在SQL（WinSQL）中過濾出將來的日期

Question

我在WinSQL中有這樣的查詢：

select CALENDAR as CALENDAR,
       HD_FLAG as HD_FLAG,
       counts as COUNTS,
       CAP_location as AREA,
where CALENDAR >= 20150101
group by 1,2,3,4

但是，有些將來的數據值我要過濾掉。 我可以添加一個函數或另一個where子句來過濾掉今天之后的日期嗎？

Answer 1

使用WINSQL now()函數，以便：

 select CALENDAR as CALENDAR,
 HD_FLAG as HD_FLAG,
 counts as COUNTS,
 CAP_location as AREA,
 where CALENDAR >= now()
 group by 1,2,3,4
