Xml query foramt..

hi all,
i need help with the following query,
select xmlelement("l", xmlattributes(lxxxx_code as "id", xxxx_FLAG AS "b" , dbms_lob.substr(text,4000,1) as "d")) from wrk_xxxx_xx_l;
the out put of the query should look like
<l id="en_US" b="0" d="BUSH, STABILIZER"/>
i am able to xmlcollect and xml attribute and generate following output
<l id="en_US" b="0" d="BUSH, STABILIZER"></l>
is there a way we can generate the output that i wanted through xml..

Use XMLSerialize function with INDENT option, if your version supports it (requires 11.1) :
SQL> select xmlserialize(document
2 xmlelement("l",
3 xmlattributes(
4 '1' as "id"
5 , '0' as "flag"
6 )
7 )
8 as clob indent
9 )
10 from dual ;
XMLSERIALIZE(DOCUMENTXMLELEMEN
<l id="1" flag="0"/>

Problem in xml query

Hi
I am working on BLS and having problem in xml query.I want to perform some calculation over xml columns.Than total of this as a new column.I can do this part in logic editor itself but can i do these both task by XSLT.
Can be made our own XSLT for this ?
I am feeling kind of fear to xslt. Can anybody help me in this.
Thanks a lot in advance
thomas

Ram,
In xMII there is a list of predefined xslt transforms that do something similar to what you are explaining. The 3 that I think may be what you are looking for are
they are under Calculation Transformations and Subtotal Transformation take a look at these and tell me if they are doing what you want to accomplish. In the xMII help file do a search on Inline Transforms or navigate to Advanced Topics -> Inline Transforms -> Predefined Inline Transforms. In this section there are examples of how to use these transforms and apply them in the query templates. If this is not what you are looking for can you explain in a little more detail along with a simple example of how you want this transform to work. Also why do you want to use xslt if you can already accomplish this in BLS?

Converting Oracle XML Query Result in Java String by using XSU

Hi,
I have a problem by converting Oracle XML Query Result in Java
String by using XSU. I use XSU for Java.
For example:
String datum=new OracleXMLQuery(conn,"Select max(ps.datum) from
preise ps where match='"+args[0]+"'");
String datum1=datum;
I become the following error:
Prototyp.java:47: Incompatible type for declaration. Can't
convert oracle.xml.sql.query.OracleXMLQuery to java.lang.String.
Can somebody tell me a method() for converting to solve my
problem??????
Thanks

Hmmm.. Pretty basic just look at the example:
OracleXMLQuery qry = new OracleXMLQuery(conn,"Select max(ps.datum) from preise ps where match='"+args[0]+"'");
String xmlString = qry.getXMLString();

How to tune the performance of Oracle SQL/XML query?

Hi all,
I am running Oracle 9i and like to run the following Oracle SQL/XML query. It takes about 3+ hour and still not finish. If I get rid all the XML stuffs it only take minutes to run. Does anybody know how to what's the reason of this slow and how to tune it?

Help Needed XML query

I have troubles with my XML query. It returns to many results and double results.
My code
select xmlelement("test", XMLAgg(xmlelement("Customer", XmlAttributes(a.CUSTOMER_ID "cid"))),
XMLAgg(xmlelement("Account", xmlagg(xmlelement("Account", b.ACCOUNT_ID) ))),
XMLAgg(xmlelement("ServicePoint", xmlagg(xmlelement("sp", c.SPID) ))) ).extract('*').getstringval() xml
From DM_SERVICE_POINT c, DM_CUSTOMER a, DM_ACCOUNT b where a.CUSTOMER_ID = b.CUSTOMER_ID And a.CUSTOMER_ID=c.CUSTOMER_ID AND a.CUSTOMER_ID='15058'
group by a.CUSTOMER_ID
i have 1 customer id in the table dm_customer, 2 account_id 's that are linked to customer_id with a FK. DM_Servicepoint contains 6 rows that are linked to dm_customer with a FK.
My result is 1 result for customer, thats correct but account shows 12 results, where i expect 2 results
and Service point shows also 12 records where i expect 6 records.
There is no direct link between account and service point but both are linked to customer. Each customer can have 1 or 2 account And each customer can have 1 or many servicepoints.
Can you help me?

