After creating trigger I am getting error .
PLS-00049 : Bad bind variable 'OLD.CHEMICAL_BALANCE'

Can any one help me to sort out this problem ..
Thanks in advance ..

Help with trigger

Dear All,
I have a trigger that works fine when the value is updated by a user but when the value is updated by another trigger it does not seem to work.
When i log in and update the value in sqlplus it works fine but when I update a value in another table which then calls a trigger which then updates that value in the main table the trigger does not fire.
This is the scenario. We have a table called payments. When we run a process it sets some values in this payment table.
When this value is set in the payments table it fires a trigger which then updates the invoice table (paid_date) based on some value in the payments table.
Now when this value in the invoices table is set by the trigger it is meant to call another trigger which should recognise this new value but this does not hapen.
however if i go in manually and update the invoice table, the trigger fires.
Any help will be appreciated.
Below is the trigger that does not seem to fire.
I have also included the trigger which sets this value
create or replace

The following demonstration is a direct response to your original question, in case you want to stick with that method of scheduling your index rebuilds through a trigger. In order to do ddl like alter index you will need to use dynamic sql like execute immediate. Since you can't rebuild the index before the insert or update has been committed, you will need to use dbms_job.submit to schedule the rebuild. In the following example, the index rebuild will be done as soon as the insert or update has been committed.

Need Urgent Help with trigger in Oracle 10g

Hello frd,
I am working on my DBMS Project in VB 6.0 that is Tollbooth management system
i have to insert one trigger for my project so i had decided to insert time trigger.
I have total 3 table UserLogin, Vehice and Vehicle_Data
the 3rd table Vehicle data contain the following fields
Vehicle_Type, Vehicle_No, Tax_Time, Source, Destination and Tax
Now i had done coding for tax when you select Vehicle Type, Source and Destination the Tax Field will automatically fillup and all the data will Saved in Oracle table but now my problem is that i want to create trigger for Tax_Time column When any new data inserted current time will stored in that column
I had create one but it gives error
create trigger time after insert on vehicle_Data
for each row
begin
insert into Vehicle_Data(Tax_Time) values(to_char(sysdate, 'HH:MI:SSAM DD_MON_YYYY'));
end;
Note: I am Using VB 6.0 and Oracle 10g Express Edition

I had create one but it gives errorWelcome to the forum and many many thanks for not posting the full error message, that is really helpful, since we're all a 100% sure what's going on now (yes, that was ironic ;) ).
Let me guess: a mutating table error?

As promised, please find thereafter the trigger code.
The problem to solve is that the trigger doesn't see the non committed modification because it is part of another transaction. So the row is seen as not modified by the trigger and this issue must be treated.
With "insert" there is nothing old to worry about. With "update", we have to take away the modified row from the result to check.

Help in trigger creation

Hi guys,
I am using oracle 10g on windows 2003 server.
I have two tables namely PEOPLE and UG_COMMAND.
There are two columns in People table- STAFF_CODE and USER_29. I want to create a trigger which should check if STAFF_CODE is null and
USER_29 is not null. On meeting this condition it should populate command column of UG_COMMAND table.
Thanks for help!!

Hi
Create or replace trigger people_trrg
after insert on people for each row
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
BEGIN
if :new.user_29 is not null then
if :new.staff_code is null then
Insert into UG_Command (command) values ('some value');
else
Insert into UG_Command (command) values ('some value');----this will kick in if the value is not null
end if;
end if;
EXCEPTION
WHEN others THEN Raise;
END;Note: If there are some other not null columns in UG_command, then the trigger will fail, you need to include all not null columns

Help in Trigger ( When-radio-changed )

Hi,
I have a form which represents a sales invoice and I have an item called (pay_type) It’s a radio group included (cash , debit, cheque, .. so on )
now for EX if the user choose ‘cash’
It supposed the trigger takes the invoice value and ( + ) it on the Treasury table (this is fixed)
And on the other hand it should (–) the invoice items quantities from the ( store_item ) table
And this is the problem I need help in, because I couldn't write the where condition to decrease the quantities from store_item table based on the ( item_code & store_code ) Which in the invoice.
i tried this code and i know that "the where condition is wrong here" but i try to show u what i need to do
begin
if :pay_type = 'cash'
then
update cash

