XPath query string returns zero node...

Hi,
I try to filling value of node's in "java embedding" activity, but i got Subj. error.
Text java code is :
setVariableData("MesAQ_Enqueue_Variable", "Soob", "/ns2:Soob/ns2:CtrlFraseAsProps/ns2:Field[2]/ns2:npp", "12345");
I know, node with index 2 not exist, but where i can add it, before set value ?
Thanks
Evgeniy

<from expression="ora:addChildNode(bpws:getVariableData("output", "payload", "/tns:bpelResponse/tns:results"), bpws:getVariableData('testResult'))"></from>
<to variable="output" part="payload" query="/tns:bpelResponse/tns:results"/>
</copy>
It adds the object testResult into the array results and then saves the updated array back into results.
There are tutorials on this that should either come installed with BPEL, or there are also ones on Oracle's site here, if you need to see more complete examples of array usage.

Human Workflow Task XPath query string returns multiple nodes.

I am looking for trouble shooting help for this error. I am no sure if it is a server or jdev issue.
I am running JDev version 10.1.3.3 and console version 10.1.3.1.0 locally.
General information on the BPEL process:
I have a temporary table in Oracle lite that I created items to be review by the user. I created a synchronous BPEL process. The first step in developing this process, I created the straight forward invoke the table to get the records, transform the records with a change the approve flag = "Y", and invoke the table to update the records. Works like a charm. I followed the online tutorial by dropping a human task after the transform, configured the parameters, setup the assignments, and moved the invoke to update table under the approved condition. If the table has only one record, the process runs great but if there are two records I get the following error message.
<selectionFailure xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"><part name="summary"><summary>XPath query string returns multiple nodes.

The error occurs in the first assign of the Human task after the assign copies the fields for the title. I underlined line number 178.

Thank you for any help you can give me.

Here is how I solved this problem: I was told by the metalink folks that I should use the same verion of SOA console as jdev. So I went back to jdev 10.1.3.1. Rather than reading from the Oracle lite table, I dumped the table into a flat file. I read flat file and populated the workflow. Remember to set the 'messages in batch' flag in the file adapter to 1 and the number of records to skip to zero in the format builder for the flat file. The process now reads each record and creates an instance for that each record. In other words, if I have 8 records in my flat file, I will have 8 instances of the process running on the console. Thanks Jeremy for your help figuring this out.

Any pointers on this?

Hi-
This is because you are have multiple nodes either in source or target XML.
My guess is some nodes of your XML might be repeating (means a single element/node has multiple values). Can you please check that or please post your XML here.

Xpath Query to find parent nodes

My XMl is like this
<UserAgent1>
<Name>QTS </Name>
<NetworkFamily>GSM</NetworkFamily>
<NetworkSupportedMap>0x06</NetworkSupportedMap>
</UserAgent1>
<UserAgent2>
<Name>QuickTime</Name>
<NetworkFamily>GSM</NetworkFamily>
<NetworkSupportedMap>0x06</NetworkSupportedMap>
</UserAgent2>
Now if they give a search String like "GSM" without specifying any tag
Then i use the xpath query
//*[contains(text(),'GSM')]
This will give me the child element <NetworkFamily>GSM</NetworkFamily> . .and with this i will find out the parent element which is <UserAgent1> & <UserAgent2>
IS there any query which will give me directly the Parent Nodes whose childnodes contain the given text ?

Well, of course there is. But I couldn't remember how so I googled the keywords "xpath parent". The first link that came back suggested
//*[contains(text(),'GSM')]/..
and the second suggested the parent axis
parent::(//*[contains(text(),'GSM')]) or maybe //parent::*[contains(text(),'GSM')]
So yes, there's several ways. And they were easy to find with Google too.

