--- title: "Migrate from Sequelize to Drizzle" --- import Npm from "@mdx/Npm.astro"; import Steps from "@mdx/Steps.astro"; ## Getting Started This guide provides a straightforward approach to migrating a basic **Sequelize** project to **Drizzle ORM**. Although the example focuses on `PostgreSQL`, the process is similar for other supported databases. ### Overview of the migration process Regardless of your application type or API layer, the steps to transition from **Sequelize** to **Drizzle ORM** remain consistent: 1. Install **Drizzle ORM** & **Drizzle Kit** 2. Setup **Drizzle config** file 3. Introspect your database 4. Connect **Drizzle ORM** to your database 5. Transition your **Sequelize** queries to **Drizzle ORM** queries These steps are applicable whether you're developing a REST API (for example, with Express, Koa, or NestJS) or any other type of application that utilizes **Sequelize** for database interactions. ## Overview of the Sequelize project For this guide, we'll use a REST API built with `Express` as a sample project to migrate to **Drizzle ORM**. It has four entities: ```typescript collapsable copy filename="src/db/models/supplier.ts" import { DataTypes, Model } from 'sequelize'; import { Product } from './product'; import { sequelize } from '../db'; export class Supplier extends Model {} Supplier.init( { id: { type: DataTypes.INTEGER, autoIncrement: true, primaryKey: true, }, companyName: { type: DataTypes.TEXT, allowNull: false, }, city: { type: DataTypes.TEXT, allowNull: true, }, country: { type: DataTypes.TEXT, allowNull: false, }, }, { sequelize, tableName: 'suppliers', modelName: 'Supplier', timestamps: false, }, ); Supplier.hasMany(Product, { foreignKey: 'supplierId', }); Product.belongsTo(Supplier, { foreignKey: 'supplierId', targetKey: 'id', }); ``` ```typescript collapsable copy filename="src/db/models/product.ts" import { DataTypes, Model } from 'sequelize'; import { sequelize } from '../db'; export class Product extends Model {} Product.init( { id: { type: DataTypes.INTEGER, autoIncrement: true, primaryKey: true, }, name: { type: DataTypes.TEXT, allowNull: false, }, supplierId: { type: DataTypes.INTEGER, allowNull: false, references: { model: 'suppliers', key: 'id', }, field: 'supplierId', }, unitPrice: { type: DataTypes.DECIMAL, allowNull: false, }, unitsInStock: { type: DataTypes.INTEGER, allowNull: false, }, }, { sequelize, tableName: 'products', modelName: 'Product', timestamps: false, }, ); ``` ```typescript collapsable copy filename="src/db/models/order.ts" import { DataTypes, Model } from 'sequelize'; import { sequelize } from '../db'; export class Order extends Model {} Order.init( { id: { type: DataTypes.INTEGER, autoIncrement: true, primaryKey: true, }, orderDate: { type: DataTypes.DATE, allowNull: false, }, shippedDate: { type: DataTypes.DATE, allowNull: true, }, shipAddress: { type: DataTypes.TEXT, allowNull: false, }, shipPostalCode: { type: DataTypes.TEXT, allowNull: true, }, shipCountry: { type: DataTypes.TEXT, allowNull: false, }, }, { sequelize, tableName: 'orders', modelName: 'Order', timestamps: false, }, ); ``` ```typescript collapsable copy filename="src/db/models/order-detail.ts" import { DataTypes, Model } from 'sequelize'; import { sequelize } from '../db'; import { Order } from './order'; import { Product } from './product'; export class OrderDetail extends Model {} OrderDetail.init( { orderId: { type: DataTypes.INTEGER, primaryKey: true, references: { model: Order, key: 'id', }, field: 'orderId', }, productId: { type: DataTypes.INTEGER, primaryKey: true, references: { model: Product, key: 'id', }, field: 'productId', }, quantity: { type: DataTypes.INTEGER, allowNull: false, }, }, { sequelize, tableName: 'order_details', modelName: 'OrderDetail', timestamps: false, }, ); Order.hasMany(OrderDetail, { foreignKey: 'orderId', as: 'details' }); OrderDetail.belongsTo(Order, { foreignKey: 'orderId' }); Product.hasMany(OrderDetail, { foreignKey: 'productId', as: 'details' }); OrderDetail.belongsTo(Product, { foreignKey: 'productId' }); Order.belongsToMany(Product, { through: OrderDetail, foreignKey: 'orderId', as: 