如何计算下周六到下周六的可用周日？ [英] How to calculate the next available Sunday to the following Saturday?

问题描述

我正在编写一个sql查询，我正在尝试确定下一个可用的星期日上午12:00到下周六晚上11:59，我有以下查询：


选择dateadd（dd，（（datediff（dd，'''17530107''，MAX（payrolldate））/ 7）* 7）+7，''17530107''）AS [星期日]来自dbo.payroll

其中payrollran =''不''


这给了我下一个星期天没有时间，但我仍然没有接下来的星期六。有人可以帮忙吗？


谢谢

解决方案

减法结果一分钟。

Rabbit，


我只得到一个结果，我需要两个。一个用于下一个星期日，第二个结果应该是下一个星期六。

对于星期日之后的星期六，采取星期日的日期时间，增加7天，减去一分钟。

I am writing a sql query and I''m trying to determine the next available Sunday at 12:00 AM through the next Saturday 11:59 PM and I have the following query:

select dateadd(dd, ((datediff(dd, ''17530107'', MAX(payrolldate))/7)*7)+7, ''17530107'') AS [Sunday] from dbo.payroll
where payrollran = ''No''

That gives me the next available Sunday with no time but I still don''t have the following Saturday. Can someone please assist?

Thank you

Doug

解决方案

Subtract a minute from the result.

Rabbit,

I''m only getting one result, and I need two. One for the next Sunday, and the second result should be the following Saturday.

For the saturday following the sunday, take the sunday datetime, add 7 days, subtract one minute.
