Chinook data set in hsqldb format

This project contains the Chinook data set as an embedded HSQLDB database.

It originated as the Chinook database version 1.4, which itself is an alternative to the Northwind database.

Schema

Chinook's schema consists of 11 tables:

TableRow count
Album347
Artist275
Customer59
Employee8
Genre25
Invoice412
InvoiceLine2,240
MediaType5
Playlist18
PlaylistTrack8,715
Track3,503

Its size is about 900 KB uncompressed, 160 KB compressed.

Here is a schema diagram:

Using the data set

The data set is packaged as a jar file that is published to Maven Central as a Maven artifact. To use the data in your Java application, add the artifact to your project's dependencies:

<dependency>
  <groupId>net.hydromatic</groupId>
  <artifactId>chinook-data-hsqldb</artifactId>
  <version>0.2</version>
</dependency>

Now you can connect using Java code:

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

final String url = "jdbc:hsqldb:res:chinook";
final String sql = "select \"EmployeeId\", \"LastName\" from \"Employee\"";
try (Connection c = DriverManager.getConnection(url, "sa", "");
    Statement s = c.createStatement();
    ResultSet r = s.executeQuery(sql)) {
  while (r.next()) {
    System.out.println(r.getInt(1) + ":" + r.getString(2));
  }
}

You can also connect using a JDBC interface such as sqlline. Make sure that chinook-data-hsqldb.jar is on the class path, and start sqlline:

$ ./sqlline
sqlline version 1.12.0
sqlline> !connect jdbc:hsqldb:res:chinook sa ""
0: jdbc:hsqldb:res:chinook> select count(*) from "chinook"."Track";
+----------------------+
|          C1          |
+----------------------+
| 3503                 |
+----------------------+
1 row selected (0.004 seconds)
0: jdbc:hsqldb:res:chinook> !quit

If you use username and password "CHINOOK" and "CHINOOK", the default schema is "chinook", so you can omit the table prefix, if you wish:

$ ./sqlline
sqlline version 1.12.0
sqlline> !connect jdbc:hsqldb:res:chinook CHINOOK CHINOOK
0: jdbc:hsqldb:res:chinook> select count(*) from "Track";
+----------------------+
|          C1          |
+----------------------+
| 3503                 |
+----------------------+
1 row selected (0.004 seconds)
0: jdbc:hsqldb:res:chinook> !quit
