Please recommend if we have options to read xml file and insert data into table without a temporary table.

DECLARE @data XML;
SET @data =N'<Root>
<List RecordID="946236" />
<List RecordID="946237" />
<List RecordID="946238" />
<List RecordID="946239" />
<List RecordID="946240" />
</Root>'
INSERT INTO t (id) SELECT T.customer.value('@RecordID', 'INT') AS id
FROM @data.nodes('Root/List')
AS T(customer);

Error in reading XML message and inserting data into another DB using DB link

Hi Experts,
I am getting error parsed XML message data while inserting into another DB table using DB link.
ORA-22804: remote operations not permitted on object tables or user-defined type columns.
Please help me.
Thanks.

ORA-22804: remote operations not permitted on object tables or user-defined type columns.
Looking at the error message assuming you might be doing the alter table statement on remote table unit_labels which is throwing the ORA-22804 error which is not permitted on remote tables.

How to read a CSV file and Insert data into an Oracle Table

@OP,
I have a Clob file as a in parameter in my PROC. . File is comma separated.need procedure that would parse this CLOB variable and populate in oracle table .You don't have a "clob file" as there's no such thing. CLOB is a datatype for storing large character based objects. A file is something on the operating system's filesystem.
So, why have you stored comma seperated data in a CLOB?
Where did this data come from? If it came from a file, why didn't you use SQL*Loader or, even better, External Tables to read and parse the data into structured format when populating the database with it?
If you really do have to parse a CLOB of data to pull out the comma seperated values, then you're going to have to write something yourself to do that, reading "lines" by looking for the newline character(s), and then breaking up the "lines" into the component data by looking for commas within it, using normal string functions such as INSTR and SUBSTR or, if necessary, REGEXP_INSTR and REGEXP_SUBSTR. If you have string data that contains commas but uses double quotes around the string, then you'll also have the added complexity of ignoring commas within such string data.
Like I say... it's much easier with SQL*Loader of External Tables as these are designed to parse such CSV type data.

Thanks you very much.

Hello,
You can use the TEXT_IO package.
Perform an over-all search (right upper corner) on TEXT_IO, and in the results you will find a manual on how to use the package.
Hope this will help you.

SQL server 2014 and VS 2013 - Dataflow task, read CSV file and insert data to SQL table

Hello everyone,
I was assigned a work item wherein, I've a dataflow task on For Each Loop container at control flow of SSIS package. This For Each Loop container reads the CSV files from the specified location one by one, and populates a variable with current
file name. Note, the tables where I would like to push the data from each CSV file are also having the same names as CSV file names.
On the dataflow task, I've Flat File component as a source, this component uses the above variable to read the data of a particular file. Now, here my question comes, how can I move the data to destination, SQL table, using the same variable name?
I've tried to setup the OLE DB destination component dynamically but it executes well only for first time. It does not change the mappings as per the columns of the second CSV file. There're around 50 CSV files, each has different set off columns
in it. These files needs to be migrated to SQL tables using the optimum way.
Does anybody know which is the best way to setup the Dataflow task for this requirement?
Also, I cannot use Bulk insert task here as we would like to keep a log of corrupted rows.
Any help would be much appreciated. It's very urgent.
Thanks, <b>Ankit Shah</b> <hr> Inkey Solutions, India. <hr> Microsoft Certified Business Management Solutions Professionals <hr> http://ankit.inkeysolutions.com

The standard Data Flow Task supports only static metadata defined during design time. I would recommend you check the commercial COZYROC
Data Flow Task Plus. It is an extension of the standard Data Flow Task and it supports dynamic metadata at runtime. You can process all your input CSV files using a single Data Flow Task
Plus. No programming skills are required.

Reading data in XML files and outputting information into xl spreadsheet

Can anyone provide me with coded examples or links to certain sites that can provide me with examples. I would be very grateful, thanks!!!

you will either have to use a third party toolkit or develop your own for this purpose. In case you develop your own, please be kind to share it with me ;)
I am not sure about the free ones. But Sitraka is know for developing such kits. For instance you may use sitraka's JClass which will be more then what you need. I guess JClass is free for evaluation, but you have to pay them after that.
all the best, and update this thread if you find anything for free !!

