我正在使用 c# 和 sql 在 MVC4 中做我的项目。我有一个MemberDetails包含表的表

CREATE TABLE [dbo].[MemberDetails] (
[Id]          INT           IDENTITY (1, 1) NOT NULL,
[Mem_FirstNA] VARCHAR (100) NOT NULL,
[Mem_LastNA]  VARCHAR (100) NOT NULL,
[Mem_Occ]     VARCHAR (100) NOT NULL,
[Mem_DOB]     DATETIME      NOT NULL,
[Mem_Email]   VARCHAR (50)  NOT NULL,
PRIMARY KEY CLUSTERED ([Id] ASC)
 );

我只想选择未来 30 天内的生日的姓名和出生日期，我使用以下查询

SELECT 
    Mem_FirstNA, Mem_LastNA, Mem_DOB 
FROM 
    MemberDetails 
WHERE 
    Mem_DOB >= getdate() - 1 AND Mem_DOB <= getdate() + 30

对吗，我选择了 0 个项目，我使用下表。

FROM 
    MemberDetails 
WHERE 
    Mem_DOB >= Cast(current_timestamp As Date) AND Mem_DOB < DATEADD(d, 30, Cast(current_timestamp As Date));

更新

SELECT 
    Mem_FirstNA, Mem_LastNA, Mem_DOB 
FROM 
    MemberDetails 
WHERE 
    DATEDIFF(DAY, GETDATE(), DATEADD(YEAR, DATEDIFF(YEAR, Mem_DOB, GETDATE()), Mem_DOB)) BETWEEN 0 AND 30

尝试这个 

        SELECT 
           Mem_FirstNA, Mem_LastNA, Mem_DOB
        FROM 
             MemberDetails 
       WHERE DAYOFYEAR(Mem_DOB)-DAYOFYEAR(getdate())<=30

应该管用。根据评论删除了使用之间。也适用于 1 月的出生日期

DECLARE @now DATETIME
    SET @now = GETDATE()

 SELECT Mem_FirstNA, Mem_LastNA, Mem_DOB
   FROM MemberDetails
  WHERE 
   CASE WHEN month(Mem_DOB) = 1
   THEN DATEADD(YY, YEAR(DATEADD(DAY, 30, DATEADD(m,  month(@now) - 1, DAY(@now) - 1))) - 1900, DATEADD(m,  month(Mem_DOB) - 1, DAY(Mem_DOB) - 1))
   ELSE DATEADD(m,  month(Mem_DOB) - 1, DAY(Mem_DOB) - 1)
    END
      > DATEADD(m,  month(@now) - 1, DAY(@now) - 1) 
    AND 
   CASE WHEN month(Mem_DOB) = 1
   THEN DATEADD(YY, YEAR(DATEADD(DAY, 30, DATEADD(m,  month(@now) - 1, DAY(@now) - 1))) - 1900, DATEADD(m,  month(Mem_DOB) - 1, DAY(Mem_DOB) - 1))
   ELSE DATEADD(m,  month(Mem_DOB) - 1, DAY(Mem_DOB) - 1)
    END
      < DATEADD(DAY, 30, DATEADD(m,  month(@now) - 1, DAY(@now) - 1))

希望能帮助到你

尝试这个

SELECT 
    Mem_FirstNA, Mem_LastNA, Mem_DOB 
FROM 
    MemberDetails 
WHERE 
    WHERE DATEPART(mm,Mem_DOB) BETWEEN DATEPART(mm,getDate()) AND DATEPART(mm,getDate())+1;

为什么不使用这个 where 子句：

WHERE MEM_DOB BETWEEN GETDATE()-1 AND GETDATE()+30

尝试这个... SELECT Mem_FirstNA, Mem_LastNA, Mem_DOB FROM MemberDetails WHERE ltrim(str(year(GETDATE()))) + '-' + ltrim(str(month(Mem_DOB))) + '-' + ltrim(str(day(Mem_DOB)) ) >= getdate() - 1 AND ltrim(str(year(GETDATE()))) + '-' + ltrim(str(month(Mem_DOB))) + '-' + ltrim(str(day(Mem_DOB)) ) <= getdate() + 30

编辑：这个答案的评论正确地指出，如果今年是闰年，它将不起作用。所以这次更新。使用函数获取两个日期之间的日期列表可以更有效地生成日期列表

Select Mem_FirstNA, Mem_LastNA, Mem_DOB from MemberDetails m, (
Select datepart(dd,getdate()) as d,  datepart(mm,getdate()) as m
union
Select datepart(dd,getdate() + 1) as d,  datepart(mm,getdate() + 1) as m
union
Select datepart(dd,getdate() + 2) as d,  datepart(mm,getdate() + 2) as m
union
Select datepart(dd,getdate() + 3) as d,  datepart(mm,getdate() + 3) as m
union
Select datepart(dd,getdate() + 4) as d,  datepart(mm,getdate() + 4) as m
union
Select datepart(dd,getdate() + 5) as d,  datepart(mm,getdate() + 5) as m
union
Select datepart(dd,getdate() + 6) as d,  datepart(mm,getdate() + 6) as m
union
Select datepart(dd,getdate() + 7) as d,  datepart(mm,getdate() + 7) as m
union
Select datepart(dd,getdate() + 8) as d,  datepart(mm,getdate() + 8) as m
union
Select datepart(dd,getdate() + 9) as d,  datepart(mm,getdate() + 9) as m
union
Select datepart(dd,getdate() + 10) as d,  datepart(mm,getdate() + 10) as m
union
Select datepart(dd,getdate() + 11) as d,  datepart(mm,getdate() + 11) as m
union
Select datepart(dd,getdate() + 12) as d,  datepart(mm,getdate() + 12) as m
union
Select datepart(dd,getdate() + 13) as d,  datepart(mm,getdate() + 13) as m
union
Select datepart(dd,getdate() + 14) as d,  datepart(mm,getdate() + 14) as m
union
Select datepart(dd,getdate() + 15) as d,  datepart(mm,getdate() + 15) as m
)X
where   
datepart(dd, m.Mem_DOB) = x.d and datepart(mm, m.Mem_DOB) = x.m
