SQL - 여러 범주를 몇 가지 범주로 그룹화하십시오.

쿼리가 있습니다. 하나의 열이 상태 열이고 하나의 열이 경과 시간 열인 행을 반환합니다. ~ 8 개의 상태 카테고리가 있습니다. 특정 상태와 경과 시간을 ~ 3 범주로 합치기를 원합니다. 누구든지 내가 어떻게 할 수 있을지 생각해?SQL - 여러 범주를 몇 가지 범주로 그룹화하십시오.

여기는 항목을 일 단위로 저장소로 분할하는 현재 쿼리입니다. 예를 들어, 그래서, "유휴", "실행"및 "폐기물"

내가 3 개 종류로 특정 범주에 대한 경과 시간을 결합하려는 : 여기

declare @STARDTZ as datetime2 
declare @LASTDTZ as datetime2 

declare @STARTDT as datetime2 
declare @LASTDT as datetime2 

set @LASTDT = getdate() 
set @STARTDT = DATEADD(dd,-7,getdate())

) as t 

join dates d on d.dt >= cast(t.StartDT as date) and d.dt<=cast(t.LastDT as date) 

group by DateBin, StartDT, Name, dt, LastDT, FullName

는 반환 것입니다 , "run_parts"및 "run_test"는 "실행 중"으로 요약됩니다.

의미가 있습니까? 어떻게 접근 할 수 있습니까? 감사!

당신은 당신이 파생 테이블에서 원하는 버킷에 이름을 정렬 할 case 표현을 사용할 수 있습니다

with dates(dt) as (select @stardtz union all select dateadd(day,1,dt) from dates where dt < @lastdtz)

    ,case when datediff(day,Lastdt,dt)=0 then t.Lastdt else dateadd(day,1,d.dt) end)/60000.0 as IntervalMin

을하거나 select 및 group bycase 표현 대신 t.Name 할 수 있습니다
