PreparedStatement.addbatch()的使用

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

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
