尋找有1個以上訂單的學校

我想找出所有同一學校有1個以上訂單的學校。在下面的例子中，我想找到學校沒有2尋找有1個以上訂單的學校

| school_ucn | order_no | 
----------------------------- 
| 1    | 101  | 
| 1    | 101  | 
| 2    | 102  | 
| 2    | 102  | 
| 2    | 103  | 
| 2    | 103  |

如果查詢是這樣的：

select 
    school_ucn, count(otc_order_number) 
from storiacloud.schl_storia_revenue_fact 
group by 
    otc_order_number, school_ucn 
having count(otc_order_number) > 1

從GROUPBY取出訂單號

select 
    school_ucn,count(DISTINCT otc_order_number) 
from 
    storiacloud.schl_storia_revenue_fact 
group by 
    school_ucn 
having 
    count(distinct otc_order_number)>1

我會用'COUNT（DISTINCT otc_order_number）'，基於OP的期望輸出。 –
