consider..but never code

I came across this interesting piece of code while I was actually looking for searching for something else.

Create or replace procedure <>...
begin
 merge into...
 using...
 
 -- more merge statements ..followed by all condition checks

EXCEPTION
   WHEN NO_DATA_FOUND THEN
   NULL;
   WHEN OTHERS THEN
 -- CONSIDER LOGGING THE ERROR AND THEN RE-RAISE
 --      RAISE;
   NULL;
END <>;
