sql working days holidays

Question

I\'ve seen different version of this kind of function for other coding languages (Python, jQuery, etc.) but not for SQL. I have a procedure that needs to have a date calcul

Answer 1

Assuming we have a DateTable with columns actual_date (date) and is_holiday (bit) , containing all dates and where all workdays have is_holiday=0:

SELECT actual_date from 
(
    SELECT actual_date, ROW_NUMBER() OVER(ORDER BY actual_date) AS Row 
    FROM DateTable
    WHERE is_holiday= 0 and actual_date > '2013-12-01'
) X
WHERE row = 65

This will find 2013-12-01 plus 65 workdays, skipping holidays.
