问题描述
我们如何在sequelize orm中实现bulkUpdate,如bulkCreate,我搜索了 sequelize 的整个文档,但没有找到与 bulkUpdate 相关的任何内容,所以我尝试在for循环中循环更新,它可以工作,但是还有其他方法可以批量更新
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
推荐答案
使用 bulkCreate 到 bulkUpdate 方法.
Use the bulkCreate to bulkUpdate method.
bulkCreate([...], { updateOnDuplicate: ["name"] })
updateOnDuplicate
是一个字段数组,当主键(或可能是唯一键)匹配行时将更新这些字段.确保您的模型和 dataArray
中至少有一个唯一字段(比如说 id)用于 upsert.
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.
