推荐答案

首先阅读这些答案

查看 David Crawshaw 谁拥有 Java JDBC驱动程序对于SQLite。只需将他的 JAR文件添加到您的类路径并导入java.sql。*

check out website of David Crawshaw who has a Java JDBC driver for SQLite. Just add his JAR file to your classpath and import java.sql.*

他的测试应用程序将创建一个数据库文件，发送一些SQL命令来创建表，在表中存储一些数据，然后将其读回并显示在控制台上。它将在项目的根目录中创建test.db文件。

His test app will create a database file, send some SQL commands to create a table, store some data in the table, and read it back and display on console. It will create the test.db file in the root directory of the project.

public class Test {
    public static void main(String[] args) throws Exception {
        Class.forName("org.sqlite.JDBC");
        Connection conn = DriverManager.getConnection("jdbc:sqlite:test.db");
        Statement stat = conn.createStatement();
        stat.executeUpdate("drop table if exists people;");
        stat.executeUpdate("create table people (name, occupation);");
        PreparedStatement prep = conn.prepareStatement(
            "insert into people values (?, ?);");

        prep.setString(1, "Gandhi");
        prep.setString(2, "politics");
        prep.addBatch();
        prep.setString(1, "Turing");
        prep.setString(2, "computers");
        prep.addBatch();
        prep.setString(1, "Wittgenstein");
        prep.setString(2, "smartypants");
        prep.addBatch();

        conn.setAutoCommit(false);
        prep.executeBatch();
        conn.setAutoCommit(true);

        ResultSet rs = stat.executeQuery("select * from people;");
        while (rs.next()) {
            System.out.println("name = " + rs.getString("name"));
            System.out.println("job = " + rs.getString("occupation"));
        }
        rs.close();
        conn.close();
    }
  }
