轉---addBatch()用法

PreparedStatement.addbatch()的使用
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.建立連結   
  Connection connection =getConnection();

2.不自動 Commit
connection.setAutoCommit(false);  

3.先行編譯SQL語句,只編譯一回哦,效率高啊
PreparedStatement statement = connection.prepareStatement("INSERT INTO TABLEX VALUES(?, ?)");  

//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.
int [] counts = statement.executeBatch();  

//Commit it  到(DB)裡面
