2、使用PreparedStatement对象
|
public void exec2(Connection conn){ try { Long beginTime = System.currentTimeMillis(); conn.setAutoCommit(false);//手动提交 PreparedStatement pst = conn.prepareStatement("insert into t1(id) values (?)"); for(int i=0;i<100000;i++){ pst.setInt(1, i); pst.execute(); } conn.commit(); Long endTime = System.currentTimeMillis(); System.out.println("pst:"+(endTime-beginTime)/1000+"秒");//计算时间 pst.close(); conn.close(); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } } |
