// 1. 先添加level字段（如果不存在）
db.user_info.updateMany(
  { level: { $exists: false } },
  { $set: { level: 0 } }
);
print("已初始化level字段");

// 2. 假设有两个服务器：s1和s2
// 更新服务器s1的玩家等级
var server1Db = db.getSiblingDB("m5_x1_game_10001");
var loginDb = db.getSiblingDB("x5_tk_login");

var count1 = 0;
server1Db.user.find().forEach(function(doc) {
  var result = loginDb.user_info.updateOne(
    { 
      _id: doc._id
    },
    { 
      $set: { 
        level: doc.playerManager.level,
        update_time: new Date()
      }
    }
  );
  
  if (result.modifiedCount > 0) {
    count1++;

print("服务器s1更新完成，更新了 " + count1 + " 条记录");
