You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Open the module that you have created called modFunctions.
In this module, create a function called YearsSinceRelease which shows the years since a film was released, using the field FilmReleaseDate in the table tblFilm. There are some notes on how to do this below!
Incorporate this function into a query so that you are displaying films in release date order, with the oldest film first:
A sample of the final query - King Kong was released 75 years ago and is the oldest film
To calculate the release date, you need to take the difference between the FilmReleaseDate and today's date. Here are two functions which may help you:
- Date() - returns today's date
- DateDiff("yyyy",EarlierDate,LaterDate) - returns the difference in years between two dates
Note also that you need to surround dates with hashes to test them in the immediate window:
Without the hashes, Access would not recognise 1/1/1990 as a date
When you are happy that your function works, save and close the module.
