"CONNECT BY"-like query using XPath

Greetings!
The problem is as follows:
I have a XML document whose main part contains a set of many subelements names "rasterFile". Each of this elements has an attribute "rasterRefId" which refers to another rasterFile element (to its id attribute). These references form a tree-like structure of parent and child rasters.
What we need is to be able to effectively extract a subset of this structure, e.g. for rasterFile with id="4" we need to get this element, its referenced elements, and the elements referenced by the previously referenced elements (but we may request event four or five levels).
Using a relation database, we should use the CONNECT BY statement, but the document is stored in a XMLType table containing only one row (we use only one large document). So I need to do this sort of query in XPath. How? Or is there any other way to do that?
Thanks in advance.
Petr
The sample document (shortened, the original has about ten thousand rasterFile elements):

Thanks for reply.
Well, the view doesn't seem to help me. We have only one xml document stored and therefore there is only one row in the XMLType table. Using the "SELECT extract()" statement returns one row containing whole result (in CLOB or whatever) and the view has the same problem.
What would solve this problem is the query for a collection of elements that would return each resulting element in a single row. But I haven't been able to find out how to do such a thing.

Cost of query, using Xpath

Hi,
I have a query:
SELECT distinct EXTRACTVALUE (VALUE(M), '/MedlineCitation/MedlineID') AS MEDLINE_ID,
extractValue(value(s),'/QualifierName') AS QUALIFIER,
extractValue(value(t),'/DescriptorName') AS MESH_HEADING,
extractValue(value(t),'/DescriptorName/@MajorTopicYN') AS MAJOR
FROM MEDLINECITATIONS M,
TABLE ( xmlsequence (
extract(value(M),
'MedlineCitation/MeshHeadingList/MeshHeading/DescriptorName'))) t,
TABLE ( xmlsequence (
extract(value(M),
'MedlineCitation/MeshHeadingList/MeshHeading/QualifierName'))) s
COST ALL ROWS (optimizer: CHOOSE), total cost: 52,222,538,544
Is there a way to optimize this query. I'm working with 100,000 of rows and it's very slow.

Maxim
How many collections (nodes that can occur more than once) are there in the schema..
You might want to try the following:
In XMLSPY, Under the DTD / Schema menu, select enable Oralce Schema Extensions and then select Oracle Schema Options, storeVarrayAsTable
Under the root element add the annotation xdb:defaultTable="YOURTABLENAME"
Drop and re-register the schema. Let XMLDB create 'YOURTABLENAME' for you as part of the registrations process
Now try the query
select table_name from user_nested_tables where table_name = 'YOURTABLENAME'.
This will tell us whether the default approach of storing all collections as nested tables is too general for your schema.
What we are trying to do here is ensure that the collections we want to query are stored as seperate rows in a nested table rather than as a VARRAY of objects stored in a LOB..

Executing Like Query

Hey Can Anyone tell me how ca i execute like query using jdbc odbc bridge
when i use the following syntax it gives me an error
select topicid,name,subject from topic where subject like("subject1%")
or
select topicid,name,subject from topic where subject like("subject1*")
both of the statements issue an error
Please Help
asap
Thanx

when i use the following syntax it gives me an error
select topicid,name,subject from topic where subject
like("subject1%")You need to use single quotes instead of double quotes.
SELECT topicid, name, subject FROM topic WHERE subject LIKE 'subject1%'

