How to Set Field to Uppercase in Oracle Apex

I needed to get a field set to uppercase in Oracle APex (Application Express) so that when a user types into the field any letters entered are automatically converted to capitals.

What appeared to be a tricky task was actually very simple!

All you need to do it to enter the following code into the item element field.

onchange="this.value = this.value.toUpperCase();"

With this code, the user can type into the field in upper or lower case but as soon as they leave the field the content will be converted to capitals / upper case.
