Trying to add an arbitrary amount of 'time' to a datetime value which starts out containing ONLY a date is fraught with problems. Try adding the last millisecond or two, for example. The way that is ALWAYS safe is to use >= @YourStartDate and <= DATEADD(DAY, 1, @YourEndDate) as your range.

Ah, be careful now. In most cases, you only want LESS THAN for the end date +1. You also have to make sure that @YourEndDate contains only a midnight time component unless its the DATE datatype.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
