Question

在这段代码中，我只想要将日期和时间分开，我只想将其附加到第三个变量中，这样当我将时间变量@t强加到datetime时，我就编写了该代码对于日期，它需要垃圾值

你能为这个或任何其他简单方法提出任何解决方案吗？

DECLARE @d AS time
declare @s as date
declare @t as datetime
declare @l as datetime
declare @q as datetime
set @s=(SELECT CONVERT(VARCHAR(10),GETDATE(),111))
set @d='6:00PM'
set @t=cast(@s As datetime)
set @l=CAST(@d as datetime)
set @q=(SELECT DateAdd(D,0,cast(@s As datetime)+CAST(@t as datetime)))
print @q

Answer 1

您需要将时间转换为日期时间并将其添加到日期：

DECLARE @t AS time
DECLARE @d AS date
DECLARE @dt as datetime

SET @t = '6:00PM'
SET @d = '14 sep 2011'
SET @dt = @d+cast(@t as datetime)

select @d,@t,@dt

SQL Server在第三个变量中的日期和时间连接
