Loading an XML file into the table without creating a directory .

Hi,
I wanted to load an XML file into a table column . But I should not create a directory in the server and placing the XML file there and giving the path in the insert query. Can anybody help me here?
Thanks in advance.

You could write a java stored procedure that retrieves the file into a clob. Wrap that in a function call and use it in your insert statement.
This solution require read privileges granted by sys and is therefore only feasible if the top-level directory/directories are known or you get read-access to everything.

How to load a XML file into a table

Hi,
I've been working on Oracle for many years but for the first time I was asked to load a XML file into a table.
As an example, I've found this on the web, but it doesn't work
Can someone tell me why? I hoped this example could help me.
the file acct.xml is this:
<?xml version="1.0"?>
<ACCOUNT_HEADER_ACK>
<HEADER>
<STATUS_CODE>100</STATUS_CODE>
<STATUS_REMARKS>check</STATUS_REMARKS>
</HEADER>
<DETAILS>
<DETAIL>
<SEGMENT_NUMBER>2</SEGMENT_NUMBER>
<REMARKS>rp polytechnic</REMARKS>
</DETAIL>
<DETAIL>
<SEGMENT_NUMBER>3</SEGMENT_NUMBER>
<REMARKS>rp polytechnic administration</REMARKS>
</DETAIL>
<DETAIL>
<SEGMENT_NUMBER>4</SEGMENT_NUMBER>
<REMARKS>rp polytechnic finance</REMARKS>
</DETAIL>
<DETAIL>
<SEGMENT_NUMBER>5</SEGMENT_NUMBER>
<REMARKS>rp polytechnic logistics</REMARKS>
</DETAIL>
</DETAILS>
<HEADER>
<STATUS_CODE>500</STATUS_CODE>
<STATUS_REMARKS>process exception</STATUS_REMARKS>
</HEADER>
<DETAILS>
<DETAIL>
<SEGMENT_NUMBER>20</SEGMENT_NUMBER>
<REMARKS> base polytechnic</REMARKS>

<DETAIL>
<SEGMENT_NUMBER>30</SEGMENT_NUMBER>
</DETAIL>

</DETAIL>
<DETAIL>
<SEGMENT_NUMBER>50</SEGMENT_NUMBER>
<REMARKS> base polytechnic logistics</REMARKS>
</DETAIL>
</DETAILS>
</ACCOUNT_HEADER_ACK>
For the two tags HEADER and DETAILS I have the table:
create table xxrp_acct_details(
status_code number,
status_remarks varchar2(100),
segment_number number,
remarks varchar2(100)
before I've created a
create directory test_dir as 'c:\esterno'; -- where I have my acct.xml
and after, can you give me a script for loading data by using XMLTABLE?
I've tried this but it doesn't work:
DECLARE
acct_doc xmltype := xmltype( bfilename('TEST_DIR','acct.xml'), nls_charset_id('AL32UTF8') );
BEGIN
insert into xxrp_acct_details (status_code, status_remarks, segment_number, remarks)
select x1.status_code,
        x1.status_remarks,
        x2.segment_number,
        x2.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns header_no      for ordinality,
          status_code    number        path 'STATUS_CODE',
          status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'$d/ACCOUNT_HEADER_ACK/DETAILS[$hn]/DETAIL'
passing acct_doc as "d",
          x1.header_no as "hn"
columns segment_number number        path 'SEGMENT_NUMBER',
          remarks        varchar2(100) path 'REMARKS'
) x2
END;
This should allow me to get something like this:
select * from xxrp_acct_details;
Statuscode status remarks segement remarks
100 check 2 rp polytechnic
100 check 3 rp polytechnic administration
100 check 4 rp polytechnic finance
100 check 5 rp polytechnic logistics
500 process exception 20 base polytechnic
500 process exception 30
500 process exception 40 base polytechnic finance
500 process exception 50 base polytechnic logistics
but I get:
Error report:

and if I try to change the script without using the column HEADER_NO to keep track of the header rank inside the document:

My oracle version is 10gR2 Express Edition
I do need a script for loading xml files into a table as soon as possible, Give me please a simple example for understanding and that works on 10gR2 Express Edition
Thanks in advance!

