Master Detail Report for PDF Printing

Question

Dear All,
       While trying to create a master detail report using Oracle APEX 4.2 and BI Publisher. I tried creating report queries and report layout following the below mentioned steps.
CREATE TYPE emp_row AS OBJECT (
  EMPNO NUMBER(4),
  ENAME VARCHAR2(10),
  JOB VARCHAR2(9),
  MGR NUMBER(4),
  HIREDATE DATE,
  SAL NUMBER(7,2),
  COMM NUMBER(7,2)
CREATE TYPE emp_tab AS TABLE OF emp_row;
CREATE TYPE dept_row AS OBJECT (
  DEPTNO NUMBER(2),
  DNAME VARCHAR2(14),
  LOC VARCHAR2(13),
  EMP_LIST emp_tab
SELECT SYS_XMLAGG (
  SYS_XMLGEN(
  dept_row(
  d.deptno, d.dname, d.loc,
  CAST(MULTISET(SELECT e.empno, e.ename, e.job, e.mgr, e.hiredate, e.sal, e.comm
  FROM emp e
  WHERE e.deptno = d.deptno) AS emp_tab)
  SYS.XMLGENFORMATtYPE.createFormat('DEPT')
  ) AS "XML_QUERY"
FROM dept d
WHERE d.deptno = 10;
Though the above steps generates xml output while trying to generate in APEX it says unsupported datatype. Tried using DBMS_LOB as well no luck. Any inputs will be quite helpful. Should there be any other way to incorporate master detail report printing in APEX kindly advise.
Thanks
Ahmed

Hi Ahmed_Jed,

Thanks Kiran for your prompt response. I tried following the steps already using this link (How To Create a Master-Detail PDF Report) somehow the detail record was not getting processed perhaps was trying to generate xml data using the above query. Any other reference will be highly appreciated.

    Well the problem lies here:
SELECT SYS_XMLAGG (
  SYS_XMLGEN(
  dept_row(
  d.deptno, d.dname, d.loc,
  CAST(MULTISET(SELECT e.empno, e.ename, e.job, e.mgr, e.hiredate, e.sal, e.comm
  FROM emp e
  WHERE e.deptno = d.deptno) AS emp_tab)
  SYS.XMLGENFORMATtYPE.createFormat('DEPT')
  ) AS "XML_QUERY"
FROM dept d
WHERE d.deptno = 10;
    The Report Query itself generates XML data (in the required BI Publisher format). So, no need to generate it like this.
    As you are using table functions your query should be of the type:
SELECT EMPNO
            , ENAME
            , JOB
            , MGR
            , HIREDATE
            , SAL
            , COMM
    FROM TABLE ( EMP_PKG.GET_EMPLOYEES ( :PXX_DEPTNO ))
    where EMP_PKG.GET_EMPLOYEES is packaged table function which returns the Object Table of type EMP_TAB mentioned above.
    When you test the above Report Query with sample DEPTNO, it will generate the sample XML, which you can use to generate Report Layout in RTF format using BI Publisher Desktop.
    Hope this helps!

Kiran
