An example of an AI chatbot conversation about Sequelize querying basics.
What are the basics of querying with Sequelize?
Sequelize is an ORM for Node.js that allows you to interact with SQL databases. Basic querying involves methods like findAll, findOne, and create. Would you like to know more about a specific method?
Can you explain how to use findAll?
Sure! The findAll method retrieves all records from a specified model. You can also pass options to filter, sort, or limit the results. For example: Model.findAll({ where: { active: true } }).
What options can I use with findAll?
You can use options like where, order, limit, and offset. For instance, order: [['createdAt', 'DESC']] will sort the results by the createdAt field in descending order.
How do I handle errors when querying?
You can use try-catch blocks or promise .catch() methods to handle errors. For example: Model.findAll().catch(err => console.error(err));.
