从SQLSERVER binary 导入到ORCALE Blob字段

      
     //照片处理段
     InputStream photo = rs.getBinaryStream("ZA9998");

     //照片处理       
            if(photo!=null){
            BLOB blob = null;
            Ex1Con.setAutoCommit(false);

            PreparedStatement pstmt = Ex1Con.prepareStatement
           ("update t_gs_person set PERSON_PHOTO=empty_blob() where PERSON_ID=?"); 
            pstmt.setInt(1,perrow+1);
            pstmt.executeUpdate();
            pstmt.close();

            pstmt = Ex1Con.prepareStatement

建议Statement对象名字区分开来,后来发现关闭对象时候，有状态对象未关闭。
