sql查询需要在单行中分组列

Question

我有以下表结构

TicketID    Status  Duration
-----------------------------
1234           8        2
1233           8       10
1232           4        5
1231           8       12
1230           4       50

• 状态8表示已关闭
• 状态4表示打开

需要以下列方式输出。请只做那些需要的。如果可能的话，我想在单个SQL查询中使用它。

请帮我按以下方式输出。

Row     Closed (sum)    Open(Sum)
---------------------------------
   1       24              55

Answer 1

select 1 as row, 
       sum(case when status = 8 then 1 else 0 end) as closed,
       sum(case when status = 4 then 1 else 0 end) as open
from your_table

Answer 2

select 
1 as Row,
sum(case when Status=8 then 1 else 0 end  ) as Closed_Sum,
sum(case when Status=4 then 1 else 0 end  ) as Open_Sum
  from 
Mytable
