Select 全部为逗号分隔字符串的数据

Question

我有一个 table 的条件，例如

id   condition   member-id
 1    Fall         A1452
 2    Fall         A1453
 3    Dementia     A1452
 4    Dementia     A1453
 5    Fall         A1450
 6    Headaches    A1453

现在我想要的是将条件作为参数传递，例如 "Fall,Dementia" 我想要那些同时具有 Fall 和 Dementia condition

的会员 ID

select * from conditions where condition IN('Fall,Dementia')

这 return 3 条记录，但我需要两者都有的记录？

记住 "Fall,Dementia" 是动态的，它可能会更改为 "Fall,Dementia,Headaches"

Answer 1

使用条件聚合

 select MemberId from 
 conditions
 where condition IN('Fall','Dementia')
 group by MemberId
 having count(distinct condition )=2

Answer 2

 select distinct MemberId 
 from Whosebug4
 where Condition in ('Fall','Dementia')
 group by memberId
 having count(MemberId)=2
