Using MS Access/MS Access


I'm trying to calculate length of employment in days from an employee table. Some employees are still working so I'm not sure how to write the condition for this using a query.I have an EndDate column & a StartDate column.I also created a column Now(). I would really appreciate if you can please help me.

Hi Reenu,

Let's assume you have 3 fields

[Start Date]
[End Date]
[Employment Days]

Where [Employment Days] = [Start Date]until today's date.

You need to use a DateDiff() function.
Please check this link for the entire usage:

YouTube Video:

DateDiff(interval, date1, date2 [, firstdayofweek] [, firstweekofyear] )

In your case
DateDiff(interval, [Start Date], Now() [, firstdayofweek] [, firstweekofyear] )

The above should be the code on the AfterUpdate event of the [Start Date] field. So no matter however long any employee has worked or is still working you will get the exact count of employment days until date.

Hope this will help
