如何检查SQL中DATES之间的日期？如果签入和签出日期在SeasonStart和SeansonEndDate之间返回1否则返回0

Question

@CheckInDate DATE TIME = '15/12/2010',  
@CheckOutDate DATETIME = '18/12/2010'  


SeasonStartDate DATETIME = '13/12/2010'
SeasonEndDate DATE TIME =' 20/12/2010'

Answer 1

CASE
 WHEN @CheckInDate BETWEEN SeasonStartDate AND SeasonEndDate
  AND @CheckOutDate BETWEEN SeasonStartDate AND SeasonEndDate
  THEN 1
 ELSE 0
END

Answer 2

如果您保证不允许时间旅行（进/出和开始/结束的顺序正确）：

CASE WHEN @CheckInDate >= SeasonStartDate and @CheckOutDate <= SeasonEndDate THEN 1 ELSE 0 END
