Business Days

A user inputs a date and I need to have the program search for data matching the date inputted as well as anything 5 business days prior (minus holidays as well).

any idea how to code this?

Erm ... you might want to be a little bit more specific, like telling us which programming language you are using, if you're using a database and what sort, or did you just want a solution in anything?

I'm using Access 97.

OK ... so that's your database, but are you writing your own forms, using Access Reports, using a Visual Basic front end, doing an SQL Query...?

Give us some clues!

My Bad. I'm just using plain ol' Access 97 to do everything. Nothing extra.

Well, I guess I could use VB as a module.


You'll have to forgive me, I'm just learning Access.

In your form, where the date is input, you can use the DateAdd() internal function to find the entered date -5 days:

Code:

---

sStartDate = DateAdd("d", -5, sInputDate)

---

If you want to ensure that the sStartDate is a workday (ie, mon-fri) then you want to use the Format() function (See Format Characters):

Code:

---

SELECT CASE (Format(sStartDate, "w"))
CASE 1:
 ' this is a sunday
 sStartDate = DateAdd("d", -2, sStartDate)
CASE 7:
 ' this is a saturday
 sStartDate = DateAdd("d", -1, sStartDate)
END SELECT

---

So what we've done is changed it to the Friday if it's a saturday or sunday.

You can now safely search between your two dates.

In SQL:

... WHERE [EntryDate] BETWEEN [STARTDATE] AND [INPUTDATE]

Ok, I just learned that it is for 20 business days, not just 5. Any suggestions?