'products', targetKey: 'id', }); Product.belongsToMany(Order, { through: OrderDetail, foreignKey: 'productId', as: 'orders', targetKey: 'id', }); ``` The models have the following relations: 1. `one-to-many` between `Supplier` and `Product` 2. `many-to-many` between `Order` and `Product` For `many-to-many` relation we will create a join table `order_details`, so `Order` and `Product` entities will have `one-to-many` relations with `OrderDetail` entity. The corresponding tables have been created using Sequelize migration. Sequelize doesn't support auto generation of migrations, so you have to write them manually. ```javascript collapsable copy filename="src/db/migrations/20231220152726-init.js" 'use strict'; module.exports = { async up(queryInterface, Sequelize) { await queryInterface.createTable('suppliers', { id: { type: Sequelize.INTEGER, autoIncrement: true, primaryKey: true, }, companyName: { type: Sequelize.TEXT, allowNull: false, }, city: { type: Sequelize.TEXT, allowNull: true, }, country: { type: Sequelize.TEXT, allowNull: false, }, }); await queryInterface.createTable('products', { id: { type: Sequelize.INTEGER, autoIncrement: true, primaryKey: true, }, name: { type: Sequelize.TEXT, allowNull: false, }, supplierId: { type: Sequelize.INTEGER, allowNull: false, references: { model: 'suppliers', key: 'id', }, onUpdate: 'CASCADE', onDelete: 'SET NULL', }, unitPrice: { type: Sequelize.DECIMAL, allowNull: false, }, unitsInStock: { type: Sequelize.INTEGER, allowNull: false, }, }); await queryInterface.createTable('orders', { id: { type: Sequelize.INTEGER, autoIncrement: true, primaryKey: true, }, orderDate: { type: Sequelize.DATE, allowNull: false, }, shippedDate: { type: Sequelize.DATE, allowNull: true, }, shipAddress: { type: Sequelize.TEXT, allowNull: false, }, shipPostalCode: { type: Sequelize.TEXT, allowNull: true, }, shipCountry: { type: Sequelize.TEXT, allowNull: false, }, }); await queryInterface.createTable('order_details', { orderId: { type: Sequelize.INTEGER, primaryKey: true, references: { model: 'orders', key: 'id', }, onUpdate: 'CASCADE', onDelete: 'CASCADE', }, productId: { type: Sequelize.INTEGER, primaryKey: true, references: { model: 'products', key: 'id', }, onUpdate: 'CASCADE', onDelete: 'CASCADE', }, quantity: { type: Sequelize.INTEGER, allowNull: false, }, }); }, async down(queryInterface, Sequelize) { await queryInterface.dropTable('order_details'); await queryInterface.dropTable('orders'); await queryInterface.dropTable('products'); await queryInterface.dropTable('suppliers'); }, }; ``` This guide uses the following file structure: ```text 📦 ├ 📂 src │ ├ 📂 db │ │ ├ 📂 migrations │ │ │ └ 📜 20231220152726-init.js │ │ ├ 📂 models │ │ │ ├ 📜 order-detail.ts │ │ │ ├ 📜 order.ts │ │ │ ├ 📜 product.ts │ │ │ └ 📜 supplier.ts │ │ ├ 📜 db.ts │ │ └ 📜 config.js │ ├ 📂 routers │ │ ├ 📜 order.router.ts │ │ ├ 📜 product.router.ts │ │ └ 📜 supplier.router.ts │ ├ 📂 controllers │ │ ├ 📜 order.controller.ts │ │ ├ 📜 product.controller.ts │ │ └ 📜 supplier.controller.ts │ ├ 📜 index.ts │ └ 📜 server.ts ├ 📜 .sequelizerc ├ 📜 package.json └ 📜 tsconfig.json ``` #### Install Drizzle ORM & Drizzle Kit The first step is to install **Drizzle ORM** and `pg` package which we will use as a driver. The second step is to install **Drizzle Kit** and types for `pg`. [Drizzle Kit](/docs/kit-overview) - CLI companion for automatic SQL migrations generation and rapid prototyping. drizzle-orm pg -D drizzle-kit @types/pg #### Setup Drizzle config file **Drizzle config** - a configuration file that is used by **Drizzle Kit** and contains all the information about your database connection, migration folder and schema files. Create a `drizzle.config.ts` file in the root of your project and add the following content: ```typescript copy filename="drizzle.config.ts" import 'dotenv/config'; // make sure to install dotenv package import { defineConfig } from 'drizzle-kit'; export default defineConfig({ dialect: 'postgresql', out: './src/drizzle', schema: './src/drizzle/schema.ts', dbCredentials: { host: process.env.DB_HOST!, port: Number(process.env.DB_PORT!), user: process.env.DB_USERNAME!, password: