Question

I have two columns. ColA and ColB contains char(10) with data “20090520” and “20090521”.

I want to select and get the date difference in days. I have tried using Format() and CDate()
but MS Access always display as #ERROR.

Answer 1

Access prefers its dates in this format:

#2009-12-01#

You can convert your date to something Access understands with:

CDate(Format([ColA], "0000-00-00"))

Or alternatively:

DateSerial(Left([ColA],4),Mid([ColA],5,2),Right([ColA],2))

And to display the result in your preferred format:

Format(<date here>, "dd-mm-yyyy")
