Question

This line of code is a snippet from my select statement.

frdFreedays - DateDiff(dd,conReceiptToStock,GetDate()) As FreeDaysRemaining

Below is a snippet from my where clause

and frdFreedays - DateDiff(dd,conReceiptToStock,GetDate()) <= @intFreeDays

The question I have is how can I reference the FreeDaysRemaining column and so I can compare it to @intFreeDays

I am looking for something like this

Freedays <= @intFreeDays

In addition to Aaron’s answer, you could use a common table expression:

;with cte_FreeDaysRemaining as
    (
        select
            frdFreedays - DateDiff(dd,conReceiptToStock,GetDate()) As FreeDaysRemaining
            --, more columns
        from yourtable
    )
    select
        FreeDaysRemaining
        --, more columns
    from cte_FreeDaysRemaining
    where FreeDaysRemaining <= @intFreeDays