process.env.DB_PASSWORD!, database: process.env.DB_NAME!, }, // Print all statements verbose: true, // Always ask for confirmation strict: true, }); ``` #### Introspect your database **Drizzle Kit** provides a CLI command to introspect your database and generate a schema file. The schema file contains all the information about your database tables, columns, relations, and indices. ```bash npx drizzle-kit introspect ``` This command will generate a schema.ts file, along with snapshots and migrations in the src/drizzle folder. ```typescript collapsable copy filename="src/drizzle/schema.ts" import { pgTable, varchar, serial, text, foreignKey, integer, numeric, timestamp, primaryKey, } from 'drizzle-orm/pg-core'; import { relations, sql } from 'drizzle-orm'; export const sequelizeMeta = pgTable('SequelizeMeta', { name: varchar('name', { length: 255 }).primaryKey().notNull(), }); export const suppliers = pgTable('suppliers', { id: serial('id').primaryKey().notNull(), companyName: text('companyName').notNull(), city: text('city'), country: text('country').notNull(), }); export const products = pgTable('products', { id: serial('id').primaryKey().notNull(), name: text('name').notNull(), supplierId: integer('supplierId') .notNull() .references(() => suppliers.id, { onDelete: 'set null', onUpdate: 'cascade' }), unitPrice: numeric('unitPrice').notNull(), unitsInStock: integer('unitsInStock').notNull(), }); export const orders = pgTable('orders', { id: serial('id').primaryKey().notNull(), orderDate: timestamp('orderDate', { withTimezone: true, mode: 'string' }).notNull(), shippedDate: timestamp('shippedDate', { withTimezone: true, mode: 'string' }), shipAddress: text('shipAddress').notNull(), shipPostalCode: text('shipPostalCode'), shipCountry: text('shipCountry').notNull(), }); export const orderDetails = pgTable( 'order_details', { orderId: integer('orderId') .notNull() .references(() => orders.id, { onDelete: 'cascade', onUpdate: 'cascade' }), productId: integer('productId') .notNull() .references(() => products.id, { onDelete: 'cascade', onUpdate: 'cascade' }), quantity: integer('quantity').notNull(), }, (table) => [ primaryKey({ columns: [table.orderId, table.productId], name: 'order_details_pkey' }) ] ); ``` ```sql collapsable copy filename="src/drizzle/0000_high_rhodey.sql" -- Current sql file was generated after introspecting the database CREATE TABLE IF NOT EXISTS "SequelizeMeta" ( "name" varchar(255) PRIMARY KEY NOT NULL ); --> statement-breakpoint CREATE TABLE IF NOT EXISTS "suppliers" ( "id" serial PRIMARY KEY NOT NULL, "companyName" text NOT NULL, "city" text, "country" text NOT NULL ); --> statement-breakpoint CREATE TABLE IF NOT EXISTS "products" ( "id" serial PRIMARY KEY NOT NULL, "name" text NOT NULL, "supplierId" integer NOT NULL, "unitPrice" numeric NOT NULL, "unitsInStock" integer NOT NULL ); --> statement-breakpoint CREATE TABLE IF NOT EXISTS "orders" ( "id" serial PRIMARY KEY NOT NULL, "orderDate" timestamp with time zone NOT NULL, "shippedDate" timestamp with time zone, "shipAddress" text NOT NULL, "shipPostalCode" text, "shipCountry" text NOT NULL ); --> statement-breakpoint CREATE TABLE IF NOT EXISTS "order_details" ( "orderId" integer NOT NULL, "productId" integer NOT NULL, "quantity" integer NOT NULL, CONSTRAINT order_details_pkey PRIMARY KEY("orderId","productId") ); --> statement-breakpoint DO $$ BEGIN ALTER TABLE "products" ADD CONSTRAINT "products_supplierId_fkey" FOREIGN KEY ("supplierId") REFERENCES "suppliers"("id") ON DELETE set null ON UPDATE cascade; EXCEPTION WHEN duplicate_object THEN null; END $$; --> statement-breakpoint DO $$ BEGIN ALTER TABLE "order_details" ADD CONSTRAINT "order_details_orderId_fkey" FOREIGN KEY ("orderId") REFERENCES "orders"("id") ON DELETE cascade ON UPDATE cascade; EXCEPTION WHEN duplicate_object THEN null; END $$; --> statement-breakpoint DO $$ BEGIN ALTER TABLE "order_details" ADD CONSTRAINT "order_details_productId_fkey" FOREIGN KEY ("productId") REFERENCES "products"("id") ON DELETE cascade ON UPDATE cascade; EXCEPTION WHEN duplicate_object THEN null; END $$; ``` Also, if you want to use relational queries, you