I would like to know mainly if there is any possibility to come out of the complete execution of pl/sql program inside a trigger. It shouldn't be like any raise_application_error() or exception. It should be like return statement in a normal pl/sql program. So please help me how could I exit in a trigger manually in between a code.

What I have tried:

I tried using raise_application_error(),but in this it terminates abnormally but what i want is an insert statement should not be executed if condition is false in a before insert trigger. I tried exception but it executes insert statement which is present in another program on which trigger must be executed.

Write a trigger like this:

SQL

create or replace 
trigger <triggername>
before update on <tablename>
for each row
declare
    isexception number := 0;
begin
    begin
        <sql statements that may cause exception>
    exception
        when others then 
            isexception := 1;
    end;
/* the exception is handled in the NESTED begin-exception-end block
and you can exit normally
*/
end;

An example of a procedure where execution continues after DIVISION BY ZERO since exception is handled in inner block

create or replace
procedure testexcept
as
i number := 0;
five constant number := 5;
begin
	for i in 1 .. 10 
	loop
		begin
			dbms_output.put_line('5 / (' || i || ' - 5)  ' || five / (i - five));
		exception
			when others then
				dbms_output.put_line('inner exeption -  divide by zero error!!');
		end;
	end loop;
end testexcept
;
