Body
On a linux desktop, when I tried, <pre><code>connection = DriverManager.getConnection("jdbc:sqlite:/path/to/test.db;foreign keys=true;"); </code></pre> sqlite3 (3.7.13) thought that my database file was /path/to/test.db;foreign keys=true. This led to the strange, but I guess appropriate, error: table does not exist See <a href="https://stackoverflow.com/questions/9895030/how-to-solve-no-such-table-while-inserting-exception-in-sqlite-data-base">how to solve no such table while inserting exception in sqlite data base</a> I thought I had fixed both of these issues by stuffing the foreign key statement into a property like so: <pre><code>private final Properties connectionProperties = new Properties(); connectionProperties.setProperty("PRAGMA foreign_keys", "ON"); private final String connectionString = String.format("jdbc:sqlite:%s", absolute_path_to_sqlite_db); Connection connection = DriverManager.getConnection(connectionString, connectionProperties); </code></pre> But even tho the database name issue was resolved, SQLite was still allowing constraint violations. Some more noodling with Xerial's driver and this is what finally worked: <pre><code>private final Properties connectionProperties = new Properties(); SQLiteConfig config = new SQLiteConfig(); config.enforceForeignKeys(true); connectionProperties = config.toProperties(); private final String connectionString = String.format("jdbc:sqlite:%s", absolute_path_to_sqlite_db); Connection connection = DriverManager.getConnection(connectionString, connectionProperties); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
