    You could do something like this:

    IFNULL(@Year, DATEPART(year, Date)) = DATEPART(year, Date)

    IFNULL returns its first non-null argument. In this case, the query will compare @Year to DATEPART(year, Date) as long as @Year is not null. If it IS null, then it’ll compare DATEPART(year, Date) to DATEPART(year, Date), which will always be true.

    Edit: Note that DATEPART is not a native SQLite method (the OP referenced it so it may be a custom thing he/she is using). A native solution is to use strftime("%Y", Date) (Thanks @Jason!)
