Java and SQLite [closed]

Question

I'm attracted to the neatness that a single file database provides. What driver/connector library is out there to connect and use SQLite with Java.

I've discovered a wrapper library, http://www.ch-werner.de/javasqlite, but are there other more prominent projects available?

Answer 1

I found your question while searching for information with SQLite and Java. Just thought I'd add my answer which I also posted on my blog.

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

I found a Java JDBC driver for SQLite. Just add the 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. You can run this example with java -cp .:sqlitejdbc-v056.jar Test.

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 {
        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();
    }
  }

The wiki lists some more wrappers:

• Java wrapper (around a SWIG interface): http://tk-software.home.comcast.net/
• A good tutorial to use JDBC driver for SQLite. (it works at least !) http://www.ci.uchicago.edu/wiki/bin/view/VDS/VDSDevelopment/UsingSQLite
• Cross-platform JDBC driver which uses embedded native SQLite libraries on Windows, Linux, OS X, and falls back to pure Java implementation on other OSes: https://github.com/xerial/sqlite-jdbc (formerly zentus)
• Another Java - SWIG wrapper. It only works on Win32. http://rodolfo_3.tripod.com/index.html
• sqlite-java-shell: 100% pure Java port of the sqlite3 commandline shell built with NestedVM. (This is not a JDBC driver).
• SQLite JDBC Driver for Mysaifu JVM: SQLite JDBC Driver for Mysaifu JVM and SQLite JNI Library for Windows (x86) and Linux (i386/PowerPC).

I understand you asked specifically about SQLite, but maybe HSQL database would be a better fit with Java. It is written in Java itself, runs in the JVM, supports in-memory tables etc. and all that features make it quite usable for prototyping and unit-testing.