XPath query error - xml extension in schema

Hi,
I am getting following error when i try to assign values to input xml payload before
invoke process.
"{http://schemas.xmlsoap.org/ws/2003/03/business-process/}selectionFailure" has been thrown.
<selectionFailure>
<part name="summary" >
<summary>XPath query string returns multiple nodes. According to BPEL4WS spec 1.1 section 14.3, The assign activity part and query /child::parameter/child::param1 should not return multipe nodes. Please check the BPEL source at line number "40" and verify the part and xpath query /child::parameter/child::param1. </summary>
</part>
</selectionFailure>
The generated XPath resolves to a single node only (tested using XMLSpy). The only reason i can think of is that the xml schema in wsdl is extending a base xml type to a new type.
It works fine if the extending xml type is merged with it's base type, and used as one single complex type.

reg,

I am also having the xml extension issue and since we are dealing with large WSDL files (exceed 40,000 lines) it would be ridiculous to move all extension classes to the base type (parent class). Has this bugged been looked at and when can it be resolved since it seems to be a major issue in JDeveloper.

XPath - Return current node without child nodes

Good day.
I hv the following XML for example and I tried to write a XPath query to return just the <AAA> and omit all the other child nodes (BBB and CCC and BBBBB) .
<AAA Name='aaa' ID='aaa'>
<BBB>bbbbbbbbbb</BBB>
<BBBBB>bbbbbbbbbbbbbbb</BBBBB>
<CCC>cccccccccc</CCC>
</AAA>I tried //AAA/self::* but it still return the whole childnodes to me. I searched in internet as well but I didn't found any solution for that. May be I was using the wrong keywords to search.
Any idea how to accomplish this ?
Thanks.
SonicWave

XPath will only return nodes that already exist in the document. What you are asking for is another node that is constructed from that AAA node by removing all its children. I don't know how you would do that, because I don't know anything about the structures you are using (DOM? XSLT? What?). But XPath can't do it.

Jsp:forward param not getting included in my query string

Hi,
On a particular JSP page, mine.jsp, I am forwarding to a servlet ...
<jsp:useBean id="HotelResortDBBean" class="com.lvcva.database.HotelResortDBBean" scope="request" />
<jsp:forward page="/meetings/meeting-venues/results">
<jsp:param name="sqftRange" value="${empty param.meetingsqft ? -1 : param.meetingsqft}" />
</jsp:forward>This forwards to a servlet, when I query "request.getQueryString", it comes up null. However, when I enter the URL, "mine.jsp?sqftRange=-1", the query string returns "sqftRange=-1" as expected. Can someone tell me what I'm doing wrong in the above that is causing the jsp:param to not be added to the query string?
- Dave

a forward does not create a new request, and thus the query string is not altered. If you want the query string to change, use a redirect in stead.
note: even though the query string does not change, the new parameter IS added to the HttpServletRequest object, so you can still fetch the new parameter from it even with the forward.

Retrieve xml attribute value of nth xml node using xpath query

I have an xml with following stucture...
<xml>
<header>
<DocumentReference OrderId="order001">
<DocumentReference OrderId="order002">
<DocumentReference OrderId="order003">
I have to loop through this xml and retrieve the orderId values inside Biztalk orchestration.
In the expression shape, I get the count of 'DocumentReference' nodes using an xpath query and then
Added a loopshape to make sure it loops thru all nodes
Loop condition:   n<=nodeCount     (where n is an integer variable, n=0 to begin with, incremented by 1 thru each loop, nodeCount is # of DocumentReference nodes)
I try retrieve to the orderId in the following expression shape using the below xpath query
xpathQuery = System.String.Format("//*[local-name()='OrderReference'][{0}]/@orderID)",n);
sOrderId = xpath(MsgSingleInvoice,xpathQuery);
And I get the following exception:
Inner exception: '//*[local-name()='OrderReference'][1]/@orderID)' has an invalid token.
Exception type: XPathException
Appreciate any help!   thanks!

Thanks for the quick response. I got rid of it.
And I see a different error:
Inner exception: Specified cast is not valid. Exception type: InvalidCastException
Source: Microsoft.XLANGs.Engine
Target Site: System.Object XPathLoad(Microsoft.XLANGs.Core.Part, System.String, System.Type)
Since variable 'n' is of integer type, I suspected it and changed it to n.ToString() and tested again and still see the same error.

Query to return ALL rows even those with zero counts

Hi,
The following query will return only those rows that have a non zero count value:
select c.id, a.name, count(*) as XYZ from CON c, CUST a
where c.help !='1' and (c.id = a.id) group by c.id, a.name order by c.id;
The results are:
1 ME 3
3 YOU 4
What i want is to return all rows in CUST and the count, XYZ, that correspond to each row in CUST that matches the whare condition above, even if the count is zero.
ie
1 ME 3
2 WE 0
3 YOU 4
Can this be done?

