Delete Trigger

Question

Hi,
I got a question using triggers. I have a statement level delete trigger that calls a package function used to insert data into various archiving tables. In order to keep track of the deleted rows I have a row level delete trigger that keeps the deleted Ids of my objects in a special table that I later query in my statement level trigger.
My main problem is that while all triggers are called properly and data is removed from desired tables, the data that should be inserted into my archiving tables does not appear until the trigger is fired again it appears. I don't really see what could cause data to be deleted and effectively removed while the data i want to insert does not appear until the next time the trigger is fired.
could it be that i need to explicitely commit the inserted data ?
If it's not clear, I could always post some of the code used.
Thanks,
Greg

Answer 1

Sure (I hope it won't be too messy though).
---- PACKAGE DEF.
I have a package variable defined as follows:
TYPE idTable IS TABLE OF NUMBER(19) INDEX BY BINARY_INTEGER;
And my variables:
del_oldRows idTable;
del_emptyRows idTable;
---- PACKAGE BODY
In the body I have calls like this:
PROCEDURE delete_transaction(aID NUMBER) IS
BEGIN
-- I) Add New Data into appropriate archiving tables
-- 1) Many-to-Many Table for first object
INSERT ALL INTO X_OBJ1_OBJ2_DLTD
DLTD_ID,
OBJ1_ID,
OBJ2_ID
SELECT
ID,
OBJ1_ID,
OBJ2_ID
FROM X_OBJ1_OBJ2
WHERE (X_OBJ1_OBJ2.ID = aID )
-- 2) Second object <SNIP>
-- 1) Many-to-Many Table for first object
DELETE FROM X_OBJ1_OBJ2
WHERE (X_OBJ1_OBJ2.ID = aID );
END delete_transaction;
---- Before Delete Trigger (Statement Level)
This one resets the package in a consistent state:
BEGIN
mypackage.del_oldRows := mypackage.del_gatetrans_emptyRows;
END;
---- After Delete Trigger (Row Level)
This one adds Ids in my package variable:
BEGIN
mypackage.del_oldRows(mypackage.del_oldRows.COUNT + 1) := :OLD.ID;
END;
---- After Delete Trigger (Statement)
This one goes through each row in my package "table" and calls the function to add the related data in my archiving table:
BEGIN
FOR i IN 1 .. mypackage.del_oldRows.COUNT LOOP
mypackage.delete_transaction(mypackage.del_oldRows(i));
END LOOP;
mypackage.del_oldRows := mypackage.del_emptyRows;
END;
---- END
Anyways that's the basic logic. Kinda what is suggested for mutating tables when playing with UPDATE triggers I guess. Here it's just because I want my triggers to be simple and focus on inserting the archiving data for the object triggering the... trigger while related objects that need to be archived should be taken care of in my package function. My problem is that the data is removed properly but not appears as inserted until the next time the trigger is fired, as if i was always "one" trigger late :(.
If it's not clear enough, please let me know.
Thanks,
Greg
