Here's the code:
myPreparedStatement = myConnection.prepareStatement ("INSERT INTO AMC_NEWB_XML VALUES (?, ?, ?, ?)"); myPreparedStatement.setString(1, mySessionId); myPreparedStatement.setInt(2, 1); Calendar myCal = Calendar.getInstance(); java.util.Date myUtilDate = myCal.getTime(); java.sql.Date mySqlDate = new java.sql.Date(myUtilDate.getTime()); myPreparedStatement.setDate(3, mySqlDate); OracleConnection myOracleConnection = (OracleConnection)myConnection; myPreparedStatement.setClob(4, oracle.sql.CLOB.empty_lob()); int myRowCount = myPreparedStatement.executeUpdate(); myConnection.commit(); System.out.println("Successful update of "+myRowCount+" row"); //myReader.close(); myPreparedStatement.close(); //Now select the clob from the row just created. String mySql = "select XML_DATA from AMC_NEWB_XML where SESSION_ID = ? FOR UPDATE"; CallableStatement myCallableStatement = myConnection.prepareCall(mySql); myCallableStatement.setString(1, mySessionId); boolean myRes = myCallableStatement.execute(); System.out.println("Retrieved the CLOB from the DB");
Use preparedStatment as you did when you registered the empty CLOB.
ResultSet rs = myPreparedStatement.execute(); rs.next(); CLOB myClob = ((OracleResultSet) rs).getCLOB("XML_DATA"); // go to work on you CLOB
