Fetch XML data stored in database table column dynamically

Hi All,
I am working as a SQL guy but never worked on XML in SQlbefore.
During some project work , we need to fetch value from xml stored in database column.
Problem is rowsof xml column arebit different and have different values.
Could anybody help me to build something dynamic to fetch all values from each row .
My data look like:
TEXT

Please post a concise and complete example. Include table DDL and sample data INSERT statements.
Cause the solution depends on your actual structure. Otherwise take a look at the
nodes() method.
E.g.
DECLARE @Sample TABLE
ID INT IDENTITY ,
Data XML
INSERT INTO @Sample
( Data )
VALUES ( '<RiskEndorsement><ExistingExposureSplitLimitsChange><NewRiskLimitSeq>536504</NewRiskLimitSeq><EffDate>11/1/2011</EffDate></ExistingExposureSplitLimitsChange></RiskEndorsement> ' ),

Hi Manu
Im not quite sure what your question is?
Are you trying to load data to the database or
Are you trying to retrieve data from the database ?
Either way this forum is meant for XML Publisher or BI Publisher issues not just XSL ... you might be better asking on the XML forum.

Capture XML data payload into database table (Oracle EBS R12)

Hi All,
We have a XML Publisher report which generates output in PDF format. We want to capture the XML data payload generated by this report and put it into a DB table once the PDF is generated.
This report is generated through Oracle EBS R12 and XML Payload is stored by oracle by default in $APPLCSF/out directory.
Any pointers would be helpful
br

Couple of options, this one is probably the easiest without knowing other requirements (e.g., do you have to store the output as XML, or do you just the data available so you can output in XML later?).
Capture the SQL statement that generates the output in the first place. If you have that statement, you can insert into some table using the select statement. Once you have the report data (and you can tag that particular set of data with a job ID, timestamp, whatever, in case you need to store it and distinguish it from other reports down the road), you can generate XML output using the PL/SQL built-in DBMS_XMLGEN.
Is that what you are looking for?

How to query XML data stored in a CLOB column

I don't know XMLDB, so I have a dumb question about querying XML data which is saved as CLOB in a table.
I have a table (OLAP_AW_PRC), with a CLOB column - AW_XML_TMPL_VAL
This column contains this xml data - [click here|http://www.nasar.net/aw.xml]
Now I want to query the data using the xml tags - like returning the name of AW. This is where I am having trouble, how to query the data from AW_XML_TMPL_VAL clob column.
The following query generates error:
ORA-31011: XML parsing failed.
ORA-19202: Error occurred in XML processing
LPX-00229: input source is empty
SELECT
extractValue(value(x), '/AW/LongName') as "AWNAME"
from
OLAP_AW_PRC,
table(xmlsequence(extract (xmltype(AW_XML_TMPL_VAL), '/AWXML/AWXML.content/Create/ActiveObject/AW'))) x
where
extractValue(value(x) , '/AW/Name') = 'OMCR4'
- Nasar

Mark,
Thanks. This is exactly what I was looking for.
After doing @Name in both places (SELECT and WHERE clause) it worked.
Now I have one more question.
There are multiple DIMENSION tags in my xml, and I want to see the NAME attribute values for all of those DIMENSIONs. The following query returns
ORA-19025: EXTRACTVALUE returns value of only one node.
Cause: Given XPath points to more than one node.
Action: Rewrite the query so that exactly one node is returned.
SELECT
extractValue(value(x), '/AW/@Name') as "AW",
extractValue(value(x), '/AW/Dimension/@Name') as "DIMENSIONS"
from
OLAP_AW_PRC,
table(xmlsequence(extract (xmltype(AW_XML_TMPL_VAL), '/AWXML/AWXML.content/Create/ActiveObject/AW'))) x
where
extractValue(value(x) , '/AW/@Name') = 'OMCR4'

Mapping XML data to relational database tables

I'm writing an application that has two parts: the client part generates XML documents and sends them across the network to a server part, which parses the XML, maps the XML to various RDBMS tables and stores the data in the RDBMS.
I've got everything working using SAX, but now any change I make to the XML schema and/or the RDBMS table structures in the future will mean some serious code changes.
Has anyone worked with this scenario and developed a better method of handling this mapping? All the previous efforts in this area seem to be RDBMS to XML, which is of no use to me.
If you had to do this this, how would you approach it? I'm using XML for ease of reading, as the client has code to allow for documents to be written to the disk if no connection to the server is available, and the server does the same if no database connection is available.
Thanks in advance ...
cheers,
mark

OK, to reply to my own posting for future reference, I've found an open source project called Osage at http://sourceforge.net that does what I need. I'm looking at it now and can't say if it's everything I want, but it seems likely to fit the bil.

