SQL & PL/SQL :: Compound Trigger Equivalence?
Jun 23, 2011
I have a table T_TEST, i will update the table rows, i want to add a single record in some other table let say T_A, which contains the sum of the updated difference of all the records.
let say, if i have T_TEST with values of 100, 200 and if i update it to 500, 600 (oldvalue+200) then my T_A should contain a record which is 400.
I was able to implement the solution in Oracle 11.2.0.1 using compound triggers. I would like to know how to do it in earlier versions of oracle or Is ther any other way to do it.
create table t_test ( a number);
begin
insert into t_test values (200);
insert into t_test values (200);
insert into t_test values (200);
insert into t_test values (200);
[code]...

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 am have a problem with Oracle user equivalence. long time ago, we have created Two node RAC. that time, we configured Oracle user equivalence.
today when i am trying to install Oracle Agents on this RAC pair, installation was failed due to Oracle user equivalence. not sure how it happened, and i was confused too.
if i configure Oracle user equivalence again, will it cause any problem to my RAC setup?
is there any way to find, when was the Oracle user equivalence was changed/ ssh keys got changed?

I have rather large compound triggers that I discovered were not firing this morning, so I created a simpler compound trigger to test:
CODECREATE OR REPLACE TRIGGER "test"
FOR INSERT OR DELETE OR UPDATE OF KI_NM ON CHEMAXON.CB1ASSAYS
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
ENABLE
[code]...
It's just not firing. The tables are all in the owner's schema (who has DBA rights). My Google-fu is failing me, and I'm not sure how to start troubleshooting general trigger failure.

CREATE TABLE TEST
(
EMPNO NUMBER,
SAL NUMBER
)
/
CREATE TABLE SUMSAL
(
[code].....
Say I have emp table. Now what I want is that whenever I enter new records in EMP table, I want to sum up the value inserted for SAL column and I want to do some task based on that value.
I'm inserting the EMPNO and SAL in test table whenever a row is inserted in EMP table. Now from there I want the SUM(SAL) column. As you can see I took the sum and inserted it into another table (or I can update a packaged variable with this value). It is inserting as many rows in SUMSAL table as many I insert in emp table through Oracle Forms. I want it to insert only one row in SUMSAL table because after user enters all the data for EMP table, I want to capture the sum of Salary inserted and then I want to perform some tasks based on that value.
SQL> select * from test
2 /
EMPNO SAL
---------- ----------
1111 100
2222 200
SQL> select * from sumsal
[code].....
-- Here it should be only one value. i.e: Sum(SAL) column. That is 300. But whatever task I want to perform it performs it for each row inserted. But I want to perform it after trigger inserts all the rows in TEST table.
I wrote an after insert trigger at table level but still I'm getting the same result.

I am trying to use execute immediate in a trigger. See the below example
create table test_tbl(col1 number,col2 varchar2(10), col3 date);
create table test_tbl_log as select * from test_tbl where 1 = 2;
create or replace trigger test_trig
after insert or update or delete on test_tbl
for each row
declare
v_str varchar2(4000);
[code].......
insert into test_tbl values(3,'test',sysdate);
I got the Error : -1008->ORA-01008: not all variables bound
In the execute immediate statement if I change the v_using_str variable to :new.col1,:new.col2,:new.col3 trigger is running fine. But here I have to create trigger on all the tables in my schema and I dont want to list all the column names for each table manually and I am using a for loop to build the v_using_str string in my original code.

I have created a trigger for after insert which updates a table when there is a row inserted in that table. The update is on a column which stores the application description along with the sequence number. Now my requirement is that sequence number should be unique only with in an application but not with in the table.Say the row entry can be as follows:
App_Desc Request_ID
-----------------------
DEV 100 1
DEV 101 2
STG 100 3
STG 101 4
Here Request_ID is unique But the sequqnce thats created for DEV (100,101) should take an entry of 102 for the next entry for DEV and same applies for STG. So I have to use the same sequqnce for all the application.

consider the trigger below,
CREATE OR REPLACE TRIGGER PPMAPP.PPMCR_HH_CHR_TRG
AFTER UPDATE
ON PPMCR_STEN.PPMCR_HH_CHARACTERISTICS
[code].....
The cursor HH_ATTR_CSR returns a set of values and I'm iterating each values using a loop, but when comparing the post and pre values, I have to use the variable(HH_ATT_VAR) instead of column names.Usually we give it as (re.XXXX_YYYY) but the cloumn names has to be given in the form of a variable got from the cursor like (re.HH_ATT_VAR).In doing so, I'm getting an error as "bad bind variable" So,Is there any to view the old and the new value in the local?

I have 3 tables whose structure is as follows:
1) Invoice
Invoice_no number(8),
Debtor varchar2(35),
Invoice Date Date,
Print Date Date,
Currency varchar2(3),
Total Amount Ex Number(11,2),
Total Amount Vat Number(11,2),
Total Amount Number(11,2),
Status Varchar2(15),
2) Invoice Line
Invoice_no number(8),
Invoice_Line_No number(8),
Description_1 varchar2(35),
Description_2 varchar2(35),
Line_Quantity Number(11,2),
Currency varchar2(3),
Line_Amount Number(11,2),
Vat Code number(1),
Status Varchar2(15),
3) vat code
vat code number(1),
Description varchar2(35),
Vat Percentage number(11,2)
Here invoice no and invoice line no are automatically generated fields?
How to generate invoice line no corresponding to invoice no and how to satisfy the following conditions:
1) total vat amount in invoice table should be automatically filled . total vat amount=(line_quantity* line_amount*vat percentage)/100
2) invoice cannot be printed, changed when status is 'closed'.
3) invoice lines cannot be added,changed or removed when status of invoice is closed
4) when any of invoice line no is changed,added, removed or invoice is changed the status of invoice should be changed to 'new'.
5) invoice date of a new invoice cannot be of the past

Basically, I need to fulfil the constraint:
"student cannot have more than 100 points"
I need to use a trigger to do this, but I don't understand how this would work.
Written in plain english I imagine it work work something like:
AFTER UPDATE
WHERE student.lessonid = lesson.lessonid
IF SUM(lesson.points) > 100 then ROLLBACK
lessonid is the only field relating the two tables.
--
How to fulfill that criteria, whether it be using triggers or not.

