Table Trigger and Stored Procedure Question

Question

I'm rusty with triggers/procedures and have a quick question.
If a rollback occurs within a procedure containing a raise_applciation_error called from a table insert trigger, will this prevent the insert on the table from occuring?
I want the transaction to be occur on the table even though an exception is raised within the called procedure.

Answer 1

If the trigger is an "after insert" and the procedure called by the trigger raises an error, will the row still be inserted?
SQL> create table t (n number);
Table created.
SQL> create or replace
  2  procedure p as
  3  begin
  4     raise_application_error(-20001,'Something bad happened');
  5  end;
  6  /
Procedure created.
SQL> create or replace
  2  trigger t_trig
  3  after insert
  4  on t
  5  begin
  6     p;
  7  end;
  8  /
Trigger created.
SQL> insert into t values (42);
insert into t values (42)
