I need 3 validations for my apex oracle database application and can't seem to find the solution.
- validation so that the field cannot be Null
- Validation so that the number entered must be between 1 and 1000
- Validation so that the date of birth cannot be after
5/6/2018
(dd // mm / yyyy
format)
These validations are used in the form using CREATE VALIDATION in the edit page
