Error when validating

Question

is it possible to put in the when-validate-item trigger a method to catch a specific error ie i am getting the FRM-50016 error when validating. This is fine and is expected but I want to display this information to the user as a message or so so do i put in the when-validate-item trigger:
if error 50016 then
end if
or something along those lines?
Thanks.

You can use an Annonymous Block in your When-Validate-Item (WVI) trigger, which will allow you to handle any Exceptions that occur within the annonymous block. Unless you need specific logic to occur as a result of the exception, typically, you would handle the exception in the On-Error trigger. For example:
/* WVI */
BEGIN
   ... Trigger logic here ...
EXCEPTION
   WHEN OTHERS THEN
       IF Error_Code = 50016 THEN
           ... Exception Specific Logic here ...
       END IF;
END;Personally, I prefer to keep this type of Exception Handling in the On-Error trigger.
Hope this helps,
