需要从具有相同数据的行中消除null

Question

我的数据： -

UserId |ShopId  |PlanName
------------------------
241    | 17679  |NULL
241    | 20037  |NULL
241    | 20037  |440

我需要的数据： -

UserId |ShopId  |PlanName
------------------------
241    | 17679  |NULL
241    | 20037  |440

这是我的查询

select distinct so.UserId,so.ShopId, (select sa1.beatplanid from beatplansetting bps1 
inner join shopassign sa1 on bps1.beatplanid = sa1.beatplanid
where
so.shopid = bps1.shopid
and
sa.userid = sa1.userid
) as PlanName from 
shopinandoutlog so
left join beatplansetting bps on so.shopid = bps.shopid
left join shopassign sa on so.userid = sa.userid and bps.beatplanid = sa.beatplanid
where so.userid=241
and
convert(varchar,mobiletransactiondate,106)='01 oct 2016'
and
so.shopid in (20037,17679)

Answer 1

我认为这可以满足您的需求：

select UserId, ShopId, MAX(PlanName) as PlanName
from t
group by UserId, ShopId;

我不知道您的查询与实际问题有什么关系。您的查询具有查询或示例数据中未提及的多个表和列。
