本文介绍如何使用 SQLite 的 JDBC 驱动来连接并操作 SQLite 数据库。包括下载 JDBC 驱动、配置 classpath 和示例代码等内容。

今天折腾了好久sqlite，刚刚搞定。以下是参照内容。

链接步骤：

Usage：

Download sqlite-jdbc-(VERSION).jar from http://www.xerial.org/maven/repository/artifact/org/xerial/sqlite-jdbc/, then append this jar file into your classpath.
load the JDBC driver org.sqlite.JDBC from your code. (see the example below)

Usage Example (Assuming sqlite-jdbc-(VERSION).jar is placed in the current directory)

> javac Sample.java
> java -classpath ".;sqlite-jdbc-(VERSION).jar"Sample   # in Windows
or 
> java -classpath ".:sqlite-jdbc-(VERSION).jar"Sample   # in Mac or Linux
name = leo
id =1
name = yui
id =2

Sample.java

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


publicclassSample
{
  publicstaticvoid main(String[] args)throwsClassNotFoundException
  {
    // load the sqlite-JDBC driver using the current class loader
    Class.forName("org.sqlite.JDBC");
    
    Connection connection =null;
    try
    {
      // create a database connection
      connection =DriverManager.getConnection("jdbc:sqlite:sample.db");
      Statement statement = connection.createStatement();
      statement.setQueryTimeout(30);  // set timeout to 30 sec.
      
      statement.executeUpdate("drop table if exists person");
      statement.executeUpdate("create table person (id integer, name string)");
      statement.executeUpdate("insert into person values(1, 'leo')");
      statement.executeUpdate("insert into person values(2, 'yui')");
      ResultSet rs = statement.executeQuery("select * from person");
      while(rs.next())
      {
        // read the result set
        System.out.println("name = "+ rs.getString("name"));
        System.out.println("id = "+ rs.getInt("id"));
      }
    }
    catch(SQLException e)
    {
      // if the error message is "out of memory", 
      // it probably means no database file is found
      System.err.println(e.getMessage());
    }
    finally
    {
      try
      {
        if(connection !=null)
          connection.close();
      }
      catch(SQLException e)
      {
        // connection close failed.
        System.err.println(e);
      }
    }
  }
}

The usage of SQLite-JDBC driver is the same with the original version. See http://www.zentus.com/sqlitejdbc/ for the general usage. For usage of JDBC, see my article about JDBC.

关键是要指定jdbc文件在classpath里，否则会找不到。
