資料庫查詢

危险

請注意，直接修改資料庫可能會引發不可預測的問題。盡量避免直接改動資料庫，並且務必備份最新資料。

提示

執行 docker exec -it immich_postgres psql --dbname=<DB_DATABASE_NAME> --username=<DB_USERNAME> 以直接透過容器連接資料庫。

（將 <DB_DATABASE_NAME> 和 <DB_USERNAME> 替換為您的 .env 檔案 中的值）。

資產

名稱

注释

欄位 "originalFileName" 是文件上傳時的名稱，包括副檔名。

透過原始檔名查詢

SELECT * FROM "asset" WHERE "originalFileName" = 'PXL_20230903_232542848.jpg';
SELECT * FROM "asset" WHERE "originalFileName" LIKE 'PXL_%'; -- 所有檔名以 PXL_ 開頭的文件
SELECT * FROM "asset" WHERE "originalFileName" LIKE '%_2023_%'; -- 所有檔名中間有 _2023_ 的文件

透過路徑查詢

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

ID

透過 ID 查詢

SELECT * FROM "asset" WHERE "id" = '9f94e60f-65b6-47b7-ae44-a4df7b57f0e9';

透過部分 ID 查詢

SELECT * FROM "asset" WHERE "id"::text LIKE '%ab431d3a%';

校驗碼

注释

您可以使用命令 sha1sum <filename> 計算特定文件的校驗碼。

透過校驗碼 (SHA-1) 查詢

SELECT encode("checksum", 'hex') FROM "asset";
SELECT * FROM "asset" WHERE "checksum" = decode('69de19c87658c4c15d9cacb9967b8e033bf74dd1', 'hex');
SELECT * FROM "asset" WHERE "checksum" = '\x69de19c87658c4c15d9cacb9967b8e033bf74dd1'; -- 替代表示法

查詢具有相同校驗碼 (SHA-1) 的重複資產 (排除已刪除檔案)

SELECT T1."checksum", array_agg(T2."id") ids FROM "asset" T1
  INNER JOIN "asset" T2 ON T1."checksum" = T2."checksum" AND T1."id" != T2."id" AND T2."deletedAt" IS NULL
  WHERE T1."deletedAt" IS NULL GROUP BY T1."checksum";

元資料

動態照片

SELECT * FROM "asset" WHERE "livePhotoVideoId" IS NOT NULL;

透過描述查詢

SELECT "asset".*, "asset_exif"."description" FROM "asset_exif"
  JOIN "asset" ON "asset"."id" = "asset_exif"."assetId"
  WHERE TRIM("asset_exif"."description") <> ''; -- 所有帶有描述的文件
SELECT "asset".*, "asset_exif"."description" FROM "asset_exif"
  JOIN "asset" ON "asset"."id" = "asset_exif"."assetId"
  WHERE "asset_exif"."description" ILIKE '%string to match%'; -- 透過字串查詢

無元資料

SELECT "asset".* FROM "asset_exif"
  LEFT JOIN "asset" ON "asset"."id" = "asset_exif"."assetId"
  WHERE "asset_exif"."assetId" IS NULL;

檔案大小 < 100,000 bytes，按大小排序

SELECT * FROM "asset"
  JOIN "asset_exif" ON "asset"."id" = "asset_exif"."assetId"
  WHERE "asset_exif"."fileSizeInByte" < 100000
  ORDER BY "asset_exif"."fileSizeInByte" ASC;

類型

透過類型查詢

SELECT * FROM "asset" WHERE "asset"."type" = 'VIDEO';
SELECT * FROM "asset" WHERE "asset"."type" = 'IMAGE';

透過類型統計數量

SELECT "asset"."type", COUNT(*) FROM "asset" GROUP BY "asset"."type";

透過類型統計數量 (分使用者)

SELECT "user"."email", "asset"."type", COUNT(*) FROM "asset"
  JOIN "user" ON "asset"."ownerId" = "user"."id"
  GROUP BY "asset"."type", "user"."email" ORDER BY "user"."email";

標籤

依標籤統計數量

SELECT "t"."value" AS "tag_name", COUNT(*) AS "number_assets" FROM "tag" "t"
  JOIN "tag_asset" "ta" ON "t"."id" = "ta"."tagsId" JOIN "asset" "a" ON "ta"."assetsId" = "a"."id"
  WHERE "a"."visibility" != 'hidden'
  GROUP BY "t"."value" ORDER BY "number_assets" DESC;

依標籤統計數量 (分使用者)

SELECT "t"."value" AS "tag_name", "u"."email" as "user_email", COUNT(*) AS "number_assets" FROM "tag" "t"
  JOIN "tag_asset" "ta" ON "t"."id" = "ta"."tagsId" JOIN "asset" "a" ON "ta"."assetsId" = "a"."id" JOIN "user" "u" ON "a"."ownerId" = "u"."id"
  WHERE "a"."visibility" != 'hidden'
  GROUP BY "t"."value", "u"."email" ORDER BY "number_assets" DESC;

使用者

列出所有使用者

SELECT * FROM "user";

透過資產 ID 查詢擁有者資訊

SELECT "user".* FROM "user" JOIN "asset" ON "user"."id" = "asset"."ownerId" WHERE "asset"."id" = 'fa310b01-2f26-4b7a-9042-d578226e021f';

人物

刪除人物並解除所有臉部的關聯

DELETE FROM "person" WHERE "name" = 'PersonNameHere';

系統

設定

自訂設定

SELECT "key", "value" FROM "system_metadata" WHERE "key" = 'system-config';

(僅當未使用 設定檔案 時使用)

文件屬性

無縮圖

SELECT * FROM "asset" WHERE "asset"."previewPath" IS NULL OR "asset"."thumbnailPath" IS NULL;

檔案移動失敗

SELECT * FROM "move_history";

Postgres 內部操作

更改 DB_PASSWORD

ALTER USER <DB_USERNAME> WITH ENCRYPTED PASSWORD 'newpasswordhere';
