Sequelize 기본 쿼리

const Op = Sequelize.Op;

Post.findAll({
  where: {
    authorId: 2
  }
});
// SELECT * FROM post WHERE authorId = 2

Post.findAll({
  where: {
    authorId: 12,
    status: 'active'
  }
});
// SELECT * FROM post WHERE authorId = 12 AND status = 'active';

Post.findAll({
  where: {
    [Op.or]: [{authorId: 12}, {authorId: 13}]
  }
});
// SELECT * FROM post WHERE authorId = 12 OR authorId = 13;

Post.findAll({
  where: {
    authorId: {
      [Op.or]: [12, 13]
    }
  }
});
// SELECT * FROM post WHERE authorId = 12 OR authorId = 13;

Post.destroy({
  where: {
    status: 'inactive'
  }
});
// DELETE FROM post WHERE status = 'inactive';

Post.update({
  updatedAt: null,
}, {
  where: {
    deletedAt: {

// UPDATE post SET updatedAt = null WHERE deletedAt NOT NULL;

Post.findAll({
