Question

查询：

wait_time

这就是我想要的，但我收到转换错误

我告诉你wait_time = CONVERT(VARCHAR, DATEDIFF(Hour, time_created, time_responded) % 24) + '.' + CONVERT(VARCHAR, DATEDIFF(minute, time_created, time_responded) % 60)是

19.07

输出为：UPDATE dbo.FinalExtract SET WEWE = CASE WHEN Wait_time <= '24' THEN CONVERT(varchar, dateadd(hour, -24, Wait_time)) ELSE CONVERT(varchar, dateadd(hour, +24, Wait_time)) END

如果输出值小于24小时，我想增加+24小时，如果输出值超过24小时，则需要额外增加24小时。

我试过这个

docker inspectimage imagename

但它无效我收到转换错误。

Answer 1

时间部分应该有冒号。你的wait_time应该是

wait_time = CONVERT(VARCHAR, DATEDIFF(Hour, time_created, time_responded) % 24) + ':'
        + CONVERT(VARCHAR, DATEDIFF(minute, time_created, time_responded) % 60)

Answer 2

我认为这会对你有所帮助：

Declare @timeCreated datetime='2016-06-09 12:26:12.000'
Declare @timeresponded datetime='2016-06-09 14:28:12.000'
declare @waittime datetime;
set @waittime=(select case when DateDiff(hh,@timeCreated,@timeresponded)   <   24 then DateDiff(hh,@timeCreated,@timeresponded) + 24else DateDiff(hh,@timeCreated,@timeresponded) end)
update dbo.finalextract set wewe=@waittime

转换日期时转换失败
