bulkUpdate in sequelize orm

Question

How can we implement bulkUpdate like bulkCreate in sequelize orm, I searched the whole documentation of sequelize but didn\'t find anything related to bulkUpdate, so I tried

Answer 1

You can, if you want to update a lot of records with the same values! example: I want to update field "activationStatus" for 10 users at 1 time, 1 user = 1 record in DB and I have Array of user IDs then:

User.update({ activationStatus: 'active'}, {
          where: {
              id: {
                  $in: [1,2,3,4,5,6,7,8,9,10]
              }
          }
      });

it will be analogue of SQL query:

UPDATE User SET activationStatus = 'active' WHERE id IN(1,2,3,4,5,6,7,8,9,10);

Use the bulkCreate to bulkUpdate method.

bulkCreate([...], { updateOnDuplicate: ["name"] })

updateOnDuplicate is an array of fields that will be updated when the primary key (or may be unique key) match the row. Make sure you have at least one unique field (let say id) in your model and in the dataArray both for upsert.
