Question

我正在尝试从MySQL数据库（保留）导出单个表（位置），但我不能通过使用java来实现。请帮帮我。

preparedStatement = connection.prepareStatement("mysqldump –uroot –proot keep location> db_test.sql");
        preparedStatement.execute();
        connection.close();

对于单个表，这里是代码。我们可以将此表保存到文件中。

    Class.forName("com.mysql.jdbc.Driver");
    String url = "jdbc:mysql://localhost:3306/abc";
    String username = "root";
    String password = "root";
    Connection connection = DriverManager.getConnection(url, username, password);

    Statement stmt = connection.createStatement();

    String filename = "d:/outfile.sql";
    String tablename = "abc";
    stmt.executeQuery("SELECT * INTO OUTFILE \"" + filename + "\" FROM " + tablename);

我无法使用java导出数据库。谁能帮我？
