title: Replacing part of an Oracle package
body: <p>I need to modify one procedure from within a package. I need to touch both the declaration and the implementation. As I am maintaining patch files for each modification, I would like the changes to be minimal.</p>
  
  <p>Can I update the package with just the changed procedure ( if yes, how ? ) , or do I need to supply the complete package definition and implementation?</p>
