How to access new value Statement Level Trigger

[gyanendar]

Hi All,
I want to access new value after upadate in statement level trigger.
But in my query I am getting old values.
Here is the Trigger Code:

CREATE OR REPLACE TRIGGER TEST_TRIGGER
AFTER UPDATE OF col3 on table_gyan
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
v_count NUMBER:=0;
v_temp_count NUMBER:=0;
BEGIN
SELECT Count(1) into v_count from table_gyan where col3='Y';
If v_count>0 THEN
SELECT COUNT(1) INTO v_temp_count from TRIGGER_TABLE;
if v_temp_count>0 THEN
UPDATE TRIGGER_TABLE SET ACTION='START';
COMMIT;
else
insert into TRIGGER_TABLE(ACTION) values('START');
commit;
end if;
END IF;
END;

.


Now when ever I am executing this query
update table_gyan set col3='Y'
where col1='3'
and col2='100'
Its not doing anything with TRIGGER_TABLE.


Please help me how to do it.

Are you sure any records are updated?

In the table records are getting updated but trigger is still taking Old value.

Ok,

So now you have values in the table where col3 has the value 'Y' Try to update col3 now, and see if the trigger_table is updated.

No ,its not updating trigger_table values.
If before updation table contains 'Y' than its working .

try using this code:

 
CREATE OR REPLACE TRIGGER TEST_TRIGGER
AFTER UPDATE OF col3 on table_gyan
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
v_count NUMBER:=0;
v_temp_count NUMBER:=0;
BEGIN
SELECT Count(1) into v_count from table_gyan where col3=:new.col3;
If v_count>0 THEN
SELECT COUNT(1) INTO v_temp_count from TRIGGER_TABLE;
if v_temp_count>0 THEN
UPDATE TRIGGER_TABLE SET ACTION='START';
COMMIT;
else
insert into TRIGGER_TABLE(ACTION) values('START');
commit;
end if;
END IF;
END;

As this is a statement level trigger and firest once every statement, the individual values are not available in the trigger.

But the post of amitpatel66 makes us think, make it a row level trigger and use the code amitpatel66 posted and see if the trigger_table table gets updated.

Yes this is for row level trigger.

@OP, are you looking at Row level trigger updates or statment level? Please confirm?

[gyanendar]

Yes this is for row level trigger.

Yes,
Finally I made it row level trigger and every thing worked fine.

But,if 100 rows of table get updated than ,tigger will get fired for all the 100 rows and does the same work.To avoid this problem ,I was thinking for statement level trigger.

Guy's can we have statement level trigger for this work.

So, the same code works for row level statement, but doesn't work for the statement level trigger?

No you cannot. If you want it to work for all the records then you should have row level trigger
