Also, a GOTO statement cannot branch from an exception handler into the current block. You can also perform a sequence of DML operations where some might fail, and process the exceptions only after the entire operation is complete, as described in "Handling FORALL Exceptions with Using the Exception Inheritance Hierarchy In the exception hierarchy shown in Figure 4, you can see that ArgumentNullException inherits from ArgumentException, which inherits from SystemException, which inherits from Exception.

The Base Case—No Error Handling at All What happens if your code includes no exception handling at all?

For a list of properties and methods inherited by Error instances, see Error.prototype.
