Hi Saisirisha,
Try this.
1> Take a Value Node(Employee) cardinality 0..n.
Employee Structure
Employee
|------Surname(Attribute)
|------FirstName(Attribute)
|------Category(Attribute)
2> Bind this value node(Employee) in the View datasource of table.
3> Try the code inside wdDoInit method.
try {
     // Load the JDBC-ODBC bridge
     Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
     // specify the ODBC data source's URL
     String url = "jdbc:odbc:SSPer";
     // connect
     Connection con = DriverManager.getConnection(url,"North","Ken");
     // create and execute a SELECT
     Statement stmt = con.createStatement();
     ResultSet rs = stmt.executeQuery
     ("SELECT Surname,FirstName,Category FROM Per");
     while (rs.next()) {
     // get current row values
     String Surname = rs.getString(1);
     String FirstName = rs.getString(2);
     int Category = rs.getInt(3);
     //create table row and add the value in the table
     IPrivate<Put View Name>.IEmployeeElement empElm = wdContext.createEmployeeElement();
        empElm.setSurname(Surname);
     empElm.setFirstName(FirstName);
     empElm.setCategory(Category);
     wdContext.nodeEmployee().addElement(empElm);
     // close statement and connection
     stmt.close();
     con.close();
} catch (java.lang.Exception ex) {
     wdComponentAPI.getMessageManager().reportException("Exception : "ex.getMessage()+,true);