Need help with trigger/new at pl/sql

I would appreciate any help as I am new to PL/SQL and have run out of ideas.
I am trying to write a trigger that when a user inserts a row into a table that records an ID, a clinic, and user initials, a second table is updated with that ID in the next available "slot" for that clinic.
I wrote a procedure that does execute successfully with ID, user initials, and clinic hardcoded. I cannot create a trigger using the fields from the 1st table instead of the hardcoded values that compiles without errors.
The tables in question are in another schema, but I have all priviledges on that schema.
I have tried referencing the fields from table 1 in every way I can think of:
1) :new.<field from table 1> and got:
ORA-04082: NEW or OLD references not allowed in table level triggers
2) :<field from table 1> and got
PLS-00049: bad bind variable '<field name>'
3) <field from table 1> , <table>.<field from table 1>, <schema>.<table>.<field from table> and got
5/38 PL/SQL: ORA-00904: "N106CLINIC": invalid identifier
14/44 PL/SQL: ORA-00904: "N106CLINIC": invalid identifier
and
5/38 PL/SQL: ORA-00904: "N106"."N106CLINIC": invalid identifier
14/44 PL/SQL: ORA-00904: "N106"."N106CLINIC": invalid identifier

14/44 PL/SQL: ORA-00904: "CCRN"."N106"."N106CLINIC": invalid identifier
in addition to "SQL statement ignored".
It does complain only about n106clinic, even though other fields referenced from the first table are n106id and n106init; n106clinic IS a valid field name in the n106 table...maybe this is just a compiler peculiarity.
Here is the code for the trigger. N106 is the table where the user inserts a row and RAMBCYL is the table to be updated. CCRN is the schema that owns the two tables.
create or replace trigger ccrn.aocylrand
after insert
on ccrn.n106
declare l_accno number;
begin
select rambcyl.accno into l_accno
from ccrn.rambcyl rambcyl
where rambcyl.clinic=n106clinic and
rambcyl.accno = (select min(r.accno)
from ccrn.rambcyl r
where r.id is null
and r.clinic = n106clinic);
update ccrn.rambcyl set id =n106id,
randdt = sysdate,
staff=n106init
where ccrn.rambcyl.accno = l_accno and
ccrn.rambcyl.clinic = n106clinic;

You cannot refer to the :old or :new column values in a statement level trigger, only in row-level triggers. I would suggest the following which does the update in a single statement:
create or replace trigger ccrn.aocylrand
after insert
on ccrn.n106
for each row -- specifies a row-level trigger
begin
update ccrn.rambcyl r1
     set id = :new.n106id,
         randdt = sysdate,
         staff = :new.n106init
   where clinic = :new.n106clinic
     and accno = (select min(r2.accno)
                    from ccrn.rambcyl r2
                   where r2.id is null
                     and r2.clinic = r1.clinic);
end aocylrand;

I need help! TRIGGER PROBLEM.

I have a case where I am checking for conflict do to date/times in table "MAINT".
if an ID that is changed or added in table "SCHEDULE", I need to change the corresponding id in table MAINT, if that change make the id go into conflict, meaning that the start_time and the end_time of the NEW record is in the start and end time of the :OLD record, then I set the conlict flag in the MAINT table to "Y". If the change takes an ID out of conflict, then I set the conflict flag in the MAINT table to "N". Basically my algorithm is:
1. get the OLD.id conflict record
2. get a cursor of all records except the old id conflict record.
3. compare the old id conflict recordd start and end times in the cursor, if there is a conflict in times, then update the record in the cursor and the old_id conlict to 'Y'.
4. get the new_id record (the one that changed).
5. Get the cursor of the new id records except the one that changed.
6. compare the new record to the cursor start and end times.
7. If conflict, update the new record and the one that it has a conflict with.
8. if not a conflict, update the new record.
I hope you can figure out what I am trying to say in a a generic sort of way.

I am sorry...
The trigger that I tried to come up with is:
CREATE OR REPLACE TRIGGER trgupdate_resource_id AFTER
UPDATE OF resource_id ON maintenance_resource_req FOR EACH ROW
DECLARE pragma autonomous_transaction;
BEGIN
UPDATE resource_schedules
SET resource_schedules.resource_id = :NEW.resource_id
WHERE resource_schedules.resource_id = :OLD.resource_id
AND resource_schedules.maintenance_id = :OLD.maintenance_id
AND resource_schedules.step_number = :OLD.step_number;
IF :OLD.resource_id = :NEW.resource_id THEN
IF :OLD.maintenance_id = :NEW.maintenance_id THEN
IF :OLD.step_number = :NEW.step_number THEN
IF((:NEW.scd_start BETWEEN :OLD.scd_start
AND :OLD.scd_end)
AND(:NEW.scd_end BETWEEN :OLD.scd_start
AND :OLD.scd_end)) THEN
:NEW.conflict := 'Y'
ELSE
:NEW.conflict := 'N'
END IF;
END IF;
END IF;
END;
END;
the table structures:
"MAINTENANCE_RESOURCE_REQ"
     "MAINTENANCE_ID" NUMBER NOT NULL ENABLE,
     "STEP_NUMBER" NUMBER NOT NULL ENABLE,
     "RESOURCE_ID" NUMBER,
     "PREVIOUS_RESOURCE_ID" NUMBER,

"RESOURCE_SCHED_ID" NUMBER NOT NULL ENABLE,
"RESOURCE_ID" NUMBER NOT NULL ENABLE,
"MAINTENANCE_ID" NUMBER,

NEED HELP WITH TRIGGER????

