SQLite中的初学者 [英] Beginner in SQLite
问题描述
我以前没有使用过SQLite，我在寻找是否可以使用它。
I haven't used SQLite before and I am looking if I could use it.
我很困惑。例如，似乎没有一个与SQLite相关联的jdbc驱动程序来自官方的SQLite。
我发现一些帖子/网站（一些出现旧链接）提供的jdbc驱动程序，但我不情愿这些驱动程序如何稳定或如果它们缺少功能。
I am puzzled a bit. For example there does not seem to be a jdbc driver associated with SQLite that comes from the official SQLite.
I have found some posts/sites (some appear old links) that offer the jdbc driver but I am reluctant on how stable these drivers are or if they are missing features.
此外，我不清楚SQLite的用法。
Additionally I am not clear on the usage of SQLite.
例如，我试过下面的代码：
For example I tried the following code:
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();
}
此代码在我的应用程序目录中创建一个数据库文件。 br>
所以我想jdbc.jar创建这个？
所以我不需要运行我下载的sqlite3.exe？我应该从哪里获得jdbc驱动程序？
This code creates a database file in my application directory.
So I guess the jdbc.jar creates this???
So I don't need to run the sqlite3.exe that I downloaded? Where should I get the jdbc driver from?
更新：
这是我的观点。在PKeidel（http://www.zentus.com/sqlitejdbc/）的答案之一提供的链接是指从2009年起
推荐答案
您可以从这里下载JDBC驱动程序： http://www.zentus.com/sqlitejdbc/
You can download the JDBC Driver from here: http://www.zentus.com/sqlitejdbc/
只有在Windows上使用命令行时才需要sqlite3.exe pc。
The sqlite3.exe is only needed when you work with your command line on your windows pc. You don't need it when you want to access a database with Java.
从Java你必须：
- 下载JDBC驱动程序
- 将它添加到你的项目/ classpath
- 调用 Class.forName（org.sqlite.JDBC）;
- 现在你可以使用它例如您的第一篇文章
From Java you have to:
- download the JDBC Driver
- add it to your project/classpath
- call Class.forName("org.sqlite.JDBC");
- now you can use it like in your first post
