For a stored procedure in sql server 2008 management studio i'm trying to build the following:
SELECT MAX(Orderdatum) AS Orderdatum,
klantnummer
FROM Klantenkaart
GROUP BY klantnummer
this gives me the MAX
orderdatum but this i want to combine with : orderdatum < DATEADD(YEAR, -2, SYSDATETIME())
So I want the selection of the records where max(orderdatum) = 2 years ago.
How can I do this?
Try this, Use having
with group by
select MAX(Orderdatum)As Orderdatum, klantnummer from Klantenkaart
group by klantnummer
having orderdatum < DATEADD(YEAR, -2, SYSDATETIME())
Check this :
SELECT
MAX(Orderdatum) AS Orderdatum,
klantnummer
FROM Klantenkaart
WHERE orderdatum > DATEADD(year,-2,GETDATE())
GROUP BY klantnummer
Just put your condition as a WHERE clause;
SELECT MAX(Orderdatum)As Orderdatum, klantnummer
FROM Klantenkaart
WHERE orderdatum < DATEADD(YEAR, -2, SYSDATETIME())
GROUP BY klantnummer
