+# Demo Notes
+When you run Trilium for the first time, it will generate a new database containing demo notes. These notes showcase its many features, such as:

+*   <a class="reference-link" href="../../Note%20Types/Relation%20Map.md">Relation Map</a>
+*   <a class="reference-link" href="../Advanced%20Showcases/Day%20Notes.md">Day Notes</a>

+
+### Restoring Demo Notes
+
+There are some cases in which you may want to restore the original demo notes. For example, if you experimented with some of the more advanced features and want to see the original reference, or if you simply want to explore the latest version of the demo notes, which might showcase new features.
+
+You can easily restore the demo notes by using Trilium's built-in import feature by importing them:
+
+*   Download [this .zip archive](https://github.com/TriliumNext/Notes/raw/develop/db/demo.zip) with the latest version of the demo notes
+*   Right click on any note in your tree under which you would like the demo notes to be imported
+*   Click "Import into note"
+*   Select the .zip archive to import it

+# Manually altering the database
+There are some situations where modifying the SQLite database that Trilium uses is desirable.
+
+If you are doing any advanced development or troubleshooting where you manually modify the database, you might want to consider creating backups of your `document.db` file.
+
+## Modifying it internally using the SQL Console
+
+The SQL Console is Trilium's built-in database editor.
+
+See <a class="reference-link" href="Manually%20altering%20the%20database/SQL%20Console.md">SQL Console</a>.
+
+## Externally modifying the database
+
+Sometimes the SQL Console cannot be used (for example if the application cannot start).
+
+When making external modifications, consider closing the desktop application. If modifying the server database, then stop the service or Docker container.
+
+### Using DB Browser for SQLite
+
+DB Browser for SQLite is a cross-platform editor that can be used to alter the database using a graphical user interface.
+
+To do so:
+
+1.  In the main menu, select File → Open database… and navigate to the database in the [Data directory](../../Installation%20%26%20Setup/Data%20directory.md).
+2.  Select the _Execute SQL_ tab.
+3.  Type in the desired SQL statement.
+4.  Press the "Play" button in the toolbar underneath the "Execute SQL" tab (or F5 key).
+5.  Press "Write Changes" in the main toolbar.
+6.  Close the application or close the database.
+

+
+### Using the SQLite CLI
+
+First, start the SQLite 3 CLI by specifying the path to the database:
+
+```
+sqlite3 ~/.local/share/trilium-data/document.db
+```
+
+*   In the prompt simply type the statement and make sure it ends with a `;` character.
+*   To exit, simply type `.quit` and enter.

+# SQL Console
+The SQL Console is Trilium's built-in database editor.
+
+It can be accessed by going to the [global menu](../../../Basic%20Concepts%20and%20Features/UI%20Elements) → Advanced → Open SQL Console.
+
+![](SQL%20Console_image.png)
+
+### Interaction
+
+*   Hovering the mouse over one of the tables listed at the top of the document will show the columns and their data type.
+*   Only one SQL statement can be run at once.
+*   To run the statement, press the ![](3_SQL%20Console_image.png)icon.
+*   For queries that return a result, the data will displayed in a table.
+    
+    ![](1_SQL%20Console_image.png)
+
+### Saved SQL console
+
+SQL queries or commands can be saved into a dedicated note.
+
+To do so, simply write the query and press the ![](2_SQL%20Console_image.png)button. Once saved, the note will appear in [Day Notes](../../Advanced%20Showcases/Day%20Notes.md).
+
+*   The SQL expression will not be displayed by default, but it can still be viewed by going to the note context menu and selecting _Note source_.
+*   The expression cannot be modified. If needed, recreate it by copying the statement back into the SQL console and then saving it again.
