How can I expand a table row for each day within a range using VB.net 2012 and/or SQL?

This is probably a very basic issue, but I'm a noobie. I don't really know how much detail to give but here we go.

I want to take  Table A  and create Table B to show one row for each date within the Checkin/CheckOut date range in Table A.

Table A
CheckIn              CheckOut      Name
8/1/2014      8/5/2014      Watson, JB


Table B
CheckIn              CheckOut      Name               DateValue
8/1/2014      8/5/2014      Watson, JB        8/1/2014
8/1/2014      8/5/2014      Watson, JB        8/2/2014
8/1/2014      8/5/2014      Watson, JB        8/3/2014
8/1/2014      8/5/2014      Watson, JB       8/4/2014
8/1/2014      8/5/2014      Watson, JB        8/5/2014

Are you building a report?

If so you could create a formula to do that.

Local StringVar strOut;
Local DateVar DateIndex;

For DateIndex := {Checkin} to {CheckOut} do
    strOut := strOut + CStr({CheckIN}) + "   " + CStr({CheckOut}) + "   "  + {Name} + "   " + CStr(DateIndex) + chr(13);

strOut

Create a CALENDAR table with one row for each date.  Join to that table with a condition of:
CALENDAR.Cal_Date >= B.Checkin AND CALENDAR.Cal_Date < B.Checkout.

If your connection method doesn't support this types of joins, remove the join and apply the condition to the record selection formula.

By the way, a CALENDAR table is very useful for a variety of other reporting needs. It is routinely included in data warehouse designs (where we refer to it as the DATE Dimension).
