Question

使用Teradata，我有一个数据，在一个列中有6个选项，我想要的是在一个单独的列中的六个选项中的每一个都有它有多少条目的计数，此刻我有6个单独的select个名称和一个在底部选中的一个加在一起，无论如何都要在一个声明中得到它

输出如下：

AgentName|emp_number|Manager_Empl_No| Hardware/Fault| Customer Experience| Prefer another Provider| Coverage/Serviceability| Costs Service| No Longer Required |Customer Usage
name 1| xxxx| xxxx |15| 27| 10| 3| 7| 22| 6
Name 2| xxxx| xxxx |19 |6 |29 |22 |10 |42 |4

我的代码是......

--- Hardware fault --- 
create volatile table hardware as
(
select
CSR_FirstName||' '||CSR_LastName as AgentName
,emp_number
,Manager_empl_no
,count(service) as "Hardware/Fault"
from ipshare.ORR_retention_database a
full join RMOIDS
on emp_number = Employee_No
where date_created between (sel start_date from startend_date) and (sel end_date from startend_date)
and referred_product = 'Mobile'
and decline_reason1 = 'Hardware/Fault'
group by (AgentName,emp_number,Manager_empl_no,decline_reason1)
qualify RANK() over (partition by AgentName order by AgentName DESC)=1
) 
with data on commit preserve rows;
sel * from hardware


--- Customer Experience --- 
create volatile table custex as
(
select

qualify RANK() over (partition by AgentName order by AgentName DESC)=1
) 
with data on commit preserve rows;

--Service no longer required
create volatile table snlr as

sel a.* 
,b."Customer Experience"
,c."Prefer another Provider"

from hardware a
inner join custex b

我还没有验证你想要完成的SQL的其余部分，但我相信你可以通过在聚合函数中使用CASE语句来消除多个volatile表并传递源表。

SELECT CSR_FirstName||' '||CSR_LastName as AgentName
     , emp_number
     , Manager_empl_no
     , COUNT(CASE WHEN Decline_Reason1 = 'Customer Experience' 
                  THEN Service 
                  ELSE NULL 
             END) AS CustomerExperinceCount_
     , COUNT(CASE WHEN Decline_Reason1 = /* {Next Reason} */
                  THEN Service
                  ELSE NULL
             END) AS NextReasonCount_
  FROM ipshare.ORR_retention_database a
  FULL JOIN
       RMOIDS
    ON emp_number = Employee_No
 WHERE date_created between (sel start_date from startend_date) 
                        and (sel end_date from startend_date)
   AND referred_product = 'Mobile'
 GROUP BY (AgentName,emp_number,Manager_empl_no,decline_reason1)
QUALIFY RANK() over (partition by AgentName order by AgentName DESC)=1

对列进行排序
