SQL：选择去年的当前月份

Question

我目前选择去年从当月的数据。 这适用于

SELECT cast(CREATED as date) AS DATE, COUNT([ID]) AS BOOKINGS, SUM([TOTCOST]) AS Sales
from BOOKING
WHERE
CREATED >= DATEADD(month, datediff(month, 0, getdate())-12, 0)
AND
CREATED < DATEADD(month, datediff(month, 0, getdate())-11, 0)
GROUP BY cast(CREATED as date)
ORDER BY cast(CREATED as date)

但是，我不想将7月1日返回到7月31日，而是将2014年7月2日返回到包括2014年8月1日。 因此，当月有效+1天。 这可能吗？

Answer 1

是的，只需在计算结果中加1。

SELECT cast(CREATED as date) AS DATE, COUNT([ID]) AS BOOKINGS, SUM([TOTCOST]) AS Sales
from BOOKING
WHERE
CREATED >= (DATEADD(month, datediff(month, 0, getdate())-12, 0) + 1)
AND
CREATED < (DATEADD(month, datediff(month, 0, getdate())-11, 0) + 1)
GROUP BY cast(CREATED as date)
ORDER BY cast(CREATED as date)
