1.SQLiteJDBC

SQLite JDBC Driver 可以在这个网站下载https://bitbucket.org/xerial/sqlite-jdbc/overview，当前稳定版本sqlite-jdbc-3.7.2.jar

2. Java 代码

添加sqlite-jdbc-3.7.2.jar，与你添加其他jar包的方法一样。

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class SQLiteTest
{
public static void main(String[] args) throws ClassNotFoundException
{
// 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);
}
}
}
}
