sql - 事件过滤器的 SQL Server 查询

Question

我们确实有一个表事件并使用以下列存储事件

EventID INT
EventName VARCHAR(50)
BeginMonth TINYINT
BeginDay TINYINT
EndMonth TINYINT
EndDay TINYINT

下面是一些例子records

EventID EventName  BeginMonth BeginDay EndMonth EndDay
  1      Event-1     3           1        6      17
  2      Event-2     5           10       8      15
  3      Event-3     11           5       2      13

请注意：我们不存储年份值，因为事件每年都会发生，因此 endmonth 可能小于 beginmonth（记录号 3）。这意味着活动从一年开始，到下一年结束

现在我想要一个 ms sql 查询，它应该根据当前日期给出所有事件。如果我们不使用年份作为当前日期会很好。

如果我的问题正确，以下内容Query对您有用。

Select *

FROM Events
WHERE --CONVERT(DATE,GETDATE()) BETWEEN
CONVERT(date,dateadd(day,datediff(day,1,GETDATE()),0)) BETWEEN
CAST((CAST(case when CAST([BeginMonth] as Varchar)> (select datepart(month,getdate())) 
THEN (select datepart(YEAR,getdate())-1)
when CAST([BeginMonth] as Varchar)= (select datepart(month,getdate()))
AND CAST([BeginDay] as Varchar)> (select datepart(month,getdate()))
THEN (select datepart(YEAR,getdate())-1)
when CAST([BeginMonth] as Varchar)= (select datepart(month,getdate()))
AND CAST([BeginDay] as Varchar)= (select datepart(month,getdate()))
THEN (select datepart(YEAR,getdate()))
when CAST([BeginMonth] as Varchar)= (select datepart(month,getdate()))
AND CAST([BeginDay] as Varchar)< (select datepart(month,getdate()))
THEN (select datepart(YEAR,getdate())) 
ELSE (select datepart(YEAR,getdate())) END AS VARCHAR)
+'-'+
CAST([BeginMonth] as Varchar)
+'-'+
CAST([BeginDay] as Varchar)) as DATE) 
AND
CAST((CAST(case when CAST([BeginMonth] as Varchar)> (select datepart(month,getdate())) 
THEN (select datepart(YEAR,getdate())-1)
when CAST([BeginMonth] as Varchar)= (select datepart(month,getdate()))
AND CAST([BeginDay] as Varchar)> (select datepart(month,getdate()))
THEN (select datepart(YEAR,getdate())-1)
when CAST([BeginMonth] as Varchar)= (select datepart(month,getdate()))
AND CAST([BeginDay] as Varchar)= (select datepart(month,getdate()))
THEN (select datepart(YEAR,getdate()))
when CAST([BeginMonth] as Varchar)= (select datepart(month,getdate()))
AND CAST([BeginDay] as Varchar)< (select datepart(month,getdate()))
THEN (select datepart(YEAR,getdate())) 
ELSE (select datepart(YEAR,getdate()))+1 END AS VARCHAR)
+'-'+
CAST([BeginMonth] as Varchar)
+'-'+
CAST([BeginDay] as Varchar)) as DATE)

我得到了我的Mistake.

Select *

WHERE CONVERT(DATE,GETDATE()) BETWEEN

CAST((CAST(case when CAST([BeginMonth] as Varchar)> (select datepart(month,getdate()))

THEN (select datepart(YEAR,getdate())-1)
when CAST([BeginMonth] as Varchar)= (select datepart(month,getdate()))
AND CAST([BeginDay] as Varchar)= (select datepart(month,getdate()))
THEN (select datepart(YEAR,getdate()))

我希望这一次你会满意。

如果您不想使用Today'sDate 并且您有Predefined日期，请替换GETDATE()为您的predefinedDatetime 值。

是的，它Datetime
