I have a table known as Registration in which there are columns StudentID, ModuleId, year, semester
semester = 1 or 2
I want to write a trigger so that student can register on a maximum of 4 modules per semester
i.e.
select count(*), semester from Registration where studentid='241234' group by semester
I tried the following trigger but I am stuck
If I dont use "for each row", I am not allowed to use :new and ld and when I use "for each row", count would be for each row which would be 1 or 0
create or replace trigger checkmodulecount
before insert on Registration
DECLARE
noCourse NUMBER;
nCount NUMBER;
FAILED EXCEPTION;
[Code]....
WHEN FAILED THEN
raise_application_error(-20000,'Cannot reigster for more than four courses');
END;

I have to write a trigger where when the table is updated then one column named 'Status' should be updated as 'U' and if arow is inserted in the table then the column 'Status' needs to be inserted with value 'I'.
Create table test_trig
(
vempno number,
vempname varchar2(20),
status char
)
New to triggers....how to go with both insert and update conditions together.
Can we write a trigger which takes care of both insert and update. I have used Merge statement where I can write conditions based on insert/update done.

In
CREATE table ALPHA (
ID NUMBER,
FK_NR NUMBER,
INPUT NUMBER,
OUTPUT NUMBER,
MY_COUNT NUMBER,
ACTUAL_TOTAL NUMBER
);
I would like to record new inputs or outputs andthe column MY_COUNT should display the actual count of records for INPUT (actually MOD(INPUT, 10) ) regarding FK_NR and ACTUAL_TOTAL should display the actual sum for all input/output for FK_NR.
--ID normally comes from a sequence and BEFORE INSERT TRIGGER
EXAMPLE
INSERT INTO ALPHA(FK_NR, INPUT, OUTPUT)
VALUES (1 ,10,NULL);
INSERT INTO ALPHA(FK_NR, INPUT, OUTPUT)
VALUES (1 ,10, 50);
[code]...
Table ALPHA looks like:
1,1,10,NULL,1,10
2,1,10,50,2,-30
3,2,NULL,20,0,-20
4,2,20,40,2,-40
5,3,40,20,4,20
6,3,-10,NULL,3,10
How can this be achieved ?I started with a
CREATE OR REPLACE
TRIGGER "BI_ALPHA"
BEFORE INSERT ON ALPHA
FOR EACH ROW
BEGIN
SELECT ALPHA_SEQ.nextval INTO :NEW.ID FROM DUAL;
END;
and thought of a
CREATE OR REPLACE TRIGGER "AI_ALPHA"
AFTER INSERT ON "ALPHA"
FOR EACH ROW
DECLARE
l_maxidNUMBER;
l_fknr NUMBER;
[code]...
But by inserting a row, this results in ORA-04091

I'm trying to insert data in my_second_table using a trigger and a view when I insert the data in my_first_table but there's something wrong in the code.
CREATE OR REPLACE TRIGGER my_trigger
AFTER INSERT ON my_first_table
FOR EACH ROW
BEGIN
[Code]...
I'm suspecting that the problem is in the :new.cod_emp
P.S.: I'm using: Oracle Database 11g Release 11.2.0.1.0 - 64bit Production on Enterprise Linux Server release 5.5 (Carthage)

writing a trigger body. My requirement is i need to insert a new record in a task table when ever a new record is inserted into employee table.Here in the trigger i need to select the name of the employee in the last inserted row in employee table and insert the name in task table.I tried to write the code as below
insert into task(name, date, type) values ((select name from employee where emp_id=(select max(emp_id) from employee), sysdate, 'document'));
When i am trying to insert record using trigger, it is taking last but one record from the employee table.

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.

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 am trying to write a trigger that will do an insert/delete/update into a audit table when a change has occurred on the primary table. The change will be recorded in the audit table by a incemental sequence number and the updated data.
there will be an extra column in the audit table
how to get a simplified version of this trigger.
the primary table will look like so
Id_num varchar (20)
code Integer
desc varchar(20)
sequence_num Integer
audit table
Id_num varchar(20)
code Integer
desc varchar(20)
timestamp date
sequence_num Integer

I hit a bottleneck where my insert trigger won't execute the insert statement (with subquery). See illustration below:
Step# 1 - Table definition:
Table_A(a1 number, a2 varchar(10), a3 varchar(10))
Table_B(b1 number, b2 varchar(10), b3 varchar(10))
Table_C(c1 number, c2 varchar(10), c3 varchar(10))
Step# 2 manipulated the tables:
Inserted 3 records in Table_C.
Then I created an Insert Trigger to Table_A with an insert statement into Table_B and a subquery to Table_C. Please see below:
CREATE OR REPLACE TRIGGER TABLE_A_TR
after INSERT OR UPDATE OR DELETE ON TABLE_A
FOR EACH ROW
DECLARE
[code]......
Step# 3 compiled the created trigger and I've successfully compiled it.
Step# 4 Tested the trigger (TABLE_A_TR) using an insert statement to TABLE_A.
Insert into TABLE_A values (1,'testa','testb')
I've successfully insert the values into TABLE_A however I've observed that the trigger didn't execute the insert statement because TABLE_B has an empty rows. I tried to manually execute the insert statement just to see if there's an issue in my insert statement but I've successfully populated the values into TABLE_B. So I'm wondering why the trigger didn't execute the insert statement.