Powershell use Connection String to query Database and write to Excel

Right now I have a powershell script that uses ODBC to query SQL Server 2008 / 2012 database and write to EXCEL
$excel = New-Object -Com Excel.Application
$excel.Visible = $True
$wb = $Excel.Workbooks.Add()
$ws = $wb.Worksheets.Item(1)
$ws.name = "GUP Download Activity"
$qt = $ws.QueryTables.Add("ODBC;DSN=$DSN;UID=$username;PWD=$password", $ws.Range("A1"), $SQL_Statement)
if ($qt.Refresh()){
$ws.Activate()
$ws.Select()
$excel.Rows.Item(1).HorizontalAlignment = $xlCenter
$excel.Rows.Item(1).VerticalAlignment = $xlTop
$excel.Rows.Item("1:1").Font.Name = "Calibri"
$excel.Rows.Item("1:1").Font.Size = 11
$excel.Rows.Item("1:1").Font.Bold = $true
$filename = "D:\Script\Reports\Status_$a.xlsx"
if (test-path $filename ) { rm $filename }
$wb.SaveAs($filename, $xlOpenXMLWorkbook) #save as an XML Workbook (xslx)
$wb.Saved = $True #flag it as being saved
$wb.Close() #close the document
$Excel.Quit() #and the instance of Excel
$wb = $Null #set all variables that point to Excel objects to null
$ws = $Null #makes sure Excel deflates
$Excel=$Null #let the air out
I would like to use connection string to query the database and write results to EXCEL, i.e.
$SQL_Statement = "SELECT ..."
$conn = New-Object System.Data.SqlClient.SqlConnection
$conn.ConnectionString = "Server=10.10.10.10;Initial Catalog=mydatabase;User Id=$username;Password=$password;"
$conn.Open()
$cmd = New-Object System.Data.SqlClient.SqlCommand($SQL_Statement,$conn)
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output += ,@($rdr.GetValue(0), $rdr.GetValue(1))
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
How would I read the columns and data for $sql_output into an EXCEL worksheet. Where do I find these tutorials?

Hi Q.P.Waverly,
If you mean to export the data in $sql_output to excel document, please try to format the output with psobject:
$sql_output=@()
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output+=New-Object PSObject -Property @{data1 = $rdr.GetValue(0);data2 =$rdr.GetValue(1)}
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
Then please try to use the cmdlet "Export-Csv" to export the data to excel like:
$sql_output | Export-Csv d:\data.csv
Or you can export to worksheet like:
$excel = New-Object -ComObject Excel.Application
$excel.Visible = $true
$workbook = $excel.Workbooks.Add()
$sheet = $workbook.ActiveSheet
$counter = 0
$sql_output | ForEach-Object {
$counter++
$sheet.cells.Item($counter,1) = $_.data1$sheet.cells.Item($counter,2) = $_.data2}
Refer to:
PowerShell and Excel: Fast, Safe, and Reliable
If there is anything else regarding this issue, please feel free to post back.

Xpath query using ANE with AIR3.9 for iOS app

we are building an app for iOS using AIR 3.9 where we have to load and parse the xml document so that we can read the images path and download the stuff on iOS device. To fix this issue we have found a solution using XCode via ANE where by using XPath Query classes such as "PerformXPathQuery", "PerformXMLXPathQuery", "xmlReadMemory" etc. The code is running well when build on simulator itself on mac machine. But when we are packaging the ANE with AIR 3.9, it gives us the error which says that:-
Error occurred while packaging the application:
Undefined symbols for architecture armv7:
"_xmlReadMemory", referenced from:
      _PerformXMLXPathQuery in libnet.example.download.a(ExampleLib.o)
ld: symbol(s) not found for architecture armv7
Compilation failed while executing : ld64
I have tried linking binary with libraries like "libxml2.dylib", "libxml2.2.dylib" and libz.dylib + added the libXML header files to the header search path in the build properties, but got no help.
our AIR 3.9 platform xml looks like:-
<platform xmlns="http://ns.adobe.com/air/extension/3.9">
    <sdkVersion>4.0.0</sdkVersion>
    <linkerOptions>
        <option>-ios_version_min 4.2</option>
        <option>-framework UIKit</option>
        <option>-framework Foundation</option>
        <option>-framework CoreText</option>
    </linkerOptions>
</platform>
can anyone suggest where we are going wrong!
thanks in advance

Found the solution, i was missing the framework related to xPath library in platform.xml

Dataset query issues twice if the dataset is connected to matrix and used in multilookup function

hello everybody.
could not find any information if this is an intended behavior:

Hello, Wendy.
I prepared a very empty sample report for you to demonstrate the problem - with this report, i hope, there is no place to discuss the shrinking of time data retrieval.
There is one dataset, one parameter and one lookup function. The query is executed twice.

