+-- Migration pour ajouter ownerId aux tags
+-- Les tags existants seront assignés au premier utilisateur
+-- Cette version préserve les relations TaskTag existantes
+
+-- Étape 1: Ajouter la colonne ownerId temporairement nullable
+ALTER TABLE "tags" ADD COLUMN "ownerId" TEXT;
+
+-- Étape 2: Assigner tous les tags existants au premier utilisateur
+UPDATE "tags" 
+SET "ownerId" = (
+  SELECT "id" FROM "users" 
+  ORDER BY "createdAt" ASC 
+  LIMIT 1
+)
+WHERE "ownerId" IS NULL;
+
+-- Étape 3: Sauvegarder les relations TaskTag existantes avec les noms des tags
+CREATE TEMPORARY TABLE "temp_task_tag_names" AS 
+SELECT tt."taskId", t."name" as "tagName"
+FROM "task_tags" tt
+JOIN "tags" t ON tt."tagId" = t."id";
+
+-- Étape 4: Supprimer les anciennes relations TaskTag
+DELETE FROM "task_tags";
+
+-- Étape 5: Créer la nouvelle table avec ownerId non-nullable
+CREATE TABLE "new_tags" (
+    "id" TEXT NOT NULL PRIMARY KEY,
+    "name" TEXT NOT NULL,
+    "color" TEXT NOT NULL DEFAULT '#6b7280',
+    "isPinned" BOOLEAN NOT NULL DEFAULT false,
+    "ownerId" TEXT NOT NULL,
+    CONSTRAINT "new_tags_ownerId_fkey" FOREIGN KEY ("ownerId") REFERENCES "users" ("id") ON DELETE CASCADE ON UPDATE CASCADE
+);
+
+-- Étape 6: Copier les données des tags
+INSERT INTO "new_tags" ("id", "name", "color", "isPinned", "ownerId")
+SELECT "id", "name", "color", "isPinned", "ownerId" FROM "tags";
+
+-- Étape 7: Supprimer l'ancienne table
+DROP TABLE "tags";
+
+-- Étape 8: Renommer la nouvelle table
+ALTER TABLE "new_tags" RENAME TO "tags";
+
+-- Étape 9: Créer l'index unique pour (name, ownerId)
+CREATE UNIQUE INDEX "tags_name_ownerId_key" ON "tags"("name", "ownerId");
+
+-- Étape 10: Restaurer les relations TaskTag en utilisant les noms des tags
+INSERT INTO "task_tags" ("taskId", "tagId")
+SELECT tt."taskId", t."id" as "tagId"
+FROM "temp_task_tag_names" tt
+JOIN "tags" t ON tt."tagName" = t."name"
+WHERE EXISTS (
+  SELECT 1 FROM "tasks" WHERE "tasks"."id" = tt."taskId"

+-- Étape 11: Nettoyer la table temporaire
+DROP TABLE "temp_task_tag_names";
