Oracle SQL/XML Code Example produces ORA-19207

Question

I have tried executing the Code Example shown below which has been provided by Oracle for the SCOTT/TIGER emp and dept tables (http://otn.oracle.com/tech/xml/xmldb/htdocs/sql_xml_codeexamples.html), and it produces the following error:
ORA-19207 scalar parameter string of XMLELEMENT cannot have an alias.
I have looked up the following explanation of this error message:
Cause: The scalar parameter to XMLELEMENT has been qualified with an alias.
Action: Remove the AS clause of the scalar element.
Is there a way to fix this?
SELECT XMLElement("Department",
XMLForest(deptno "DeptNo", d.dname "DeptName", d.loc "Location"),
(SELECT XMLAGG(XMLElement("Employee",
XMLForest(e.empno "EmployeeId",
e.ename "Name",
e.job "Job",
e.mgr "Manager",
e.hiredate "Hiredate"),
e.sal "Salary",
e.comm "Commission"))
FROM emp e
WHERE e.deptno = d.deptno))
FROM dept d;

Answer 1

Hi ,
The reason for getting the SQL error is that, in the SQL there is a closing bracket that is wrongly put after "Hiredate", it should have been put after the "Commission". Correct this and the SQL
will run properly.
For example , the correct script will be like is:
SET LONG 5000
SELECT XMLElement("Department",
XMLForest(deptno "DeptNo", d.dname "DeptName", d.loc "Location"),
(SELECT XMLAGG(XMLElement("Employee",
XMLForest(e.empno "EmployeeId",
e.ename "Name",
e.job "Job",
e.mgr "Manager",
e.hiredate "Hiredate",
e.sal "Salary",
e.comm "Commission")))
FROM emp e
WHERE e.deptno = d.deptno))
FROM dept d;
Hope it helps.
Thanks