No. Your iMac only has DVI video connection. You would need an iMac with Thunderbolt.

Copying Variables in BPEL using XPath Query

Hi,
I am new to BPEL and i want to know if it is possible to copy data from one variable to another using XPath Query in the <from> <to> tags, when the two variables are of different message types.
I am trying to create a sample BPEL that would receive a String through the receive tag tied to one partner link (WSDl) and then invoke a different webservice using the <invoke> tag tied to another partner link (WSDL) by passing the received variable.
I have pasted the BPEL File and the two WSDl files involved.
My Issue is that when I send a soap request to the BPEL, it is passed as null to the webservice invoked.
Probably because the copy tags don't work.
Please help.

Hi,
Yes, it very much is possible.
Xpath query provides a lot many data type conversion functions(string to int, string to date etc), which can be used in copying variables.
thanks

Looking for a keyword using like query which could contain multiple occurrence in the same column

I am facing an issue. A bunch of my frontend JSP code has been stored in few tables of my database (65 rows in a table), which I have identified using few like queries. Now I want to update a Href link which is present in all these queries. But since these column entries are very long (50-60 lines long) and it is possible that a few rows may the link (which is to be replaced), multiple times, I am not sure that if a simple update query using a single like will work for it or not?
Any suggestion/ideas are welcome.
Please let me know if you require any more info.

Yes; whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), so that the people who want to help you can re-create the problem and test their ideas.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Simplify the problem as much as possible. For example, if your strings are sometimes up to 4000 characters long, you don't have to post any data that's nearly that long. You can probably show what you want with strings that are 80 characters long.
Always say which version of Oracle you're using (for example, 11.2.0.2.0).
See the forum FAQ: https://forums.oracle.com/message/9362002#9362002
This statement:
UPDATE table_x
SET str = REPLACE ( str
                   , old_link
                   , new_link
WHERE   str LIKE '%' || old_link || '%'
will change all occurrences of old_link to new_link. It will only change the rows where old_link occurs, but, aside from that, it doesn't matter how many times old_link occurs in str: if it appears 2 times in the same str, then both occurrences will be changed to new_link.
Watch out for the "mother is in chemotherapy" problem. If old_link is 'bar.com', the statement above will change 'fubar.com'. You may need REGEXP_REPLACE and/or REGEXP_LIKE if you need to consider what (if anything) comes immediately before 'bar.com' when deciding whether or not to change it.

IPhone 5 unable to connect to internet or use web-based apps like Facebook or Tumblr

About two days ago, shortly after using my iPhone 5 to upload a picture of my son eating a donut to Facebook, I seem to have lost all ability to connect to the internet or update content on web-based apps like Facebook or Tumblr. I tried to restore my iPhone in iTunes on my computer but could not do that without first turning of "Find My iPhone," in the iCloud section of my settings. When asked to enter my password to turn off this feature the phone is "unable to connect to iCloud." It doesn't seem to matter if I'm connected to WiFi or using my cell data - I'm getting a strong signal in either case, but the phone is unable to connect to anything. I CAN make phone calls and send texts but that's just about it.
I recently updated to IOS 8.1.1 but it worked fine for several days before this problem started. Any ideas?

I reset my network settings (Settings > General > Reset > Reset Network Settings) and rejoined my network, and that seemed to fix it. Apps are working on wifi and on data, and I can once again send imessages. Since I couldn't find a similar post very easily, I wanted to post this for whoever needs help with this problem ;D

Our business would like to use or connect to an other online payment gateway on Business Catalyst.

