내가 두 개의 매개 변수 BEGINDATE을 제공

Question

분에 대한 시간표를 작성하고

내가이 코드를 작성하는 방법과 같은

예를

@begindate = '2012-01-01' 
@endate = '2013-01-01' 

결과

begindate    enddate 
2012-01-01 00:00:00 2012-01-01 00:10:00 
2012-01-01 00:10:00 2012-01-01 00:20:00 
2012-01-01 00:20:00 2012-01-01 00:30:00

Answer 1

@BeginDate에서 @EndDate 사이의 10 분 간격마다 하나의 행을 생성하려는 것처럼 보입니다. 그렇다면 재귀 CTE를 사용하십시오.

DECLARE @BeginDate datetime = '2012-01-01' 
DECLARE @EndDate datetime = '2013-01-01' 

;WITH cte AS (
    SELECT @BeginDate AS BeginDate, 
      DATEADD(minute, 10, @BeginDate) AS EndDate 
    UNION ALL 
    SELECT DATEADD(minute, 10, BeginDate), 
      DATEADD(minute, 20, BeginDate) 
    FROM cte 
    WHERE BeginDate < DATEADD(minute,-10,@EndDate) 
) 

SELECT * FROM cte 
OPTION (MAXRECURSION 0)
