按类别显示db中的记录，并使用total计算状态

Question

我想按类别显示db中的记录并计算状态

假设我在数据库中有这些记录，

agent_tbl

    =========================
   | directors || status    |
    =========================
   |     AAA   || Suspended |
   |     BBB   || Deleted   |
   |     CCC   || Active    |
   |     AAA   || Deleted   |

这是我想要获得的结果：

Directors | Active | Suspended | Deleted |
------------------------------------------
AAA       |    0   |      1    |    1    |
------------------------------------------
BBB       |    0   |      0    |    1    |
------------------------------------------
CCC       |    1   |      0    |    0    |
------------------------------------------
Total          1          1         2    |
------------------------------------------   

这是我的查询

SELECT director,COUNT(*)  
FROM agent_tbl        
GROUP BY director;  

Answer 1

SELECT Directors,
       SUM(status = 'Active') AS Active,
       SUM(status = 'Suspended') AS Suspended,
       SUM(status = 'Deleted') AS Deleted
FROM agent_tbl
GROUP BY Directors

Answer 2

--For each director
select directors, 
count(case when status = 'Active' then 1 else null end) as 'Active',
count(case when status = 'Suspended' then 1 else null end) as 'Suspended',
count(case when status = 'Deleted' then 1 else null end) as 'Deleted'
from agent_tbl
group by directors
union
--Hard code for the total row
select 'Total',
count(case when status = 'Active' then 1 else null end) as 'Active',
count(case when status = 'Suspended' then 1 else null end) as 'Suspended',
count(case when status = 'Deleted' then 1 else null end) as 'Deleted'
from agent_tbl
