SQL & PL/SQL :: Prevent Duplicate Column Value Using Trigger
Mar 8, 2010
I want to avoid duplication on old_nic_no and new_nic_no number in a Table, for this i am using a following trigger
create or replace TRIGGER chk_ip_duplications
BEFORE UPDATE
ON cb_insured_person_bak
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
[Code]...
when i use following command
update cb_insured_person_bak set new_nic_no = '34601-0774284-9' where eobi_no = '4300G043746'
34601-0774284-9 already exist with another eobi_no , i expect error described in rise_application_error clause but i give following error
ORA-04091: Table cb_insured_person_bak is mutating..........
How i can resolve this problem.....

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?

below are the create and insert statement, making duplicate row, i mean In table emp_detail, we have row like
ENAMEJOBDEPTNODETAIL
RAJ CS 10 RAJ IS IN CARE OF ROHIT
We need to insert the same record but divide the last column value on the basis of "IN CARE OF" any word after this should come in next new row with the same value for all other column, like
ENAMEJOBDEPTNODETAIL
RAJCS10RAJ IS IN CARE OF
RAJCS10ROHIT
CREATE TABLE "EMP_DETAIL"
("ENAME" VARCHAR2(10),
"JOB" VARCHAR2(9),
"DEPTNO" NUMBER(2,0),
"DETAIL" VARCHAR2(100)

I have a table with multiple columns and I need to retrieve the ones where column a stores duplications for records where column b is discrepant
this is the table
NAME_ID PHONE_NUMBER
12345 +41 22 595 5555
12345 +41 22 595 5555
12342 +41 22 595 5500
12340 +41 22 595 5555
the query should return
NAME_ID PHONE_NUMBER
12345 +41 22 595 5555
12340 +41 22 595 5555
The closest I got was with the below, but this also returns duplicates within the same NAME_ID.
select phone_number, name_id
from name_phone
where (phone_number) in
(select phone_number
from name_phone
group by phone_number
having count(*) > 1)
group by phone_number, name_id
order by phone_number

I am trying to create a trigger which changes the content of one column based on the information within another column.
For Example, if the 'ITEMQUANTITY' field drops below 1 then I want the STATUS column to say 'Out Of Stock'.

I'm going to do some testing, and for that I require to retrieve some data based on a single column e.g test_data_col, which -
1. Has 3 or more count(test_data_col) for a given set of group by columns e.g grp_col1, grp_col2, grp_col3
2. Within the set of rows retrieved, that particular column holds some duplicate values. I don't need the duplicates displayed, just know if duplicates exist or not.
This might explain what I'm trying to do -
grp_col1, grp_col2, grp_col3, test_data_col
1, A, xyz, HELLO
1, A, xyz, HELLO
1, A, xyz, BYE
1, A, xyz, GOODBYE
2, C, pqr, WELCOME
2, C, pqr, GOOD MORNING
2, C, pqr, BAD MORNING
So for condition 1, I do something like this -
SELECT COUNT(test_data_col) cnt, grp_col_1, grp_col2, grp_col3
FROM test_tab
GROUP BY grp_col_1, grp_col2, grp_col3
HAVING COUNT(test_data_col) >= 3;
In this same query, I want to do something that will tell me if the aggregate COUNT(test_data_col) has any duplicate values within it. Again, displaying the duplicates is not important here.
SELECT COUNT(test_data_col) cnt, grp_col_1, grp_col2, grp_col3,
/*some logic*/ dup_val
FROM test_tab
GROUP BY grp_col_1, grp_col2, grp_col3
HAVING COUNT(test_data_col) >= 3;With the proper coding to replace /*some logic*/, I get following values -
cnt, grp_col_1, grp_col2, grp_col3, dup_val
4, 1, A, xyz, Y
3, 2, C, pqr, N
I just gave dup_val column to explain what I'm trying to achieve.. any other way to know the existence of duplicates in the count aggregate will be fine.My Oracle version is Oracle Database 11g Enterprise Edition Release 11.1.0.7.0

