From XML in CLOB to relational table doubt
versions 11.2.0.2.0 / 10.2.0.4.0
It's a long time, no see since my last dealing with xml and no luck to have an attribute value returned into the relational table.
It's *<IntrBkSttlmAmt Ccy="???">999999</IntrBkSttlmAmt>*
For the rest the below works in both versions but used on an xml having a 10000 <CdtTrfTxInf> on 11g it took 9 seconds and was killed because no answer was produced after 30 minutes on 10g. A colleague using java loaded the relational table in 34 seconds on 10g and produced the relational table on 11g in just 5 seconds.
The 10g version is surviving with no xmldb installed and there are rumors our thinking heads didn't succeed to deactivate it on 11g yet.
Any suggestion concerning alternate ways to produce a relational table from an xmltype located in a clob column of a relational table are welcome
(looking at CLOB in XML to Normal table Best approach? I thought too many xmltable would have to be used)

Hi,
It's a long time, no see since my last dealing with xml and no luck to have an attribute value returned into the relational table.When you use this :
<Ccy>{$r/IntrBkSttlmAmt/@Ccy}</Ccy>That doesn't set the value of the Ccy element with the attribute value, but actually add the attribute Ccy to the element Ccy, which results in
<Ccy Ccy="???"></Ccy>Knowing that, you have three options :
1) Leaving the XQuery as it is and using this instead in the COLUMNS clause :
ccy varchar2(50) path '/rw/Ccy/@Ccy',2) Modifying the XQuery to get the atomic value out of the attribute (using the fn:data function) :
<Ccy>{fn:data($r/IntrBkSttlmAmt/@Ccy)}</Ccy>3) Simplifying the whole thing, something like :
select v.instrid, v.endtoendid, v.txid, v.cd, v.ccy,
replace(v.intrbksttlmamt,'.',',') as intrbksttlmamt, v.chrgbr, v.bic1, v.nm1, v.adrline11, v.adrline12, v.ctry1, v.iban1,

Date insertion from large XML document (clob) into relation table very slow
Hi Everybody!
I'm working with Oracle 9.2.0.5 on Microsoft Windows Server 2003 Enterprise Edition.
The server (a test server) is a Pentium 4 2.8 GHz, 1GB of RAM.
I use a procedure called PARITOP_TRAITERXMLRESULTMASSE to insert the data contained in the pXMLDOC clob parameter in the table pTABLENAME. (You can see the format of the XML document below). The first step on this procedure is to verify that the XML document is not empty. If not, the procedure needs to add a node in the document, in every <ROW> tag. This added node is named âRST_IDâ. Itâs the foreign key of each record. I can retrieve the value of each <RST_ID> node in an other table in which the data has been previously added (by the calling procedure). When each of the <ROW> elements has been treated, the PARITOP_INSERTXML procedure is called. This procedure uses DBMS_XMLSAVE.INSERTXML to insert the data contained in the XML document in the specified table.
(Below, you can see the code of my procedures.)
With this information, can you tell me why this treatment is very very very slow with a large XML document and how I can improve it?
Thank you for your help!

Storing XML data in CLOB and relational tables
I would like to ask whether there is a possibility to store XML data using normal relational tables and CLOBs in the same time. For example I have some XML data (structured data) which I would like update very often and some which are only a kind of description. I found something about it in http://technet.oracle.com/tech/xml/infoocs/otnwp/about_oracle_xml_products.htm . But I do not know how to use Oracle8i views and some functionality of XML SQL Utility to retrieve XML data in one file.

