SQL Server-按月排列选择查询结果

我有以下查询（以及其他几个非常类似的查询），它收集大量数据（在本例中是调用），然后按月进行排列

它工作正常，输出我需要的结果，但我觉得必须有一种更实用/更短的方法：

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
 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%'

感谢您提供的任何提示：）

我相信以下方法会奏效。这将使用SQL Server的透视功能：

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

你真的不在乎calldate是在2014年还是2013年？这相当冗长，但冗长似乎是因为需要交叉表/轴心样式的输出，而在月份计数时则更少。你可以在没有联合的情况下在一个查询中完成这一切，但它看起来同样丑陋。Lamak-此表仅包含12个月的滚动数据，因此在本例中为noJNevill-需要此格式是因为我在excel中将此查询作为数据连接，因此，数据以我需要的格式显示出来，因为我有几个这样的查询，它们填充了一个数据表。@Uberzeni；如果您希望更改答案的意图/功能，请添加注释，而不是直接编辑。编辑仅用于修改/改进答案，不改变意图。谢谢！我不知道你能做到，这真的很有帮助！我所做的所有调整都是通过calldate添加到一个组中，并在rowname后面添加一个缺少的逗号，这对于没有服务器来测试这一点来说并不坏！
