How to Index a XMLTYPE table

I am using a xmltype table for parsing the xml file and then storing the tag values into someother tables.
The table syntax
CREATE GLOBAL TEMPORARY TABLE ATLAS.XML_PROCESS
XML_DATA XMLTYPE
ON COMMIT DELETE ROWS;
At a time i will parse only one xml file. And them the content will be deleted and then i will parse another xml file.
The parsing of the xml file is taking much CPU time and also it is taking more FETCH time. ( i have seen from the trace file)
Do i need to create any index on this table?
Please suggest me how can i imrove the performence.
Thanks

The fields in the INDEX of the Table EKPO should be in the same sequence as in the WHERE clasuse?

Hi,
You minimize the size of the result set by using the WHERE and HAVING clauses. To increase the efficiency of these clauses, you should formulate them to fit with the database table indexes.
Database Indexes
Indexes speed up data selection from the database. They consist of selected fields of a table, of which a copy is then made in sorted order. If you specify the index fields correctly in a condition in the WHERE or HAVING clause, the system only searches part of the index (index range scan).
The primary index is always created automatically in the R/3 System. It consists of the primary key fields of the database table. This means that for each combination of fields in the index, there is a maximum of one line in the table. This kind of index is also known as UNIQUE. If you cannot use the primary index to determine the result set because, for example, none of the primary index fields occur in the WHERE or HAVING clause, the system searches through the entire table (full table scan). For this case, you can create secondary indexes, which can restrict the number of table entries searched to form the result set.

How to 'DESCRIBE' a XMLType table

Hi,
When I describe a XMLType table, the output is truncated as follow :
SQL> desc scott.purchaseorder
Name Null? Type
TABLE of SYS.XMLTYPE(XMLSchema "http://localhost:8080/home/SCOTT/poSource/xsd/purchaseOrder.xsd" Ele
Is there any way to show the complete string ?
I have tried 'SET LONG' and 'SET LINESIZE', but not succeeded.
Any suggestion ?

I've also found under windows that using sqlplus within a command window gives better results with wrapping text than using sqlplusw (the gui version). Also Oracle are deprecating sqlplusw in favour of the SQL worksheet in enterprise manager from version 10 onwards, although it does still get installed at the moment if you really want to keep using it.

How to check a XMLTYPE table for corrupted (not invalid!) XML records ??

Hello,
I'd like to get help on the following issue, please. I need to check the XML data in a number of tables with XMLTYPE data type. Some of the data is corrupted but in terms not that the XML format is wrong but there is no XML at all in the fields but just only, for example, control characters (no tags, no anything, just corrupted data).
So, I have made a PL/SQL procedure cursor to get all the tables from a list, and then another cursor inside to browse each table for corrupted records. But can you help me how to check this? Any of the XML functions like for example: XMLIsValid, isFragment(), getrootelement(), etc. return to me an Oracle error "ORA-31011 XML parsing failed" and the procedure gets stuck on the first found bad record. But I need to continue and check all of them. Is it possible to get the ORA-31011 error with EXCEPTION, write to a logging table the corrupted record ID, and then continue?
Here is my simple procedure:
CREATE OR REPLACE PROCEDURE CHECKXML (v_schema in VARCHAR2)

     valid_flag     number;
     criteria     VARCHAR2(20);
     tab1          VARCHAR2(20);
     tab2          VARCHAR2(20);

     criteria := 'XMLTYPE';
     sql_stmt1 := 'select id, path from ' || v_schema || '.stubfiles where type=:bcriteria';
     open c1 for sql_stmt1 using criteria;
     loop
     begin
          fetch c1 into cur_tab, cur_appl;
          exit when c1%notfound;
               insert into system.log_table values (sysdate, v_schema, 'next table', 'id ' || cur_tab, 'appl ' || cur_appl, '');
          sql_stmt2 := 'select t.recid, t.xmlrecord.isFragment() from ' || v_schema || '.' || cur_tab || ' t';
          open c2 for sql_stmt2;
          loop
          begin
          fetch c2 into cur_rec, valid_flag;
               exit when c2%notfound;
               insert into system.log_table values (sysdate, v_Schema, 'next record', 'id ' || cur_tab, 'recid ' || cur_rec, 'valid ' || valid_flag);
               commit;

          end;
          end loop;

How to link a XMLType table to a repository?