Dear Manger,
Our business would like to use or connect to an other online payment gateway on Business Catalyst, That's the KCP (www.KCP.co.kr) serviced in South Korea.
We have registered already at KCP. Can we use or connect the payment gateway service on Bc? I think, a technical issue is not the problem.
Of course, a business target of the global online shop is Asia including South Korea. So we need the global & domestic payment gateway. Our headquarter is in Korea, Republic of. (South Korea).
Is it something problem for using the payment gateway service?
And If we get possible, how long take the installation period?
Your reply is much awaited.
All the best of success.
Sincerely,
William NAM

I don't believe that is a supported gateway with BC.
Talk to these guys: Two Blokes With A Postie - They can help you integrate a third party gateway with BC using the API.

How to use Xpath to query elements loaded from different xml docs?

I have a big DBLP XML doc (95mb), to load into the container, i splitted the doc into many small xml docs by the publication types, such as articles, books, inproceedings, etc.
I tried to use xpath query such as
query 'collection()/dblp[article/author]/book[title]'
I got empty answers.
but if i use XQuery such as
query 'let $r:=collection()/dblp,$a :=$r/inproceedings/author
for $l2 in $r/book
where $a and $l2/title
return <result> {$l2}{$a}</result>'
i got answers. However, if i remove {$a} from the return clause, i still got empty answers.
is there any problem with my Xpath query and flwor Xquery?

xiaoying

Hi John,
Following is the procedure i have used to load the xml docs (after the indexes have been created):
private static void loadXmlFiles(File path2DbEnv,String theContainer, File file) throws Throwable {
     //Open a container in the db environment
          XmlManager theMgr = null;
          XmlContainer openedContainer = null;
          myDbEnv env;
          try {
          env = new myDbEnv(path2DbEnv);
     theMgr = new XmlManager(env.getEnvironment(), new XmlManagerConfig());
     //use node container
     theMgr.setDefaultContainerType(XmlContainer.NodeContainer);
               try{
               openedContainer = theMgr.createContainer(theContainer);
               }catch (XmlException e){
                    //if the container alreay exist, then open it;
                    openedContainer = theMgr.openContainer(theContainer);
          //Get an update context.
          XmlUpdateContext updateContext = theMgr.createUpdateContext();
               String theFile = file.toString();
               String docName=file.getName();
          //Get the input stream.
          XmlInputStream theStream = theMgr.createLocalFileInputStream(theFile);
          System.out.println("Adding " + theFile + " to container " +
                         theContainer);
     //     Do the actual put
          openedContainer.putDocument(docName, // The document's name
          theStream, // The actual document.
          updateContext, // The update context
     //     (required).
          null); // XmlDocumentConfig object
          System.out.println("done.");
          //XmlException extends DatabaseException, which in turn extends Exception.
          // Catching Exception catches them all.
          } catch (XmlException e){
               System.err.println("Error loading files into container " + theContainer);
               System.err.println(" Message: " + e.getMessage());
               //In the event of an error, we abort the operation
               // The database is left in the same state as it was in before
               // we started this operation.
               throw e;
          finally {
          cleanup(theMgr, openedContainer);
Unfortunately, i waited for around 20 hours 148mb doc was not loaded; so i gave up.
Could you please give me some suggestions on how to load the large doc efficiently ? thanks.

xiaoying

Why does my airport utility always ask me to connect an ethernet cable when I would like to use the extended network option?

Why does my airport utility always ask me to connect an ethernet cable when I would like to use the extended network option?

Please locate the model number on the side of the AirPort Express. Hard to see.....gray lettering on a white background....so you may likely need a magnifying glass and good lighting to see it.
The model number starts with a "A" followed by four numbers. If you see A1084 or A1088, unfortunately AirPort Utility 6.x in Mavericks OS X (10.9.4) does not support these older models. However, you can still administer these models if you have a Mac.....or can borrow one for a few minutes....using Leopard (10.5.x) or Snow Leopard (10.6.x), or a PC with AirPort Utility installed on the device.
