Nodejs mongodb驱动程序部分更新

const { MongoClient } = require('mongodb');

async function main() {
  const uri = "your_mongodb_connection_string";
  const client = new MongoClient(uri);

  try {
    await client.connect();
    const database = client.db('your_database_name');
    const collection = database.collection('your_collection_name');

    // 更新单个文档
    const filter = { name: 'John Doe' };
    const update = { $set: { age: 30 } };
    const result = await collection.updateOne(filter, update);
    console.log(`${result.modifiedCount} document(s) was/were updated.`);

    // 更新多个文档
    const filterMany = { age: { $lt: 25 } };
    const updateMany = { $inc: { age: 1 } };
    const resultMany = await collection.updateMany(filterMany, updateMany);
    console.log(`${resultMany.modifiedCount} document(s) was/were updated.`);
  } finally {
    await client.close();
  }
}

main().catch(console.error);
