Question

我在SQL中有一个包含发票数据的表。我关心的唯一两列是金额和日期。我有几千行跨越几年

例如

19.32        2017-01-01 03:28:37.787

我的查询看起来像这样

SELECT * FROM (
  SELECT
    YEAR(CreatedUtc) AS [Year],
    MONTH(CreatedUtc) AS [Month], 
    DATENAME(MONTH, CreatedUtc) AS [Month Name],
    SUM(InvoiceTotal) as [InvoiceTotal]
  FROM [dbo].[Invoice]
  GROUP BY YEAR(CreatedUtc), MONTH(CreatedUtc), DATENAME(MONTH,CreatedUtc)
) AS t

PIVOT (
  SUM(InvoiceTotal) 
  FOR [Month Name] IN ([January],[February],[March],[April],[May],
    [June],[July],[August],[September],[October],[November],
    [December])) AS MNamePivot
ORDER BY 1,2

然而，我的结果很接近，但不完全是我想要的。我如何才能在一条线上每年获得12个月？

Year    Month   January February    March   April   May June    July    August  September   October November    December

2013    10  NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    NULL    3803.15 NULL    NULL

2014    6   NULL    NULL    NULL    NULL    NULL    32100.82    NULL    NULL    NULL    NULL    NULL    NULL

只需从MONTH(CreatedUtc) AS [Month]和SELECT移除GROUP BY，然后单独按年进行分组。事实上，按月进行分组是多余的，因为您在列中按其进行转换。

SELECT * FROM (
  SELECT
    YEAR(CreatedUtc) AS [Year],
    MONTH(CreatedUtc) AS [Month], 
    DATENAME(MONTH, CreatedUtc) AS [Month Name],
    SUM(InvoiceTotal) as [InvoiceTotal]
  FROM [dbo].[Invoice]
  GROUP BY YEAR(CreatedUtc), DATENAME(MONTH,CreatedUtc)
) AS t

PIVOT (
  SUM(InvoiceTotal) 
  FOR [Month Name] IN ([January],[February],[March],[April],[May],
    [June],[July],[August],[September],[October],[November],
    [December])) AS MNamePivot
ORDER BY 1,2
