i want to create a trigger that will update a table when there is an insert or update.i can't across this error that i don't even know what it means "table %s.%s is mutating, trigger/function may not see it".
*Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
*Action: Rewrite the trigger (or function) so it does not read that table.
CREATE OR REPLACE TRIGGER set_date_end
BEFORE INSERT OR UPDATE OF issued ON shares_amount
FOR EACH ROW
DECLARE
BEGIN
INSERT INTO shares_amount(date_end) VALUES(SYSDATE);
END set_date_end;

i have two table:
QUOTE create table test1(
num number(4),
name varchar2(50));
create table test2(
num1 number(4),
name1 varchar2(50));
then i want to create a trigger before update on table test1 that i want to insert in table test2 the old values in table test1:
for example
QUOTE insert into test1(1,'cocol');
QUOTE update test1
set name='oracle' where num=1;
so i want the trigger to insert 1 and cocol into the table test2.

I have table test1(id,name) and table test2(id,,name)
Now when I update name column of a row on test1 I want the same value to be updated for the same id in test2.

I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?

i am trying to create a update trigger that allows any quantity reduction of 5 units and if the reduction is more than 5 units it blocks it and just reduces it by 5.here are two scenarios
SQL Update statement where the new Quantity value being smaller than 5 is allowed by the trigger.
-- old qty 20
update purchase_order
set quantity = 18
where po_no = 'PO11';
-- new qty 18
SQL Update statement where the new Quantity value being larger than 5 is only reduced by 5 by the trigger.
--old qty 25
update purchase_order
set quantity = 19
where po_no = 'PO15';
-- new qty 20
i just have the basic trigger code, but i think it is the math that i am not getting (i was never good at math)
create or replace trigger purchase_quantity_updt
before update of quantity on purchase_order
for each row
when (new.quantity < old.quantity )
begin
-- not sure what to put here
end;

I am trying to create and update query to use as a trigger for updating information in a database which is dependent upon time.
I have a severity level which needs to be decreased in value after a set amount of time. the time of the action is recorded automatically on the creation of the the record. after an hour anything at severity level 2 needs to go up to 1, after 2 hours level 3 goes up to 2 and 3 hours level 4 goes up to 3
so far this is what I have
UPDATE calllog
SET timedate = current_timestamp, severityid = severityid - 1
WHERE ((severityid = 2 and timedate >= current_timestamp + (1/24)) or
(severityid = 3 and timedate >= current_timestamp + (2/24)) or
(severityid = 4 and timedate >= current_timestamp + (3/24)))
I am not getting any errors back from this sql but it is not updating the relevent information. I am using one cell for time and date in format = DD-MON-YYYY HH24:MM:SS.

I am ceating a trigger to...when I update or insert a record in table and if salary of that record is less than 1600 than it should be updated to 2000. My trigger is
CREATE or REPLACE TRIGGER myTrigger
BEFORE UPDATE OR INSERT ON newemp
FOR EACH ROW
BEGIN
[code]...
There are no errors with trigger while compiling, but when I update or insert a record, it does not update the table. It looks like the trigger is being ignored.

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

Select * from Table A where emp=1;
Emp AID
1 111
select * from Table B where emp=1 ;
----------
AID, emp, start_dt, End_dt
111 1 01-jan-2011 31-dec-2011
112 1 01-jan-2011 31-dec-2011
113 1 01-jan-2011 31-dec-2011
I have After insert or update trigger on Table B. This will update AID column on Table B.
after insert update on table B
update A
set AID=:new.AID where emp=:new.emp;
if i end date any record on table B i wanted to update max(AID) on Table A.
EX update table b
set end_dt= sysdate-1
where aid=111;
So I wrote the trigger on Table A as below
before insert or update on trigger A
declare
v_aid number;
v_strt_dt date;
v_end_dt date;
begin
select max(AID) from table B
where emp=:new.emp;
select v_end_dt from table B where aid=:new.Aid;
if v_end_dt<sysdate then
:new.aid:=v_AID;
end if;
But the problem here is its giving mutating error.Then i tried with autonomus transaction but it willreturn old value when it fiers.
So how can i achive both the task at a time.That means i have to endate Table A , Same time i have to update active max(AID) to table B.

