Syltrem,

There is absolutely nothing wrong with using DBMS_OUTPUT in production code. It has its own limitations but if it still does what you need - just use it. The output is not transactional and it's usefull in the situations like yours. You can have output messages even if your pl/sql block rolled back a transaction.

There are horses for courses. For the situations like Syltrem's your approach is an overkill. DBMS_OUTPUT works fine there with the additional advantage of non-transactional output.

Ever heard about output redirection and logfiles?
