How to use SQLite with Java

I have been coding in Java for a while now. I have also known about SQLite but never used it… Well I have have used it through other applications but never in an app that I coded. So I needed it for a project this week and its so simple use!

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

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.

package com.rungeek.sqlite;

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

public class Test {
    public static void main(String[] args) throws Exception {
        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.setString(1, "Turing");
        prep.setString(2, "computers");
        prep.setString(1, "Wittgenstein");
        prep.setString(2, "smartypants");


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