Question

我正在尝试使用Ecplise连接到SQLite数据库，但我有一些错误。这是我的Java代码和我输出的错误。请看看你是否可以帮助我。提前谢谢。


package jdb;
import java.sql.*;
public class Test {
  public static void main(String[] args) throws Exception {
    Class.forName("org.sqlite.JDBC");
    Connection conn = DriverManager.getConnection("jdbc:sqlite:/Applications/MAMP/db/sqlite/test.sqlite");
    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();


}
}

我在Ecplise中获得的内容：

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();

谢谢

Answer 1

确保Eclipse类路径中有sqlitejdbc-v056.jar

Answer 2

虽然也可以通过这种方式检索数据库，但它们是设置数据库的简单方法，如下载SQLlite数据库浏览器，那么您可以轻松升级数据。如果你要这样走，我会很快回复你。