have to update your schema file with relational tables: ```typescript copy filename="src/drizzle/schema.ts" // ...other imports import { relations } from 'drizzle-orm'; // ...other tables export const suppliersRelations = relations(suppliers, ({ many }) => ({ products: many(products), })); export const productsRelations = relations(products, ({ one, many }) => ({ supplier: one(suppliers, { fields: [products.supplierId], references: [suppliers.id] }), orderDetails: many(orderDetails), })); export const ordersRelations = relations(orders, ({ many }) => ({ orderDetails: many(orderDetails), })); export const orderDetailsRelations = relations(orderDetails, ({ one }) => ({ order: one(orders, { fields: [orderDetails.orderId], references: [orders.id] }), product: one(products, { fields: [orderDetails.productId], references: [products.id] }), })); ``` Now we have the following file structure: ```text 📦 ├ 📂 src │ ├ 📂 drizzle │ │ ├ 📂 meta | | | ├ 📜 _journal.json │ │ │ └ 📜 0000_snapshot.json │ │ ├ 📜 0000_lush_lenny_balinger.sql │ │ └ 📜 schema.ts │ ├ 📂 routers │ │ ├ 📜 order.router.ts │ │ ├ 📜 product.router.ts │ │ └ 📜 supplier.router.ts │ ├ 📂 controllers │ │ ├ 📜 order.controller.ts │ │ ├ 📜 product.controller.ts │ │ └ 📜 supplier.controller.ts │ ├ 📜 index.ts │ └ 📜 server.ts ├ 📜 package.json ├ 📜 drizzle.config.ts └ 📜 tsconfig.json ``` #### Connect Drizzle ORM to your database Create a `db.ts` file in the `src/drizzle` folder and set up your database configuration: ```typescript copy filename="src/drizzle/db.ts" import { drizzle } from 'drizzle-orm/node-postgres'; import { Client } from 'pg'; import * as schema from './schema'; export const client = new Client({ host: process.env.DB_HOST!, port: Number(process.env.DB_PORT!), user: process.env.DB_USERNAME!, password: process.env.DB_PASSWORD!, database: process.env.DB_NAME!, }); // { schema } is used for relational queries export const db = drizzle({ client, schema }); ``` ```typescript copy filename="src/index.ts" import 'dotenv/config'; import { client, db } from './drizzle/db'; import { resolve } from 'node:path'; import { migrate } from 'drizzle-orm/node-postgres/migrator'; (async () => { await client.connect(); // This command run all migrations from the migrations folder and apply changes to the database await migrate(db, { migrationsFolder: resolve(__dirname, './drizzle') }); // ... start your application })(); ``` #### Transition your Sequelize queries to Drizzle ORM queries In this section, we will show you how to replace several queries from **Sequelize** with **Drizzle ORM**. ##### Replace insert queries We will show how to insert new rows into `suppliers` and `products` tables. 1. `POST /suppliers` ```typescript copy filename="src/controllers/supplier.controller.ts" import { Supplier } from '../db/models/supplier'; const suppliers = await Supplier.bulkCreate([ { companyName: 'TestCompanyName1', city: 'TestCity1', country: 'TestCountry1', }, { companyName: 'TestCompanyName2', city: 'TestCity2', country: 'TestCountry2', }, ]); ``` With **Drizzle ORM**, the query is implemented as follows: ```typescript copy filename="src/controllers/supplier.controller.ts" import { db } from '../drizzle/db'; import { suppliers } from '../drizzle/schema'; await db.insert(suppliers).values([ { companyName: 'TestCompanyName1', city: 'TestCity1', country: 'TestCountry1', }, { companyName: 'TestCompanyName2', city: 'TestCity2', country: 'TestCountry2', }, ]); ``` 2. `POST /products` ```typescript copy filename="src/controllers/product.controller.ts" import { Product } from '../db/models/product'; const products = await Product.bulkCreate([ { name: 'TestProductName1', supplierId: 1, unitPrice: 10, unitsInStock: 20, }, { name: 'TestProductName2', supplierId: 1, unitPrice: 25, unitsInStock: 7, }, { name: 'TestProductName3', supplierId: 2, unitPrice: 50, unitsInStock: 17, }, { name: 'TestProductName4', supplierId: 2, unitPrice: 100, unitsInStock: 2, }, ]); ``` With **Drizzle ORM**, the query is implemented as follows: Be careful with the `unitPrice` field. In **Sequelize** it's a `number` type, but in **Drizzle ORM** it's a `string` type, which