title: How can I avoid the warning fom an unused parameter in PLSQ?
body: <p>Sometimes, in PL SQL you want to add a parameter to a Package, Function or Procedure in order to prepare future functionality. For example:</p>
  
  <pre><code>create or replace function doGetMyAccountMoney( Type_Of_Currency IN  char := 'EUR')   return number 
  is
    Result number(12,2);
  begin
   Result := 10000;  
  IF char &lt;&gt; 'EUR' THEN
     -- ERROR NOT IMPLEMENTED YET
    END IF;  
      return(Result);
  end doGetMyAccountMoney;also 
  </code></pre>
  
  <p>It can lead to lots of warnings  like</p>
  
  <pre><code>Compilation errors for FUNCTION APPUEMP_PRAC.DOGETMYACCOUNTMONEY
  Error: Hint: Parameter 'Currency' is declared but never used in 'doGetMyAccountMoney'
  Line: 1
  </code></pre>
  
  <p>What would be the best way to avoid those warnings? </p>
