I have just been given an assignment for University on databases where I have to use Oracle APEX. For one of my columns in a report, I need to use a format mask. The format mask I need in the form of AAAA00, where A is any letter and 0 is any number.
Trying to get this to work is an issue though. I've heard the syntax for any number is 9 and I assume it's A for the letter, so wouldn't the format mask be AAAA99?
I tried using it but didn't succeed. When using the form, you can still input anything. I even tried using one of the default date options for the format mask, and that didn't work either.
Any ideas on what to do?
Oracle APEX Format Mask is only for the Number and Date type objects, you can't format strings using it.
Also, Format Masks are for display only, lets say I have a mask 9G9G9G9 in an Interactive Grid column, it would display numbers like : 3,1,4,1. I could go and edit my cell putting 1337, it won't change until I save my report, it will then format itself in my mask and display my number as 1,3,3,7.
I believe you are trying to restrict your user from giving an input other than in your format, (an input mask), I believe this post could help you achieve what you are trying .