can handle more than 16383 digits after the decimal point, unlike the `number` type. ```typescript copy filename="src/controllers/product.controller.ts" await db.insert(products).values([ { name: 'TestProductName1', supplierId: 1, unitPrice: '10', unitsInStock: 20, }, { name: 'TestProductName2', supplierId: 1, unitPrice: '25', unitsInStock: 7, }, { name: 'TestProductName3', supplierId: 2, unitPrice: '50', unitsInStock: 17, }, { name: 'TestProductName4', supplierId: 2, unitPrice: '100', unitsInStock: 2, }, ]); ``` ##### Replace select queries In this section we will show how to select one row, multiple rows, count rows, filter rows, join tables and paginate results. 1. `GET /products/:id` In **Sequelize**, the response type is not strictly typed. For example, if you choose to include a relation or select only a few fields instead of all, these modifications will not be reflected in the response type. ```typescript copy filename="src/controllers/product.controller.ts" import { Product } from '../db/models/product'; import { Supplier } from '../db/models/supplier'; const { id } = req.params; const response = await Product.findByPk(id, { include: Supplier, }); ``` In **Drizzle ORM**, the query is implemented as follows: ```typescript copy filename="src/controllers/product.controller.ts" import { eq } from 'drizzle-orm'; import { db } from '../drizzle/db'; import { products, suppliers } from '../drizzle/schema'; const { id } = req.params; const response = await db .select({ product: products, supplier: suppliers, }) .from(products) .where(eq(products.id, id)) .leftJoin(suppliers, eq(suppliers.id, products.supplierId)); // or you can use relational queries const response = await db.query.products.findFirst({ where: (products, { eq }) => eq(products.id, id), with: { supplier: true, }, }); ``` In **Drizzle ORM**, the response type will match precisely what is specified in the select object, so including the `supplier` relation is fully type-safe. ```typescript // response type const response: { product: { name: string; id: number; supplierId: number; unitPrice: string; unitsInStock: number; }; supplier: { id: number; companyName: string; city: string | null; country: string; } | null; }[] ``` 2. `GET /products` In **Sequelize**, the result is not type-safe as it doesn't specify the fields you want to select. ```typescript copy filename="src/controllers/product.controller.ts" import { Product } from '../db/models/product'; import { Op } from 'sequelize'; const { rows, count } = await Product.findAndCountAll({ limit: 10, offset: 0, attributes: ['id', 'name', 'unitPrice', 'unitsInStock'], where: { name: { [Op.iLike]: `%test%`, }, }, }); ``` In **Drizzle ORM**, the query is implemented as follows: ```typescript collapsable copy filename="src/controllers/product.controller.ts" import { ilike, sql } from 'drizzle-orm'; import { db } from '../drizzle/db'; import { products } from '../drizzle/schema'; const whereOptions = ilike(products.name, `%test%`); const [response, count] = await Promise.all([ db .select({ id: products.id, name: products.name, unitPrice: products.unitPrice, unitsInStock: products.unitsInStock, }) .from(products) .where(whereOptions) .offset(0) .limit(10), db .select({ count: sql`cast(count(${products.id}) as integer)` }) .from(products) .where(whereOptions), ]); // or you can use relational queries const whereOptions = ilike(products.name, `%test%`); const [response, count] = await Promise.all([ db.query.products.findMany({ where: whereOptions, columns: { id: true, name: true, unitPrice: true, unitsInStock: true, }, offset: 0, limit: 10, }), db .select({ count: sql`cast(count(${products.id}) as integer)` }) .from(products) .where(whereOptions), ]); ``` In **Drizzle ORM**, the result is strictly type-safe, meaning the fields you select are explicitly defined. ```typescript // response type const response: { id: number; name: string; unitPrice: string; unitsInStock: number; }[] ``` 3. `GET /orders/:id` In **Sequelize** you can't implement complicated queries with methods like `findByPk`. So, you have to use raw queries, which are not type-safe as well. We