示例代码：
操作步骤：
var fff
for (let info of data) {
fff = Math.floor(Math.random()*2);
var res = await db.collection('test').where({_id:info.uid}).update({view:dbCmd.inc(fff)})
if(res.updated){
console.log("更新成功",res);
}else{
console.log("更新失败",res);
}
}
var fff
for (let info of data) {
fff = Math.floor(Math.random()*2);
var res = await db.collection('test').where({_id:info.uid}).update({view:dbCmd.inc(fff)})
if(res.updated){
console.log("更新成功",res);
}else{
console.log("更新失败",res);
}
} 预期结果：
全部更新成功
全部更新成功
实际结果：
部分成功部分失败
部分成功部分失败
bug描述：
for循环内使用update更新数据，有的成功有的不成功
