Why is it good practice to place an 'others' exception handler in the outermost block of a PL/SQL program unit?
Why is it good practice to place an 'others' exception handler in the outermost block of a PL/SQL program unit?
Choice 1
This method provides a handler to which any exceptions not handled by specific exception handlers will be propagated.
Choice 2
'others' is the most inefficient exception handler and it should be placed as a last resort after all other exceptions have been handled.
Choice 3
Exception handling is a bad practice in general and should be avoided.
Choice 4
'others' exception handlers should be used sparingly because their definition provides the least possible information about the exceptions they trap.
Choice 5
If 'others' is placed before explicitly-stated exception handlers, it will catch all exceptions and over-ride the ability of the explicit handlers to execute.
