Java入门学习addBatch()用法

1.建立链接

Connection connection =getConnection();

2.不自动 Commit

connection.setAutoCommit(false);


3.预编译SQL语句,只编译一回哦,效率高啊

PreparedStatement statement = connection.prepareStatement("INSERT INTO TABLEX VALUES(?, ?)");
//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.
int [] counts = statement.executeBatch();
//Commit it  到(DB)里面