The reason your first SQL statement
select x1.status_code,
        x1.status_remarks,
        x2.segment_number,
        x2.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns header_no      for ordinality,
          status_code    number        path 'STATUS_CODE',
          status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'$d/ACCOUNT_HEADER_ACK/DETAILS[$hn]/DETAIL'
passing acct_doc as "d",
          x1.header_no as "hn"
columns segment_number number        path 'SEGMENT_NUMBER',
          remarks        varchar2(100) path 'REMARKS'
) x2
returns the error you noticed
PL/SQL: ORA-00932: inconsistent datatypes: expected - got NUMBER
is because Oracle is expecting XML to be passed in. At the moment I forget if it requires a certain format or not, but it is simply expecting the value to be wrapped in simple XML.
Your query actually runs as is on 11.1 as Oracle changed how that functionality worked when 11.1 was released. Your query runs slowly, but it does run.
As you are dealing with groups, is there any way the input XML can be modified to be like
<ACCOUNT_HEADER_ACK>
<ACCOUNT_GROUP>
<HEADER>....</HEADER>
<DETAILS>....</DETAILS>
</ACCOUNT_GROUP>
<ACCOUNT_GROUP>
<HEADER>....</HEADER>
<DETAILS>....</DETAILS>
</ACCOUNT_GROUP>
</ACCOUNT_HEADER_ACK>
so that it is easier to associate a HEADER/DETAILS combination? If so, it would make parsing the XML much easier.
Assuming the answer is no, here is one hack to accomplish your goal
select x1.status_code,
        x1.status_remarks,
        x3.segment_number,
        x3.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns header_no      for ordinality,
          status_code    number        path 'STATUS_CODE',
          status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'$d/ACCOUNT_HEADER_ACK/DETAILS'
passing acct_doc as "d",
columns detail_no      for ordinality,
          detail_xml     xmltype       path 'DETAIL'
) x2,
xmltable(
'DETAIL'
passing x2.detail_xml
columns segment_number number        path 'SEGMENT_NUMBER',
          remarks        varchar2(100) path 'REMARKS') x3
WHERE x1.header_no = x2.detail_no;
This follows the approach you started with. Table x1 creates a row for each HEADER node and table x2 creates a row for each DETAILS node. It assumes there is always a one and only one association between the two. I use table x3, which is joined to x2, to parse the many DETAIL nodes. The WHERE clause then joins each header row to the corresponding details row and produces the eight rows you are seeking.
There is another approach that I know of, and that would be using XQuery within the XMLTable. It should require using only one XMLTable but I would have to spend some time coming up with that solution and I can't recall whether restrictions exist in 10gR2 Express Edition compared to what can run in 10.2 Enterprise Edition for XQuery.

Not a perfectly framed question. How do you want to load the XML file? Hoping you want to parse the xml file and load it into a table you can do this.
This is the xml file
karthick% cat emp_details.xml
<?xml version="1.0"?>
<ROWSET>
<ROW>
<EMPNO>7782</EMPNO>
<ENAME>CLARK</ENAME>
<JOB>MANAGER</JOB>
<MGR>7839</MGR>
<HIREDATE>09-JUN-1981</HIREDATE>
<SAL>2450</SAL>
<COM>0</COM>

</ROW>
<ROW>
<EMPNO>7839</EMPNO>
<ENAME>KING</ENAME>

<HIREDATE>17-NOV-1981</HIREDATE>
<SAL>5000</SAL>
<COM>0</COM>
<DEPTNO>10</DEPTNO>
</ROW>
</ROWSET>
You can write a query like this.
SQL> select *
2    from xmltable
3         (
4            '/ROWSET/ROW' passing xmltype
5            (

How to load a XML file into the database

Hi,
I've always only loaded data into the database by using SQL-Loader and the data format was Excel or ASCII
Now I have to load a XML.
How can I do?
The company where I work has Oracle vers. 8i (don't laugh, please)
Thanks in advance!

