How to read/write text file to db2 by using java code

Hai
I created the table to insert a clob data as follows
db2 => create table ctest(datas clob(65536))
DB20000I The SQL command completed successfully.
db2 => describe table ctest
Column Type Type
name schema name Length Scale Nulls
DATAS SYSIBM CLOB 65536 0 Yes
1 record(s) selected.
I tried the following java code to insert a clob data.
public static synchronized Connection getConnection() throws Exception {
Connection m_connectionDatabase = null;
try {
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
// Get the connection to the database.
m_connectionDatabase = DriverManager.getConnection(
"jdbc b2 ps","","");
}catch (Exception e) {
throw new Exception("Failed to connect to the database. ", e);
return m_connectionDatabase;
public static void main(String a[]) {
File file = new File("d:\\a.txt");
InputStream fis = new FileInputStream(file);
Connection con = getConnection();
PreparedStatement pstmt = con.prepareStatement("insert into ctest values(?)");
//try 1
pstmt.setAsciiStream(1,fis,(int)file.length());
// try 2
pstmt.setCharacterStream(1,fis,(int)(file.length()));
// try 3
pstmt.setBinaryStream(1,fis,(int)(file.length()));
// try 4
byte[] b = new byte[fis.available()];
fis.read(b);
pstmt.setBytes(1, b);
// try 5
byte[] b = new byte[fis.available()];
fis.read(b);
pstmt.setString(1, new String(b));
pstmt.executeUpdate();
pstmt.close();
fis.close();
Result:
If the file size is less than 32kb, it inserted successfully.
but if more than 32kb, it throws follwing exception
COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL0352N An unsupported SQLTYPE was encountered in position "1" of the input list (SQLDA). SQLSTATE=56084

Can any body please help out to insert clob value.
Thanks in advance

How to read\write text file into oracle database.

Hello,
I am having text file called getInfo in c:\temp folder. I would like to populate data from text file to data base. How to proceed. Could anybody help me out.
Thanks,
Shailu

Here is a web page with easy to follow instructions regarding external files: http://www.adp-gmbh.ch/ora/misc/ext_table.html.
Now I understand what all the excitement is over external tables.
"External tables can read flat files (that follow some rules) as though they were ordinary (although read-only) Oracle tables. Therefore, it is convenient to use external tables to load flat files into the DB." -from the above link.

Sorry, that doesn't make much sense.
The XML you gave is a configuration file for txt2xml utility. It doesn't represent the output format.
Are you a user of this utility?

How to read a text file through pl/sql

How to read a text file through pl/sql

pl/sql runs inside the database. so your file also should be on the database server file system for you to be able to read.
check out UTL_FILE package. This is the database package to read/write files on the database server.

How to read a text file using Java

Guys,
Good day!
Please help me how to read a text file using Java and create/convert that text file into XML.
Thanks and God Bless.
Regards,
I-Talk

     public void fileRead(){
             File aFile =new File("myFile.txt");
         BufferedReader input = null;
         try {
           input = new BufferedReader( new FileReader(aFile) );
           String line = null;
           while (( line = input.readLine()) != null){
         catch (FileNotFoundException ex) {
           ex.printStackTrace();
         catch (IOException ex){
           ex.printStackTrace();
     }This code is to read a text file. But there is no such thing that will convert your text file to xml file. You have to have a defined XML format. Then you can read your data from text files and insert them inside your xml text. Or you may like to read xml tags from text files and insert your own data. The file format of .txt and .xml is far too different.

How to get the values from struct data type using java code..?

Hi ,
I am newer to java.
we are using oracle database.
How to get the data from struct data type using java code.
Thanks in Advance.
Regards,
kumar

Hi Rajeev,
To retrieve a FilterContainer you will need to traverse the report structure:
ReportStructure boReportStructure = boDocumentInstance.getStructure();
ReportContainer boReportContainer = (ReportContainer) boReportStructure.getReportElement(0);
FilterContainer boFilterContainer = null;
if (boReportContainer.hasFilter()) {
boFilterContainer = boReportContainer.getFilter();
} else {
boFilterContainer = boReportContainer.createFilter(LogicalOperator.AND);
Calling boDocumentInstance.getStructure() will retrieve the entire structure for the document.
Calling boReportStructure.getReportElement(0) will retrieve the structure for the first report of the document.
Hope this helps.
Regards,
Dan

How to Read the "text file and csv file" through powershell Scripts

Hi All
i need to add a multiple users in a particular Group through powershell Script how to read the text and CSV files in powershell
am completly new to Powershell scripts any one pls respond ASAP.with step by step process pls
Regards:
Rajeshreddy.k

Hi Rajeshreddy.k,
To add multiple users to one group, I wouldn't use a .csv file since the only value you need from a list is the users to be added.
To start create a list of users that should be added to the group, import this list in a variable called $users, the group distinguishedName in a variable called $Group and simply call the ActiveDirectory cmdlet Add-GroupMember.
$Users = Get-Content -Path 'C:\ListOfUsernames.txt'
$Group = 'CN=MyGroup,OU=MyOrg,DC=domain,DC=lcl'
Add-ADGroupMember -Identity $Group -Members $Users
