Oracle addBatch()用法实例详解
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
