Loading XML file into non-XML table(s)

HI Gentlemen,
I successfully registered my schema and generated an xml-based table and a TYPE. However, I do not have the table that would correspond to this TYPE. How do I get to it? How can I use FTP or HTTP protocol to load actual data from the corresponding .xml file into this table?
Thanks in advance, kind regards from
Miklos HERBOLY

You need to include the XML schema location information in the XML documents to point to the registered XML schema.
For example,
If you register an XML schema to XML DB with "http://www.example.com/po.xsd"
In the XML document, the xml schema location can be:
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.example.com/po.xsd http://www.example.com/po.xsd">
For more information, you can check the example in the following page:

Best,

Need to Load data in XML file into multiple Oracle tables

Experts
I want to load data that is stored at XML file into multiple Oracle table using plsql.
I am novice in this area.Kindly explain in depth or step by step so that i can achive this.
Thanks in advnace.

Hi,
extract your xml and then you can use insert all clause.
here's very small example on 10.2.0.1.0
SQL> create table table1(id number,val varchar2(10));
Table created.
SQL> create table table2(id number,val varchar2(10));
Table created.
SQL> insert all
2 into table1 values(id,val)
3 into table2 values(id2,val2)
4 select extractValue(x.col,'/a/id1') id
5 ,extractValue(x.col,'/a/value') val
6 ,extractValue(x.col,'/a/value2') val2
7 ,extractValue(x.col,'/a/id2') id2
8 from (select xmltype('<a><id1>1</id1><value>a</value><id2>2</id2><value2>b</value2></a>') col from dual) x;
2 rows created.
SQL> select * from table1;
 ID VAL
 1 a
SQL> select * from table2;
 ID VAL

Use XSU to store in multiple tables.
"XSU can only store data in a single table. You can store XML across tables, however, by using the Oracle XSLT processor to transform a document into multiple documents and inserting them separately. You can also define views over multiple tables and perform insertions into the views. If a view is non-updatable (because of complex joins), then you can use INSTEAD OF triggers over the views to perform the inserts."

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

Load XML file into oracle xml buffer

Hi guys,
I'm a starter in Oracle XML Development, I wander how I can load a xml file into oracle xml buffer(xmlctx* document) through programming with c++ in visual studio.
When I use orastream structure, it compiled failed.
Thank you very much!

try this
LOAD DATA
INFILE '/home/oraread/'
INTO TABLE xmlloadtable
(id,
file_name filler,
data_xml lobfile(file_name) terminated by eof
)you can add the file_name field as a column to your table between the id and xml column and remove the filler word in the .ldr file if you need to keep the name of the file

Collect data from a dynamic XML file into multiple internal tables

I need to convert the XML file into multiple internal tables. I tried many links and posts in SDN but still was facing difficulty in achieving this. Can some one tell me where I am going wrong.
My XML file is of the following type.It is very complex and the dynamice.
The following tags occur more than once in the XML file. The "I" and "L" tags and its child tags can occur ones or more than once for each XML file and it is not constant. i.e in one file they can occur 1 time and in another they can occur 100 times.
"I" and "L" are child tags of <C>

 <J>10</J>
 <K>EN</K>

<L>
 <J>20</J>
 <N>BB</N>
</L>
Tags <C> and <F> occur only ones for each XML file. <C> is the child tag of "A" and "F" is the child tag of <C>.
I need to collect <D>, <E> in one internal table ITAB.
I need to collect <G>, <H> in one internal table JTAB.
I need to collect <J>, <K> in one internal table KTAB.
I need to collect <J>, <N> in one internal table PTAB.
Below is the complete XML file.
?xml version="1.0" encoding="iso-8859-1" ?>
<A>
 
 <C>
 <D>RED</D>
 <E>999</E>
 <F>
 <G>TRACK</G>
 <H>PACK</H>
 </F>
 
 <J>10</J>
 <K>EN</K>
 
 
 <J>20</J>

 <J>20</J>
 <N>BB</N>
 </L>
 <L>
 <J>30</J>
 <N>CC</N>
 </L>
 </C>
</A>
With the help of SDN I am able to gather the values of <D> <E> in one internal table.
Now if I need to gather
<G>, <H> in one internal table JTAB.
<J>, <K> in one internal table KTAB.
<J>, <N> in one internal table PTAB.
I am unable to do. I am following XSLT transformation method. If some one has some suggestions. Please help.

