Question

Few of questions for bulk-bind and trigger (Oracle 10g)

1) Will row level trigger execute in case of bulk binding ?
2) If yes then, is there any option to surpress the execution only for bulk binding ?
3) If no then, is there a way to execute row level trigger in bulk binding ?
4) Will performance hamper in case row level trigger executes for bulk binding ?

Answer 1

Triggers are still enabled and fired when bulk-bind inserts are performed. There is nothing intinsic you can do to stop that, but of course you can put your own logic in the trigger and the code that does the bulk insert like as follows…

In a package specification:

create or replace package my_packags is

    in_bulk_mode boolean default false;

    ... -- rest of package spec
end;

In the trigger:

begin
    if NOT my_package.in_bulk_mode then
        -- do the trigger stuff
    end if;
end;

In the calling code:

my_package.in_bulk_mode := true;
-- do the bulk insert
my_package.in_bulk_mode := false;
