SELECT XMLELEMENT("Cust", XMLFOREST(d.ID,
                                    d.request_id,
                                    d.first_name,
                                    d.last_name)) "Cust Element"
FROM  MyTable d
;

This query returns these 4 fields in XML. If I want to write a query that will get all the columns into the XML without being explicitly named...

This seems to work, but I'm not sure if it is the most elegant solution...

select value (e).GETCLOBVAL() as "xmltype"
FROM TABLE(XMLSequence(Cursor(SELECT * FROM MYTABLE))) e;

Thanks for your advice...

I do not see any issue with this.  My table lookup had 2 fields.

select value (e).GETCLOBVAL() as "xmltype"
FROM TABLE(XMLSequence(Cursor(SELECT * FROM lookup))) e;

but you need to note that it is giving a ROW tag for each record if you use this.

 <ROW>
  <CODE>INDEFLY</CODE>
  <CODEWORD>indefinitely</CODEWORD>
 </ROW>

but if you do it with this "SELECT XMLELEMENT("MYOWNTAG", XMLFOREST(code, codeword)) "Cust Element" FROM  lookup", we can get it with the tag name wanted as we wanted.

<MYOWNTAG>
  <CODE>INDEFLY</CODE>
  <CODEWORD>indefinitely</CODEWORD>
</MYOWNTAG>

Thanks
