Question

@status [nvarchar](max),
@fromDate [datetime],
@toDate [datetime],
@companyId [int]
select  
ISNULL(SUM(rec.SubTotal), 0) AS SubTotal,
sto.Id AS StoreId,
    CAST(rec.CreatedDate AS DATE) as CreatedDate,
    sto.Name AS StoreName from Receipts rec
                        left join(
                            select  ReceiptId, SUM(Quantity) as Quantity from ReceiptDetails
                            group by ReceiptId
                        ) red on rec.Id = red.ReceiptId
                        left outer join(
                            select Id,Name from Stores
                            group by Id,Name
                        ) sto on rec.StoreId = sto.Id
                         where rec.CompanyId = @companyId
                            and rec.Status = @status
                            and rec.CreatedDate <= @todate
                            and rec.CreatedDate >=  @fromDate
group by sto.Id, sto.Name,CAST(rec.CreatedDate AS DATE)

这是我当前的查询SQL，目前，我每天通过@todate和@fromdate选择一个rangeDate中的数据

现在，我想按过去7周的日期按CreatedDate选择数据， @fromdate是Today的示例：2018-12-1 预期的数据将是

我目前的数据

...
...
2018-11-29
2018-11-30
2018-12-1

我的意思是6周前的日期

您可以将其创建为函数，并传入星期数，但这取决于您。

参见下文：

declare @i as int
set @i = 7
select  
    ISNULL(SUM(rec.SubTotal), 0) AS SubTotal,
    sto.Id AS StoreId,
    case 
        when CAST(rec.CreatedDate as Date) between CAST(rec.CreatedDate AS DATE) -(7 * (@i)) and CAST(rec.CreatedDate AS DATE) -((7*(@i - 1)) + 1)
            then 
                Cast(CAST(rec.CreatedDate -(7*(@i)) AS DATE))
        when CAST(rec.CreatedDate as Date) between CAST(rec.CreatedDate AS DATE) -(7 * (@i-1)) and CAST(rec.CreatedDate AS DATE) -((7*(@i-2)) + 1)
            then 
                Cast(CAST(rec.CreatedDate AS DATE) -(7*(@i-1)) AS DATE)
        when CAST(rec.CreatedDate as Date) between CAST(rec.CreatedDate AS DATE) -(7 * (@i - 2)) and CAST(rec.CreatedDate AS DATE) -((7*(@i-3)) + 1)
            then 
                Cast(CAST(rec.CreatedDate AS DATE) -(7*(@i-2)) AS DATE)
        when CAST(rec.CreatedDate as Date) between CAST(rec.CreatedDate AS DATE) -(7 * (@i - 3)) and CAST(rec.CreatedDate AS DATE) -((7*(@i-4)) + 1)
            then 
                Cast(CAST(rec.CreatedDate AS DATE) -(7*(@i-3)) AS DATE)
        when CAST(rec.CreatedDate as Date) between CAST(rec.CreatedDate AS DATE) -(7 * (@i - 4)) and CAST(rec.CreatedDate AS DATE) -((7*(@i-5)) + 1)
            then 
                Cast(CAST(rec.CreatedDate AS DATE) -(7*(@i-4)) AS DATE)
        when CAST(rec.CreatedDate as Date) between CAST(rec.CreatedDate AS DATE) -(7 * (@i - 5)) and CAST(rec.CreatedDate AS DATE) -((7*(@i-6)) + 1)
            then 
                Cast(CAST(rec.CreatedDate AS DATE) -(7*(@i-5)) AS DATE)
        when CAST(rec.CreatedDate as Date) between CAST(rec.CreatedDate AS DATE) -(7 * (@i - 6)) and CAST(rec.CreatedDate AS DATE) -((7*(@i-7)) + 1)
            then 
                Cast(CAST(rec.CreatedDate AS DATE) -(7*(@i-6)) AS DATE)
        else ''
    end as CreatedDate,
    sto.Name AS StoreName 
from Receipts rec
                    left join(
                        select  ReceiptId, SUM(Quantity) as Quantity from ReceiptDetails
                        group by ReceiptId
                    ) red on rec.Id = red.ReceiptId
                    left outer join(
                        select Id,Name from Stores
                        group by Id,Name
                    ) sto on rec.StoreId = sto.Id
                     where rec.CompanyId = @companyId
                        and rec.Status = @status
                        and rec.CreatedDate <= @todate
                        and rec.CreatedDate >=  @fromDate
group by sto.Id, sto.Name,CAST(rec.CreatedDate AS DATE)

选择7周前的7天
