SQL 서버 - 월별 선택 쿼리 결과 정렬

Question

데이터 볼륨 (이 경우 호출)을 수집 한 다음 월별로 정렬하는 다음과 같은 쿼리 (및 몇 가지 매우 유사한 쿼리)가 있습니다.

그것은 잘 작동하고 내가 필요로하는 결과를 출력합니다,하지만 난이 일을 더 실용적인/짧은 방법이 있어야이 느낌이 : 당신이 줄 수있는 팁

SELECT 
sum(case when datepart(mm,calldate) = '1' THEN 1 ELSE 0 END) AS 'JAN', 
sum(case when datepart(mm,calldate) = '2' THEN 1 ELSE 0 END) AS 'FEB', 
sum(case when datepart(mm,calldate) = '3' THEN 1 ELSE 0 END) AS 'MAR', 
sum(case when datepart(mm,calldate) = '4' THEN 1 ELSE 0 END) AS 'APR', 
sum(case when datepart(mm,calldate) = '5' THEN 1 ELSE 0 END) AS 'MAY', 
sum(case when datepart(mm,calldate) = '6' THEN 1 ELSE 0 END) AS 'JUN', 
sum(case when datepart(mm,calldate) = '7' THEN 1 ELSE 0 END) AS 'JUL', 
sum(case when datepart(mm,calldate) = '8' THEN 1 ELSE 0 END) AS 'AUG', 
sum(case when datepart(mm,calldate) = '9' THEN 1 ELSE 0 END) AS 'SEP', 
sum(case when datepart(mm,calldate) = '10' THEN 1 ELSE 0 END) AS 'OCT', 
sum(case when datepart(mm,calldate) = '11' THEN 1 ELSE 0 END) AS 'NOV', 
sum(case when datepart(mm,calldate) = '12' THEN 1 ELSE 0 END) AS 'DEC' 

FROM [Telephony].[dbo].[tbl_Outbound] 

WHERE source like '132%' 
     and duration > 300 

    union all 

SELECT

    FROM [Telephony].[dbo].[tbl_Outbound] 

    WHERE source like '132%' 

감사합니다 :)

Answer 1

나는 다음과 같이 작동한다고 믿는다. 이 기능은 SQL Server의 피벗 기능을 사용합니다.

SELECT rowName,[January],[February],[March],[April],[May],[June],[July],[August],[September],[October],[November],[December] 
FROM (
    SELECT 
     "Duration>300" as rowName, 
     datename(month, calldate) as MonthName, 
     Count(*) as recordCount 

    FROM 
     [Telephony].[dbo].[tbl_Outbound] 
    WHERE source like '132%' 
     and duration > 300 
    UNION ALL 
    SELECT 
     "AllDurations" as rowName, 
     datename(month, calldate) as MonthName, 
     Count(*) as recordCount 

    FROM 
     [Telephony].[dbo].[tbl_Outbound] 
    WHERE source like '132%' 
) as SourceTable 
PIVOT 
(
    Sum(recordCount) 
    FOR MonthName in ([January],[February],[March],[April],[May],[June],[July],[August],[September],[October],[November],[December]) 
) AS PivotTable
