【问题描述】：

我目前选择LAST年当前月份的数据。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，我不想返回 7 月 1 日至 31 日，而是希望返回 2014 年 7 月 2 日至 2014 年 8 月 1 日（含）。因此，在当月有效地 +1 天。这可能吗？

是的，只需将计算结果加 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)
