Hi,
The code below might answer few of your questions.
There is a restrcition on size of image, it must be less than 4KB.
//Code to insert image in database
//mytable is the table name that contains two fields in databse:name,image of type varchar and blob
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con =null ;
Statement stmt =null ;
con =DriverManager.getConnection  ("jdbc:oracle:thin:@<hostname>:1521:orclsid", "system","manager");
PreparedStatement preparedStatement = con.prepareStatement("insert into mytable (name,image) values (?,?)");
preparedStatement.setString(1,"Amol");
InputStream inputStream = new BufferedInputStream(new FileInputStream("C:\\WINNT\\Temp\\netscape\\images\\menubg.jpg"));
preparedStatement.setBinaryStream(2, inputStream, inputStream.available());
preparedStatement.executeUpdate();
preparedStatement.close();
inputStream.close(); To retrieve image,here is the snippet
ResultSet resultSet = stmt.executeQuery("select image from mytable'");
if (resultSet.next())
byte[] image1 = resultSet.getBytes("image");
FileOutputStream fos=new FileOutputStream("c://splash11.jpg"); //will retrieve bytes and create a file
//by the name specified
fos.write(image1);
