		System.out.println(sql);
		try {
			Statement stmt = this.getConnecttion().createStatement();
			int stat = stmt.executeUpdate(sql);
			System.out.println("insert Complete .." + stat);
			stmt.close();
		} catch (SQLException e) {
			System.out.println("Not insert Complete ..");
			e.printStackTrace();
		} finally {
