  END IF;
END log_writter;

In the above cleanup proc,if any occurs in deleting from transaction,updating sellable_item,delete from sellable_item,deleting from purchase,


i should write a v_text to the file.


How could i handle inner exceptions


if i dont get any exceptions it should take default otherwise

v_text from the exception section.

hi!
not sure if i get it right, just put each DML statements inside an anonymous PL/SQL block, then catch the exceptions.
