使用运算符IN的Golang MongoDB更新查询

package main

import (
    "context"
    "fmt"
    "log"

    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
    "go.mongodb.org/mongo-driver/bson"
)

func main() {
    // 创建MongoDB客户端
    clientOptions := options.Client().ApplyURI("mongodb://localhost:27017")
    client, err := mongo.Connect(context.Background(), clientOptions)
    if err != nil {
        log.Fatal(err)
    }

    // 获取数据库和集合
    db := client.Database("mydatabase")
    collection := db.Collection("mycollection")

    // 更新查询
    filter := bson.M{"name": bson.M{"$in": []string{"John", "Doe"}}}
    update := bson.M{"$set": bson.M{"status": "active"}}
    updateResult, err := collection.UpdateMany(context.Background(), filter, update)
    if err != nil {
        log.Fatal(err)
    }

    fmt.Printf("Updated %d documents\n", updateResult.ModifiedCount)
}
