Should you expose a Stored Procedure via XMLType?

When you want to expose your Stored Procedure to the "outside world", should you do this using XMLType? As always, the correct answer is "it depends".
For this example I will use a Package containing two functions, the signature of the package is as follows:

create or replace package emps_pkg
is
   function get_department_xml (p_department_no in number)
      return xmltype;

   function get_departement_ot (p_department_no in number)
      return all_departments_ot;
  
end emps_pkg;

Creating an XMLType based on Object Types

Sometimes it is necessary to create a Stored Procedure which returns an XMLType, like when you want to expose the Stored Procedure to the "outside world", like via a Mediator. There are several options to create an XMLType. In this blogpost I will show you two ways of doing this. First the "regular" way using XMLElement, XMLForest and XMLAgg. Second using Object Types which are being converted to XMLType.

Change the XML Prolog using XMLROOT

About a month ago I wrote about using XMLType and RefCursor to rename the ROW and ROWSET tags. You can find that article by clicking here.
For the same project described in that article the XML prolog needed to include the encoding as well. Just in case you are unfamiliar with the XML Prolog, this is it:

<?xml version="1.0"?>

In Oracle 10g there is an XMLROOT function which creates the XML Prolog for you, but it doesn't allow you to add encoding to it. At least not by specifying parameters, but there is a way to do this, read on..

XMLType, RefCursor and renaming ROW and ROWSET tags

The project that I'm currently involved in uses XML to send data to a reporting engine which parses the XML and creates a pretty PDF report.
In order to do this some "generic" packages were created to create the XML based on the content of a RefCursor. Works like a charm. Just call the function with a RefCursor and get an XML back.
The problem they initially had was that the XML returned uses the ROWSET and ROW tags, while they wanted different tags. No problem, some REPLACE function would do the job, and that worked fine. Until last week that was...