Czesc Maciek,
There are some good examples with XSQL Servlet. From what I understand you have one XML file and you need to save a portion of document in relational tables and other portion in CLOB.
Yes, you can do that.
You can do it many ways. I can suggest (2).
1. Use the views
2. call your java procedure that will do
the xml processing, brake it down and insert
releval frogments into different tables/columns

How to extract data from xml and insert into Oracle table
Hi,
I have a large xml file. which will have hundreds of the following transaction tags having column names and there values.
There is a table one of the schema with coulums "actualCostRate","billRate"....etc.
I need to extract the values of these columns and insert into the table
<Transaction actualCostRate="0" billRate="0" chargeable="1" clientID="NikuUK" chargeCode="LCOCD1" externalID="L-RESCODE_UK1-PROJ_UK_CNT_GBP-37289-8" importStatus="N" projectID="TESTPROJ" resourceID="admin" transactionDate="2002-02-12" transactionType="L" units="11" taskID="5017601" inputTypeCode="SALES" groupId="123" voucherNumber="ABCVDD" transactionClass="ABCD"/>

Select data from an XML Column in a Relational Table
Hi guys,
I read a lot of documentation from Oracle how to select xml nodes from an XML Table. The following statement works perfectly for an XML table.
select extract(OBJECT_VALUE, '/loop/loop_data/description') "DESCRIPTION"
from loop_table
where xmlexists('/loop/loop_data[type_code="212"]' PASSING OBJECT_VALUE);
BUT: how to select xml nodes (data) from a relational table with an XML column???
I'm interested in the xml data.
Thanks!

XML BLOB/CLOB to relational structure
Hi
I would like peoples views on the best approach to the folllowing scenario
We are implementing a new payments engine (major bank), the vendors DB is a mix of normal relational tables & XML including XML CLOB/BLOB. In the latter case, the original incoming payment message and the enriched outgoing payment message is stored as XML CLOB. The vendor has no OOTB reporting capabilities so our approach is to replicate the production database using GoldenGate. We then plan to cretae a fully relational oracle database as an ODS (near real time) with B.O sitting over the top for reporting. We will use Oracle Data Integrator to extract the data from the rplicated copy of the live DB every 10 mins, shred the XML clob components and store in normal relational tables in the ODI.
Does anyone see major problems with this approach and can anyone suggest a better approachHi

Approach to parse large number of XML files into the relational table.
We are exploring the option of XML DB for processing a large number of files coming same day.
The objective is to parse the XML file and store in multiple relational tables. Once in relational table we do not care about the XML file.
The file can not be stored on the file server and need to be stored in a table before parsing due to security issues. A third party system will send the file and will store it in the XML DB.
File size can be between 1MB to 50MB and high performance is very much expected other wise the solution will be tossed.
Although we do not have XSD, the XML file is well structured. We are on 11g Release 2.
Based on the reading this is what my approach.
1. CREATE TABLE XML_DATA
(xml_col XMLTYPE)
XMLTYPE xml_col STORE AS SECUREFILE BINARY XML;
2. Third party will store the data in XML_DATA table.
3. Create XMLINDEX on the unique XML element
4. Create views on XMLTYPE
CREATE OR REPLACE FORCE VIEW V_XML_DATA(
Stype,
Mtype,
MNAME,
OIDT
AS
SELECT x."Stype",
x."Mtype",
x."Mname",
x."OIDT"
FROM data_table t,
XMLTABLE (
'/SectionMain'
PASSING t.data
COLUMNS Stype VARCHAR2 (30) PATH 'Stype',
Mtype VARCHAR2 (3) PATH 'Mtype',
MNAME VARCHAR2 (30) PATH 'MNAME',
OIDT VARCHAR2 (30) PATH 'OID') x;
5. Bulk load the parse data in the staging table based on the index column.
Please comment on the above approach any suggestion that can improve the performance.
Thanks

