External Parser - XML to Pipe Delimited - Sql Loader BETTER DBMS_XMLSTORE

Hi All,
If I have got data in GIGs in a complex format.
Can Using an External Java based XML Parser to convert XML to Pipe Delimited FIle and then Using SQL Loader
BE BETTER THAN
Using XSL to convert to Oracle <ROWSET> <ROW> Format and using DBMS_XMLSTORE to load data into tables.
In terms of:
Performace
Scalability
Exception Handling
Regards....

Go to the {forum:id=34} forum and look at the second page of the XML DB FAQ Thread (stickied to the top of the posts). While it doesn't compare using external tools to parse XML and load via SQL*Loader, it does talk about better ways to load large amounts of XML into the DB. This is also a good thread on the subject too from that forum, {thread:id=1096784}

what modification is required in the script to read such xml...Kindly Help!!

And in what way does this relate to SQL and PL/SQL?
There is a demo of loading XML in Morgan's Library under SQL*Loader.
But as your question is off-topic here ... if the demo does not help you please continue this by starting a thread in the correct forum: Database General.

You will need to manually parse that CLOB and pull out the XML string itself from the response. That can be done via SUBSTR and INSTR looking for the first < and last > in what you showed at least. Updated from previous version to work properly with the xmlns="", which resets the default namespace back to the default value. The XPath was corrected to reflect proper prefix usage.

SQL-Loader and Pipes

I have to insert 300.000.000 datasets (generated dynamically by a seperate process) into an Oracle 8.1.6 database. I'd like to do this via SQL-Loader but since Linux (kernel 2.2 at least) supports only files up to 2Gigs and I don't have the necessary space on my machine to generate a large amount of ASCII files I'd like to ask whether there is a possibility to use an ordinary pipe in combination with SQL-Loader. I tried to use a named pipe but all my attempts failed.
I don't like to use Perl and the DBI module since this would be far so slow (would take about one week I guess).

External tables are accessible from SQL, which generally simplifies life if the data files are physically located on the database server since you don't have to coordinate a call to an external SQL*Loader script with other PL/SQL processing. Under the covers, external tables are normally just invoking SQL*Loader.
SQL*Loader is more appropriate if the data files are on a different server or if it is easier to call an executable rather than calling PL/SQL (i.e. if you have a batch file that runs on a server other than the database server that wants to FTP a data file from a FTP server and then load the data into Oracle).

XML Column from table extract to Pipe Delimited Text File

Hi,
I have an XML column with large data in a Table ( Source SQL server Database).
I was asked to extract XML column to .txt file using SSIS.
Is it possible to extract xml column with huge data to text file ?
when I tried, select XML column from Table in source , I noticed that Property of column is taken as [DT_NTEXT] . I Converted it to DT_TEXT as Ansi donot support DT_NTEXT.
Execution method was success but it failed due to trucation. so wondering is there a way to get XML column extracted to Pipe delimited text file?
Is it advisable to do this ? or IS It Valid to export XML in Pipe Delimited File ?
Please Kindly advice
thanks
kodi

Are you looking at shredding data within XML nodes and then importing it to text file or are you looking at exporting XML value as is? Also is SSIS a necessity?
If not, You can simply use T-SQL for this along with bcp for this. just use a query like
EXEC xp_cmdshell 'bcp "SELECT CAST(XMLColumn AS varchar(max)) AS Column FROM table" queryout <full file path> -c -S <ServerName> -T -t |'
provided you use trusted connection (windows authentication)
see
http://visakhm.blogspot.in/2013/10/bcp-out-custom-format-data-to-flat-file.html
If you want to shred the data use Xpath functions in the query as below

l_n dbms_xmldom.DOMNode;
l_nl dbms_xmldom.DOMNodeList;

SQL Loader versus External Table

If anyone has worked on external tables please let me know your views.

user637544 wrote:
for sqlldr i follow the following approach
1. truncate table
2. call sqlldr and load records in staging table
3. check for bad records
how do i tuncate, call external table and check bad records for external table.As part of the SQL*Loader control file you can tell it to truncate the table as part of the process before it loads in the data.
The key differences between SQL*Loader and External Tables are:
1. SQL*Loader is an external utility run from the o/s command line, whereas External tables are usable from within SQL and PL/SQL.
2. SQL*Loader can only load data up into the database, whereas External tables can allow you to read files and write files (10g onwards)
3. SQL*Loader has limited control on skipping rows etc. whereas External tables can be queried using SQL and has all the flexibility that SQL can offer.
4. SQL*Loader requires connection information to the database, whereas External tables are already part of the database
5. SQL*Loader can only change the source filename through dynamic o/s level scripts, whereas External tables can have the filename changed using an ALTER TABLE ... LOCATION ... command.
If you want to truncate your staging table before loading it with data from the external table, then you will just have to do that as a seperate step, because the external table is not associated with other tables. Simply truncate the other table and then query the data from the external table into the staging table.
External tables offer a lot more flexibility than using SQL*Loader.

Request: PL/SQL, External Table and SQL Loader

I see lately Questions asked in SQL and PL/SQL forum regarding SQL Loader and External Table are being moved to {forum:id=732}.
Being an PL/SQL developer for some time now i feel External Table (and if i may, SQL Loader and DBMS_DATAPUMP) are very much an integral part of a PL/SQL development and the question related to these topics are well suited in SQL and PL/SQL forum. Even in SQL and PL/SQL FAQ we have exclusive content that discuss on these topics {message:id=9360007}
So i would like to request the moderators to consider not moving such questions out of the SQL and PL/SQL forum.
Thanks,
Karthick.

Sql Loader and carriage returns

I am currently trying to use sql loader to load data from flat files that was extracted from sybase using bcp and delimited with pipes. There are text and varchar columns that contain carriage return line feeds. I want to preserve these, but I can not load them into Oracle 8.05 using sql loader as it interprets them as end of record indicators. Does anyone have a way to solve this problem? Any assistance would be appreciated.
Thanks in advance,

How can i load the files?

SQL*Loader problem - not efficient, parsing error for big xml files

Hi Experts,
First of all, I would like to store xml files in object relation way. Therefore I created a schema and a table for it (see above).
I wants to propagate it (by using generated xml files), hence I created a control file for sql loader (see above).
I have two problems for it.
1, It takes a lot of time. It means I can upload a ~80MB file in 2 hours and a half.
2, At bigger files, I got the following error messages (OCI-31011: XML parsing failed OCI-19202: Error occurred in XML processing LPX-00243: element attribute value must be enclosed in quotes). It is quite interesting because my xml file is generated and I could generated and uploaded the first and second half of the file.
Can you help me to solve these problems?
Thanks,
Adam
