How do I perform complex queries using Sequelize?

You can use Sequelize's query methods like findAll, findOne, and where to perform complex queries. What specific query are you trying to build?

I want to find all users who have made more than 5 orders.

You can achieve that with a query like this: User.findAll({ where: { ordersCount: { [Op.gt]: 5 } } });. Make sure to replace ordersCount with the actual field name.

What if I want to include the orders in the result?

You can use the include option to fetch associated models. For example: User.findAll({ include: [{ model: Order }], where: { ordersCount: { [Op.gt]: 5 } } });.

Can I sort the results by the number of orders?

Yes, you can add an order clause like this: User.findAll({ include: [{ model: Order }], where: { ordersCount: { [Op.gt]: 5 } }, order: [['ordersCount', 'DESC']] });.
