# Database Queries

:::danger
Keep in mind that mucking around in the database might set the moon on fire. Avoid modifying the database directly when possible, and always have current backups.
:::

:::tip
Run `docker exec -it immich_postgres psql immich <DB_USERNAME>` to connect to the database via the container directly.

(Replace `<DB_USERNAME>` with the value from your [`.env` file](/docs/install/environment-variables#database)).

The `"originalFileName"` column is the name of the file at time of upload, including the extension.