Read multiple files and save all into one output file(AGAIN)

Hi, guys
I need your help for reading data from multiple files and save the results into one output file. When files are selected from file chooser, my program read the data line by line , do some calculations and save the result into the output. I made an array to store input files and it seems to be working fine, but when it comes to SaveFile() function, issues NullPointException message.

Sorry about the long lines.
As you can see, all input files saved in array called files, however when OpenFile1() function is called, it take input (fileName_in) as a single file not an array. I'm assuming this causes the exception.
When there's muptiple inputs, program should take each file from getFileName() to outputToFile() sequentially.
Does anybody have an idea to solve this?
Thanks a lot!!

you naming convention is confussing. you should follows Java naming convention..you have a getXXX but decalred the return type as "void"...get usully means to return something...
your code is doing too much..and hard to follows..
1. get the selected files
for each selected file
process the file and return the result
write out the result.
/** close the precious resource */
public void closeResource(Reader in){
    if (in != null){
        try{ in.close(); }
        catch (Exception e){}
/** get the total number of line in a file */
public int getLineCount(File file) throws IOException{
    BufferedReader in = null;
    int lineCount = 0;
    try{
        in = new BufferedReader(new FileReader(file));
        while ((in.readLine() != null)
            lineCount++;
        return lineCount;
    finally{ closeResource (in); }
/** read the file */
public void processFile(File inFile, File outFile) throws IOException{
    BufferedReader in = null;
    StringBuffer result = new StringBuffer();
    try{
        in = new BufferedReader(new FileReader(inFile));
        String line = null;
        while ((in.readLine() != null){
            .. do something with the line
            result.append(....);
        writeToFile(outFile, result.toString());
    finally{ closeResource (in); }
public void writeToFile(File outFile, String result) throws IOException{
    PrintWriter out = null;
    try{
        out = new PrintWriter(new FileWriter(outFile, true)); // true for appending to the end of the file
        out.println(result);
    finally{ if (out != null){ try{ out.close(); } catch (Exception e){} } }

How to read the data from XML file and insert into oracle DB

Hi All,
I have below require ment.
I will receive data in the XML file. then i need to read that data and insert into oracle tables. please let me know how this can be handled.
Many Thanks.

Sounds a lot like this question, only with less details.

Using servlets to read from text file and insert data

Hi,
Can I use a servlet to read from a space delimited text file on the client computer and use that data to insert into a table in my database? I want to make it easy for my users to upload their data without having to have them use SQL*Loader. If so can someone give me a hint as how to get started? I appreciate it.
Thanks,
Colby

Create a page for the user to upload the file to your webserver and send a message (containing the file location) to a server app that will open the file, parse it, and insert it into your database. Make sure you secure the page.
or
Have the user paste the file into a simple web form that submits to a servlet that parses the data and inserts it into your db.

Reading XML file and skip certain elements/attributes??

Hi folks!
Suppose I have a XML file looking like this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE dvds SYSTEM "DTDtest.dtd">
<dvds>
<dvd>
<title>
Aliens
</title>
<director>
James Cameron
</director>
<format>
1.85:1
</format>
</dvd>
<dvd>
<title>
X-Men
</title>
<director>
Bryan Singer
</director>
<format>
2.35:1
</format>
</dvd>
</dvds>
In my Java application I want to read this XML file and print it on the screen (including all tags etc). So far, so good. BUT, if I want to skip certain elements, i.e. all information about the dvd 'X-Men', how am I supposed to do this? In other words, I would like my app to skip reading all information about X-Men and continue with the next <dvd>... </dvd> tag. Is this possible?
My code so far is from the XML tutorial from Sun and it looks like this:

A possibility that comes to mind is to create an XSLT script to do whatever it is you want - and call it from inside the program. The XSLT script can be stashed inside your .jar file by using getClass().getClassLoader().getResource("...")
- David

Please recommend if we have options to read xml file and insert data into table without a temporary table.
