Operator is not valid for type 'Date' and type 'Date'

I was wondering if someone could assist me in writing an experession that
would subtract 2 DateTime's. I have 2 DateTime fields and want to display
both in a report and in a third column the difference between the 2 values.
However, I get an error:
"Operator is not valid for type 'Date' and type 'Date'"
Many thanks,
SimonYou can get the difference from SQL by trying something like this in your
store proc or query
SELECT date1, date2, DATEDIFF(d, date1, date2) AS date3
hope it helps.

difference in total seconds in the report rather than the query, you can use
an expression like this:
=Datediff("s", Fields!End_Time.Value, Fields!Start_Time.Value)

the SQL solution but thanks for both. What I want to return is the
difference in days and hours but can seem to do it I changed the format
string to "d" instead of "s" to return the number of days but when I tried
to use "d h" i get "#error".
Thanks for the help.
