我正在使用SQLServer2008。

SELECT  Amount ,
        OpportunityCloseDate
FROM    dbo.OpportunityMaster AS om

，输出为：

244254.00   Q3

在我的数据库中，年份从4月1日开始。我希望每季度获得这些数据。我不太了解季度。谢谢你的帮助..

Answer 1

我假设您想要对每个季度的数据求和：

;With Totals as (

    SELECT  SUM(Amount) as Total,
            DATEADD(quarter,DATEDIFF(quarter,0,OpportunityCloseDate),0) as RoundQuarter
    FROM    dbo.OpportunityMaster AS om
    GROUP BY
            DATEADD(quarter,DATEDIFF(quarter,0,OpportunityCloseDate),0)
)
select
    Total,
    DATEPART(year,RoundQuarter) -
       CASE WHEN DATEPART(quarter,RoundQuarter) = 1 THEN 1 ELSE 0 END as FinancialYear,
    CASE WHEN DATEPART(quarter,RoundQuarter) = 1 THEN 4
       ELSE DATEPART(quarter,RoundQuarter) - 1 END as FinancialQuarter
from
    Totals

DATEADD

这可以通过计算自1900-01-01 ¹以来发生的（整数）季度数，然后将相同数量的季度添加到1900-01-01 。这样可以将每个日期四舍五入到每个季度的第一天。

转换为datetime时，

¹ 0被视为1900-01-01。

在SQL Server中每季度获取数据
