Java JDBC - 如何使用開放辦公室數(shù)據(jù)庫(hsqldb)創(chuàng)建JDBC連接

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class Main {
  public static void main(String[] args) throws Exception {
    String db_file_name_prefix = "c:\\mydbdir\\mydb";

    Connection con = null;
    Class.forName("org.hsqldb.jdbcDriver");

    con = DriverManager.getConnection(
        "jdbc:hsqldb:file:" + db_file_name_prefix, // filenames
        "sa", // username
        ""); // password

    Statement statement = con.createStatement();
    ResultSet rs = statement.executeQuery("SELECT * FROM \"User\"");
    while (rs.next()) {
      System.out.print("ID: " + rs.getString("ID"));
      System.out.print(" first name: " + rs.getString("firstname"));
      System.out.println(" last name: " + rs.getString("lastname"));
    }
    statement.close();
    con.close();
  }
}
