XPath query against XMLType

Hello,
I am trying to reproduce the following XPath query using XDB functionality against a XMLType column:
//AtomicPart[@MyID='190' or @MyID='495' or @MyID='1662']
If I do the following I do get all AtomicParts:
select X.xml.extract('//AtomicPart') FROM TEST X
But I havent figured out how to do the or operation. Is it possible or does it require views?
Thank you,
Robert

Why Is Query Against XMLTYPE Table ACME_CUST Doing A Full Table Scan?

On our Oracle Database 11g Enterprise Edition Release 11.2.0.1.0, we have a query against against a 25,214 record XMLTYPE ACME_CUST table.

Hi Richard,
The 10053 event appears overkill for this situation. What's the big deal?
Set the event, run the query, unset the event, check the trace file, that's all.
It's not overkill if it helps you understanding what happens and why an index is of no use in this situation.
Tried the /*+ INDEX_FFS(ACME_CUST_ID_PK) */ hint in the 'nested' query.Not sure what nested query you're referring to, so if I misunderstood what you mean, just ignore the following comment.
From what you posted earlier, it looks like you're talking about this part :
listagg(ac.acme_cust_id,'|') WITHIN GROUP (
ORDER BY ac.acme_cust_id,ac.acme_cust_id) CUST_IDThat's not a nested query, it's a projection. All the main work (retrieving rows) has already been done when it comes to this part.
May just have to accept the query performance as it is...Maybe you can try something else.
See the document : Oracle XML DB : Best Practices, page 15 ex. 8 :
When there are multiple scalar values that need to be grouped or ordered, it is better to write it
with XMLTable construct that projects out all columns to be ordered or grouped as shown
below.Here's an example close to your actual requirement :

Query against XMLType

I'm hung up on something that I suspect is very easy, but I have little experience working with XML in the database and think I've just stared at it too long.
I have an XML document (fragment below) stored as an XMLType in a 10g R2 database table and I want to return the following result set from a query against the document:
PAGE_ID PAGE_SUBMISSION_FIELD
21 F39EF21
21 F85FG3E
21 F73EF58
21 FA4939F
22 FDE77A4
22 FF3AD33
Here is a fragment of the XML document:
<root-interface>
<page-group>
<display-page validation-state="new">
<id>21</id>
<page-submission-fields>
<page-submission-field>F39EF21</page-submission-field>
<page-submission-field>F85FG3E</page-submission-field>
<page-submission-field>F73EF58</page-submission-field>
<page-submission-field>FA4939F</page-submission-field>
</page-submission-fields>
</display-page>
<display-page validation-state="new">
<id>22</id>
<page-submission-fields>
<page-submission-field>FDE77A4</page-submission-field>
<page-submission-field>FF3AD33</page-submission-field>
</page-submission-fields>
</display-page>
</page-group>
</root-interface>
Here is the table in which it is stored:
desc cms_session_interfaces
Name Null? Type
SESSION_ID NOT NULL NUMBER
INTERFACE_ID NOT NULL NUMBER
CREATED NOT NULL DATE
LAST_ACCESSED DATE
INTERFACE_XML SYS.XMLTYPE
Here is a close as I've come with a query:
select extract(value(display_pages), '//id/text()').getStringVal() page_id,
extract(value(display_pages), '//page-submission-fields/page-submission-field') page_submission_field
from cms_session_interfaces csi,
table(xmlsequence(extract(csi.interface_xml, '//root-interface/page-group/display-page'))) display_pages
where csi.session_id = 41
and csi.interface_id = 596
(the specified session_id and interface_id are just for testing purposes)
This returns two rows consisting of the PAGE_ID and an object of XMLType containing the page-submission fields. Almost there, but not quite; any suggestions would be appreciated.

As Marco said, xmltable is very handy:
SQL> with cms_session_interfaces as (
2 select XMLType('
3 <root-interface>
4 <page-group>
5 <display-page validation-state="new">
6 <id>21</id>

8 <page-submission-field>F39EF21</page-submission-field>
9 <page-submission-field>F85FG3E</page-submission-field>
10 <page-submission-field>F73EF58</page-submission-field>
11 <page-submission-field>FA4939F</page-submission-field>
12 </page-submission-fields>
13 </display-page>
14 <display-page validation-state="new">
15 <id>22</id>
16 <page-submission-fields>
17 <page-submission-field>FDE77A4</page-submission-field>
18 <page-submission-field>FF3AD33</page-submission-field>
19 </page-submission-fields>
20 </display-page>

23 from dual)

(urgent) How to make sumarize query against XMLType?