THIS IS TWO TABLE I NEED

I WANT TO REMOVE THE ON DELETE CASCADE AND REPLACE IT BY THIS TRIGGER
CREATE OR REPLACE trigger tr_del_meth_live before delete
on METHODS_LIVE referencing old as DELETEDMETHODS_LIVE
for each row
begin
DELETE from METHODS_NAME_LIVE

WHY I GOT THIS MESSAGES--->
ORA-04094: table TESTLA2.METHODS_NAME_LIVE is constraining, trigger may not modify it

THANK'S

Remove the foreign key, but u should implement the constraint by yourself in this case or do cascade delete operations on client side.

Need help with trigger comp err

i'm new to forms and triggers. I am trying to do a simple "select into" from the "previous" record so I can see what was the value of a column was and bump it up by one. The code for a post_text_item trigger is:
select
anum
from
x
where
x.pageid = :pageid;
the gist of the error is that the compile acts like it never heard of table "x", even though the form is built on table "x"! the err is - PDE-PSD001 - Could not resolve ref to unk program unit while loading block ...
any thoughts??
thanks in advance,
Burt

Sudha -
actually -
if the table I mention in the trigger contains an Ordsys.Ordimage column, the trigger blows. I guess the little procedure builder guy cant deal with the intermedia stuff too well/at all. I created a view from the table with the image, but didn't include the image in the view. I referenced the view in the trigger and everything went just fine.
thanks for your input

Help with Trigger - looping through SELECT results

How do I loop through a SELECT query within a Custom Trigger? I can
execute the query fine, but the PHP mysql_xxx_xxx() functions don't
appear to work inside a custom trigger. For example:
This ends up empty:
$totalRows_rsRecordset = mysql_num_rows($rsRecordset);
While this returns the correct # of records:
$totalRows_rsRecordset = $rsRecordset->recordCount();
I need to loop through the records like I would with
mysql_fetch_assoc(), but those mysql_xxx_xxx() don't seem to work.
This works great outside a custom trigger, but fails inside a custom
trigger:
do {
array_push($myArray,$row_Recordset['id_usr']);
while ($row_Recordset= mysql_fetch_assoc($Recordset));
What am I missing?

Although the create trigger documentation does use the word "must", you are quite free to let the trigger fire during a refresh of the materialized view. Generally, you don't want the trigger to fire during a materialized view refresh-- in a multi-master replication environment, for example, you can easily end up with a situation where a change made in A gets replicated to B, the change fired by the trigger in B gets replicated back to A, the change made by the trigger in A gets replicated back to B, in an infinite loop that quickly brings both systems to their knees. But there is nothing that prevents you from letting it run assuming you are confident that you're not going to create any problems for yourself.
You do need to be aware, however, that there is no guarantee that your trigger will fire only for new rows. For example, it is very likely that at some point in the future, you'll need to do a full refresh of the materialized view in which case all the rows will be deleted and re-inserted (thus causing your trigger to fire for every row). And if your materialized view does anything other than a simple "SELECT * FROM table@db_link", it is possible that an incremental refresh will update a row that actually didn't change because Oracle couldn't guarantee that the row would be unchanged.

Need help creating trigger with delete capabilities

I have two tables:
create table person(userid integer,
lname varchar(20),
fname varchar (20),
phone_number varchar(12),
email_address varchar(35),
city varchar(20),
zip_code varchar(20),
department varchar(20),
major_street varchar(20),
cross_street varchar(20),
notes varchar(100),
Primary Key (userid));
create table vehicle(car_id integer,
make varchar(15),
model varchar(20),
year integer,
gas_mileage integer,
capacity integer,
owner integer,
primary key (car_id),
foreign key (owner) references person (userid));
I am trying to create a trigger that would delete all those records in vehicle whenever someone deletes a record in the person table. Here is the code that I run but it get a compilation error. Here is the the trigger text followed by the error:
CREATE OR REPLACE TRIGGER ON_DELETE_PERSON
AFTER DELETE ON person FOR EACH ROW
BEGIN
DELETE from vehicle
where owner=userId;
END;
2/4 PL/SQL: SQL Statement ignored
3/19 PL/SQL: ORA-00904: "USERID": invalid identifier
Any suggestions?

CREATE OR REPLACE TRIGGER ON_DELETE_PERSON
BEFORE DELETE ON person FOR EACH ROW
BEGIN
DELETE from vehicle
where owner=:old.userId;
END;