XML query structure problem

Hi experts,
I am looking for help on the following XML query. I have a table (example) organized as such:
meas data_element
ABC rate
DEF rate1
DEF rate2
DEF rate3
GHI rate
JKL rate1a
JKL rate2b I'm trying to keep the "meas" column as the top node attribute, with the "data_elements" as attributes of the children of "meas"
In short, I'm looking for the following output, but, well..keep coming up short.
<meas id="ABC">
 <data_elements>
 <data_element id="rate">
 <rpt>false</rpt>
 </data_element>
 </data_elements>
</meas>
<meas id="DEF">
 <data_elements>
 <data_element id="rate1">
 <rpt>false</rpt>
 </data_element>
 <data_element id="rate2">
 <rpt>false</rpt>
 </data_element>
 <data_element id="rate3">
 <rpt>false</rpt>
 </data_element>
 <data_elements>
</meas>
.....and so forth...I'm having trouble with getting the multiple rows of 'data_element' under 'data_elements', and under the single 'meas' one node, any suggestions? My code keeps generating multiple rows. The rpt node is a constant value of 'false'
Thanks

You have to group, and aggregate using XMLAgg :

SQL>
SQL> with sample_data (meas, data_element) as (
2 select 'ABC', 'rate' from dual union all
3 select 'DEF', 'rate1' from dual union all
4 select 'DEF', 'rate2' from dual union all
5 select 'DEF', 'rate3' from dual union all
6 select 'GHI', 'rate' from dual union all
7 select 'JKL', 'rate1a' from dual union all
8 select 'JKL', 'rate2b' from dual
9 )
10 select xmlserialize(content
11 xmlagg(
12 xmlelement("meas",
13 xmlattributes(meas as "id")
14 , xmlelement("data_elements",
15 xmlagg(
16 xmlelement("data_element",
17 xmlattributes(data_element as "id")
18 , xmlelement("rpt", 'false')
19 )
20 order by data_element -- if necessary
21 )
22 )
23 )
24 )
25 indent
26 ) as result
27 from sample_data
28 group by meas ;

Xcelsius with XMLA or XML Query Result Set

Hi Experts,
I want a direct connection from Xcelsius to my BW-Data. Because the new connection, coming with Fix Pack 2.1 is only avaiable for EHP 1 for NW 7.0 I tried to configure with XMLA and XML Query Result Set.
This Document tells the necessary steps: How to integrate Xcelsius 2008 with SAP NetWeaver BI without Integration Kit.pdf.
When I test my XML connection over http://<host>:<port>/TXmla/srvlet/TestXmla my Cubes will display.
So I do a Webservice-Connection with WSDL-URL. At Input-Values there are some entries like CUBE_NAME, CATALOG_NAME...
Output values arent avalible. How do I use these elements to show my Data in Xcelsius?
My Problem with the XML Query Result Set Connection is, that when I Log On to VC the following error appears:
You are not authorized to view the requested resource.
So I get the authorisationobjects: S_DEVELOP and S_RS_COMP as describe in 'How To... Resolve Visual Composer Issues'.
What values have I to enter by S_RS_COMP? And how can I enter my External Service in S_SERVICE. At the type WS the service isnt't avaiable.
Regards,
Jan

To use XMLA web service you need a wrapper function build to convert the XMLA output to the Xcelsius format. There are some documents available in SDN on how to do this.
You can use Live Office or Query as a Web service option to connect from Xcelsius to BW.
S_RS_COMP is the query ID which you are trying to access, S_SERVICE you can either give * or try to set up authorization log and see the expected value.

Error in testing XML query result set web service

Hi
I was trying to test a XML query result set web service in BW system with tcode wsadmin but getting error like
Cannot download WSDL from http://ibmbtsb02.megacenter.de.ibm.com:8070/sap/bw/xml/soap/queyview?sap-client=001&wsdl=1.1&mode=sap_wsdl: F:\usr\sap\W70\DVEBMGS70\j2ee\cluster\server0\apps\sap.com\com.sap.engine.services.webservices.tool\servlet_jsp\wsnavigator\root\WEB-INF\temp\ws1139464945296\wsdls\wsdlroot.wsdl (The system cannot find the path specified)
I had tried it first time few days ago and was able to test it successfully with the same configuration settings.
Could any one of you please provide any suggestion on this?

No method found for XML query element

Hi,
I have an EJB module which contains some entity beans.

This problem can be resolved by un-installing the IDE, removing my user directory, and re-installing the IDE (I am using SunOne Studio 5 SE Update 1). The problem is that it returns with alarming regularity.
Anyone else experiencing this? Any help would be much appreciated.

Sometimes, but not always, this exception appears in the ide.log before the error first occurs.

Use of Global Properties in URL path of XML Query

I am trying to use global properties to define the URL of XML query:
Globals.ImageFilePath&"SomePath/\File.xml"
but it does not like it. If I put the content of the Globals.ImageFilePath it works fine. What is the synatax for that?
I am using the XML query in a transaction within an image creation action block. When I try to define the URL parameter of the XML file as a link, it is not taken on account, and the image created has no data (it is empty). The URL is taken when defined on the Cofigure Object screen, but there I have the same problem to use the global variable parameter.
Any suggestions?
Thanks,
Vlad

