Question

I really don’t know how to ask this question or title it but here I go. I work in a school system and I have created a database for some psychologists to use to track their referrals. By state rules,they have 60 days from the date of their first meeting to finish the process. Weekends still count but HOLIDAYS DO NOT. I do not really know how to use the calender we have so that we have an accurate Calculation. For instance, with Holidays accounted for, if a kid was started today, he would need to have everything finished on 1/18/2013 That is 60 days from now based on our schedule. Does anyone have any idea where I should start?

Edit

Ok, so I now have a Calender table. Here is my issue. I have my column that I used to indicate which days are used in calculating my 60 days. Weekends can be used in that calculation. HOWEVER, they cannot be used in the result. If the 60th day lies on a Sunday or Saturday, then the date would need to go to the Friday before. I guess my first issue is really, how do I limit my calculation to the dates in my calender table?

Answer 1

You can check the weekday to ensure you have not chosen a weekend:

SELECT TOP 1 CalDate, WDay 
FROM (SELECT Top 60 c.CalDate,Weekday([Caldate]) AS WDay
      FROM Calendar c
      WHERE c.Holiday=False) a
WHERE WDay Not In (1,7)
ORDER BY CalDate DESC
