How can I perform advanced queries using an ORM in Node.js?

You can use libraries like Sequelize or TypeORM to perform advanced queries. What specific query are you looking to implement?

I want to filter results based on multiple conditions and include related models.

In Sequelize, you can use the include option to fetch related models and the where clause for filtering. Would you like a code example?

Yes, please provide a code example for that.

Sure! Here's a basic example:

const users = await User.findAll({
  where: { age: { [Op.gt]: 18 } },
  include: [{ model: Profile, where: { active: true } }]
});

This fetches users over 18 with active profiles.

That makes sense! Can I also sort the results?

Absolutely! You can add an order option to your query. For example:

const users = await User.findAll({
  where: { age: { [Op.gt]: 18 } },
  include: [{ model: Profile, where: { active: true } }],
  order: [['createdAt', 'DESC']]
});

This will sort the results by creation date in descending order.
