我有一个 TIME
类型的变量,我需要将这个变量的时间除以 2.
I have a variable of type TIME
, I need to divide the time of this variable by 2.
我的 SQL 代码:
DECLARE @TEMPO AS TIME = '01:31:00'
SELECT (@TEMPO / 2 ) AS RESULT
--the result should be: 00:45:30
SQL Server 但是抛出一个错误:
SQL Server however throws an error:
操作数类型冲突:time 与 int 不兼容
Operand type clash: time is incompatible with int
欢迎任何帮助!
另一种选择是将时间转换为 datetime
再转换为 float
,然后除以二.
Just another option is to convert the time to datetime
and then to float
, and then divide by two.
示例
DECLARE @TEMPO AS TIME = '01:31:00'
Select convert(time,convert(datetime,convert(float,convert(datetime,@Tempo))/2))
退货
00:45:30.0000000
