Question

我想要一个只在工作日执行的条件，变量@Executedate是int类型，只占用datetime的日期部分，如果@Executeday是星期六或星期日，它应该重置为星期一。

这是一段代码，

Declare @Executeday int      

declare @time varchar(200)

set @time =  convert(varchar(8), getdate(), 108)

if day(getdate()) < 16                          
begin 

set @Executeday = (select top 1 Description from cts_configuration(nolock) where name like 'ReminderMailerFirstFortNightDay')

end
else                          
begin         
set @Executeday = (select top 1 Description from cts_configuration(nolock) where name like 'ReminderMailerSecondFortNightDay')

 end

if (day(getdate())=@Executeday) or (day(getdate())=@Executeday+2) or (day(getdate())=@Executeday+4)

begin

if(@time between '10:00:00' and '11:00:00') 
begin

我想在这里使用if条件......（如果它是坐着或太阳，那将@executeday重置为星期一）

Answer 1

DECLARE @ExecuteDay AS int = 7;

DECLARE @Today AS date = GETDATE();
DECLARE @ExecuteDate AS date = DATEADD(day, @ExecuteDay - DATEPART(day, @Today), @Today);
DECLARE @WeekDay AS int = (@@DATEFIRST + DATEPART(WEEKDAY, @ExecuteDate)) % 7;

IF @WeekDay IN (0, 1)
    SET @ExecuteDate = DATEADD(day, 2 - @WeekDay, @ExecuteDate)

PRINT @ExecuteDate

if条件仅在工作日执行，即mon-fri
