问题
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 to loop update in for loop, it works but is there any other way to update in bulk
回答1:
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.
