I see these points as a big difference between low-level pl/sql fragments around database and coding big domain components. Raise_application_error Vs Raise If you recompile the subprogram with a CREATE OR REPLACE statement, the current settings for that session are used. for logging the error, it would be: when others then log_it(); raise; end; (and I think logging is a function of the uppermost level -- the client optimally, they have the The END USER is free to hit the submit button over and over again, but the transaction will keep failing until someone fixes it.

You can have any number of exception handlers, and each handler can associate a list of exceptions with a sequence of statements. How can i do that (using a trigger ? ) Thanks in advance for your time . Oracle Raise
When we have a large program, we capture the location and state into specific variables which we output using WHEN OTHERS (RAISE_APPLICATION_ERROR).

The call to RAISE_APPLICATION_ERROR takes a user-defined error number and a text string. I know DMT is sick and max_extents should be taken care of but in a situation where there are lots and lots of inserts than usual, is the application responsible to Tips for Handling PL/SQL Errors In this section, you learn techniques that increase flexibility. But remember, an exception is an error condition, not a data item.
The optional OTHERS exception handler, which is always the last handler in a block or subprogram, acts as the handler for all exceptions not named specifically. Best strategy to open a box with three digit codes? DECLARE logical_error EXCEPTION; BEGIN RAISE logical_error; EXCEPTION WHEN logical_error THEN ...
