When executing the steps in this query. I am running into an issue with the

DECLARE @CutoffDate DATE = DATEADD(YEAR, @NumberOfYears, @StartDate);

I get a message of Msg 137, Level 15, State 2, Line 2 Must declare the scalar variable “”CutOffDate”.

Should I be adding something in this syntax? Meaning “year” should be defined? or something along those lines?

Answer 1

Provided that you have defined the @StartDate and @NumberOfYears this works just fine.

DECLARE @NumberOfYears INT = 1 ,
    @StartDate DATETIME = '2016-11-01';

DECLARE @CutoffDate DATE = DATEADD(YEAR, @NumberOfYears, @StartDate);

SELECT  @CutoffDate;

Answer 2

I notice a case-sensitive difference between your declaration @CutoffDate, and @CutOffDate from the error message.

Check to see if you're not using a case-sensitive collation.