Hi,
Tough job especially if the XML data is complex. The have been some similar question in the forum:
Using SQL Loader to load an XML File -- use 1 field's data for many records
SQL Loader to upload XML file
Hope they help.

Performance problems loading an XML file into oracle database

Hello ODI Guru's,
I am trying to load and XML file into the database after doing simple business validations. But the interface takes hours to complete.
1. The XML files are large in size >200 Mb. We have an XSD file for the schema definition instead of a DTD.
2. We used the external database feature for loading these files in database.
The following configuration was used in the XML Data Server:
jdbc:snps:xml?f=D:\CustomerMasterData1\CustomerMasterInitialLoad1.xml&d=D:\CustomerMasterData1\CustomerMasterInitialLoad1.xsd&re=initialLoad&s=CM&db_props=oracle&ro=true
3. Now we reverse engineer the XML files and created models using ODI Designer
4. Similar thing was done for the target i.e. an Oracle database table as well.
5. Next we created a simple interface with one-to-one mapping from the XSD schema to the Oracle database table and executed the interface. This execution takes more than one hour to complete.
6. We are running ODI client on Windows XP Professional SP2.
7. The Oracle database server(Oracle 10g 10.2.0.3) for the target schema as well as the ODI master and work repositories are on the same machine.
8. I tried changing the following properties but it is not making much visible difference:
use_prepared_statements=Y
use_batch_update=Y
batch_update_size=510
commit_periodically=Y
num_inserts_before_commit=30000
I have another problem that when I set batch_update_size to value greater that 510 I get the following error:
java.sql.SQLException: class org.xml.sax.SAXException
class java.lang.ArrayIndexOutOfBoundsException said -32413
at com.sunopsis.jdbc.driver.xml.v.a(v.java)
The main concern is why should the interface taking so long to execute.
Please send suggestions to resolve the problem.
Thanks in advance,
Best Regards,
Nikunj

Approximately how many rows are you trying to insert?
One of the techniques which I found improved performance for this scenario was to extract from the xml to a flat file, then to use SQL*LOADER or external tables to load the data into Oracle.

Upload an XML file into the Internal table

Hi Guys,
I want to know, how to upload an xml file into the Internal table through ABAP programming

you just wanted to load the xml file into internal table (as a table of binary strings)or load the xml data mapped to itab row columns
for the first one you can simply use gui_upload
and for the second one you need to load the xml file using gui_upload and use XLST program to transform into an itab

Loading XML files into Database table

Loading XML files into Database table
Hi I have some XML files say 100 files in a virtual directory created using "Create or replace directory command" and those files need to be loaded into a table having a column of XMLTYPE. 1)How to load that using Oracle provided procedures/packages

Check out the Oracle XDB Developer's Guide, Chapter 3. There is an example of using BFileName function to load the xml files from a directory object created using create or replace directory. It works really well.

Importing data- using xml file into HANA Table

Hi,
We are using (HDB STUDIO ) - revision 60.......
Is it possible to import data using XML file into HANA table (Master,Fact tables)?
(Without using any intermediate adapters for conversion of data.....)
Can any one suggest us........
Thank you.

Hi user450616
I am a bit confused about what you are trying to achieve.
Are you:
1. importing a CSV file into APEX
2. adding an extra column to the Oracle Table
3. populating the extra column with the CSV filename?
Let us know if this is what you are trying to do.
Cheers,

Inserting XML file into a Table

Hello,
Can someone provide me with a sample code to load xml files into a table. Thanks a lot.
Rajeesh