Hello,
i have xml document like this
<List>
<Item>
<A>10</A>
554
<C>25.5.2005</C>
</Item>
<Item>
<A>20</A>
49
<C>26.5.2005</C>
</Item>
<Item>
<A>30</A>
184
<C>27.5.2005</C>
</Item>
</List>
in xmltype variable (not table column) and i need e.g. sum (or count or something like that) values in xpath /List/Item/B in one document.
Is there some quick and elegant way to do this?
Thanks for quick help.

Maybe the below will help.
Did you look at building a view over the xmltype extracting the values into a relational type view, then using the view to sum up the values.
Jonthan Gennick has an article on the Oracle OTN website with the below code.
CREATE VIEW cd_master (Title, Artist, Website, Description) AS
SELECT extractValue(value(x),'/CD/Title'),
extractValue(value(x),'/CD/Artist'),
extractValue(value(x),'/CD/Website'),
extractValue(value(x),'/CD/Description')
FROM CD331_TAB x;
CREATE INDEX by_artist ON CD331_TAB x (
extractValue(value(x),'/CD/Artist'));
ANALYZE TABLE cd331_tab COMPUTE STATISTICS FOR TABLE;
ANALYZE INDEX by_artist COMPUTE STATISTICS;

XPath query on a CLOB?

Does anyone know if there is an easy way to run an XPath query against a CLOB column? I know it's simple if the column is XMLType, but what if it's a CLOB?

Does CLOB store XML? If so, simply use XMLTYPE(clob_column).

Xpath query depenedent on new line chars

Hi,
I am trying to run an XPath query against a String which contains the XML. I am using Apache Commons IOUtils
to convert String to InputStream
If the String contains new line chars in it then I get unexpected results. However if XML is one looong string then there
is no problem.
What can I do to avoid this problem.
 public static void main(String[] args)
 throws XPathFactoryConfigurationException,
 XPathExpressionException, ParserConfigurationException,
 SAXException, IOException {
 // System.out.println(XML);
 XPathFactory xpathFactory = XPathFactory
 .newInstance(XPathFactory.DEFAULT_OBJECT_MODEL_URI);
 XPath xpath = xpathFactory.newXPath();
 DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance()
 .newDocumentBuilder();
 // Use XML_STRING as the xml to reproduce the error
 Document document = documentBuilder.parse(IOUtils.toInputStream(XML_STRING));
 NodeList xpathResult = (NodeList) xpath.evaluate("/Envelope/Body",
 document, XPathConstants.NODESET);
 Node node = xpathResult.item(0).getFirstChild();
 String requestName = node.getNodeName();
 requestName = requestName.split(":",-1)[1];
 System.out.println(requestName);
 String sessionIdXqry = "/Envelope/Body/" + requestName + "/sessionId";
 System.out.println(sessionIdXqry);
 String sessionId = (String)xpath.evaluate(sessionIdXqry, document, XPathConstants.STRING);
 System.out.println("SessionID = " + sessionId);
 }

You can't call methods in EL like that - write a custom tag that transforms the data in the way you want (replacing newlines with " "). Then:
<something:yourNewTag text="${row.description}" />

XPath query to test for the existence of a tag

I have the following piece of XML and I need to write a query against it that will check for the existence of the <content> tag in XML body... In other words, I want to get the row if the <content> tag is absent from the Asset portion of the metadata but only for Asset_Class = "encrypted"

Hi,
You may use this in the WHERE clause :
EXISTSNODE(xmltype_column, 'ADI/Asset/Asset[Metadata/AMS/@Asset_Class="encrypted"]/Content') = 0The XML has to be stored in an XMLType column, is that the case?

