date difference (1 Viewer)

[bretch]

Hi,
I have here a situation wherein i have two date fields a "start date" and an "end date". I would like to have a third field in the same table that would automatically store the date difference of the two fields in minutes...
How will this be done? Any help is highly appreciated....
thanks

There is no need to store the difference when you can calculate it so easily in a query or on a form or report. Just use DateDiff().

thanks Pat,

it worked on forms and reports.
Just curious about it, is it possible to store the difference in a third field? how

As a general rule NEVER store calculated values.....

Of course it's possible. You can update the calculated field's value in the BeforeUpdate event of a form or your can run an update query. Neither method is recommended.
