SQLite JDBC is a library for accessing and creating https://www.sqlite.org[SQLite] database files in Java.

Our SQLiteJDBC library requires no configuration since native libraries for major OSs, including Windows, macOS, Linux etc., are assembled into a single JAR (Java Archive) file.

== Project Status

The project is maintained, but is not being actively developed:

• We follow every new version of SQLite and will release a corresponding version of our driver.
• Bugs will be investigated, and fixed if possible.
• New features are driven by pull requests.

The current maintainer of the project is https://github.com/gotson[gotson].

== Usage

➡️ More usage examples and configuration are available in link:USAGE.md[USAGE.md]

SQLite JDBC is a library for accessing SQLite databases through the JDBC API. For the general usage of JDBC, see https://docs.oracle.com/javase/tutorial/jdbc/index.html[JDBC Tutorial] or https://www.oracle.com/technetwork/java/javase/tech/index-jsp-136101.html[Oracle JDBC Documentation].

. <<Download,Download>> sqlite-jdbc-{project-version}.jar then append this jar file into your classpath. . Open a SQLite database connection from your code. (see the example below)

=== Example usage

Assuming sqlite-jdbc-{project-version}.jar is placed in the current directory.

[source,shell,subs="attributes+"]

javac Sample.java java -classpath ".;sqlite-jdbc-{project-version}.jar" Sample # in Windows or java -classpath ".:sqlite-jdbc-{project-version}.jar" Sample # in macOS or Linux name = leo id = 1 name = yui id = 2

=== Sample.java

[source,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)
  {
    // NOTE: Connection and Statement are AutoCloseable.
    //       Don't forget to close them both in order to avoid leaks.
    try
    (
      // create a database connection
      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
      e.printStackTrace(System.err);
    }
  }
}

== How does SQLiteJDBC work?

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

=== Supported Operating Systems

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

|=== | |x86 |x86_64 |armv5 |armv6 |armv7 |arm64 |ppc64 | riscv64

|Windows |✔ |✔ | | |✔ |✔ | | |macOS | |✔ | | | |✔ | | |Linux (libc) |✔ |✔ |✔ |✔ |✔ |✔ |✔ |✔ |Linux (musl) |✔ |✔ | | | |✔ | | |Android (API Level 24+) |✔ |✔ |✔ | | |✔ | | |FreeBSD |✔ |✔ | | | |✔ | | |===

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, link:./CONTRIBUTING.md[build the source from scratch].

=== GraalVM native-image support

Sqlite JDBC supports https://www.graalvm.org/native-image/[GraalVM native-image] out of the box starting from version 3.40.1.0. There has been rudimentary support for some versions before that, but this was not actively tested by the CI.

By default, the sqlitejdbc library for the compilation target will be included in the native image, accompanied by the required JNI configuration. At runtime, this library will be extracted to the temp folder and loaded from there. For faster startup however, it is recommended to set the org.sqlite.lib.exportPath property at build-time. This will export the sqlitejdbc library at build-time to the specified directory, and the library will not be included as a resource. As a result, the native image itself will be slightly smaller and the overhead of exporting the library at run-time is eliminated, but you need to make sure the library can be found at run-time. The best way to do this is to simply place the library next to the executable.

==== CLI example

[source,shell]

native-image -Dorg.sqlite.lib.exportPath=/outDir -H:Path=/outDir -cp foo.jar org.example.Main

This will place both the sqlitejdbc shared library and the native-image output in the ~/outDir folder.

=== Maven example

This example uses the https://graalvm.github.io/native-build-tools/latest/index.html[native-build-tools] maven plugin:

[source,xml]

This will automatically place the sqlitejdbc library in the /target folder of your project, creating a functional execution environment. When packaging the resulting app, simply include the library in the distribution bundle.

== Download

Download from https://search.maven.org/artifact/org.xerial/sqlite-jdbc[Maven Central] or from the https://github.com/xerial/sqlite-jdbc/releases[releases] page.

[source,xml,subs="attributes+"]

Snapshots of the development version are available in https://oss.sonatype.org/content/repositories/snapshots/org/xerial/sqlite-jdbc/[Sonatype's snapshots repository].

=== Validating downloads

Maven Central resources are signed using https://gnupg.org/[GPG] and the signature files, ending in .asc, are available in the same location as the other downloads.

The following key is currently used to sign releases:

=== Project versioning explained

The project's version follows the version of the SQLite library that is bundled in the jar, with an extra digit to denote the project's increment.

For example, if the SQLite version is 3.39.2, the project version will be 3.39.2.x, where x starts at 0, and increments with every release that is not changing the SQLite version.

If the SQLite version is updated to 3.40.0, the project version will be updated to 3.40.0.0.

=== Hint for maven-shade-plugin

You may need to add shade plugin transformer to solve No suitable driver found for jdbc:sqlite: issue.