Trying to Insert an XML Element into XML data stored in CLOB column

Hi all,
My ORACLE DB version is:

('CORE 11.2.0.2.0 Production');
('TNS for Linux: Version 11.2.0.2.0 - Production');
('NLSRTL Version 11.2.0.2.0 - Production');
I have this XML data stored in a CLOB column:
<Activity>
     <Changes>
     </Changes>
     <Inserts>
     </Inserts>
     <Definition>
     </Definition>

I am in need of some assistance in creating an update that will insert another <Activity>SomeGUID</Activity> into the <Spawned> parent.
Any help is greatly appreciated.
Thanks.

See XML updating functions : http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb04cre.htm#i1032611
For example :
UPDATE my_table t
SET t.my_clob =
      XMLSerialize(document
        insertChildXML(
          XMLParse(document t.my_clob)
        , '/Activity/Spawned'
        , 'Activity'
        , XMLElement("Activity", 'Some GUID')
WHERE ...
;Although it works, there's overhead introduced by parsing the CLOB, then serializing again.
Is there any chance you can change the CLOB to SECUREFILE binary XMLType storage instead?
You would then be able to benefit from optimized piecewise update of the XML and improved storage.

Read table data and fetch file from path specified in table column

Hi,
I have a situation where file path information is stored in database table along with other columns - I need to read data from SQL Server table row by row, go to the path identified by the record, check for existance of the file - if the file is available copy it to a staging area, then read the next record. Repeat this process until the last record is fetched from the table. At the end, zip all the files found and FTP to a different location. If the file is not found in the path specified, write the database record to a seperate text file.
At end of the process, send an email with records for which files were not found at specified location.
Thanks

Hi,
That is not complex to solve at ODI.
Try the following.
1) Create a package
2) create a variable to receive the path as parameter and drag and drop it at package as "Declared"
3) drag and drop the ODI Tool "odiFileMove" using and let the variable as patch at ODI Tool parameter.
Use the parameters -ACTION=MOVE -TIMEOUT=100 and -NOFILE_ERROR=NO (take a look at ODI Toos Reference for other parameters)
3) Create a "KO" (error) flow to write the variable at a text file. That will allow the process knows what file is missing
4) generate a scenario of this package
5) create a procedure
6) at first step, put the query from SQL Server (set the Logical Schema to the right connection)
7) at Target tab, put the call to the scenario generated using the returned value from query parameter. Plus, let the -SYNC_MODE=1. That will call one scenario by time.
8) create a new step to zip the files at stage directory
9) create a step to make the ftp
10) create a step to mail the txt generated with files not founded. If you wish, you can make a validation on the file to see if is necessary to send the mail, it means, if there is any file missing.
Does it help you?

When / why use XML to store data instead of database table ?

Hi All,
I still not use XML much in applications and don't know much about its utilization.
I read here and there about storing data as XML instead of into database tables.
- could any body please tell me when / why use XML to store data instead of database table ?
e.g : store inventory per warehouse in XML format. ?
- What is the other cases or reasons of extracting database records into XML or vice versa ?
- is there any good pdf on this ?
Thank you for your help,
xtanto

It depends entirely what you want to accomplish with the 'XML in the database'. There are basically 3 independent methods: As CLOB, as XMLType views or as native XMLType 'columns'
Each method has advantages and disadvantages, especially in the performance vs purpose tradeoff.
The Oracled Press book "Oracle Database 10g XML & SQL Design, Build, & Manage XML Applications in Java, C, C++, & PL/SQL" is highly recommended for anyone interested in Oracle and XML. http://books.mcgraw-hill.com/getbook.php?isbn=0072229527&template=oraclepress

RESULT
*LONDON*
Does the OAVendorLocation really have a whitespace value?
If not then it's expected behaviour, you're trying to update a text() node that doesn't exist. In this case, the solution is to use appendChildXML to create the text() node, or update the whole element.
Is it your real document? Do you actually have some namespaces?

How to input data in a database table without knowing in advance table and column configurations

Hi,
I have a problem using LabVIEW for input data (manually) in a SQL database. I have about 40 tables in the database, each of them is related to a specific engine component. I need to create a user interface (maybe visualizing the table with a table control) where the users can insert data in the database table fields. Could someone give me some suggestion on how to do it?
Using the DB tools insert data.vi I need to know in advance the column configuration of the table, but in my database each table has its own structure! So do I have to create 40 different masks, one for every different table?
Thanks in advance.
Michela

I have not actually used the LV SQL Toolkit, but I will try and offer high level ideas :-)
when you have retrieved the construction data for a table, you should be able to use array and cluster indexing to aquire the names of the fieds, enough to create a labelled table on the LV Front panel.
After completing a new entry you can INSERT the entry into the database using the same data.
Is the SQL toolkit an additional purchase, or included in newer versions as standard? If you post a sample of the cluster/array that you retrieve, I could give you a sample VI to give you some pointers in creating the User Interface table

Read xml-structure from a xml-document stored in a xmltype-column?

