寻找有关如何最好地执行此代码的一些指导......
最后,我想将其插入到where子句中,以便根据当前日期驱动FSCL_YR_WK(即201804)。
AND A.FSCL_YR_WK = Case
WHEN GETDATE() between 2018-02-26 AND 2018-03-04 THEN 201804
WHEN GETDATE() between 2018-03-05 AND 2018-03-11 THEN 201805
WHEN GETDATE() between 2018-03-12 AND 2018-03-08 THEN 201806
ELSE '' END
丑陋但有效:
declare @d datetime
SET DATEFIRST 1--week starts on monday, default is sunday
set @d=convert(date,'2018-02-26')
select convert(char(4),datepart(year,@d))+RIGHT('0'+CAST(DATEPART( wk, @d)-5 AS VARCHAR(2)),2)
也许把它放在一个功能只是为了保持选择清楚
