Hello,

I have a problem creating an XML file from a join involving about ten tables. We are on Oracle 10g 10.2.0.4. My File will have to look like the following:-

<?xml version="1.0" encloding="utf-8"?>
<TRACS type="XXXX" data="XXXXX" version="1.0" action-code="ADD">
<department>
<department-id>XXXX</department_id>
<employee>
<first-name>JJJJJ</first_name>
<last-name>LLLL</last_name>
<encounter measure="MMM">
<st-date>04-02-2007</st-date>
<emp-id>92993</emp-id>
<emp-ssn>388299289</emp-ssn>
</encounter>
</employee>
<first-name>EEEE</first_name>
<last-name>WWWW</last_name>
<encounter measure="MMM">
<st-date>04-22-2007</st-date>
<emp-id>92993</emp-id>
<emp-ssn>388299289</emp-ssn>
</encounter>
</employee>
</department>
</TRACS>

The second line is what I have a problem with. I have tried doing the following:
SELECT XMLElement( "TRACS",XMLAttributes(''OUTPATIENT'' as "type", ''CLINICAL'' as "data", ''1.0'' as "version", ''ADD'' as "action-code"), (XMLELEMENT("provider", XMLForest(DECODE(a13.HOSPITAL_ID,''C'',110078,''E'',110010) as "provider-id"),xmlagg(XMLELEMENT( "patient", XMLForest( a18.PATIENT_FIRST_NM "first-name", a18.PATIENT_LAST_NM "last-name" ),XMLELEMENT("encounter", XMLATTRIBUTES ( ''HOP-AMI'' AS "measure-set"), XMLForest ( a110.DAY_ADMIT_DESC as "encounter-date", a18.PATIENT_ID as "patient-id",
a12.MEDICAL_RECORD_NBR as "medical-record-nbr"))))))) as "provider"....

but it repeats the header for each record. I want just ONE such header for the whole document. I am writing this info into a CLOB column in a table first.

Please let me know if you have something that will work.
Thanks

might be easier to help you if you posted a working example for use to modify.

Try refactoring your query using a nested select of some sort, such that you select from dual as the outer query. The problem item will still repeat for each row but there will only be one row.

Well, here it is.
Declare

dbms_xmlgen.setNullHandling(ctx,dbms_xmlgen.empty_tag);

dbms_xmlgen.setRowsetTag(ctx,'provider');

result := DBMS_XMLGEN.getXML(Ctx);
--
INSERT INTO UHC_DATA_CLOB VALUES ('HIC',result, sysdate);
commit;
DBMS_XMLGEN.closeContext(Ctx);

end;

What I want is something like the following:-

<medical-record-nbr>1687914</medical-record-nbr>
</encounter>

Hope you have a solution to this issue...

have about sharing some table creates and insert statements. No one will write any code on your behalf to demonstrate ideas, without these.

I don't know if I am understanding you. Do you want me to send you Create and Insert stmts for all the embedded tables in the Query or just the one for the lone XML document insert?

The gist of it is I am getting three "provider" tags when I only need one. I can't set setrowsettag and setrowtag both to null. The tags inside are the problem tags.

Do let me know what exactly you are looking for and I will try to comply.

Thx

I am sorry but I am not really following your problem. Why does this not work for you?

SQL> 
SQL> select dbms_xmlgen.getxml
  2  (
  3    'select 110078 provider_id'
  4  ||'      ,cursor('
  5  ||'               select ''Brittany'' first_name,''Thomas'' last_name'
  6  ||'                     ,cursor('
  7  ||'                             select ''HOP-SURGERY'' measure_set,''05/31/2008'' encounter_date,111745603216 patient_hic_number'
  8  ||'                             from dual'
  9  ||'                            ) encounter'
 10  ||'               from dual'
 11  ||'             ) patient'
 12  ||' from dual'
 13  )
 14  from dual
 15  /

DBMS_XMLGEN.GETXML('SELECT110078PROVIDER_ID'||',CURSOR('||'SELECT''BRITTANY''FIR
--------------------------------------------------------------------------------
<?xml version="1.0"?>

1 row selected.

Well, the tag "encounter" should exactly look like the following:-

<encounter measure-set="HOPI-SURGERY">
.....
</encounter>

It should have the value measure-set="HOPI-SURGERY" as its attributes.

I have something like a 15 table join and I am not sure if this will do it. I am going to try it nonetheless.

Thanks