You may want to get the counts then do the outer join. If you simply count with an outer join you will get 1 for 'WE' because there is a row in the cust table with 'WE'. This may work for you;
with
cust as (
   select 1 id, 'ME' name from dual union all
   select 2 id, 'YOU' name from dual union all
   select 3 id, 'WE' name from dual),
con as (
   select 1 id, '2' help from dual union all
   select 1 id, '2' help from dual union all
   select 1 id, '2' help from dual union all
   select 2 id, '2' help from dual union all
   select 2 id, '2' help from dual union all
   select 2 id, '2' help from dual union all
   select 2 id, '2' help from dual)
-- end of test data
select a.id, a.name, nvl(c.cnt,0) xyz
from cust a,
   (select id, help, count(*) cnt
   from con
   where help !='1'
   group by id, help) c
where a.id = c.id(+)

Query returns zero records in coldfusion context, but works fine in Navicat

I've got a query that's returning zero records when I load a page. If I copy and paste that same query (from the debug output) into navicat, I get rows returned (as I expect). Has anyone seen this? It happens locally (CF9) AND remotely on our staging server (CF10). Even weirder, it's a query that was previously working fine - I simply added an if statement to the where clause, and all of a sudden...
Here's the query:
        <CFQUERY name="LOCAL.getEncounterServices" datasource="#REQUEST.dsn#">
        SELECT
            a.EncounterProductID,
            a.DateTime AS ServiceDate,
            aa.CartItemID,
            aaa.CartID,
            aaaaa.CartStatus,
            b.ProductID,
            b.ProductName,
            b.CPTCode,
            b.Price,
            c.EncounterID,
            c.DateTimeClosed AS EncounterClosedDate,
            d.FirstName,
            d.LastName
        FROM
            EncounterProducts a
                LEFT JOIN CartItemProduct aa ON (a.EncounterProductID = aa.EncounterProductID AND aa.Active = 1)
                LEFT JOIN CartItem aaa ON (aa.CartItemID = aaa.CartItemID)
                LEFT JOIN Cart aaaa ON (aaa.CartID = aaaa.CartID)
                LEFT JOIN CartStatus aaaaa ON (aaaa.CartStatusID = aaaaa.CartStatusID),
            Product b,
            Encounters c,
            Contacts d,
            EncounterStatuses e
        WHERE
            1 = 1
            AND (aa.CartItemID IS NULL OR aaaaa.CartStatus = 'Deleted')
            AND a.Active = 1
            AND a.ProductID = b.ProductID
            AND a.EncounterID = c.EncounterID
            AND c.PatientID = d.ContactID
            AND c.EncounterStatusID = e.EncounterStatusID
            AND e.EncounterStatus = 'Closed'
          <CFIF IsDefined("ARGUMENTS.encounter") AND IsObject(ARGUMENTS.encounter)>
                 AND c.EncounterID = <CFQUERYPARAM cfsqltype="cf_sql_integer" value="#ARGUMENTS.encounter.getID()#">
         <CFELSE>
                AND c.DateTimeClosed >= <CFQUERYPARAM cfsqltype="cf_sql_date" value="#ARGUMENTS.startDate#">
                AND c.DateTimeClosed < <CFQUERYPARAM cfsqltype="cf_sql_date" value="#DateFormat(DateAdd('d', 1, ARGUMENTS.endDate), 'yyyy-mm-dd')# 00:00:00">
           </CFIF>
            AND c.LocationID = <CFQUERYPARAM cfsqltype="cf_sql_integer" value="#ARGUMENTS.locationID#">
            AND c.CustomerID = <CFQUERYPARAM cfsqltype="cf_sql_integer" value="#ARGUMENTS.customerID#">
        </CFQUERY>
All of this worked just fine before I added the lines:
         <CFIF IsDefined("ARGUMENTS.encounter") AND IsObject(ARGUMENTS.encounter)>
                 AND c.EncounterID = <CFQUERYPARAM cfsqltype="cf_sql_integer" value="#ARGUMENTS.encounter.getID()#">
         <CFELSE>
                AND c.DateTimeClosed >= <CFQUERYPARAM cfsqltype="cf_sql_date" value="#ARGUMENTS.startDate#">
                AND c.DateTimeClosed < <CFQUERYPARAM cfsqltype="cf_sql_date" value="#DateFormat(DateAdd('d', 1, ARGUMENTS.endDate), 'yyyy-mm-dd')# 00:00:00">
          </CFIF>
Previously, it had just been:
                AND c.DateTimeClosed >= <CFQUERYPARAM cfsqltype="cf_sql_date" value="#ARGUMENTS.startDate#">
                AND c.DateTimeClosed < <CFQUERYPARAM cfsqltype="cf_sql_date" value="#DateFormat(DateAdd('d', 1, ARGUMENTS.endDate), 'yyyy-mm-dd')# 00:00:00">
With no IF/ELSE statement.
Anyone seen anything like this before? Any ideas?

