Thanks, Phil just assign the varchar2 to a number and catch any exceptions. Shurley it should be a "when invalid number" and or when numeric or value error that should be used, or you could get any other error and wrongly assume that its because it is not a number ;) February 02, 2004 - am UTC I said it almost certainly is a bug -- not 100%, almost certainly :) Here -- we are in FACT expecting an exception to be raised AND we can deal with it MEANING it isn't an error but an expected "condition" -- like NO_DATA_FOUND.
There are two exceptions that could be raised -- hence the use of when others here -- since the ONLY thing that could be going wrong here is in fact "invalid number". (My typing is not better, btw) But, on a more serious note, who is to say that "..that should run when it is in fact NOT a number..." does not include a RAISE? I recall in another forum a discussion about creating a function to determine if a value is a number, and in the end, we decided, only the customer/coder can determine what a number is It came down to creating test data (and a fat finger), to discover that not all numbers look like numbers.
However it does not capture the invalidity if Email String were to be say [email protected] You may use the below pl/sql function for Email Address Validation.

If you do not want to use the Message Template property to hard-code a message template (perhaps for internationalization), you can use a template stored in the application resources.
You must also specify a Message Template Resource Type Name value.
