I am trying to create a function within my select statement that will return the fiscal month number. My company's fiscal calendar starts on October 1. The first problem I had is I wasn't sure if there was any easy way to just say if the current month is X return Y. Instead, I had to use the full date, because the function I knew of would just say "When date is between A and B..." The problem there is I will have to update it every so often with new years, and removing past years so as to avoid the query getting too large. Is there any way to instead just use the month? Then, I could just say "If current month is X return Y," and it wouldn't matter the year. Either way, below is what I used. When I try to preview it in Visual Studio 2008, I am getting an error saying "The conversion of a varchar data type to a datetime data type resulted in an out-of-range value."
I've seen some questions here regarding fiscal calendars in the past, but I've never understood the answers people have given. I have found that a little confusing, so I was hoping this simpler (even if not necessarily ideal) solution I found would help. Unfortunately, I am getting an error, so obviously it did not. Does anybody have any advice they can offer to get this to work?
