Re: trigger question

What is the purpos of this code?

It looks like you trying to simulate a delete cascade. You would better use an appropiate constraint definition. If that's not the purpose and your rowcount is the total number of rows in that table you could perform a
select count(*) into <any *package*> variable from table
and decrement the package variable before row, and refer to the package variable in the rest of your code.
This strategy looks cumbersome too, as the delete shouldn't do anything is the relationship has been correctly maintained.
