The aim of this exercise is to create a function to show the success rate for each film (the number of Oscars it won, divided by the number it was nominated for):
A film clearly can't win more Oscars than it is nominated for, so the first row looks like an anomaly in the database!
To do this, create a function called OscarHitRate which takes two arguments:
|Argument||What it will hold|
|1||The number of Oscars won|
|2||The number of Oscar nominations|
Your function should return the percentage success rate (this will be a decimal number, which you'll then format in the query to look like a percentage).
Your function should return 0 if a film didn't get any nominations, to avoid any divide by zero error.
Test your function in the immediate window, then use it to create the query shown at the start of this exercise.
Save any open queries and modules, then close them down.
