我想要的确切日期上面的输入params.please帮我出来 –

为什么你把它标记为MySQL？ – cha

使用DateAdd：

SET @DATE_OF_BIRTH=DATEADD(year, [email protected], 
          DATEADD(month, [email protected], 
          DATEADD(day, [email protected], getDate())))

SET @YEARS=CONVERT(BIGINT,SUBSTRING(@INPUT,1,3)) 

SET @MONTHS=CONVERT(BIGINT,SUBSTRING(@INPUT,CHARINDEX ('M', @INPUT,1)-2,2)) 

SET @DAYS=CONVERT(BIGINT,SUBSTRING(@INPUT,CHARINDEX ('D', @INPUT,1)-2,2)) 

SET @DATE_OF_BIRTH=DATEADD(year, [email protected], 
DATEADD(month, [email protected],DATEADD(day, [email protected], getDate()))) 
SELECT Convert(nvarchar(12),@DATE_OF_BIRTH,105)

两个DATEADD s就足够了：

DECLARE @DATE_OF_BIRTH date 
    = DATEADD(year, [email protected], DATEADD(month, [email protected], GETDATE()))[email protected]