I follow following steps:
1) register a schema and generate a default table
2) insert XML documents ( specifing the schema just registered) into the table by using SQL
But how to let those XML documents show up in the repository so that users can access to them by using HTTP/FTP so that any update done to the table will be reflected in the repository and vice versa.
I tried many things but no luck.

Everything looks OK to me. In the folllowing example the createResource() is the equivilant of the WebDAV copy. Do you have multiple database instances running on the server machine. It is possible that the WebDAV connection is connected to another database instance.
What folder are you copying the data into
Can you do

Join two xmltype table using Xquery

I am wondering how to join two xmltype tables in xml db database. both tables are schema based object-relational tables.
these are the examples:
academicProgram table contain batch of academicprogram.xml entries
<academicProgram>
<listOfCourse>
<course><id>1</id></course>
<course><id>2</id></course>
</listOfCourse>
</academicProgram>
course table contain all the course entries, each of them is an xml file based on the the course schema. for example,
course1.xml
<course>
<id>1</id>
<title>xxxxxxx</title>
<description>xxxxxxxxxxxxxx</description>
</course>
I used the following xquery code to merge the detailed course information from course table to the academic program information
select *
from XMLTable(
for $program in ora:view("HTU", "ACADEMICPROGRAM")
return <academicProgram xmlns="http://www.mdanderson.org/schema/APEP/courseCatalog"
     for $node in $program/academicProgram/node()
     return if (name($node) eq "listOfCourse")
          then (
               <listOfCourse>{
               for $i in $node/course
               for $j in ora:view("HTU", "COURSE")/course
               where $i/id eq $j/id
               return $j
               }</listOfCourse>
          else $node
     </academicProgram>
it did return what I want, but the problem is it take more than 5 minutes to finish. is there someway to make it run faster? I have been struggling for a week, please help.
thanks in advance.

How to improve performance of a query that is based on an xmltype table

Dear Friends,
I have a query that is pulling records from an xmltype table with 9000 rows and it is running very slow.
I am using XMLTABLE command to retreive the rows. It is taking upto 30 minutes to finish.
Would you be able to suggest how I can make it faster. Thanks.
Below is the query.....
INSERT INTO temp_sap_po_receipt_history_t
(po_number, po_line_number, doc_year,
material_doc, material_doc_item, quantity, sap_ref_doc_no_long,
reference_doc, movement_type_code,
sap_ref_doc_no, posting_date, entry_date, entry_time, hist_type)
SELECT :pin_po_number po_number,
b.po_line_number, b.doc_year,
b.material_doc, b.material_doc_item, b.quantity, b.sap_ref_doc_no_long,
b.reference_doc, b.movement_type_code,
b.sap_ref_doc_no, to_date(b.posting_date,'rrrr-mm-dd'),
to_date(b.entry_date,'rrrr-mm-dd'), b.entry_time, b.hist_type
FROM temp_xml t,
XMLTABLE(XMLNAMESPACES('urn:sap-com:document:sap:rfc:functions' AS "n0"),

For large XML's, you can speed up the processing of XMLTABLE by using a registered schema...

How to create index on xmltype column

I have a table having only one column xmlcontent (xmltype). This table stores xml data of about 10GB size. I'm using extract value to move the data to staging tables.
How can I create index on xmltype column?
Create index indexname on table (column) doesn't seem to work.
Sample xmlstructure is given below
<Root>
<Type>Insert</Type>
<Date>2006-12-29</Date>
<Source>8</Source>
<id>data</id>
<key_flds>
<fld><id>Key1</id><val>C</val></fld>
<fld><id>Key2</id><val>429672</val></fld>
<fld><id>Key3</id><val>8</val></fld>
</key_flds>
</Root>
I need to do extract value on all tags and move them to corresponding relational tables.

Hi, you need to create them using something like this (what I have used and work rather well - if I did not load the xml into an xml table, the processing took about 10 minutes, while the indexed xml table took just a few seconds). statute_xml is the table name and sxmldoc is the xml column/field.
create index desc_idx on statute_xml
(sxmldoc.existsNode('/SimpleTypeCompanion/EnumerationValue/@description'))
create index sid_idx on statute_xml
(sxmldoc.existsNode
('/SimpleTypeCompanion/EnumerationValue/Text')
create index effdate_idx on statute_xml
(sxmldoc.existsNode
('/SimpleTypeCompanion/EnumerationValue/@effectiveDate')
Hope this helps.