want to select `id`, `orderDate` and `shipCountry` fields from `orders` table and by using `aggregation functions` sum `totalPrice` of order, `totalQuantity` of products in the order and count `totalProducts` in the order. ```typescript copy filename="src/controllers/order.controller.ts" import { sequelize } from '../db/db'; import { QueryTypes } from 'sequelize'; const { id } = req.params; const response = await sequelize.query( ` SELECT orders.id, orders."orderDate", orders."shipCountry", SUM(products."unitPrice" * order_details.quantity)::float AS "totalPrice", SUM(order_details.quantity)::int AS "totalQuantity", COUNT(order_details."productId")::int AS "totalProducts" FROM orders LEFT JOIN order_details ON orders.id = order_details."orderId" LEFT JOIN products ON order_details."productId" = products.id WHERE orders.id = :orderId GROUP BY orders.id `, { replacements: { orderId: id }, type: QueryTypes.SELECT, }, ); ``` In **Drizzle ORM**, the query is implemented as follows: ```typescript copy filename="src/controllers/order.controller.ts" import { eq, sql } from 'drizzle-orm'; import { db } from '../drizzle/db'; import { orders, orderDetails, products } from '../drizzle/schema'; const { id } = req.params; const response = await db .select({ id: orders.id, shipCountry: orders.shipCountry, orderDate: orders.orderDate, totalPrice: sql`cast(sum(${orderDetails.quantity} * ${products.unitPrice}) as float)`, totalQuantity: sql`cast(sum(${orderDetails.quantity}) as int)`, totalProducts: sql`cast(count(${orderDetails.productId}) as int)`, }) .from(orders) .where(eq(orders.id, id)) .groupBy(orders.id) .leftJoin(orderDetails, eq(orderDetails.orderId, orders.id)) .leftJoin(products, eq(products.id, orderDetails.productId)); ``` In **Drizzle ORM**, the result will be type-safe with aggregations too. ```typescript // response type const response: { id: number; shipCountry: string; orderDate: string; totalPrice: number; totalQuantity: number; totalProducts: number; }[] ``` **Note:** as of now aggregations are not supported in relational queries, so you have to use `core queries`. ##### Replace update queries In this section, we will show you how to update multiple rows. 1. `PATCH /suppliers/:id` ```typescript copy filename="src/controllers/supplier.controller.ts" import { Supplier } from '../db/models/supplier'; const { id } = req.params; const supplier = await Supplier.findByPk(1); if (!supplier) { throw new Error('Supplier not found'); } supplier.set({ city: 'TestCity1Updated', country: 'TestCountry1Updated', }); await supplier.save(); ``` In **Drizzle ORM**, the query is implemented as follows: ```typescript copy filename="src/controllers/supplier.controller.ts" import { eq } from 'drizzle-orm'; import { db } from '../drizzle/db'; import { suppliers } from '../drizzle/schema'; const { id } = req.params; await db .update(suppliers) .set({ city: 'TestCity1Updated', country: 'TestCountry1Updated', }) .where(eq(suppliers.id, id)); ``` ##### Replace delete queries In this section, we will show you how to delete a single row and multiple rows using transactions. 1. `DELETE /orders/:id` ```typescript copy filename="src/controllers/order.controller.ts" import { Order } from '../db/models/order'; import { OrderDetail } from '../db/models/order-detail'; import { sequelize } from '../db/db'; const { id } = req.params; try { const order = await Order.findByPk(id); if (!order) { throw new Error('Order not found'); } await sequelize.transaction(async (t) => { await OrderDetail.destroy({ where: { orderId: id, }, transaction: t, }); await order.destroy({ transaction: t }); }); } catch (e) { console.error(e); } ``` In **Drizzle ORM**, the query is implemented as follows: ```typescript copy filename="src/controllers/order.controller.ts" import { eq } from 'drizzle-orm'; import { db } from '../drizzle/db'; import { orderDetails, orders } from '../drizzle/schema'; const { id } = req.params; try { await db.transaction(async (tx) => { await tx.delete(orderDetails).where(eq(orderDetails.orderId, id)); await tx.delete(orders).where(eq(orders.id, id)); }); } catch (e) { console.error(e); } ```
