose the function and where the procedure.

EDIT

As far as there are people who do not trust me (sometimes I really tell bad things so doubts are allowed :) ) this is the test:

declare
  myresult boolean;

  function do_something return boolean
    is
  begin
    return true;
  end;

  procedure do_something
    is
      dummy boolean;
  begin
    dummy := do_something();
  end;
begin
  myresult := do_something();

  do_something();
end;

works well.

Problem

I have a function in PL/SQL: ``` FUNCTION do_something RETURN BOOLEAN IS ... BEGIN ... END ``` This function can be called as such: ``` DECLARE answer BOOLEAN; BEGIN answer := do_something(); END ``` Now, there are cases, where I don't need the returned boolean. If I don't want to get it and just write: ``` do_something(); ``` I get PLS-00306 (wrong number of types of arguments in call to DO_SOMETHING) Is there a way to call it without declaring and setting a new boolean, which I will never use in this case?