How to shift index in a table

Hey,
My program collects 5 pieces of information per object from user. Some of the input data is in String format, rest are Integers. I create an object from this data and put in into a table. My table contains max 10 pieces of information.
I have editing options for this data, which are erase one or all pieces, or modify a piece. I erase data by simply setting the index to null. Erasing one piece is incomplete atm, here's why:
Say I have 5 pieces in table, and I erase the one with index of 0. I can't print my information because the table starts with a null value:
int index = 0;
if (table[index] != null) { System.out.println(data);} ..
My guess is that I can solve this problem by decreasing the index of pieces greater than the modified one by 1. I can imagine that I'll be using for loop here. This is where I run out of ideas: is it possible to just modify the index, or do I have to rewrite the data again?
Any help is appreciated,
br,
nomi

I think using for loop would be the easiest way (?).
I'm filling the table as simply as:
items[index] = new table (value, quality..);Using LinkedList seems a bit far fetched for me. But
again, if I am to use for loop, I think I would have
to rewrite the data to appropriate index?Why is a List far fetched? Type of List you pick depends on how you use the list (whether you want RandomAccess, etc.).
List items = new ArrayList(); // or LinkedList
items.remove(index); // Remove the item at index.To use an array:
Table [] items = new Table[20]; // whatever size
items[index] = new Table(value, quality, ...);
// To remove:
System.arraycopy(items, index, items, index+1, items.length-(index+1));
items[items.length-1] = null;

How to get selected row index of a Table ?

hi gurus,I'm new to Webdynpro for abap
I'm displaying just Flight details in a Table so
how to get selected row index of a Table and need to be display in Message manager.

Hi,
For getting the row index use the following code.
DATA lo_nd_node TYPE REF TO if_wd_context_node.
DATA lo_el_node TYPE REF TO if_wd_context_element.
DATA index TYPE i.
* navigate from <CONTEXT> to <NODE> via lead selection
lo_nd_node = wd_context->get_child_node( name = wd_this->wdctx_node ).
lo_el_node = lo_nd_node->get_lead_selection( ).
index = lo_el_node->get_index( ).
node is the name of the node which is binded to the table.
For printing the message u can use code wizard.
Press ctrl-F7. Now Select generate message.
IN this select the method REPORT_SUCCESS
In the code now u can give index to Message text Exporting parameter. Comment receiving parameter.
Write the whole code in onLeadSelect of the table.

How to create a relational view base on an xmltype table which included sev

Hi,
I am using oracle 11.2.0.1.0.

Thanks.
for examle:
SQL> SELECT OBJECT_VALUE FROM document;
Edited by: Cow on Jan 6, 2011 7:57 PM

For example I already have these three xml files inserted into the document xmltype table.
These xml files have same schemas. I have attached below.
I want to show all elements/attribute values in xml files to relational view.
Is this possible to create one big relational view to show everything
or I have to create three separate relation views then use UNION to put together? Thanks a lot. Cow

How much time it take to rebuild an index for a table with 20 millions rows

Hi all,
i need to rebuild the index of a table containing 20 000 000 row (i don't know why the other people working on this didn't think of rebuilding the index regularly, because i asked and apparently it has never been done :cry: :cry:) i am not a sql developper nor a DBA so i can't mesure how long it take to rebuild the index, does any one have an idea (aproximativly of course :aie:), the other question is there any formula to use in order to calculate how often to rebuild the indexes (i can for example retieve how much rows are delated or inserted daily ...)
Thanks again
Taha

