시도했지만 실패했습니다.

update Info_Game set IG_StartTime = replace(convert(char(10), IG_StartTime, 20), '2017-11-22', convert(char(10), getdate()+1, 20)) 
update Info_Game set IG_StartTime = replace(convert(char(10), IG_StartTime, 20), '2017-11-23', convert(char(10), getdate()+2, 20)) 
update Info_Game set IG_StartTime = replace(convert(char(10), IG_StartTime, 20), '2017-11-24', convert(char(10), getdate()+3, 20))

시도해보십시오.

update Info_Game set IG_StartTime = DATEADD(day,1,DATEADD(hour,DATEPART(hour,IG_StartTime),cast(getdate() as date))) where cast(IG_StartTime as date) = '2017-11-22' 

update Info_Game set IG_StartTime = DATEADD(day,2,DATEADD(hour,DATEPART(hour,IG_StartTime),cast(getdate() as date))) where cast(IG_StartTime as date) = '2017-11-23' 

update Info_Game set IG_StartTime = DATEADD(day,3,DATEADD(hour,DATEPART(hour,IG_StartTime),cast(getdate() as date))) where cast(IG_StartTime as date) = '2017-11-24'