Right, I'll start disabusing myself of the DateFormat!

Maximum length of query string for functions return a SELECT

Hi all,
I have a report that gets it's SELECT statement from a function, instead of being coded into the region. All was well but I suspect now I'm blowing some kind of limit as I'm getting an error :
ORA-06502: PL/SQL: numeric or value error
Error ERR-1101 Unable to process function body returning query.
However if I run the procedure out of ApEx and grab the SELECT statement then it works fine. The length of the query is 8636 bytes (yup, it's a beauty!).
Does anyone know if there is a hard limit to the size of the string that can be returned?
I'm using ApEx 3.1.
Thanks,
Steve H

I do have a similar painfull scenario - Although my query length is very less i.e 618 bytes only.
I have defined a stored function, which returns an SQL query string, this return SQL string executes fantastic but when I tried to to call this function from a APEX report it gives error. the details are as follows. Please help.......
The function code:
CREATE OR REPLACE function PROD."TEST_C_QRY"
return VARCHAR2
is
msql VARCHAR2(32767);
Begin
msql:='Select null,statusname,AgeInd, ';
For m_stat in (select statusname from a02_status)
loop
msql:= msql || q'[decode(statusname,']';
msql:= msql || m_stat.statusname;
msql:= msql || q'[',count(id),0) ]';
msql:= msql || m_stat.statusname|| ',';
end loop;
msql:=rtrim(msql,',');
msql:= msql||' from ';
msql:= msql||'( ';
msql:= msql||'select a.id, round(sysdate-a.registeredon) TimeSpan,';
msql:= msql||'case ';
msql:= msql||q'[when round(sysdate-a.registeredon)<=7 then 'Week' ]';
msql:= msql||q'[when round(sysdate-a.registeredon)>7 and round(sysdate-a.registeredon)<14 then 'Fortnight' ]';
msql:= msql||q'[when round(sysdate-a.registeredon)>14 and round(sysdate-a.registeredon)<30 then 'Month' ]';
msql:= msql||q'[else 'More...' end ageind,]';
msql:= msql||'a.status_id,b.statusname ';
msql:= msql||'from a02_task a,a02_status b ';
msql:= msql||'where b.id=a.status_id) ';
msql:= msql||'group by statusname,AgeInd;';
return msql;
end TEST_C_QRY;
The Output SQL comes from this is
SQL> Select null,statusname,AgeInd, decode(statusname,'Scheduled',count(id),0) Scheduled,decode(statusname,'Executing',count(id),0) Executing,decode(statusname,
'Completed',count(id),0) Completed from ( select a.id, round(sysdate-a.registeredon) TimeSpan, case when round(sysdate-a.registeredon)<=7 then 'Week' when round
(sysdate-a.registeredon)>7 and round(sysdate-a.registeredon)<14 then 'Fortnight' when round(sysdate-a.registeredon)>14 and round(sysdate-a.registeredon)<30 then
'Month' else 'More...' end ageind, a.status_id,b.statusname from a02_task a,a02_status b where b.id=a.status_id) group by statusname,AgeInd;
The result that comes when I execute the above resultant SQL is as follows.
N STATUSNAME AGEIND SCHEDULED EXECUTING COMPLETED
Completed More... 0 0 4
Completed Week 0 0 1
Scheduled Week 1 0 0
Completed Month 0 0 3
Executing More... 0 1 0
Executing Month 0 6 0
Scheduled More... 1 0 0
7 rows selected.
But the surprising error that comes from Oracle XE when I use the following code for stacked bar chart
Code:
begin
return TEST_D_QRY;
end;
Error thrown by XE report builder is as follows:
1 error has occurred
Failed to parse SQL query!
Select null,statusname,AgeInd, decode(statusname,'Scheduled',count(id),0) Scheduled,decode(statusname,'Executing',count(id),0) Executing,decode(statusname,'Completed',count(id),0) Completed from ( select a.id, round(sysdate-a.registeredon) TimeSpan, case when round(sysdate-a.registeredon)<=7 then 'Week' when round(sysdate-a.registeredon)>7 and round(sysdate-a.registeredon)<14 then 'Fortnight' when round(sysdate-a.registeredon)>14 and round(sysdate-a.registeredon)<30 then 'Month' else 'More...' end ageind, a.status_id,b.statusname from a02_task a,a02_status b where b.id=a.status_id) group by statusname,AgeInd;
Certain queries can only be executed when running your application, if your query appears syntactically correct, you can save your query without validation (see options below query source).

