Monthly data based on dates

Hello,

I am new to Access and trying to get an employee database. Now, I like to
have a query/report (that I can afterwards download to excel) that tells me
if a person was in the company during a certain month or not - based on the
start date and end date. The end date can be empty.

What I am doing now is to have a query for each month that tells me if the
person was in the company or not, with the following calculation:
Jan 09: IIf([Employee]![Start Date]=31/1/2009 And ([Employee]![End
Date]=31/1/2009 Or [Employee]![End Date]=""),1,0)

However this doesn't give the desired result. Any suggestion?

Thanks.

Try this -- Use Nz function to replace a NULL date in your table with
today's date (or you can use any other date you wish), and change your date
format to the US version (which is how ACCESS will interpret dates in a
x/x/yyyy format), and delimit the dates with # characters:

Jan 09: IIf([Employee]![Start Date]=#1/31/2009# And Nz([Employee]![End
Date], Date())=#1/31/2009#,1,0)

Great - this works fine.

Thanks a lot.