I was not aware of Virtual column but looks like we can use it and avoid creating views by just inserting directly into
the staging table using virtual column.
Suppose OID id is the unique identifier of each XML FILE and I created virtual column
CREATE TABLE po_Virtual OF XMLTYPE
XMLTYPE STORE AS BINARY XML
VIRTUAL COLUMNS
(OID_1 AS (XMLCAST(XMLQUERY('/SectionMain/OID'
PASSING OBJECT_VALUE RETURNING CONTENT)
AS VARCHAR2(30))));
1. My question is how then I will write this query by NOT USING COLMUN XML_COL
SELECT x."SECTIONTYPE",
x."MACHINETYPE",
x."MACHINENAME",
x."OIDT"
FROM po_Virtual t,
XMLTABLE (
'/SectionMain'
PASSING t.xml_col <--WHAT WILL PASSING HERE SINCE NO XML_COL
COLUMNS SectionType VARCHAR2 (30) PATH 'SectionType',
MachineType VARCHAR2 (3) PATH 'MachineType',
MachineName VARCHAR2 (30) PATH 'MachineName',
OIDT VARCHAR2 (30) PATH 'OID') x;
2. Insetead of creating the view then Can I do
insert into STAGING_table_yyy ( col1 ,col2,col3,col4,
SELECT x."SECTIONTYPE",
x."MACHINETYPE",
x."MACHINENAME",
x."OIDT"
FROM xml_data t,
XMLTABLE (
'/SectionMain'
PASSING t.xml_col <--WHAT WILL PASSING HERE SINCE NO XML_COL
COLUMNS SectionType VARCHAR2 (30) PATH 'SectionType',
MachineType VARCHAR2 (3) PATH 'MachineType',
MachineName VARCHAR2 (30) PATH 'MachineName',
OIDT VARCHAR2 (30) PATH 'OID') x
where oid_1 = '99dd48cf-fd1b-46cf-9983';<--VIRTUAL COLUMN
insert into STAGING_table_yyy ( col1 ,col2,col3
SELECT x."SectionOID",
x."EventName",
x."OIDT"
FROM xml_data t,
XMLTABLE (
'/SectionMain'
PASSING t.xml_col <--WHAT WILL PASSING HERE SINCE NO XML_COL
COLUMNS SectionOID PATH 'SectionOID',
EventName VARCHAR2 (30) PATH 'EventName',
OID VARCHAR2 (30) PATH 'OID',
) x
where oid_1 = '99dd48cf-fd1b-46cf-9983';<--VIRTUAL COLUMN
Same insert for other tables usind the OID_1 virtual coulmn
3. Finaly Once done how can I delete the XML document from XML.
If I am using virtual column then I beleive it will be easy
DELETE table po_Virtual where oid_1 = '99dd48cf-fd1b-46cf-9983';
But in case we can not use the Virtual column how we can delete the data
Thanks in advance

Read data from xml files and populate internal table
Hi.
How to read data from xml files into internal tables?
Can u tell me the classes and methods to read xml data..
Can u explain it with a sample program...<pre>DATA itab_accontextdir TYPE TABLE OF ACCONTEXTDIR.
DATA struct_accontextdir LIKE LINE OF itab_accontextdir.
DATA l_o_error TYPE REF TO cx_root.
DATA: filename type string ,
xmldata type xstring .
DATA: mr TYPE REF TO if_mr_api.
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
IMPORTING e_content = xmldata ).
WRITE xmldata.
TRY.
CALL TRANSFORMATION id
SOURCE XML xmldata
RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.
LOOP AT itab_accontextdir INTO struct_accontextdir.
WRITE: / struct_accontextdir-context_id,
struct_accontextdir-context_name,
struct_accontextdir-context_type.
NEW-LINE.
ENDLOOP.</pre>
<br/>
Description:
In the above code snippet I am storing the data in an xml file(you know xml is used to store and transport data ) called 'xml_accontextdir.xml' that is uploaded into the MIME repository at path 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'.
The below API is used to read a file in MIME repo and convert it into a string that is stored in ' xmldata'. (This is just a raw data that is got by appending the each line of xml file).
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
IMPORTING e_content = xmldata ).
Once the 'xmldata' string is available we use the tranformation to parse the xml string that we have got from the above API and convert it into the internal table.
<pre>TRY.
CALL TRANSFORMATION id
SOURCE XML xmldata
RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.</pre>
Here the trasnsformation 'id ' is used to conververt the source xml 'xmldata' to resulting internal table itab_accontextdir, that have same structure as our xml file 'xml_accontextdir.xml'. In the RESULT root of the xml file has to be specified. (In my the root is 'shiva').
Things to be taken care:
One of the major problem that occurs when reading the xml file is 'format not compatible with the internal table' that you are reading into internal table. Iin order to get rid of this issue use one more tranformation to convert the data from the internal table into the xml file.
<pre>TRY.
CALL TRANSFORMATION id
SOURCE shiv = t_internal_tab
RESULT XML xml.
CATCH cx_root INTO l_o_error.
ENDTRY.
WRITE xml.
NEW-LINE.</pre>
<br/>
This is the same transformation that we used above but the differnce is that the SOURCE and RESULT parameters are changed the source is now the internal table and result is *xml *string. Use xml browser that is available with the ABAP workbench to read the xml string displayed with proper indentation. In this way we get the format of xml file to be used that is compatable with the given internal table.
Thank you, Hope this will help you!!!