I need to create a trigger for the below case:
index_id Time_vertex_id date rate pre_rate
4 1 17-06-2011 4.7 6.4
4 1 16-06-2011 6.4 7.4
4 1 14-06-2011 7.4
4 1 15-06-2011 8.4 7.4
the index_id and time_vertex_id will be unique and when the date is 17th i.e the first date will be inserted the current rate will be 4.7 and the previous rate will be blank and when another date is inserted i.e 16th the previous rate of 17th will be the current rate of 16th i.e 6.4.
when 14th is being inserted, the previous rate of 16th will be the current rate of 14th i.e 7.4 and if after 14th is being inserted, 15th is being inserted, then the previous rate of 16th should be updated as per the current rate of 15 say 8.5.

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?

I have a table which has a trigger defined as such on the Main table.
before INSERT OR UPDATE OF USER_NM,COmpany_ID,UPDATED_BY_USER
OR DELETE ON MAIN TABLE OLD AS OLD NEW AS NEW
FOR EACH ROW
When I insert the 1st row (by user Scott)
MAIN TABLE
USER_NM CompnyID UPDATED_BY_USER
----------------------------------------------------------------
ABC1Scott
In the audit table I have this information:
USER_NM CompnyID UPDATED_BY_USER OPERATION_PERFORMED
----------------------------------------------------------------
ABC 1 ScottInsert
When an ADMIN user (other than Scott deletes the above row)
MAIN TABLE:
USER_NM CompnyID UPDATED_BY_USER
----------------------------------------------------------------row deleted....
In the audit table i have 2nd entry as:
USER_NM CompnyID UPDATED_BY_USER OPERATION_PERFORMED
----------------------------------------------------------------
ABC 1 ScottInsert
ABC 1 ScottDELETE
Here the updated_by_user is Scott and not ADMIN, even though I am doing the following in the trigger.
UPDATED_BY_USER := sys_context('USERENV','OS_USER')
I want to show the user who has deleted the record which should be ADMIN.
Since the user deleting may not be the samae as the one who inserted.Any clue?

I have the following problem.
I have a trigger "before update" that change some values, including a timestamp column. My sql code does an update using the "returning clause" to get the values changed by the trigger. The problem is:
When I do an "update [...] returning timestamp_field", this timestamp_field has the old value equals to null (in the trigger). And, this field in the table is not null. This problem not occurs with the others fields of type number, varchar... only with the timestamp field.
Here are the code to simulate this problem:
--Table
create table TB_TEST
(
ID NUMBER(10) not null,
FLAG NUMBER(10) not null,
TAG VARCHAR2(16) not null,
TS_ATU_DTR TIMESTAMP(9) not null
);
[Code]..
Testing
exec test1;
select * from textolog order by data, texto;
Output:
DATA TEXTO
--------- ----------------------------------------------------------------------------------------------------
15-FEB-11 1:old.FLAG=123, :new.FLAG=321
15-FEB-11 1:old.TAG=teste trigger, :new.TAG=teste trigger
15-FEB-11 1:old.TS_ATU_DTR=, :new.TS_ATU_DTR=
15-FEB-11 2:old.FLAG=123, :new.FLAG=321
15-FEB-11 2:old.TAG=teste trigger, :new.TAG=10
15-FEB-11 2:old.TS_ATU_DTR=, :new.TS_ATU_DTR=15/02/2011 11:07:38.094284000
-----
"old.TS_ATU_DTR=, " Isn't it right?????
Why the other fields aren't null?
I need the "old.TS_ATU_DTR" to use in my other trigger to compare timestamps, how can I get it?
Or, is there a patch for this problem?

The below trigger is running fine without any error ,but i wasn't able to perform the exact logic by the below trigger.IF, inserting multiple row then the SIVNUM field gets the same sequence number for each row , without incrementing the value for the next row.
Only the sequence value increases on the next set of row ow's inserted
Example (inserting 2 rows ) based on the below trigger:
item , refwo , sivnum
1234 , 55555 , 00001
6352 , 77777 , 00002
i want to achieve :
item , refwo , sivnum
1234 , 55555 , 00001
6352 , 77777 , 00001
CREATE OR REPLACE TRIGGER siv_mat_insert
BEFORE INSERT
ON MATUSETRANS
REFERENCING OLD AS old NEW AS new
for each row
[code]....

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 written small procedure here...
I used two tables in my procedure..TBLEMP and TBLORG..
STEP I :->
I try to insert record in both table TBLEMP and TBLORG...I written seperate BEGIN and END block for TBLEMP and TBLORG Insert operation...When some exception is occured then I rollback all the data..if not then insert statements are commited..
STEP II :->
On table TBLORG one trigger is written..that will execute on each new insert...In this trigger I get the current record(Current employee) data from TBLEMP
Now my question is for executing trigger is it necessary to commit the TBLEMP operation, before getting data from TBLEMP.

This works perfectly when i create a table as deepa user. But say when another User creates a table in my schema
like create table deepa.test1 ( a number) This trigger is not fired. Whenever a table is created by me or by any other user in my Schema, i need the trigger to be fired.
