title: Creating dynamic parameter stored procedure
body: <p>Is it possible to create a dynamic value that can hold any data type value in stored procedures in firebird? Something like: </p>
  
  <pre><code>SET TERM ^ ;
  
  CREATE PROCEDURE something(variable_a dynamic)
  RETURNS (status int)
   AS
  BEGIN
  -- ....
  END^
  
  SET TERM ; ^
  </code></pre>
  
  <p>Thank you.</p>
