How To Write Trigger In Oracle 10g
Apr 12, 2011
I am using SQL*Plus to run this Oracle10g. Here is my problem I have to solve: After a new record is added to the task table, write a trigger that reports the new project balance to the user while updating the customer balance to reflect this additional task cost. Insert a new record to show the trigger works. I somewhat understand triggers,I think I have to combine tables to solve this. Here are my tables/attributes I can use to solve it:
CREATE TABLE customer
(
custnoNUMBER(3)CONSTRAINT ccustpk NOT NULL PRIMARY KEY,
custname CHAR(20) CONSTRAINT ccustnamenn NOT NULL,
phone CHAR(12),
curr_balance NUMBER(9,2) CONSTRAINT ccustbalancenn NOT NULL
[code]...

I want to write a trigger to validate the v_status for each ID. below is the example
SEQ_NO ID V_STATUS
11 C
21 C
31 F
42 C
52 F
63 C
7 3 F
8 3 C
For each unique id there will be only one F .. if some one tries to update the 2nd F to the same ID it will show the error message that ID is already F.
SEQ_NO ID V_STATUS
11 C
21 C
31 F
42 C
52 F
63 C
7 3 F
8 3 F

I have to write a trigger on a table which contain lot of parameters.But i need to pick a specific row and check that without disturbing other stuffs.Is there a way to write Before update trigger on a particular rows filtering the unneccasary rows.
The requirement is when user update the date from front end (Java application) the trigger should check the date and validate that it should be month end date. For example.
1)04/21/2012 wrong date
2)04/30/2012 correct date
3)03/29/2012 Wrong date
4)03/31/2012 correct date

I am trying to write a trigger on a new table. (dest_test) This is the first trigger that I have ever attempted (fairly new DBA) and I am having some trouble with the trigger body.It is a before insert trigger that will need to select from another table (dest) for a particular value being inserted (destination).
create table dest_test (
destination varchar2(4) not null,
db_name varchar2(10) not null
)
desc dest
[code]...
I am getting the exact opposite results than I want, though. If the value appears in dest, it is inserting into dest_test... NOT whatI want it to do!If the value doesn't appear in dest, it is throwing ora-6512 and ora-4088 errors. Is there a way to suppress these errors, or to graceful exit from the block so that the trigger completes without throwing these errors?

When you create a backup in SQL Server, whether the backup is on disk or on tape, SQL Server writes the letters TAPE to the first four bytes of the backup. Does Oracle write any specify value to the front of every backup, and if so, what are the first four bytes?

I am using commit in a trigger as given :
create or replace
trigger comt after insert on tbl_city
declare
pragma autonomous_transaction;
begin
commit;
dbms_output.put_line('Value is committed');
end;
Now when I perform an insert in tbl_city---->trigger fires properly and gives output stream. But If I perform rollback now --->there are the data rollbacked in table.
why?I think after commit(which is in trigger associated at insert to table)there should no any rollback in table.

I am working with an oracle table that is populated by a trigger on another table.. So Table A is an audit of table B. The trigger also uses sysdate to populate a modification Date column on the Audit table.
I was using this modification Date column in a query interface to get changes that happened on the main table after a certain date/time.
The problem is that there is an application that uses transactions to write to table B and sometime this transaction may not be committed for over a minute so the modification Date is not a reliable way to query the table for changes after a certain time.
Is there a way to update the trigger/create a new one where the sysdate that gets written to the audit table is from when the transaction is committed, not when the transaction starts?

I am trying to create some PL/SQL that will create a trigger for UPDATES and INSERTS which will update a column on the same row to the system date.
So far I have:
DECLARE
tablename VARCHAR(30) := 'table';
triggername VARCHAR(30) := 'mytrigger_' || tablename;
[Code]....
I have declared the tablename and triggername outside the trigger creation as I need this to be parameterised for a list of tables.
The procedure IsCDCUser just checks it should be updating for this user.
The problem I get is the following error:
Bind Variable "NEW" is NOT DECLARED

I am writing a after trigger for one of my tables on every insert update and delete for my dataware house staging area. The process here is when ever there is a change in the production database we need to capture this change in our changing area through triggers.
I am able to create the triggers but i am stuck with the exception handling portion of the trigger. I want to write an exception in the trigger where when the staging area is locked or for any other matter the data needs to be able to go to a error table when the staging area is not able to accept the data for some reason.
how i can write this excepyion in the trigger or anyother method i can follow to be able to handle this scenerio.

I have an update trigger that runs a package when fired. I only want this package to run if it is NOT fired from an Oracle Forms application. Ie. A user might update table ABC from an Oracle Form. In this instance the trigger would fire, but I don't want to run the package within the trigger. If the user logs onto PL/SQL developer and updates the table, the trigger would fire and the package must run.
I was thinking of using the field 'program' from v$session. If it is null (it's being fired from an Oracle Forms application) if it has a value (it's coming from SQL*Plus / Pl/sql Developer).

I must create an INSERT trigger, on an Oracle table, which will do an insert into my MS-SQL 2000 DB table.
The tables are exactly the same in this case and I desire to insert the entire row that was just insterted into the Oracle table into the MS-SQL table.
I understand how to create an ODBC connection between the DB servers, I just can't seem to understand the trigger syntax.

I need to fire the KEY-DUPREC trigger as I click on the key combination Shift+P therefore; I added the following line of code in the frmweb.res file.
80 : 1 : "Shift+P" : 64 : "Duplicate Record"
It worked iff no error was raised. So, if I have a raise form trigger failure in the KEY-DUPREC trigger, a capital P will appear in the text field that called the trigger.
