使用mongo遇到一些需要查询的符合要求的数据，写sql

1.修改符合条件的数据

如果一个值在A数组中存在，那么修改该数据中B数组，只保留B数组中xxx

db.user.find({account:"csbj"}).pretty()
{
        "_id" : ObjectId("6139680bde8bcd0001beb194"),
        "id" : 813,
        "account" : "csbj",
        "password" : "983d511534abdcbfc3b457c24f8cb1f2",
        "name" : "csbj",
        "sex" : 1,
        "status" : 2,
        "tel" : "",
        "phone" : "",
        "resetPWD" : 2,
        "MediaFusionUser" : false,
        "mediaCodes" : [
                "xww",
                "wb",
                "zmdkks",
                "cxzx"
        ],
        "mediaRoleCodes" : [
                "wbgly",
                "wzgly"
        ],
        "roleCodes" : [
                &#