Load XML Document/Data into relational Table
Hi All,
I have a requirement to load data in an XML file into an oracle db and subsequently split the contents into columns in an oracle table. This has to be done on the command line from a unix box which connects to a remote oracle DB.
Can some one give me a step by step procedure to do this or point me in the right direction.
thank youHi,
There can be many different way we can achieve this. Mainly depending on size of XML, complexity of XML and your use of that data (e.g. you just want to insert XML into relational or you want to write something and the generate new xmls later on).
If you go to Oracle online documentation -> Oracle XML DB Developer's guide, first 3-4 chapters will give you what you need.

Reading from XML file and updating the table ????
Hi
I have package which reads the hier.XML file and does Update inserts into the 5 tables
i have table called MAIN_tbl with the column cur_date.
The package kicks if this cur_date is one day less than the hier.XML file DT.
Currently i m manually checking this date's to make sure the Main_tbl cur_date is n sync with
hier.XML file DT.
for example :- hier.xml file DT is "20091020" then main_table cur_date should be 10/19/2009
in order to kicks of the pakage.
what i m looking to do ??
compare the hier.xml DT with the main_table cur_date,
if cur_date is -1(Preivous day) of hier.xml DT then run hier_pkg(Package)
if not then update main_table cur_date to -1(previous day) of the hier.xml DATE
Then later write the above logic to update the main_table in a procedure, and
then call the package from the procedure.
below are the top few lines of the hier.XML file which is relevant to the one which we are trying to do
<?xml version = '1.0'?>
<HIER_POSTING num ="111" HIER_TYP="CD" DT="20091020" Global="Y">
FYI : The hier.XML file is located in UNIX space.
How do i accomplish this. any idea ????
Thank you so much in advance. For giving a thought on this problem!!!Any thought on this guys ???

How to parse and retrieve records from xml files into columns in Table
Hi
I attached the thing what i tried.
Table to hold the XML COntent:
create table xmlfile(xml_con sys.xmltype);
Inserting Xml file content into the Above table:
insert into xmlfile values(sys.xmltype.CreateXml('<Root><name>RAM</name><age>23</age></Root>'))
SQL> select * from xmlfile;
XML_CON
<Root>
<name>RAM</name>
<age>23</age>
</Root>
SQL> select extractValue(xml_con, '/Root/name') content from xmlfile;
CONTENT
RAM
This one works fine
But if the file content is as below( contains MUltiple Records)
insert into xmlfile values(sys.xmltype.CreateXml('<Root><Record><name>RAM</name><age>23</age></Record><Record><name>SAM</name><age>23</age></Record></Root>'))
SQL> select extractValue(xml_con, '/Root/Record/name') content from xmlfile;
ERROR at line 1:

Querying XML data in Object Relational tables
Hi,
Can someone help me?
I have registered the purchaseorder.xsd in my database schema.
[ http://www.oracle.com/technology/oramag/oracle/03-jul/o43xml.html ]
declare
l_bfile bfile;
begin
l_bfile := bfilename(
'XMLSAMP', 'purchaseOrder.xsd');
dbms_lob.open(l_bfile);
dbms_xmlschema.registerschema('http://localhost:8080/purchaseOrder.xsd', l_bfile);
dbms_lob.close(l_bfile);
end;
This has created a table "PURCHASEORDER"
SYS_NC_ROWINFO$ SYS.XMLTYPE
It has also created object types.
select object_name from user_objects where object_type = 'TYPE' and object_name like 'XDBPO%'
XDBPO_ACTIONS_TYPE
XDBPO_ACTION_COLLECTION
XDBPO_ACTION_TYPE
XDBPO_LINEITEMS_TYPE
XDBPO_LINEITEM_TYPE
XDBPO_PART_TYPE
XDBPO_REJECTION_TYPE
XDBPO_SHIPINSTRUCTIONS_TYPE
XDBPO_TYPE
I have also inserted an xml into that table.
INSERT INTO "PURCHASEORDER"
VALUES
xmltype
getFileContent('ADAMS-20011127121040988PST.xml','XMLSAMP')
Now how do I retrieve the data from this table and the other object types?
Is extractvalue the only method? I have gone thru examples in the net but everything uses the element names in xml document and not the object type names.
For example to retreive the lineitem details, this query can be used
SELECT extractValue(value(d),'/Description')
FROM "PURCHASEORDER" p,
table (xmlsequence(extract(p.SYS_NC_ROWINFO$,'/PurchaseOrder/LineItems/LineItem/Description'))) d
But I want to retreive it from "XDBPO_LINEITEM_TYPE".
Is this possible?
Can someone help me please?
Thanks in advance.
Jay#1. If you had taken the time to read some of the other posts in the forum all of the answers you needed were all there..
#2. As PM's we are not expected to spend a lot of time dealing with the forums. In general we are expected only to step in and answer the questions that are not easily answered by carefully reading existing posts or deal with cases were the wrong answer is supplied.
#3. I'm technically on vacation, and posted to that effect last week, so pushing for an answer is not at all appreciated...
#4. The problem is extremely simple, at least as stated in your simple example.

Creating XML from Relational Tables using java
I would like to create an XML document by querying relational tables in java
try {
connection = getConnection();
final String qryStr = "select XMLElement( foo, 'bar' ) from dual";
final OracleXMLQuery qry = new OracleXMLQuery(connection, qryStr);
final String xmlString = qry.getXMLString();
I would expect this to give the following result that I get from running the statement in SQL Developer
select XMLElement( foo, 'bar' ) from dual
<FOO>bar</FOO>
Instead I get
<?xml version = '1.0'?>
<ERROR>oracle.xml.sql.OracleXMLSQLException: Character ')' is not allowed in an XML tag name.</ERROR>
Is this the correct way to go about this?Is this the correct way to go about this?
Not really.
OracleXMLQuery class is the Java-side implementation of DBMS_XMLQUERY APIs.
It's mostly designed to generate a canonical XML document out of a SQL query.
Assuming a query like "SELECT col1, col2 FROM my_table", the resulting XML should appear like this :
<ROWSET>
<ROW>
<COL1>123</COL1>
<COL2>ABC</COL2>
</ROW>
<ROW>
<COL1>456</COL1>
<COL2>XYZ</COL2>
</ROW>
</ROWSET>
So in your test, since the resulting column is not aliased (XMLElement), you're actually trying to generate something like this :
<ROWSET>
<ROW>
<XMLELEMENT(FOO,'BAR')>
<FOO>bar</FOO>
</XMLELEMENT(FOO,'BAR')>
</ROW>
<ROWSET>
which of course is invalid, hence the error message.
If you want to generate only <FOO>bar</FOO> as output, just use a regular PreparedStatement with your query and access the document in the ResultSet with the proper getter.
