创建财政周数
create fiscal week number
如何将以下逻辑放入格式 SQL 服务器将用于创建财政周数?
if (datepart(week,getdate())-4) <= 0 then (datepart(week,getdate())+49) else (datepart(week,getdate())-4)
CASE 语句应该有效:
CASE
WHEN (datepart(week,getdate())-4) <= 0
THEN datepart(week,getdate())+49
ELSE
datepart(week,getdate())-4
END
您可以使用 case
表达式:
SELECT CASE WHEN (DATEPART(WEEK, getdate()) - 4) <= 0
THEN DATEPART(WEEK, getdate()) + 49
ELSE DATEPART(WEEK, getdate()) - 4
END
对于SQL Server 2012+,您可以使用IIF
SELECT IIF((datepart(week, getdate())-4) <= 0, datepart(week, getdate()) + 49, datepart(week, getdate()) - 4 )
小于SQL Server 2012版本,您可以使用CASE
。