Oracle Service Bus-Outbound-Query String node

Hi,
i have created a proxy service and did all the message flows,the problem is that i cant see the outboud query string node. Is there any way to create the node and then assign values to it.

There is this $header variable which you should populate before calling the BS. What is the type of BS? If it is WSDL BS , Any Soap BS then above solution will work. I assume that yours is WSDL based BS and setting $header should resolve this issue.
AnyXML and Messaging type BS services requires that you create proper pay load (setting $header will not work).
There is also other actions Set Transport Headers {outbound request/inbound response} which can be used to set transport related headers but not soap headers.

Xpath query return problem

Hi;
I want to load xml file into the database oracle 9.0.2 using Oracle XML DB Utilities Package on "http://otn.oracle.com/sample_code/tech/xml/xmldb/xdbutilities/XMLDB_Utilities_Overview.htm"
I have a schema like:
<xs:element name="catalog">
<xs:element name="catalog">
<xs:complexType xdb:SQLType="OBJ_CATALOG">
<xs:sequence>
<xs:element name="category">
<xs:complexType xdb:SQLType="OBJ_CATEGORY">
<xs:sequence>
<xs:element name="product">
<xs:complexType xdb:SQLType="OBJ_PRODUCT">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
and my file include:
[i]<catalog>
<category name="books">
<product id="1" keywords="yasanti, Latin Amerika" >
<name>Gunes Topraklari</name>
</product>
</category>
<category name="CDs" >
<product id="5" keywords="music, easy listening" >
</product>
</category>
I can use xpath query like
select extract(value(x), '/catalog/category[@name="books"]').getstringval() from product_table x
and get result but I can not take any data about product elements with queries such that
select extract(value(x), '/catalog/category[@name="books"]//name/text()').getstringval() from product_table x
Does anyone has an idea about this problem?
Thanks a lot.
Alper.

Contains return all the records when the query string matches the columns

I used the multi_column_datastore preference and created an index on three columns (item_name, description,owner_part_number). Now if I do a search:
select * from items where contains(description, 'description') > 0;It returns all the rows in items table, but not all the rows have "description" as a word. I guess Oracle text assumes the query intends to get all the rows as the query string matches one of the column names. My question is whether Oracle Text has any preference settings to alter this behavior?
execute ctx_ddl.create_preference('item_multi_preference', 'MULTI_COLUMN_DATASTORE');
execute ctx_ddl.set_attribute('item_multi_preference', 'columns', 'item_name, description,owner_part_number');
create index item_text_index on items(description) indextype is ctxsys.context filter by owner parameters('LEXER ENG_LEXER WORDLIST ENG_WORDLIST STOPLIST CTXSYS.EMPTY_STOPLIST datastore item_multi_preference MEMORY 1024M');Thanks.

It looks like a basic_section_group fixes the problem as well, as demonstrated below and I believe a basic_section_group may be more efficient than auto_section_group.
