# Database Queries

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)).

## Assets

|
|
|
:::note
|
|
The `"originalFileName"` column is the name of the file at time of upload, including the extension.
|
|
:::
|
|
|
|
```sql title="Find by original filename"
|
|
SELECT * FROM "assets" WHERE "originalFileName" = 'PXL_20230903_232542848.jpg';
|
|
SELECT * FROM "assets" WHERE "originalFileName" LIKE 'PXL_%'; -- all files starting with PXL_
|
|
SELECT * FROM "assets" WHERE "originalFileName" LIKE '%_2023_%'; -- all files with _2023_ in the middle
|
|
```
|
|
|
|
```sql title="Find by path"
|
|
SELECT * FROM "assets" WHERE "originalPath" = 'upload/library/admin/2023/2023-09-03/PXL_20230903_232542848.jpg';
|
|
SELECT * FROM "assets" WHERE "originalPath" LIKE 'upload/library/admin/2023/%';
|
|
```
|
|
|

:::note
|
|
You can calculate the checksum for a particular file by using the command `sha1sum <filename>`.

```sql title="Find by checksum (SHA-1)"