Keeping my fingers crossed that this quote from "Building XML Oracle Applications" by Steve Muench (O'Reilly & Associates, 2000, ISBN 1-56592-691-9) falls into the "fair use" category, and that you want it in PL/SQL, here is a procedure:
PROCEDURE insertXMLFile
(dir VARCHAR2, file VARCHAR2, name VARCHAR2 := NULL) IS
theBFile BFILE;
theCLob CLOB;
theDocName VARCHAR2(200) := NVL(name,file);
BEGIN
-- (1) Insert a new row into xml_documents with an empty CLOB, and
-- (2) Retrieve the empty CLOB into a variable with RETURNING.INTO
INSERT INTO stylesheets(docname,sheet) VALUES(theDocName,empty_clob( ))
RETURNING sheet INTO theCLob;
-- (3) Get a BFile handle to the external file
theBFile := BFileName(dir,file);
-- (4) Open the file
dbms_lob.fileOpen(theBFile);
-- (5) Copy the contents of the BFile into the empty CLOB
dbms_lob.loadFromFile(dest_lob => theCLob, src_lob => theBFile, amount => dbms_lob.getLength(theBFile));
-- (6) Close the file and commit
dbms_lob.fileClose(theBFile);
COMMIT;

Hi Sarvesh,
The pdf has details of ABAP mapping. The example given almost matches the xml file you want to be converted.

Load an XML file into table(s)

Hi ,
I have to load data from an xml file into an Oracle DB but I never used this king of process before. The purpose is to use as much as possible Oracle standard features ( stored procedures , functions , API's ).
Can someone explain me in simple explanations how to do it ? Thanks in advance for your help.
The XML must not be stored in the database , only the final tables
Values can be inserted , updated , or deleted from the final tables
Here are the versions of the tools I am using :
Oracle RDBMS : 10.2.0.4.0
Oracle Applications : 11.5.10.2
Toad : 9.5.0.31
SQL Plus : 8.0.6.0.0
The header of the xsd :
<?xml version="1.0" encoding="windows-1252" ?>
- 
- <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3schools.com" targetNamespace="http://www.w3schools.com" elementFormDefault="qualified">
An extract of the xml :
<?xml version="1.0" encoding="windows-1252" ?>
- <GraydonBeDialogue>
<TransactionCode>RTB</TransactionCode>
- <Table ClassTable="Country">
- <TableEntry>
<TableLanguage>N</TableLanguage>
<TableCode>AD</TableCode>
<TableValue>Andorra</TableValue>
</TableEntry>
- <TableEntry>
<TableLanguage>N</TableLanguage>
<TableCode>AE</TableCode>
<TableValue>Verenigde Arabische Emiraten</TableValue>
</TableEntry>
</Table>
- <Table ClassTable="Summons">
- <TableEntry>
<TableLanguage>N</TableLanguage>
<TableCode>D</TableCode>
<TableValue>De dagvaarding is het gevolg</TableValue>
</TableEntry>
- <TableEntry>
<TableLanguage>N</TableLanguage>
<TableCode>S</TableCode>
<TableValue>Doorgehaald bij de arbeidsrechtbank</TableValue>
</TableEntry>
</Table>
</GraydonBeDialogue>
The result I would have :
Two tables ( Country and Summons ) , each containing 3 columns ( TableLanguage , TableCode , TableValue ) :
Table Country : TableLanguage TableCode TableValue
N AD Andorra
N AE Verenigde Arabische Emiraten
Table Summons : TableLanguage TableCode TableValue
N D De dagvaarding is het gevolg
N S Doorgehaald bij de arbeidsrechtbank

for table Country
create table Country as
with t as (
    select
    xmltype (
        '<?xml version="1.0" encoding="windows-1252" ?>
<GraydonBeDialogue>
     <TransactionCode>RTB</TransactionCode>

               <TableEntry>

                    <TableCode>AD</TableCode>
                    <TableValue>Andorra</TableValue>
               </TableEntry>
               <TableEntry>
                    <TableLanguage>N</TableLanguage>
                    <TableCode>AE</TableCode>
                    <TableValue>Verenigde Arabische Emiraten</TableValue>
               </TableEntry>
          </Table>
          <Table ClassTable="Summons">
               <TableEntry>

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.

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