:aie: that's why i am asking because i don't know (and to be sure which solution is best)
so the table is like this (the columns) :
45 varchar2, 5 timestamp, 30 Number no LOB columns, (15 indexes : 5 unique indexes and that those indexes uses at a maximum 4 columns)15 indexes - 100,000 deletes: this could mean 1,500,000 block visits to maintain index leaf blocks as the table rows are deleted. If you're unlucky this could turn into 1,500,000 physical block read requests; if you're lucky, or the system is well engineered this could be virtually no physical I/O. The difference in time could be huge. At any rate it is likely to be 1,500,000 redo entries at 250 - 300 bytes per entry for a total of about 400MB of redo (so how large are your redo logs and how many log switches are you going to cause).
yes the tables is used by an application so (update, insert ) can take place at any time
for the deletion , there is the batch which does a mass delete on the table ( 4 or 5 time each day)
You haven't answered the question - how long does it take to do a sample batch delete.
If you can enable SQL tracing, or take a before/after snapshot of v$sesstat or v$session_event for the session as it does the delete then you can get some idea of where the time is going - for all you know it might be spending most of its time waiting for a lock to do away.
>
"How many leaf blocks are currently allocated to the index(es) ?" how can i answer to this question ? may be if i check the all_objects table ?
If you keep your statistics up to date then dba_indexes is a good place, cross-checked with dba_segments, and you can use the dbms_space package for more detail. I have a code sample on my blog which allows you to compare the current size of your indexes with the size they would be if rebuilt at some specific percentage: http://jonathanlewis.wordpress.com/index-sizing/ (It's such good code that Oracle Corp. has copied it into MOS note 989186.1)

How to get row index of data table in the while ValueChangeListener fired?

Hi,
i have a data table in my page, which contains various components like inputText, selectOneChoice in each row.
i am invoking a method ValueChangeListener attribute of the selectOneChoice component. I have given the autoSubmit=true for this component.
<tr:selectOneChoice id="ratingModelType"
value="#{childRatio.ratingModelType}" binding="#{pageManager.form.bindRatioType}"
valueChangeListener="#{pageManager.form.onRatingModelTypeChange}" autoSubmit="true"
contentStyle="width:150px" required="#{!childRatio.disableChildRatioRatingModelType}"
requiredMessageDetail="#{appBundle['error.ratingModelTypeShouldNotBeEmpty']}">
<f:selectItems value="#{pageManager.catalog['Rating Model Type']}" />
<tr:selectOneChoice>In that method i want to fetch the map(with all updated values) relevant to the currently modified row of the table.
Since i am not using the selectionListener or any radio buttons in the page i am not able to get the row index of the table.
somebody please tell me how to get the row index of the table, while ValueChangeListener fired?
Thanks in advance.

How to add index to PSA table?

Hi , Experts
as title, I want to add index to PSA table.
my scenario is as below:
We have already initialized 2LIS_03_BF with NOT blcok business user(it's due to our company could not stop R/3 system, anyway), so there are 6 years data in the PSA table, it's very huge records in PSA more than 48 million records, because of we NOT stop R/3 business during initialization, so I have to search some common data between delta records and full records(it's due to this common data contain duplicate record, I need find them and delete the duplicate record and make sure the data is correct).
This is mean The selection is too expensive as it has to look for more than five thousand delta record between more than 48 million full records. fow now I have already tigger this search job use a program, but it's still run for 7 days, still not finished yet, it drive me crazy. so I mean if I can create a index for PSA table, and this action will drive the above compare work more quickly than before? or have any other way for my scenario?
Thanks in advance.
Best Regards,
Bruce

Hi,
See the PSA Name in RSTSODS table and then in SE11 you can create Index. But the load will become slow if you don't drop the Index.
Use 2LIS_03_BX, 2LIS_03_BF, 2LIS_03_UM to 0IC_C03 Cube and design the report.
Use :See the steps how to load the data to 0IC_C03.
Treatment of historical full loads with Inventory cube
Setting up material movement/inventory with limit locking time
If it is BI 7 then for BX in in DTP in Extraction Tab you need to select Extacrion mode = NON-Cumulative option.

How   to find global index in partition table

Hi Solomon,
so I have to identify partition & index are created or not,
also I have check the status of index ( both global and local)So what's the problem? Table/index partition is an object, so you can query DBA_OBJECTS:
SELECT SUBOBJECT_NAME,
        CREATED
FROM DBA_OBJECTS
WHERE OWNER = partitioned-table-owner
    AND OBJECT_NAME = partitioned-table-name
    AND CREATED >= TRUNC(SYSDATE)
/This will give you partitions created today. So if you run this right after your job (I hope your job doen't run too close to midnight), you'll get table partition name your job created. Same logic can be applied to indexes.
