如何解决子查询返回超过1行

Question

我有这样的数据。 Data Table

我希望在时间范围内显示前10名消费（赚取积分）成员。 我的SQL：

SELECT  MOBILE,SUM(VALUE) as speding FROM crm_transaction  WHERE MOBILE IN (SELECT DISTINCT MOBILE FROM crm_transaction)

Answer 1

SELECT  MOBILE,SUM(VALUE) as speding
FROM crm_transaction  
WHERE MOBILE IN (SELECT DISTINCT MOBILE FROM crm_transaction)
group by mobile

Answer 2

这应该有效

select mobile, sum('value') as speding
from crm_transaction
where time_frame between '<time from>' and '<time to>'
group by mobile
order by speding desc limit 10

您需要将time_frame更改为存储时间的列的实际名称，更改＆lt;时间来自＆gt;和＆lt;时间到＆gt;达到你想要的时间价值。
