不知各位项目中会不会保存个人信息的星座属性，我这是项目中遇到了，把代码贴出来供需要的人吧，
SQL Server 函数创建语句：
CREATE FUNCTION [dbo].[f_星座]
(
@birthdate datetime
)
returns nvarchar(6)
AS
begin
declare @month int, @day int, @result nvarchar(6)
set @month = DATEPART(MONTH, @birthdate)
set @day = DATEPART(DAY, @birthdate)
if ((@month = 1 and @day >= 20) or (@month = 2 and @day <= 18))
begin
set @result = '水瓶座';
end
else if ((@month = 2 and @day >= 19) or (@month = 3 and @day <= 20))
begin
set @result = '双鱼座';
end
else if ((@month = 3 and @day >= 21) or (@month = 4 and @day <= 19))
begin
set @result = '白羊座';
end
else if ((@month = 4 and @day >= 20) or (@month = 5 and @day <= 20))
begin
set @result = '金牛座';
end
else if ((@month = 5 and @day >= 21) or (@month = 6 and @day <= 21))
begin
set @result = '双子座';
end
else if ((@month = 6 and @day >= 22) or (@month = 7 and @day <= 22))
begin
set @result = '巨蟹座';
end
else if ((@month = 7 and @day >= 23) or (@month = 8 and @day <= 22))
begin
set @result = '狮子座';
end
else if ((@month = 8 and @day >= 23) or (@month = 9 and @day <= 22))
begin
set @result = '处女座';
end
else if ((@month = 9 and @day >= 23) or (@month = 10 and @day <= 23))
begin
set @result = '天秤座';
end
else if ((@month = 10 and @day >= 24) or (@month = 11 and @day <= 22))
begin
set @result = '天蝎座';
end
else if ((@month = 11 and @day >= 23) or (@month = 12 and @day <= 21))
begin
set @result = '射手座';
end
else if ((@month = 12 and @day >= 22) or (@month = 1 and @day <= 19))
begin
set @result = '摩羯座';
end
return @result
end
