SQL View Syntax

I have this Access query and want to make it into a view, can anyone help with syntax?
SELECT IIf([Date_Last_Service] Is Null,[Service_Due_Date],IIf([Service_Due_Date] Is Null,[Date_Introduced],[Date_Last_Service])) AS LastService, DateDiff("m",[LastService],Date()) AS ServiceDue
FROM tbl_Jig_Register;

the sql looks incorrect, I think you reversed some parameters

I will try to "auto-correct" them :
select coalesce( Date_Last_Service, Service_Due_Date, Date_Last_Service, Date_Introduced) LastService
, DateDiff( month, coalesce( Date_Last_Service, Service_Due_Date, Date_Last_Service, Date_Introduced) , getdate()) ServiceDue
FROM tbl_Jig_Register;

Looks like Guy has answered your question, so I'll add a token two cents
A lot of that is covered in this article:   Migrating your Access Queries to SQL Server.
Let me know if there's anything you come across that's not in the article, and I'll add it.