Query in XMLType

I have stored a typical Purchase Order List as XMLType in
Oracle. The structure looks roughly as -
<polist>
<po>
<customer>
<lineitems>
<lineitem>
<item>
<price>
<quantity>
So my polist has multipe po's and each po's has multipe items.
Now, I want to perform following xpath query -
- /polist/po/lineitems/lineitem/item[price="$100"]
In other words, find me an "item with specific price" from list
of all the items in all the po's in my polist.
From what I understand, predicates are not support by XPATH in
Oracle. How can I achieve this using SQL & Extract/exist ?
Any thoughts ??

Steve:
Thanks for your response. Your solution works !! BTW, your book
has been very handy in my work.
Now, I am taking the same PO and trying to store it into
seperate tables. My document structure is similar to Example 12-
20 in your book (Oracle XML Applications) - department with
several employees. In my case, I have a purchase order with
several lineitems.
Essentially, I followed the example and got the code (written by
you) from Oreilly website to make it work with my example. Now
the problem is when I use putXML to save, the first level gets
saved with no problem.
So, as shown in the snippet below -
>>>>
<?xml version="1.0" encoding='UTF-8'?>
<ROWSET>
<ROW>
<PO_ID>10</PO_ID>
<LINEITEMS>
<LINEITEM>
<ID>7782</ID>
<PRICE>100</PRICE>
<TAXRATE>24</TAXRATE>
<QUANTITY>20</QUANTITY>
<DISCOUNT>10</DISCOUNT>
</LINEITEM>
>>>>
If I don't include the "LINEITEM" data, the instead of trigger
fires properly and the PO_ID makes it to the po_table when I
use "putXML" utility.
BTW, I modeled everything like example 12-20 - po_table,
lineitem_table, lineitem_type, lineitem_list, instead of
trigger, po_view, etc...
Now, when I try to use the "putXML" to insert data at both
levels - po and lineitem as shown in above snippet of input xml
doc, I get the following exception -
java OracleXML putXML -user "scott/tiger" -fileName bar.xml po_view
oracle.xml.sql.OracleXMLSQLException: 'java.sql.SQLException:
Non supported character set: oracle-ch
aracter-set-178' encountered during processing ROW element 0.
All prior XML row changes were rolled
back. in the XML document.

I tried several variation by changing the encoding in my XML
document to - UTF-8, Unicode, etc..
I am using Oracle 9i (9.0.1.1) on windows 2000.
If you need additional information, please let me know !!

Query on XMLType! URGENT!!!

Please, what the most efficient way to query a xmltype column?
My xml's are 250KB ~ 1.5 MB and my table have over 130.000 records.
I have tried:
1) interMedia -> create index [indexname] on [table] (field) indextype is ctxsys.context parameters ('section group path_section_group')
but results a error on creating...
2) Table Functions, but a enough memory error results...
3) create index on xpath directly, but the repetead tag's are discarded...
I don't know what to do...
Please, help me!!!
Thanks...

XPath query rewrite and insertChildXML (10g2): Help?

Hi all,
I have a registered schema for a <log> document. The schema defines an element /log/logData and under that there, /log/logData/data having maxOccurs="unbounded". So the form of documents is
<log>
<logData>
<data>a</data>
<data>b</data>
<data>c</data>
</logData>
</log>
In the schema definition I have enabled "storeArrayAsVArray='true'". The <data> elements are stored in a nested table. Every type is stored object-relationally.
To an instance documen, I add <data> elements so:
UPDATE log SET object_value = insertChildXML(object_value, 'log/logData', 'data', '<data>foo</data>') WHERE existsNode ('/log[@uid="foo"]')
The call succeeds but the problem is that I need to make this call thousands of times. Initiallly the call might take 100 ms, but after a few hundred inserts inserting a single element takes over a second, and the time keeps increasing.
I believe at least part of the problem is that XPath query rewrites are not working for this call.
Following Chapter 6 of Oracle XML DB Developer's Guide, to debug the problem I have switched on
ALTER SESSION SET EVENTS '19021 trace name context forever, level 1';
and then every invocation causes:
ORA-19022: XML XPath functions are disabled
indicating that Oracle could not rewrite the query. Then I set
ALTER SESSION SET EVENTS '19027 TRACE NAME CONTEXT FOREVER, LEVEL 8192'
to obtain a trace file. Here is a portion of that trace:
*** 2005-10-30 16:54:44.984
*** ACTION NAME:() 2005-10-30 16:54:44.968
*** MODULE NAME:(SQL*Plus) 2005-10-30 16:54:44.968
*** SERVICE NAME:(SYS$USERS) 2005-10-30 16:54:44.968
*** SESSION ID:(137.38364) 2005-10-30 16:54:44.968
NO REWRITE