Hi Rammohan,
Thanks for the effort!
But I don't need to use GUI upload because my functionality does not require to fetch data from presentation server.
Moreover, the split command advised by you contains separate fields...f1, f2, f3... and I cannot use it because I have 164 fields. I will have to split into 164 fields and assign the values back to 164 fields in the work area/header line.
Moreover I have about 10 such work areas. so the effort would be ten times the above effort! I want to avoid this! Please help!
I would be very grateful if you could provide an alternative solution.
Thanks once again,
Best Regards,

Xml data into non-xml database.. solution anyone?

Hi,
My current project requires me to store the client's data on our servers. We're using Oracle9i. Daily, I will download the client's data for that day and load it into our database. My problem is that the data file is not a flat file so I can't use sql*loader to load the data. Instead, the data file is an xml file. What is the best way to load xml data into a non-xml database? Are there any tools similar to sql*Loader that will load xml data into non-xml database? Is it the best solution for the client to give me an XML dump of their data to load into our database, or should I request a flat file? My last resort would be to write some sort of a script to parse the xml data into a flat file, and then run it through sql*loader. Is this the best solution? One thing to note is that these files could be very large.
Thanks in advance.

I assume that just putting the XML file into an
extremely large VARCHAR field is not what you want.
Instead, you want to extract data elements from the
XML and write them to columns in a table in your
database. Right?Yes. Your assumption is correct.
It sounds like you already have a script that loads a
flat file into your database. In that case I would
write an XSL transformation that converts the client's
XML into a correctly-formatted flat file.Thank you. I'll look into that. Other suggestions are welcome.

How to upload XML file into the internal table in Webdynpro ABAP ?

Hi Friends,
I am not able to upload the XML file into ABAP,can you please help me in solving this issue with the help of source code.
Regards
Dinesh

Hi Dinesh,
Try go through this program which I had developed earlier. It takes as input an XML file and then breaks it down into name-value pairs of an intrnal table. You need to pass an XML file as input to this program. (I had hard coded the path for my XML file in it. You need to replace it with 1 of your own or you can just delete it and use the browse button to selet the file on your PC)

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

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:
ORA-19025: EXTRACTVALUE returns value of only one node
Can anyone help me 4 this issue-How to extract multiple records from the XML file inthis manner(from PL/SQL without using JAVA)
OR
If there is anyother way to do this please tell me?

SQL> SELECT EXTRACTVALUE (COLUMN_VALUE, '//name') NAME,
 EXTRACTVALUE (COLUMN_VALUE, '//age') age
FROM TABLE
 (XMLSEQUENCE
 (EXTRACT
 (XMLTYPE
 ('<Root>
 <Record>
 <name>RAM</name>
 <age>23</age>
 </Record>
 <Record>
 <name>SAM</name>
 <age>23</age>
 </Record>
 </Root>'
 '/Root/Record'
NAME AGE

Loading multiple files into a target table parallely

Hi
We are building an interface to load from flat files to an Oracle table. The input can be more than one files all of th same format. I have created a variable for the flat file data store. I have created 2 packages
In package 1
I have put odi file wait to trigger whenever files come into the directory . The list of files is written to a metadata table table. A procedure is triggered which picks a record from the metadata table and calls the scenario for calls package 2 by passing the selected record as parameter.
In package 2
The variable value is set to the parameter passed from package 1 procedure
The interface runs to load the flat file = to the variable value into the target table
Now if the directory has more than one flat file , the procedure in package 1 calls the package 2 scenario more than one times. This causes sequential load from each flat file to the target table. Is there a way wherein the multiple flat files can be loaded in parallel to the same target table? At this point ,I am not sure if this is possible as there is only one interface and one variable for the source file

As per your requirement , your process seems to be always continues like a loop[ reason being as you have mentiond - I dont want to wait for all files to come in. As soon as a file comes in the file has to be loaded. ] .
You can solve the issue of file capture using OdiFileWait to let you know when the files have arrived.
Tell me this what do you plan to when the File loading is complete, will that be in the same folder and when new files come will that update with the same name or different name , becuase irresptive of same file or different if the files are present in the same folder after loading into target , then we might do repetitive loading of files. Please tell me how do you plan to handle this.
When you have plan to use LKM file to sql , what is the average number of source records coming into each sample files. ?
Just to add to above question , what is the average numner of parallel loads you are expecting and what is the time interval between each paralled loading you are expecting.
