Properties props = new Properties();
props.put("user", "intelligent");
props.put("password", "intercom");
props.put("SetBigStringTryClob", "true");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection("jdbc:odbc:intelligent",props);
try
{
PreparedStatement ps = con.prepareStatement("INSERT INTO persons1 values(?,?)");
String fn="D:\\test\\er.wma";
BufferedReader br = new BufferedReader(new FileReader(fn));
String nextLine = "";
StringBuffer sb = new StringBuffer();
while ((nextLine = br.readLine()) != null)
{ sb.append(nextLine); }
// Convert the content into to a string
String clobData = sb.toString(); // Return the data.
ps.setString(1,"krishna");
ps.setString(2,clobData);
ps.executeUpdate();
ps.close();
con.close();
