Retrieving Column Names from a Query

Question

I need to be able to generate XML that looks like this:
<Categories>
<Category Name='Arrivals'/>
<Category Name='Departures'/>
<Category Name='Unused'/>
<Category Name='Out of Commission'/>
</Categories>
Where the name attribute value is the name of columns in a query. For example, a standard SQL query might look something like this:
select
year, arrivals, departures, unused, out_of_commission
from
some_table
I am able to generate the XML that represents the data just fine. However, my vended application is requiring this column header information. I've browsed and searched the XMLDB documentation but could not see a way to retrive the column names returned by the query. I think I Just need to be pointed in the right direction.
Thanks,
Steve

Answer 1

What technique are you itending using to generate the XML ?.
Does something like this work
select xmlelement("Categories",
xmlelement("Category", xmlattributes('Arrivals' as "Name"), Arrivals),
xmlelement("Category", xmlattributes('Departures' as "Name"), Departures),
xmlelement("Category", xmlattributes('Unused' as "Name"), Unsused),
xmlelement("Category", xmlattributes('Out Of Commission' as "Name"), Out_of_Commission)
from some_table