Hello,
I have several xml-documents stored in a table with a xmltype-column.
Is it possible to read the structure of one xml-document? I need to know what data are exists in the xml-documents.
I had read some hours here, but I dont find a suitable solution for that.
To make a example, what I need:
I have stored the following xml-document in the table:
<?xml version = '1.0'?>
<ROWSET>
<ROW num="6">
<EMPLOYEE_ID>105</EMPLOYEE_ID>
<FIRST_NAME>David</FIRST_NAME>
<LAST_NAME>Austin</LAST_NAME>
<EMAIL>DAUSTIN</EMAIL>
<PHONE_NUMBER>590.423.4569</PHONE_NUMBER>
<HIRE_DATE>6/25/1997 0:0:0</HIRE_DATE>
<JOB_ID>IT_PROG</JOB_ID>
<SALARY>4800</SALARY>
<MANAGER_ID>103</MANAGER_ID>
<DEPARTMENT_ID>60</DEPARTMENT_ID>
</ROW>
</ROWSET>
I need to return the following:
ROWSET
...ROW
......EMPLOYEE NUMBER
......FIRST_NAME VARCHAR2
......DEPARTMENT_ID NUMBER

Hi,
I was on a wrong way. The datatype is not stored in xml, this was a mistake from me.
I needed something to printout some values from a xml-file. This xml-file was generated bei MS Excel. The data are in /Workbook/Worksheet/Table/Cell and I didnt know how to access it.
I write for that the following:
DECLARE
v_xml XMLType;
v_doc dbms_xmldom.DOMDocument;
v_node dbms_xmldom.DOMNode;
type t_values is table of varchar2(2000) index by binary_integer;
v_values t_values;
type t_table is table of t_values index by binary_integer;
v_table t_table;
procedure node_output (v_node in out dbms_xmldom.DOMNode)
is
v_nodelist1 DBMS_XMLDOM.DOMNodeList;
v_nodelist2 DBMS_XMLDOM.DOMNodeList;
v_anzahlnodes number;
v_anzahlrows number;
v_node_c dbms_xmldom.DOMNode;
v_xmlmitarbeiterid number;
begin
v_nodelist1 := dbms_xmldom.GETCHILDNODES(v_node);
v_anzahlrows := DBMS_XMLDOM.GETLENGTH(v_nodelist1);
if v_anzahlrows = 0 or DBMS_XMLDOM.GETNODENAME(v_node) = 'Table'
then
if v_anzahlrows > 0
then
for i1 in 0..v_anzahlrows - 1
loop
v_node := dbms_xmldom.Item(v_nodelist1,i1);
v_nodelist2 := dbms_xmldom.GETCHILDNODES(v_node);
v_anzahlnodes := DBMS_XMLDOM.GETLENGTH(v_nodelist2);
for i2 in 0..v_anzahlnodes - 1
loop
v_node := dbms_xmldom.Item(v_nodelist2,i2);
v_node_c := dbms_xmldom.GETFIRSTCHILD(v_node);
v_node_c := dbms_xmldom.GETFIRSTCHILD(v_node_c);
v_values(i2) := DBMS_XMLDOM.GETNODEVALUE(v_node_c);
end loop;
v_table(i1) := v_values;
end loop;
for i1 in 1..v_anzahlrows - 1
loop
select SEQ_XMLMITARBEITER.nextval into v_xmlmitarbeiterid from dual;
for i2 in 1..v_table(i1).count - 1
loop
dbms_output.put_line(v_table(i1)(i2));
end loop;
end loop;
end if;
else
v_node := dbms_xmldom.GETFIRSTCHILD(v_node);
for i in 0..v_anzahlrows - 1
loop
v_node := dbms_xmldom.Item(v_nodelist1,i);
node_output(v_node);
end loop;
end if;
end;
BEGIN
select inhalt into v_xml FROM xmlimport WHERE name = 'F23973/mitarbeiter.xml';
v_doc := dbms_xmldom.newDOMDocument(v_xml);
v_node:= dbms_xmldom.makeNode(dbms_xmldom.getDocumentElement(v_doc));
node_output(v_node);
END;
This gives me all data from a xml-Excel-file. Is there a better way to do that? I have Oracle 10.2.

Mark

Fetch XML data from CLOB

Hi,
I'm very new in Oracle. I have DB running on oracle 9i. On production DB one tablespace have CLOB datatype and this CLOB field have all techinal stuff stored in XML format. How DO I fetch this info?
select info from infotbl; showing all the XML junk.
what is the batter way to fetch XML data properly

Difficult to give the exact answer without knowing which node repeats..
Howver it will be something like this
select extractValue(value(x),'/RepeatingNode/NonRepatingNode/NonRepeatingNode)
from TABLE, table(xmlsequence(extract(xmltype(clob),'/Root/Node/RepeatingNode')))) x
