SQLite JDBC Driver

SQLite JDBC, developed by Taro L. Saito, is a library for accessing and creating SQLite database files in Java.

Our SQLiteJDBC library requires no configuration since native libraries for major OSs, including Windows, Mac OS X, Linux etc., are assembled into a single JAR (Java Archive) file. The usage is quite simple; download our sqlite-jdbc library, then append the library (JAR file) to your class path.

See the sample code.

What is different from Zentus's SQLite JDBC?

The current sqlite-jdbc implementation is based on the code of Zentus's SQLite JDBC driver (missing link). We have improved it in two ways:

  • Support major operating systems by embedding native libraries of SQLite, compiled for each of them.
  • Remove manual configurations

In the original version, in order to use the native version of sqlite-jdbc, users had to set a path to the native codes (dll, jnilib, so files, etc.) through the command-line arguments, e.g., -Djava.library.path=(path to the dll, jnilib, etc.), or -Dorg.sqlite.lib.path, etc. This process was error-prone and bothersome to tell every user to set these variables. Our SQLiteJDBC library completely does away these inconveniences.

Another difference is that we are keeping this SQLiteJDBC library up-to-date to the newest version of SQLite engine, because we are one of the hottest users of this library. For example, SQLite JDBC is a core component of UTGB (University of Tokyo Genome Browser) Toolkit, which is our utility to create personalized genome browsers.

Usage

SQLite JDBC is a library for accessing SQLite databases through the JDBC API. For the general usage of JDBC, see JDBC Tutorial or Oracle JDBC Documentation.

  1. Download sqlite-jdbc-(VERSION).jar from the download page (or by using Maven) then append this jar file into your classpath.
  2. Load the JDBC driver org.sqlite.JDBC from your code. (see the example below)

More usage examples are available at https://bitbucket.org/xerial/sqlite-jdbc/wiki/Usage

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;

public class Sample
{
  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);
      }
    }
  }
}

How to Specify Database Files

Here is an example to select a file C:\work\mydatabase.db (in Windows)

Connection connection = DriverManager.getConnection("jdbc:sqlite:C:/work/mydatabase.db");

A UNIX (Linux, Mac OS X, etc) file /home/leo/work/mydatabase.db

Connection connection = DriverManager.getConnection("jdbc:sqlite:/home/leo/work/mydatabase.db");

How to Use Memory Databases

SQLite supports on-memory database management, which does not create any database files. To use a memory database in your Java code, get the database connection as follows:

Connection connection = DriverManager.getConnection("jdbc:sqlite::memory:");

Beta Release

The early releases (beta) of sqlite-jdbc with some advanced features are available from here

  • The old releases are still available from here, but the site might be closed in future.

Supported Operating Systems

Since sqlite-jdbc-3.6.19, the natively compiled SQLite engines will be used for the following operating systems:

  • Windows XP, Vista (Windows, x86 architecture, x86_64)
  • Mac OS X 10.4 (Tiger), 10.5(Leopard), 10.6 SnowLeopard (for i386, x86_64, Intel CPU machines)
  • Linux i386 (Intel), amd64 (64-bit X86 Intel processor)

In the other OSs not listed above, the pure-java SQLite is used. (Applies to versions before 3.7.15)

If you want to use the native library for your OS, [build the source from scratch.

How does SQLiteJDBC work?

Our SQLite JDBC driver package (i.e., sqlite-jdbc-(VERSION).jar) contains three types of native SQLite libraries (sqlite-jdbc.dll, sqlite-jdbc.jnilib, sqlite-jdbc.so), each of them is compiled for Windows, Mac OS and Linux. An appropriate native library file is automatically extracted into your OS's temporary folder, when your program loads org.sqlite.JDBC driver.

Using SQLiteJDBC with Maven2

If you are familiar with Maven2, add the following XML fragments into your pom.xml file. With those settings, your Maven will automatically download our SQLiteJDBC library into your local Maven repository, since our sqlite-jdbc libraries are synchronized with the Maven's central repository.

<dependencies>
    <dependency>
      <groupId>org.xerial</groupId>
      <artifactId>sqlite-jdbc</artifactId>
      <version>3.7.2</version>
    </dependency>
</dependencies>

Using SQLiteJDBC with Tomcat6 Web Server

Do not include sqlite-jdbc-(version).jar in WEB-INF/lib folder of your web application package, since multiple web applications hosted by the same Tomcat server cannot load the sqlite-jdbc native library more than once. That is the specification of JNI (Java Native Interface). You will observe UnsatisfiedLinkError exception with the message "no SQLite library found".

Work-around of this problem is to put sqlite-jdbc-(version).jar file into (TOMCAT_HOME)/lib direcotry, in which multiple web applications can share the same native library file (.dll, .jnilib, .so) extracted from this sqlite-jdbc jar file.

If you are using Maven for your web application, set the dependency scope as 'provided', and manually put the SQLite JDBC jar file into (TOMCAT_HOME)/lib folder.

<dependency>
    <groupId>org.xerial</groupId>
    <artifactId>sqlite-jdbc</artifactId>
    <version>3.7.2</version>
    <scope>provided</scope>
</dependency>
