Dbms_xmlquery.getxml problem

Question

SQL> select * from emp;
EMPNO ENAME JOB MGR HIREDATE SAL COMM --------- ---------- --------- ---------- --------- ---------- ---------- ---------- --------- ------------
7369 SMITH CLERK 7902 17-DEC-80 800 20
14 rows selected.
SQL> select dbms_xmlquery.getxml('select * from emp where rownum<2') from dual;
DBMS_XMLQUERY.GETXML('SELECT*FROMEMPWHEREROWNUM<2')
<?xml version = '1.0'?>
<ROWSET>
<ROW num="1">
<EMPNO>7369</EMPNO>
I'm just wondering why the query output XML has EMPNO alone, and not the other column data.Please help.
Thanks,
Bhagat

It's because of the parameter settings in SQL*Plus. It's just not showing the whole output for you...
SQL> select dbms_xmlquery.getxml('select * from emp where rownum<2') from dual;
DBMS_XMLQUERY.GETXML('SELECT*FROMEMPWHEREROWNUM<2')
<?xml version = '1.0'?>
<ROWSET>
   <ROW num="1">
      <EMPNO>7369</EMPNO>
SQL> set long 2000
SQL> select dbms_xmlquery.getxml('select * from emp where rownum<2') from dual;
DBMS_XMLQUERY.GETXML('SELECT*FROMEMPWHEREROWNUM<2')
<?xml version = '1.0'?>
<ROWSET>
   <ROW num="1">
      <EMPNO>7369</EMPNO>
      <ENAME>SMITH</ENAME>
