Hello,

I try to select the MAX date from a table who has a specific value, something like that:

SQL

SELECT regRaport.regRaport_id, regRaport.regRaport_date, regRaport.regRaport_soldinitial, regRaport.regRaport_soldfinal, IIF(regRaport.regRaport_categorie Is Null, 0, regRaport.regRaport_categorie) AS RegRaportCategorie
FROM regRaport
WHERE regRaport.regRaport_date=(select MAX(regRaport.regRaport_date) from regRaport  WHERE regRaport_categorie=5);

but the above query returns all value for MAX() date, not for a specific category.
Any suggestions?

Try this

SQL

SELECT	regRaport.regRaport_id,
	regRaport.regRaport_date,
	regRaport.regRaport_soldinitial,
	regRaport.regRaport_soldfinal,
	IIF(regRaport.regRaport_categorie Is Null, 0, regRaport.regRaport_categorie) AS RegRaportCategorie
FROM	regRaport
inner join (select regRaport.regRaport_id as ID,
				MAX(regRaport.regRaport_date) as regDate
		from	regRaport
		WHERE	regRaport_categorie = 5) reg
	on  regRaport.regRaport_id = reg.ID
	and regRaport.regRaport_date = reg.regDate
