THROW_LAST( )
Remarks
Throws the exception back to the next outer CATCH block.
This macro allows you to throw a locally created exception. If you try to throw an exception that you have just caught, it will normally go out of scope and be deleted. With THROW_LAST, the exception is passed correctly to the next CATCH handler.
