Hello,

I have to submit a document in XML format. I was also given a schema to work with but not sure how to apply it.
Our data is stored in an oracle database and sql queries are usually done on PL/SQL developer to retrieve output in excel format.
However i need output in xml format. How do i do this?
I understand that i can include items like the below..but how do i get the output in xml and how do i integrate the schema provided.

SELECT XMLElement( "DEPARTMENT"
, department_name
)
FROM departments
WHERE department_id IN (10, 20);

Your assistance will be greatly appreciated.

Here's of what you can do:
SQL> select dbms_xmlquery.getxml('select * from emp where rownum <= 3') from dual;
DBMS_XMLQUERY.GETXML('SELECT*FROMEMPWHEREROWNUM<=3')
--------------------------------------------------------------------------------------
<?xml version = '1.0'?>
<ROWSET>
   <ROW num="1">
      <EMPNO>7369</EMPNO>

      <MGR>7902</MGR>
      <HIREDATE>12/17/1980 0:0:0</HIREDATE>
      <SAL>800</SAL>
      <DEPTNO>20</DEPTNO>