NO REWRITE
 Reason ==> xseq:not optuop
NO REWRITE
 Reason ==> not SQLX operand
NO REWRITE
 Reason ==> non sqlx expression input
NO REWRITE
 Reason ==> non rewritable sqlx input
NO REWRITE
(the rest of the file repeats these lines)
I have no idea how to interpet that! Can anyone out there offer some insight/assistance?
Thanks if you can,
Hugh

Below is a complete example script. Cannot seem to get rewrite for even this simple case. By that I mean, executing both of the SELECT statements near the end yield the ORA-19022, and that executing the insertChildXML takes progressively longer to execute the more child elements there are.
Any pointers appreciated!
Hugh

XPATH query behaves differently depending on presence of default namespace

I'm curious to know why an XPATH query seems to behave differently depending on whether the default namespace is present in the query.
My test case is as follows:
I use a table called xml_messages (id number, message xmltype) containing two rows - one where xmlns is specified and the other without.
1. Default namespace is specified:

Next, I use the following two queries to get attribute values from the xml messages:
First query using xmlns:
select extractvalue(value(v),'/Product/@Ind' ) ind
, extractvalue(value(v),'/*/@Ind' ) ind2
from xml_messages f
, TABLE(XMLSequence( extract(f.message
 ,'/Bereken/Reglementen/Reglement/Producten/Product'
 ,'xmlns="http://schemas.myco.nl/services/IPP"'
 ))) v
where f.id = 1; -- Selects from the xmltype message that does have xmlns specified
This returns (as the first row)
IND IND2
____ 1002
^
|------ Nothing is returned by the XPATH /Product/@Ind
Second without using xmlns
select extractvalue(value(v),'/Product/@Ind' ) ind
, extractvalue(value(v),'/*/@Ind' ) ind2
from xml_messages f
, TABLE(XMLSequence( extract(f.message
 ,'/Bereken/Reglementen/Reglement/Producten/Product'
 ))) v
where f.id = 2; -- Selects from the xmltype message that has no xmlns
This returns (as the first row)
IND IND2
1002 1002
According to XMLSpy, the correct XPATH to get the "Ind" attribute is "/Product/@Ind" so what I dont understand is why query one doesnt return any data when using a default namespace.
The XPATH "/*/@Ind" works in both cases and can be used as a workaround, but it seems less elegant than using the proper XPATH.
I've tried this test case in 9i and 10g, in sqlplus and TOAD, with the same results in all cases.
Can anyone provide some insight as to why this behavior occurs?

Thanks, A_Non,
adding the third parm to the extractvalue part of the query works.
ie:
select extractvalue(value(v),'/Product/@Ind', 'xmlns="http://schemas.myco.nl/services/IPP"' ) ind
, extractvalue(value(v),'/*/@Ind' ) ind2
from xml_messages f
, TABLE(XMLSequence( extract(f.message
 ,'/Bereken/Reglementen/Reglement/Producten/Product'
 ,'xmlns="http://schemas.myco.nl/services/IPP"'
 ))) v
where f.id = 1;
I had not expected this because I thought the xml fragment returned by the extract didnt include the default namespace.
However, when looking at the query in more detail, its clear Oracle automatically includes the xmlns part in the returned xml fragment.
One of the rows in the xml fragment:
<Product xmlns="http://schemas.myco.nl/services/IPP" Ind="1002" ogr="27098.00" bbr="27098.00" igl="65" elt="130" pgs="63758.00" slt="65" plt="0" reg="0" orf="0"/>

How to use one query against multiple table and recieve one report?

