Statement和PReparedStatement的區別就不多廢話了,直接說PreparedStatement最重要的addbatch()結構的使用.

1.建立鏈接（打電話撥號）   

   Connection   connection = getConnection();

2.不自動 Commit (瓜子不是一個一個吃，全部剝開放桌子上，然后一口舔了)

   connection.setAutoCommit(false);   

3.預編譯SQL語句,只編譯一回哦,效率高啊.(發明一個剝瓜子的方法,以后不要總想怎么剝瓜子好.就這樣剝.)
  PreparedStatement statement = connection.prepareStatement("INSERT INTO TABLEX VALUES(?, ?)");   

4.來一個剝一個,然后放桌子上

//記錄1
statement.setInt(1, 1);
statement.setString(2, "Cujo");
statement.addBatch();   

//記錄2
statement.setInt(1, 2);
statement.setString(2, "Fred");
statement.addBatch();   

//記錄3
statement.setInt(1, 3);
statement.setString(2, "Mark");
statement.addBatch();   

//批量執行上面3條語句. 一口吞了,很爽
int [] counts = statement.executeBatch();   

//Commit it 咽下去,到肚子(DB)里面
connection.commit();

stmt.addBatch("update  TABLE1 set 題目="盛夏話足部保健1"   where id="3407"");
stmt.addBatch("update  TABLE1 set 題目="夏季預防中暑膳食1" where id="3408"");
stmt.addBatch("INSERT INTO  TABLE1  VALUES("11","12","13","","")");
stmt.addBatch("INSERT INTO  TABLE1  VALUES("12","12","13","","")");
stmt.addBatch("INSERT INTO  TABLE1  VALUES("13","12","13","","")");
stmt.addBatch("INSERT INTO  TABLE1  VALUES("14","12","13","","")");
stmt.addBatch("INSERT INTO  TABLE1  VALUES("15","12","13","","")");
stmt.addBatch("INSERT INTO  TABLE1  VALUES("16","12","13","","")");
stmt.addBatch("INSERT INTO  TABLE1  VALUES("17","12","13","","")");
stmt.addBatch("INSERT INTO  TABLE1  VALUES("18","12","13","","")");

int [] updateCounts=stmt.executeBatch();
cn.commit();

例如:

    public static void execteBatch(Connection conn)throws Exception{
        String sql1 = "delete from student where id =3 ";
        String sql2 = "delete from student where id =5 ";
        String sql3 = "delete from student where id =6 ";
        String sql4 = "delete from student where id =7 ";
        PreparedStatement pstmt = conn.prepareStatement(sql1);
        pstmt.addBatch();
        pstmt.addBatch(sql2);
        pstmt.addBatch(sql3);
        pstmt.addBatch(sql4);
        pstmt.executeBatch();
    };
