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 --dbname=<DB_DATABASE_NAME> --username=<DB_USERNAME> to connect to the database via the container directly.

(Replace <DB_DATABASE_NAME> and <DB_USERNAME> with the values from your .env file). :::

Assets

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

SELECT * FROM "assets" WHERE "originalFileName" LIKE '%_2023_%'; -- all files with _2023_ in the middle

SELECT * FROM "assets" WHERE "originalPath" = 'upload/library/admin/2023/2023-09-03/PXL_2023.jpg';
