Question

  convert(datetime,  BIRTH_MM + '/' +  BIRTH_DD + '/' + BIRTH_YY, 103) as Birthdate

因此，连接字符串如下所示：04/05/88

试图让这个工作。

尝试了这个，关闭我现在得到一个约会，但它给了我1900年或1905年不正确

convert(datetime,  BIRTH_MM + BIRTH_DD + BIRTH_YY, 103) as Birthdate

更新

尝试了一些东西，但还没有完成：

 case when(BIRTH_DD > 0 and BIRTH_MM > 0 and BIRTH_YY > 0)
    then 
            convert(datetime, cast(BIRTH_DD as varchar(1)) + '/' + cast(_BIRTH_MM as varchar(2)) + '/' + cast(BIRTH_YY as varchar(4)), 103)
    else
            convert(datetime, '1900-01-01', 103) as Birthdate,
        end

Answer 1

如果没有在这些值上看到您的表结构或数据类型，您可以使用与此类似的内容：

declare @BIRTH_MM int = 04
declare @BIRTH_DD int = 05
declare @BIRTH_YY int = 1988

select convert(datetime,
               cast(@BIRTH_MM as varchar(2)) + '/' +  
               cast(@BIRTH_DD as varchar(2)) + '/' + 
               cast(@BIRTH_YY as varchar(4)), 101) as Birthdate
