title: PL/SQL How to call a function without getting returned object
body: <p>I have a function in PL/SQL:</p>
  
  <pre><code>FUNCTION do_something
    RETURN BOOLEAN
  IS
    ...
  BEGIN
    ...
  END
  </code></pre>
  
  <p>This function can be called as such:</p>
  
  <pre><code>DECLARE
    answer BOOLEAN;
  BEGIN
    answer := do_something();
  END
  </code></pre>
  
  <p>Now, there are cases, where I don't need the returned boolean. If I don't want to get it and just write:</p>
  
  <pre><code>do_something();
  </code></pre>
  
  <p>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?</p>
