Hi,
Here below is the query which gives XML output.
SELECT XMLELEMENT(
"dept_list",
XMLAGG (
XMLELEMENT(
"dept",
XMLATTRIBUTEs(deptno AS "deptno"),
XMLFOREST(
d.deptno AS "deptno",
d.dname AS "dname",
d.loc AS "loc",
(SELECT XMLAGG(
XMLELEMENT(
"emp",
XMLATTRIBUTEs(empno AS "empno"),
XMLFOREST(
e.empno AS "empno",
e.ename AS "ename",
e.job AS "job",
e.mgr AS "mgr",
e.hiredate AS "hiredate",
e.sal AS "sal",
e.comm AS "comm"
)
)
)
FROM emp e
WHERE e.deptno = d.deptno
) "emp_list" -- This tag not required.
)
)
)
) AS "depts"
FROM dept d
WHERE d.deptno = 10;
It giving an xml output with unwanted tag. How to customize the query inorder to avoid the tag "emp_list".
And also if the values of below columns
e.empno
e.ename
e.job
e.mgr
e.hiredate
e.sal
e.comm
are null then it given an XML as <emp><emp/> instead of that my requirement is to give onely one tag with </emp>
XML OUTPUT
<ROWSET>
<DEPT>
<DEPTNO>10</DEPTNO>
<DNAME>ACCOUNTING</DNAME>
<LOC>NEW YORK</LOC>
<EMP_LIST>--not required
<ROWSET>
<EMP>
<EMPNO>7782</EMPNO>
<ENAME>CLARK</ENAME>
<JOB>MANAGER</JOB>
<MGR>7839</MGR>
<HIREDATE>09-JUN-81</HIREDATE>
<SAL>2450</SAL>
</EMP>
<EMP>
<EMPNO>7839</EMPNO>
<ENAME>KING</ENAME>
<JOB>PRESIDENT</JOB>
<HIREDATE>17-NOV-81</HIREDATE>
<SAL>5000</SAL>
</EMP>
<EMP>
<EMPNO>7934</EMPNO>
<ENAME>MILLER</ENAME>
<JOB>CLERK</JOB>
<MGR>7782</MGR>
<HIREDATE>23-JAN-82</HIREDATE>
<SAL>1300</SAL>
</EMP>
</ROWSET>
</EMP_LIST>-- Not required
</DEPT>
</ROWSET>
Thanks in advance

Hi MIchel,
Thanks for your replies.
Here is the sql query which has to be written as XML query.
Could you pls let us know how to use order by clause, joins with XML query.
SQL QUERY
SELECT

PI.question_id AS PIqid,
PI.process_id AS PIpid,
PI.innertext AS PItext,
PI.itemtype AS PItype,
PI.linkfrom AS PIfrom,
PI.linkto AS PIto,
PI.associated AS PIas,
PI.content_id AS PIc,
PI.exitpoint1_id AS PIe1,
PI.exitpoint2_id AS PIe2,
PI.exitpoint3_id AS PIe3,
PI.followoncall AS PIfoc,

where p.process_id=450
order by Ppid, PIqid, POoid;
XML QUERY IS IT EQUIVALENT TO ABOVE QUERY
select replace (replace,"PI",<A>,''),</A>,'') from (SELECT XMLAGG ( XMLELEMENT( "P",

FROM vw_liveProcessItem_Sim_v6 PI
WHERE P.process_id = PI.process_id
) "A" ) ) ) AS "PI"
FROM liveProcess_ec P
WHERE (P.process_id = 450))
Any help really appreciated.