I have three tables.
One for projects, one for volunteers, and a bridge entity for the many to many relationship between the Project and Volunteer.
In Project table, I have a field called, Volunteers_currently_signed_up, which means the number of volunteers currently signed up to participate in a project.
When I add an entry to my bridge entity which is composed of Volunteer_ID and Project_ID, I want the Volunteers_currently_signed_up to increment by 1, where the Project_ID in the bridge entity corresponds to that in Project.
I have very very little PL/SQL, and this is my amateur attempt so far:
CREATE OR REPLACE trigger "BI_Volunteers_currently_signed_up"
BEFORE INSERT OR UPDATE ON Volunteers_in_project
for each row
WHERE Volunteers_in_project.Project_ID=Project.Project_ID;
begin
Project.Volunteers_currently_signed_up += 1;
end;
/
write a trigger that achieves the above

I have 2 table events and concerts. The event table has event_id, concert_id and event_date fields, the concert table has concert_id, name, artist, type and cost.
I need to insert a trigger that 'jazz' concerts cannot be run in January. This is my attempt:
CREATE OR REPLACE TRIGGER rock_december
BEFORE INSERT OR DELETE OR UPDATE ON event
FOR EACH ROW
IF event.type = 'jazz' and AND ((event.event_date) BETWEEN
'01-DEC' And '31-DEC'))
RAISE_APPLICATION_ERROR(-20100,'Jazz event can not be booked in January');

I have written trigger to satisfy the requirement, when i write row level it comes out with mutating error on table which is very obvious, i have change it to statement level which is fine but it doesn't satisfy the requirement.
I want to capture the id column , which rows got inserted or updated .
Is there any way to get the newly inserted or updated rows as in case of row level i can get it form :new.id.

I have to insert many computed rows (not coming from a select...where...) into a target table.
I wrote a code like the following example; it works but it seems to me not efficient:
WHILE l_data < l_dt_end
LOOP
l_value := MY_FUNCTION( l_data );
l_color := MY_COLOR( l_data );
INSERT INTO MY_TARGET
( value, color )
VALUES( l_value, l_color );
l_data := l_data + 1;
END LOOP;
COMMIT;
EXCEPTION
...
ROLLBACK;Which is the best way to write this?

In a trigger(on update of a table t1) I am trying to write, I am doing an insert on t2 accessing ':new' values of the update on t1.
But in my Insert statement, I am having get one of the column values from another table. How can I write my insert statement in such a way as to insert values contained in ':new' pseudo columns and a select from another table. Below is my insert statement in the trigger :
-------
IF (:old.GROUP_YELLOW <> :new.GROUP_YELLOW) THEN
INSERT INTO TEST.W_THRESHOLD_LOG
(THRESHOLD_LOG_WID, CHANGE_DATE, MEASURE_TYPE_WID, MEASURE_NAME, CUSTOMER_WID, CUSTOMER_NAME, USER_ID, CHANGED_ITEM, PREV_VALUE, NEW_VALUE)
VALUES(TEST.W_THRESHOLD_LOG_SEQ.NEXTVAL, SYSDATE, :new.MEASURE_TYPE_WID, 'Rolling Stabilty' , :new.CUSTOMER_WID, 'Customer1', 'User1', 'GROUP_YELLOW', :old.GROUP_YELLOW , :new.GROUP_YELLOW);
END IF;
-------
In the above code if the hardcoded value 'Customer1' need to be picked from another table,
i.e .
SELECT NAME FROM W_CUSTOMER_DIM WHERE CUSTOMER_WID = THRESHOLD.CUSTOMER_WID
how can I rewrite my query to the above value from the select into my insert statement..?

I know this is an old thread and I just started working with triggers. I want to check if the data being inserted is already in the table and if not insert it:
create or replace trigger t_triggername
before insert on tbl_tablename
for each row
begin
if(:new.user_id <> :old.user_id) then
insert into tbl_tablename(user_id, location)
values (:new.user_id, :new.location);
end if;
end;
what if I wanted to keep the user but only update location if the user is already in the table. I've tried doing it this way:
create or replace trigger t_triggername
before insert on tbl_tablename
for each row
begin
if(:new.user_id <> :old.user_id) then
insert into tbl_tablename(user_id, location)
[code]...