I am calling an after insert Trigger on table1.
In the trigger I am calling a procedure that returns an error if there is any error returned from procedure. I have to update the table table1's column error_desc (for the same new inserted record for which the trigger was called) with the error received by OUT parameter of procedure called in trigger. I have to update the same record on whose insert this trigger was called.

We would like to create functions to insert and update our tables and would like to make it not possible to update and insert the table directly outside of the function. Is there a way to do that in the trigger?

Is it possible to create table using trigger?
I tried but failed...
CREATE OR REPLACE TRIGGER tri1
AFTER UPDATE
ON dept
FOR EACH ROW
declare
pragma AUTONOMOUS_TRANSACTION;
BEGIN
execute immediate 'create table dept_dum as select * from dept';
END;
/
SQL> update dept set deptno=23 where deptno=10;
update dept set deptno=23 where deptno=10
*
ERROR at line 1:
ORA-01031: insufficient privileges
ORA-06512: at "SCOTT.TRI1", line 6
ORA-04088: error during execution of trigger 'SCOTT.TRI1'
I am running this as scott user
My requirement is to
create table as select * from table_name where flag=1
This has to be done parallel for all the tables for which this flag is enabled and by that trigger delete all those rows which were backed up as table.

In my DB,We have a table rqst_list
Create table rqst_list(id Number, --(PK)
pkg_name varchar2(100),
status varchar2(100))
When a record is inserted into this table(rqst_list), a trigger is fired which calls the package which is there in pkg_name.The function does some function.If there are no exceptions while executing the package, then SUCCESS needs to be updated in the table for the id for which the trigger got fired.I have used AFTER INSERT ROW level trigger.
But,the final UPDATE (UPDATE the rqst_list table to SUCCES/FAILURE)to the base table inside the package is not happening.

Table A basically has 4 rows of interest, an outside event changes/inserts let's say row 1.
Row 2 and 3 have to be changed in a trigger depending on the new value of 1.(or not if the value stays the same)
Row 4 is the reference for the update and will not be changed.
My first simple AFTER INSERT or UPDATE trigger obviously failed because of the mutating table error.

table
CREATE TABLE "TEST"
("CONTRACT_REF_NO" VARCHAR2(20 BYTE) primary key,
"CHG_GL" VARCHAR2(9 BYTE),
"CHG_GL_1" VARCHAR2(9 BYTE),
"CHG_GL_2" VARCHAR2(9 BYTE),
[code]...
10 rows selected.
create or replace view test_view
as
select 1 id,CONTRACT_REF_NO,chg_gl
from test
union all
[code]...
11 rows selected.
I have done only for one id.
so the problem is the front end is showing this test_view that people will modify.but they have to actually modify the table ,so I can think of an instead of trigger(instead of insert and instead of update ones).

I gave this a shot on my own, and failed, so I am putting the question to you:
I am looking to create a trigger on the "Account" table
CREATE TABLE Account(Acct_no number, BillAmt number, OpenDate Date, SSN number,
Primary Key (Acct_no),
Foreign Key(SSN) references ResponsibleParty(SSN));
which will update the BillAmt field whenever one of the account's respective records is inserted/updated/deleted from the following tables:
CREATE TABLE Plan(Plan_id number, Cost number, Minutes number,
primary key(Plan_id));
CREATE TABLE Feature(Feature_id number, Description varchar(20), Cost number,
primary key(Feature_id));
These tables are linked through the following table:
CREATE TABLE Phone_Line(MTN number, cStart Date, cEnd Date,
rDate Date, Status char, ESN number, Acct_no number, Plan_id number,
primary key(MTN),
foreign key(ESN) references Equiptment(ESN), foreign key( Acct_no) references Account(Acct_no),
foreign key(Plan_id) references Plan(Plan_id));

