+データベースにD1を使っており、 ut.code(); Learn でやっていた `npx prisma db push` とは手順が異なるので注意！

+```bash
+npx wrangler d1 migrations create my-code-db [migrationの名前]
+npx prisma migrate diff --from-local-d1 --to-scheme-datamodel ./prisma/schema.prisma --script --output ./migrations/000x_[migrationの名前].sql

+npx wrangler d1 migrations apply my-code-db --remote
