Hi, nice to meet you all ^^
I've been given this access database to look at which could eventually be upgraded to SQL, I am conducting a kind of initital research in to how we would go about it. The previous system has developed over time and is pretty messy. I'm not really a database developer, but as everyone is busy on other things, this side project has been given to me to look at as a warm up!
Basically I've managed to upsize all the tables and their contents, and have begun copying the forms over to a .adp - creating most of the queries as stored procedures.
I'm working through cronologically, and this is the 2nd query the system requires... It was full of IIf statements which I have commented out. The adp works, but is missing a lot of data - can't really work out where it was meant to be feeding from, I personally can't stand access - but it's what the original was created in and what they want to use.

I've commented out the IIf statements. I began by trying to convert them in to CASE statements and such - but frankly can't get my head around that.
Getting back to basics... I suppose the question would be: I am upsizing from access to SQL, what the heck do I do with all these IIf statements?
