Question

我的表格中的条目将包含这样的数据日期：

Date          Value
4-20-2014     45
4-21-2014     15
4-22-2014     35
...
4-30-2014     109

我将在每个星期日执行我的存储过程，这意味着我希望从上周日到昨天（星期六）获得Date行。

我有以下查询，从上周日到上周六，我认为这是错误的，所以我将其修改如下：

INSERT INTO [database].[dbo].[table]
SELECT (WEEKENDING DATE) AS [Date], SUM([ORDERS]) AS Orders, SUM([B ORDERS]) AS bOrders, SUM([RESULT]) AS Results
FROM [database].[dbo].[origtable]
WHERE
    [Date] >= "PREVIOUS SUNDAY DATE"
    AND
    [Date] <= "SATURDAY DATE (YESTERDAY)"

我想通过以下方式获得一些帮助：

    [Date] >= "PREVIOUS SUNDAY DATE"
    AND
    [Date] <= "SATURDAY DATE (YESTERDAY)"

因此，如果我在5/4/2014上运行SP，则会在星期日（4/27/2014）到星期六（5/3/2014）之间抓取

这会起作用吗？

INSERT INTO [Database].[dbo].[table]
SELECT 
    CONVERT(VARCHAR(10), GETDATE(), 101) AS [Date], 
    SUM([EMR ORDERS]) AS LastWeekEMROrders, 
    SUM([ACCESSIONED LAB ORDERS]) AS LastWeekAccLabOrders, 
    SUM([LAB_RESULT]) AS LastWeekLabResults
FROM [database].[dbo].[origtable]
WHERE
    [Date] >= DATEADD(day, -((DATEPART(dw, GETDATE()) + @@DATEFIRST) % 7) - 6,
              DATEADD(dd, DATEDIFF(dd, 0, GETDATE()), 0)) --PREVIOUS SUNDAY
    AND
    [Date] <= DATEADD(day, -(DATEPART(dw, GETDATE()) + @@DATEFIRST) % 7,
              DATEADD(dd, DATEDIFF(dd, 0, GETDATE()), 0)) --PREVIOUS SATURDAY

如果我有以下查询并在2014年5月4日执行它：

set @startdate = DATEADD(wk, DATEDIFF(wk, 0, getdate()), -2) --for sunday
set @enddate = DATEADD(wk, -1, DATEADD(wk, DATEDIFF(wk, 0,getdate()), -1))-- for saturday

周日和周六的约会对象是什么？

尝试以下修改过的查询：

修改：该查询已进一步修改为不使用DATEFROMPARTS。

INSERT INTO [Database].[dbo].[table] SELECT CONVERT(VARCHAR(10), GETDATE(), 101) AS [Date], SUM([EMR ORDERS]) AS LastWeekEMROrders, SUM([ACCESSIONED LAB ORDERS]) AS LastWeekAccLabOrders, SUM([LAB_RESULT]) AS LastWeekLabResults FROM [database].[dbo].[origtable] WHERE [Date] >= DATEADD(d, -8, DATEADD(dd, DATEDIFF(dd,0, current_timestamp), 0)) --PREVIOUS SUNDAY AND [Date] <= DATEADD(d, -1, DATEADD(dd, DATEDIFF(dd,0, current_timestamp), 0)) --PREVIOUS SATURDAY;
