Can anyone know how to take input in trigger and use those input in procedure which we call inside the trigger.
Second example,
Old - 92000

When (new-old) , then we got negative value but here positive value....how...?
Tried in Oracle 11G ,Followed your single steps were shown but no output Just getting errors all the time, Felt Like not Much Clarity on Topic with
Scenarios that has been used. So plz check once your end, Don't mind ,almost have spent around day to get answer but no use for me.

U r Just reading the statements what u have handy. Try to explain things clearly.
But what happen if the update query is not executed properly than also the message is display
After use is not possible...
Yeah, it depends on if its a BEFORE trigger of AFTER trigger.
I am getting error ...
UPDATE ACCOUNT SET AMOUNT=AMOUNT-10000
Error report -
ORA-00001: unique constraint (HR.SYS_C0011145) violated
ORA-06512: at "HR.TRIG_ACC", line 2
ORA-04088: error during execution of trigger 'HR.TRIG_ACC'
can you plz tell whats the reason for this error.
i guess u entered duplicate value
Do you have any unique constraint on amount table?

Hi, i have created a trigger for hr_hire and hr_fire. i am getting null values from parent to child. could you assist me where i wrong
create or replace trigger hr_tri before delete on hr_hire for each row
begin
insert into hr_fire(s_no,emp_id,emp_name,DOR,dept_id) values (s2.nextval,:new.emp_id,:new.emp_name,sysdate,:new.dept_id);
end;
When you have created a trigger then you should have seen inside the values because of you take old instead of new.
You will get the answer about a triggers
