关于PreparedStatement.addBatch()方法 Statement和PreparedStatement的区别就不多废话了,直接说PreparedStatement最重要的addbatch()结构的使用. 1.建立链接,(打电话拨号 )        Connection    connection =getConnection(); 2.不自动 Commit (瓜子不是一个一个吃,全部剥开放桌子上,然后一口舔了) con Statement和PreparedStatement的区别就不多废话了,直接说PreparedStatement最重要的addbatch()结构的使用.1.建立链接,(打电话拨号 )Connection    connection =getConnection();2.不自动 Commit (瓜子不是一个一个吃,全部剥开放桌子上,然后一口舔了)connection.setAutoCommit(false);3.预编译SQL语句,只编译一回哦,效率高啊.(发明一个剥瓜子的方法,以后不要总想怎么剥瓜子好.就这样剥.) PreparedStatement statement = connection.prepareStatement("INSERT INTO TABLEX VALUES(?, ?)");4.来一个剥一个,然后放桌子上//记录1 statement.setInt(1, 1); statement.setString(2, "Cujo"); statement.addBatch();//记录2 statement.setInt(1, 2); statement.setString(2, "Fred"); statement.addBatch();//记录3 statement.setInt(1, 3); statement.setString(2, "Mark"); statement.addBatch();//批量执行上面3条语句. 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 题目="盛夏话足部保健1"   where id="3407""); stmt.addBatch("update  TABLE1 set 题目="夏季预防中暑膳食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(); };