Using oracle 11.2.0.3 and wish to do the following.
Have trigger on table a on database a.
When a record is inserted into table a a record should be written first to table1 on database b , committed then a record written to table2 on database b as table2 has fk dependency on table 1.
How can we best achieve this.
Getting problems with the commit inside the trigger have tried pragma autonous transaction as well.
Get ora-02064 distributed transaction not supported when use the following code
create or replace trigger por_TRG_POP_IKNOW_MULTIPLE2
after INSERT OR UPDATE or delete on por_MULTIPLE
for each row
-- tO ENSURE I-KNOW KEPT UP-TO-DATE WITH HOMIS MULTIPLE
-- delib not delet form i-know as if has been used by customer cannot delete
-- due to referential inetgrity constraints in i-know
-- Note parent_num updated on IKW via support.maintain_latest_dim_version.update_multiple until
-- When IKW becomes master of multiple info, this trigger can be removed
-- and support.maintain_latest_dim_version.update_multiple removed
declare
PRAGMA AUTONOMOUS_TRANSACTION;
v_dml_type varchar2(1);
begin
IF INSERTING OR UPDATING
[Code]....
--when matched THEN update set
-- a.MGRP_NUM b.mult_link_multiple_num,
-- MGRP_DESCRIPTION = (select mult_name from por_multiple
-- where mult_code = mult_link_multiple_code
when not matched
then insert
(
a.MGRP_NUM,
a.MGRP_DESCRIPTION
)

My problem is the following:
At the time when P_delivery_date changes in P_ORDERS I want to transfer P_delivery_date to S_delivery_date in S_ORDERS for corresponding records.
Tables:
purchase orders table P_ORDERS:
P_order_number,
P_poz_number,
S_order_number,
S_poz_number,
P_delivery_date
sales orders table S_ORDERS:
S_order_number,
S_poz_number,
S_delivery_date
My question is:
Is it possible and what would be the solution using the TRIGGER on table P_ORDERS to update S_delivery_date with P_delivery_date in S_ORDERS?

I'm trying to create a trigger so that whenever a record in the Employee table is deleted, a trigger will automatically delete corresponding records in the Job History table, then the Employee record is archived to EmployeeArchive before it is deleted. It compiles but with warnings. Here's what I've got.
CREATE TABLE EmployeeArchive
(EmployeeID Int, FirstName Char, LastName Char,
EMail Char, PhoneNumber Int, HireDate Date, JobID Char, Salary Int,
Commission Int, ManagerID Int, DepartmentID Char);

I would like to create a trigger on a table which populates a log table. In addition to using the table where the trigger will exist, I would like to populate a couple more fields in the log table with with data from 2 other tables.
e.g.
NAME_TABLE
-reg_id
-name
ADDRESS_TABLE *trigger to be fired when a new record is created here.
-reg_id
-srv_id
PROCESS_TABLE
-srv_id
-start_time
-end_time
This is what I would like the logging table to look like:
LOGGING_TABLE
-address_table_reg_id
-address_table.srv_id
-name_table.name
-process_table.start_time
-process_table.end_time
How can I go about creating this type of trigger?

I have three tables fixtures, fixture_teams and team_tbl
fixtures consists of:
create table Fixture_tbl(
fixt_id varchar2(8),
fixt_date date,
fixt_time varchar2(10),
fixt_location location_t,
umpire_id varchar2(8),
player_of_match player_of_match,
home_team varchar2(20),
away_team varchar2(20),
[code]....
creating a stored procedure that updates the points column in the teams_tbl , the value that is updated in to the points column will be retrieved from the fixture_team table. so if team a has more goals than team b then the points column for team a will be increased by 6 else if the scores are equal they get 4 points each.

After many tests I can't make work and update of the same table inside the same table.
Trying to avoid Mutating Table Error now I have
ORA-00036: maximum number of recursive SQL levels (50) exceeded
Sample Data :
create table test_compound (USERID VARCHAR2(10),APP VARCHAR2(15),LAST_UPDATED_ON TIMESTAMP);
insert into test_compound values ('user1','1',systimestamp);
insert into test_compound values ('user2','2',systimestamp-4);
insert into test_compound values ('user3','3',systimestamp-6);
CREATE OR REPLACE TRIGGER trigger_test
FOR UPDATE ON test_compound
COMPOUND TRIGGER
TYPE t_tab IS TABLE OF VARCHAR2(50);
l_tab t_tab := t_tab();
[code].......
When I execute :
update test_compound
set last_updated_on=systimestamp
where userid='user1' and app='1';
The trigger should update the first row and all the data from test_compound table where userid='user1'. Maybe the problem is that updating the same table inside the trigger is firing in a recursive way the trigger.

I have one table with one row with some coefficients. If I update a coefficient from my table I want to be updated all the rows from another table. I've made a trigger but in the second table I have a column for example TOTAL and I want that column to be multiplied with my new coefficient, and I want this for every row in the second table. How I can select that total column in the trigger for every single row and update it?
