First day of the next month

问题

I'm trying get the results where it only displays OrderDates before the LAST day of the CURRENT month. I'm guessing it would be like this...

SELECT OrderDate
FROM Orders
WHERE OrderDate < (code for first day of the next month?)

回答1:

First day of next month:

sql-server 2012+

DATEADD(d, 1, EOMONTH(current_timestamp))

sql-server 2008 and older:

DATEADD(m, DATEDIFF(m, -1, current_timestamp), 0)

回答2:

Your question is somewhat ambiguous, but this will give you '(code for the first day of the month)'

SELECT OrderDate
FROM Orders 
WHERE ORDERDATE < DATEADD(month, DATEDIFF(month, 0, GETDATE()), 0)

回答3:

SELECT DATEADD(month, DATEDIFF(month, 0, getdate())+1, 0) AS StartOfMonth

回答4:

Try this

SELECT OrderDate
FROM Orders 
WHERE ORDERDATE < DATEADD(dd,-(DAY(DATEADD(mm,1,getdate()))-1),DATEADD(mm,1,getdate()))

Take a look at here

回答5:

SELECT OrderDate FROM Orders WHERE orderdate < (LAST_DAY(CURRENT DATE) + 1)

回答6:

    Select Convert(date,Dateadd(dd,1 - DATEPART(dd,getdate()), DATEADD(mm,1,getdate())),103)
