我有两列，我希望根据两者的比较基础获得输出。我的数据有点像：
Customer Id status
100 A
100 B
101 B
102 A
103 A
103 B
因此，客户可以拥有状态A或B或两者，我必须根据客户ID对状态进行细分。如果状态A和B然后返回高兴，如果只有A，则返回平均值，如果只有B返回悲伤。
答案 0 :(得分：0)
尝试以下查询，
SELECT DISTINCT Customer_Id,
(CASE WHEN COUNT(*) OVER(PARTITION BY Customer_Id) > 1 THEN 'happy'
WHEN Tstatus = 'A' THEN 'Avg'
ELSE 'Sad'END) AS New_Status
FROM @table1
GROUP BY Customer_Id,Tstatus
答案 1 :(得分：0)
如果客户ID和状态是唯一的组合 第1步：用例确定a或b

和步骤2将avg结果化为结果：像这样
SELECT customer id
,CASE WHEN avg(case when [status] ='A' then 0 else 2 end)
FROM [Your Table]
group by[customer id]
答案 2 :(得分：0)
我会这样做：
select customer_id,
(case when min(status) <> max(status) then 'happy'
when min(status) = 'A' then 'avg'
else 'sad'
end)
from t
where status in ('A', 'B')
group by customer_id
