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

You can perform advanced queries in Sequelize by using methods like findAll, findOne, and including options like where, include, and order.

Can you give me an example of a complex query with multiple conditions?

Sure! Here's an example: User.findAll({ where: { age: { [Op.gt]: 18 }, status: 'active' }, include: [{ model: Post, where: { published: true } }] }); This fetches active users over 18 with published posts.

What if I want to paginate the results?

You can paginate results by using the limit and offset options. For example: User.findAll({ limit: 10, offset: 20 }); will get the third page of results assuming 10 results per page.

How do I handle errors in Sequelize queries?

You can handle errors using try-catch blocks in async functions or by using .catch() with promises. For example: User.findAll().then(...).catch(err => console.error(err));.