I have a form which utilizes 2 canvases that the user can toggle between. There is a database column that I would like to have appear on both and be updatable from either place. In my search here first, I found where I could set up a non-database item and copy to it at the point of Post-Query...and that comes close, but I need both columns to not just reflect the db column but be able to update it.
I am about to try using a second trigger to move things from a non-DB column to a DB-column next, but just wondered if there is a better way. When I first compiled with the designer the duplicate column I set up as a DB column also. It only gave me warnings (that I could have lived with) but the ultimate compile my system does outside of the designer calls it an error.

I have 4 reports on the same page. I have added a checkbox column to each one. On clicking I want to populate a collection with the value of the id of the corresponding row and then have a button acting on the whole list.
My code to get the id of the item that contains the value I want is this
id = 'f02_' + $(this.triggeringElement ).attr('id').substr(4,4);
But there is an f02_0001 for each report, and the code just finds the first one, rather than the one in the context of the report being clicked.
<input name="f02" id="f02_0001" type="hidden" value="2072"/>
....
<input name="f02" id="f02_0001" type="hidden" value="2052"/>
...
etc etc.
All that is ever picked up is 2072
They have different table ids but I don't know how to reference the correct ones in my code.

I am working on convertion of triggers from SQL SERVER to Oracle. I got them converted using a tool. But not sure how to correct the below trigger which uses '*' in sql server.
Code in SQL SERVER :-
CREATE TRIGGER INSERT_AUDIT ON T_AUDIT
FOR INSERT AS
INSERT INTO T_AUDIT_LOG
SELECT 'INSERT','AFTER', CURRENT_TIMESTAMP, NULL,*
FROM INSERTED
Converted into Oracle:-
CREATE OR REPLACE TRIGGER INSERT_AUDIT
BEFORE INSERT
ON T_AUDIT
FOR EACH ROW
INSERT INTO T_AUDIT_LOG
VALUES ( 'INSERT', 'AFTER', SYSTIMESTAMP, NULL, * );
END;
how can I remove the *. I tried replacing the * with the rest column names prefixing with :NEW.
the last 3 columns when are c_data1,c_data2,c_data3 as :-
INSERT INTO T_AUDIT_LOG
VALUES ( 'INSERT', 'AFTER',SYSTIMESTAMP NULL, :NEW.c_data1,:NEW.c_data2,:NEW.c_data3);
But this gives error:-
PLS-00049: bad bind variable 'NEW.C_DATA1'
PLS-00049: bad bind variable 'NEW.C_DATA2'
PLS-00049: bad bind variable 'NEW.C_DATA3'
how can I convert this code.

I have a non-base-table item which I want to update in the pre-update trigger of the current block.
If the content of the field exceeds 4000 characters, i get the error message
ORA-01461: can bind a LONG value only for insert into a LONG column.
The code is
update tab set long_col = :formsblock.long_col
where tab.tabpk = :formsblock.foreign_tabpk;
Workarounds would be,
1.) to delete the old dataset and insert the new one:
delete from tab
where tab.tabpk = :formsblock.tabpk;
insert into tab (tabpk, long_col) values
(:formsblock.foreign_tabpk, :formsblock.long_col);
or 2.) to change the Item from a non-database item to a database item and use the internal update of the forms-module, but both workarounds are not very satisfying.
Do you know another way to update the LONG-column within the pre-update trigger (or any other PL/SQL part of forms)?

Form has insert and delete enabled.
I would like to prevent the deletion of a record based on some column value.
Something like:
IF (COLA value < 10) THEN
SHOW ALERT;
RECORD IS NOT DELETE
ELSE
DELETE RECORD AS NORMAL
END IF;
I want this to happen even before the record is marked for deletion, but I don't know where to put it. I tried a pre-delete trigger, but it does not work they way I want.
