蜂巢sql：具有多个条件

Question

在具有count子句的情况下如何实现多个条件？例如case when prob=1 then having count(cust_id)<=3 or case when prob=0 then having count(cust_id)<=2

提前谢谢！

Answer 1

代替您似乎需要or条件的情况

 select  .. 
 from  ..  
 where ...
 group by prod...
 having prod=1 and count(cust_id)<=3
 OR prod=0 and count(cust_id)<=2

Answer 2

如果prod只是表中的一列，并且要通过“ count（cust_id）”来计算表中每个cust_id的出现次数，我将建议下一个解决方案：

select   cust_id
         , count(*)

from     <table_name>
where    prod=1
having   count(*) <= 3  

union

select   cust_id
         , count(*)

from     <table_name>
where    prod=0
having   count(*) <= 2