Edited by: Vladimir Baltchev on Jul 29, 2008 11:40 PM

As I mentioned in my first posting, yes, I can put the global variable of the link editor for the URL parameter, it evaluates well, but it is not taken on account by the query, and the image generated is empty. Obviously there is a bug here, so I am trying to find a work around to use the global variable on the Configure Object screen, where the parameter URL is taken by the XML query, but on this screen I can not use the global variable. It works only if I put the content of the global variable.
So, does anybody know if we can use global variables on a Configure Object screen, or on the XML query URL field, and if so, what is the syntax to indicate global variable?
Thanks again,
Vlad

Cooresponding Lists Names/Values XML Query

Let's say there is an XML Schema that has
<element name="mt" minOccurs="0" maxOccurs="unbounded">
<element name="r" minOccurs="0" maxOccurs="unbounded">
And for each measurement type (mt), you have a cooresponding measurement value (r). There are additional elements between these two lists. The actual XML data would look similiar to
<mi>
 <mts>20061117100000-0800</mts>
 <gp>900</gp>
 <mt>MeasurementType1</mt>
 <mt>MeasurementType2</mt>
 <mt>MeasurementType3</mt>
 <mt>MeasurementType4</mt>
 <mt>MeasurementType5</mt>
 <mt>MeasurementType6</mt>
 <mt>MeasurementType7</mt>
 <mv>
 <moid>Identifier</moid>
 <r>58</r>
 <r>62</r>
 <r>43</r>
 <r>45</r>
 <r>43</r>
 <r>14</r>
 <r>29</r>
 <sf>FALSE</sf>
 </mv>
</mi>
The first occurance of mt corresponds to the first occurance of r, the second cooresponds to the second, et cetra.
The MI element can repeat hundreds of times and there can be many measurementTypes. Now, I'm trying to figure out how I can create an XML query to efficiently handle this. The problem is that the <r> value is within the complexType <mv> and that is on the same level as <mt>. The XML Query would cause a cartesian product if I were to use something like ...
select
extractValue(value(xmldata), '/mi/mts') measurement_time_stamp,
extractValue(value(xmldata), '/mi/gp') granularity_period,
extractValue(value(mt), '/mt') measurement_type,
extractValue(value(mv), '/mv/moid') measured_obj_id,
extractValue(value(r), '/r') measurement_value,
from xmltable
, TABLE(XMLSequence(Extract(value(xmltable), '/mi/mv'))) mv
, TABLE(XMLSequence(Extract(value(mi), '/mi/mt'))) mt
, TABLE(XMLSequence(Extract(value(mi), '/mv/r'))) r
This obviously wouldn't work. I could go and store all the types and values into a column using
select
replace(replace(replace(extract(value(mi), '/mi/mt').getStringVal(), '</mt><mt>', ';'), '<mt>'), '</mt>') measurement_type,
extractValue(value(mv), '/mv/moid') measured_obj_id,
replace(replace(replace(extract(value(mv), '/mv/r').getStringVal(), '</r><r>', ';'), '<r>'), '</r>') measurement_value
from xmltable
TABLE(XMLSequence(Extract(value(xmldata), '/md/mi'))) mi
, TABLE(XMLSequence(Extract(value(mi), '/mi/mv'))) mv
But this wouldn't work once the XML grew over 4000 bytes. So I need a way to extract this data maintaining the correct integrity (avoiding cartesians).
One idea is a pipelined table function but I have concerns about scalability with that method. Is there a way to accomplish this optimally? I have solutions for this but none of them is going to deliver the scalability I am seeking.
I expect the method chosen will probably need to handle a few hundred thousand files per day.
Thanks,

VJ
I'd not seen your XML schema when I worked the original example, so I reverse engineered it from the instance. Unfortunately when I work with your schema, which contains more levels of nested I can't get it to optimize properly

SQL>As you can see the re-write is not working out in this case. I'll ask development to take a look at it and see if they can solve it. I think it's similar to another bug I've filed...
WRT to your question about transforming. One easy transformation would be to number the nodes.. Eg use XSTL to add an index number to each MT node and each R node and then join on that value.

How to work on XML Query

Hi
Can someone please tell me how to work on XML Query. Mainly regarding what details to give for Source URL and Transform URL.
Thanks in Advance
Muzammil P.T

Hi Muzammil,
 XML query is used to get the xml documents in the server. One more thing is you can execute all queries and transactions built on xMII. For queries you need to use URL like http://<server name>/Lighthammer/Illuminator?QueryTemplate=<QT path>&Param.1=<value1>&Param.2=<Value 2>..
 Similar way you can execute the transactions as http://<server name>/Lighthammer/Runner?Transaction=<Transaction name with path>&InpueParameter=<value 1>&OutputParameter=<TrOutput>..
 The main advantage is you can execute any type of query and transaction. Dynamically you can change this values from the front end also..
 These all the things i know in XML, may be there are some other features are also avialable..
Thanks,
Rajesh.
PS : Please award points if the answer is useful.