I have duplicate tables, (except for their names of course) with commodities prices. They have the same column headings, but the data is different of course. I have a query that gives me a certain piece of information I am looking for but now I need to run this query against every table. I will do this every day as well, to see if the buying criteria is met. There are alot of tables though (256). Is there a way to say run query in all tables and return the results in one place? Thanks for your help.

hey
a. the all 256 tables whuld be one big partitoned table
b. you can use all_tables in order to write a select that will write the report for you:
SQL> set head off
SQL> select 'select * from (' from dual
2 union all
3 select 'select count(*) from ' || table_name || ' union all ' from a
4 where table_name like 'DB%' AND ROWNUM <= 3
5 union all
6 select ')' from dual;
select * from (
select count(*) from DBMS_LOCK_ALLOCATED union all
select count(*) from DBMS_ALERT_INFO union all
select count(*) from DBMS_UPG_LOG$ union all
remove the last 'union all', and tun the generated quary -
SQL> set head on
SQL> select * from (
2 select count(*) from DBMS_LOCK_ALLOCATED union all
3 select count(*) from DBMS_ALERT_INFO union all
4 select count(*) from DBMS_UPG_LOG$
5 );
COUNT(*)

Best practice for a same query against 2 different tables

Hello all,
I want to extract info about tablespaces storage, both permanent and temporary. For that I use 2 different cursors that do exactly the same query but against a different table (dba_data_files and dba_temp_files).
CURSOR permanentTBSStorageInfo (tablespaceName VARCHAR2) IS
SELECT file_name, bytes, autoextensible, maxbytes, increment_by
FROM dba_data_files
WHERE tablespace_name = tablespaceName;
CURSOR temporaryTBSStorageInfo (tablespaceName VARCHAR2) IS
SELECT file_name, bytes, autoextensible, maxbytes, increment_by
FROM dba_temp_files
WHERE tablespace_name = tablespaceName;
First I'm bothered that I have to use 2 cursors to execute the same query against 2 different tables. Is there no another way around?
Then I fetch the results of this cursors in 2 different loops because I didn't find a way to dynamically call the cursors. I am looking for best practice here, knowing that I will do the same parsing against the results of the 2 cursors.
Thank you,

Hi
Check whether the below query is helpful or not
select      fs.tablespace_name "Tablespace",
     fs.tempspace "Temp MB",
     df.totalspace "Total MB"
     from
     (select
     tablespace_name,
     round(sum(bytes) / 1048576) TotalSpace
     from
     dba_data_files
     group by
     tablespace_name
     ) df,
     (select
     tablespace_name,
     round(sum(bytes) / 1048576) tempSpace
     from
     dba_temp_files
     group by
     tablespace_name
     ) fs
     where
     df.tablespace_name = fs.tablespace_name;
Thanks

Error when running a query against Multiprovider using 0FIGL_VC1

Hi SAP Gurus,
I'm creating a MultiProvider for FI-GL.It has 2 Cubes.one is 0FIGL_VC1 (Virtual Cube) and other one is Customised Cube.When I run Query against this MultiProvider with the combination of basic cubes key figures,I'm getting an error
'Abort system error in Program SAPLRSDRC and Form RSDRC/Form DISPATCHER/RECEIV '
then system gets disconnected from the Server .
Please give me the solution to fix it & I'll assign the points .
Thanks & Regards

Hello Suman,
Check the table rszglobv for this variable - ZCONLEH.
If it is available there then see which infoobject it belongs to and then look for that in the query designer. May be resaving the query solves the issue.
If the variable is not available in the table, then it seems that the variable is lost and you might have to recreate it for keeping the semantics of the query the same as it was before the upgrade.

Query against materialized view from stored procedure brings back empty row

I have a stored procedure that runs a query against a materialized view. When I run the query outside the SP it works just fine. When I change the MV to a table name, the SP works. When I change it back to the MV i get an empty row. Any ideas? The code is below:
PROCEDURE getAuth     (p_naid        IN NUMBER,
                         p_scope       IN VARCHAR2,
                         o_xml_data    OUT SYS_REFCURSOR
                         ) IS
BEGIN
    IF p_scope = 'Approved' THEN
      OPEN o_xml_data FOR
        SELECT naid,
               p_naid,
               auth_type,
               xml_data
        FROM some_mv
        WHERE naid = p_naid;
      RETURN;
      CLOSE o_xml_data;
... the rest of the procedure ...

does procedure contain EXCEPTION handler?
if so, then remove, delete & eliminate EXCEPTION handler (at least during testing & debugging)
