One trigger for Multiple tables
Hi all,
I want write a trigger for mutiple tables.
For Example,
In database schema,some user update one table.I want to capture what the table and capture old value and new value.
the above example for all insert and delete also.
Regards
Fame
Hi, Fame,
Sorry, a trigger only works on one table, so you need a separate trigger on each separate table.
All of those triggers can call a common procedure.
If you'd like to give a more detailed description of what you want to do, using two or three tables, then someone can give you more detailed instructions on how to do it.
Always say which version of Oracle you're using.

Hey,
I'm Pretty new to Access, as I've been given units to cover for my college course. Unfortunately my tutor has had this dumped on him too (so he's kinda self teaching as he goes as well)....
My issue is that I am trying to create a single form that will allow for all the information to be entered onto, which will then disseminate that info to the separate tables.
The database is a simple film database that has 8 tables in total. Seven are data tables (Filminfo; Certificate; Genre; Series; Role; Producer; Actor) and the seventh is a central table that is filled with keys as a connection for them all. Series is also
an off shoot from the filminfo table. I do have a pic, but I couldn't attach an image until my account was verified!
This is how we were advised to set it out and as far as I can tell the other parts that have been built are working. I know there is a way to do it, but tonight the internet is failing me, that, or my lack of understanding
exactly what I'm reading.
Therefore any help that could be offered by anybody that can work out what I'm rambling on about, would be most appreciated (even more so if in layman's terms)What you have in relational database terms is a 7-way many-to-many relationship type between the 'referenced' tables. This is what your eighth table is modelling by resolving the many-to-many relationship type into seven one-to-many relationship types.
The problem here is that you are going to end up with a huge amount of 'redundancy' in the table modelling the relationship type. At least some of the other tables represent entity types of which there can be more that one instance per film, e.g. there
will be more than one actor in most films. So let's say you record four actors for a film. That means four rows in the table, but you then have to record the producer of the film four times as well, entering the same foreign key value into all
four rows. That's what's meant by redundancy. Redundancy is a bad thing because it leaves the table open to the risk of 'update anomalies', e.g. two or more different producers could be inadvertently entered in different rows of the four.
Which is the correct one? There's no way of knowing.
So what relationship types do we really have here? Let's concentrate on films and actors. Each film can have many actors, and each actor can appear in many films (think Michael Caine!), so the relationship type is many-to-many. Now a many-to-many
relationship type cannot be modelled directly between two tables, it's done by a third table which resolves it into two one-to-many relationship types. So in broad outline the tables would be like this:
Films
....FilmID (PK)
....Title
....ReleaseDate
....etc
Actors
....ActorID (PK)
....FirstName
....LastName
....etc
and to model the relationship type:
FilmActors
....FilmID (FK)
....ActorID (FK)
....Role
The primary key of this last table is a composite one made up of the two foreign keys FilmID and ActorID.
Karl's already given you a clue how to represent this; by means of a form/subform. The form would be based on Films and the subform on FilmActors. For a simple example of this basic type of many-to-many relationship type and how to represent it
in a form/subform take a look at StuidentCourses.zip in my public databases folder at:
https://onedrive.live.com/?cid=44CC60D7FEA42912&id=44CC60D7FEA42912!169
If you have difficulty opening the link copy its text (NB, not the link location) and paste it into your browser's address bar.
This little demo file illustrates a number of interfaces using forms, but just look at the conventional form/subform set-up. The other two are just there because from time to time people have asked how to do it in these other ways. Quite why they
want to is another matter!
My demo just has one subform, but there's no reason why you can't have multiple subforms in a films form of course, each for a different related entity type, each linked to the parent form on FilmID. Tip: to save space put ach subform on a separate
page of a tab control, with the main film data in the parent form above the tab control so it's visible permanently as you move between different pages of the tab control.
BTW in my StudentCourses demo try typing into the combo box in the subform the name of a new course not currently listed, French say, and see what happens. Take a look at the code in the combo box's NotInList event procedure to see how it works.
For other uses of this event procedure take a look at the NotInlist demo file in the same OneDrive folder.
I can sympathise with your tutor BTW. My next door neighbour is head of the art department at a high school, but she has to teach maths also!
PS: I included Role as column in the FilmActors table, but what about Alec Guinness in Kind Hearts and Coronets? (google it if you're not familiar with the film) How do you think you'd handle that situation?

One sequence for multiple lookup tables?

Hello,
I need some help rewriting a trigger, the data structure changed for one of our tables and now my trigger is invalid. I know that we can't have a trigger on multiple tables but I was hoping that someone could give me some ideas.
Trigger:
create or replace
TRIGGER
"CMKAT"."USER_STATUS_CHANGE"
Before update on WOB
For each row
Declare
Catalog_name varchar2(40);
Variant_name varchar2(40);
Wp varchar2(10);
Old_status varchar2(40);
New_status varchar2(40);
Begin
If (:old.wobstakeys <> :new.wobstakeys) Then
Select katbezc into catalog_name from kat where katkeyi = *:new.dokkatkeyi;* - COLUMN BELONGS TO DOK TABLE
Select kvtbezc into variant_name from kvt,kav where kvtkeyi=kavkvtkeyi and kavkeyi = :new.wobvarkeyi;
Wp := *:new.doksnei || '-' || :new.doksnli*;* - COLUMNS BELONG TO DOK TABLE
Select stabezc into old_status from sta where stakeys = :old.wobstakeys;
Select stabezc into new_status from sta where stakeys = :new.wobstakeys;
Insert into status_log values (catalog_name, variant_name, wp,old_status, new_status);
End if;
End;
Of course I get errors when I attempt to compile .....
bad bind variable :new.DOKKATKEYI
bad bind variable :new.doksnei
bad bind variable :new.doksnli
Any help would be great ... Thank you!
Edited by: user10448714 on Aug 18, 2009 12:45 PMHi,
It sounds like you need to SELECT some values from the dok table into local variables. You can then use those local variables in SQL statements:
Select katbezc
into catalog_name
from kat
where katkeyi = new_dokkatkeyi; -- new_dokkatkeyi is a local variableor PL/SQL statements:
Wp := new_doksnei
|| '-'
|| new_doksnli;If you need help, post
an "UPDATE wob ..." statement
the existing row in wob,
any relevant data from any other tables, and
what the UPDATEd row should be when everything is over.
Please don't post unformatted code.
Add white space to make the code more readable.
When posting formatted text on this site, type these 6 characters:
{code}
(small letters only, inside curly brackets) before and after sections of formatted text, to preserve spacing. -
Single Trigger for muliple tables
Hi All,
I have one requirement to create a trigger to populate a table (X) based on the any insert or update on few tables (A,B,C,D,E,F).
Do I need to create trigger for each table ??. any idea of using all tables in one trigger.Hi,
this is not possible.
but you can use multiple trigger on single table
if you can use view, then you can use INSTEAD OF Trigger on view
for example
CREATE OR REPLACE VIEW manager_info AS
SELECT e.ename, e.empno, d.dept_type, d.deptno, p.prj_level,
p.projno
FROM Emp_tab e, Dept_tab d, Project_tab p
WHERE e.empno = d.mgr_no
AND d.deptno = p.resp_dept;
CREATE OR REPLACE TRIGGER manager_info_insert
INSTEAD OF INSERT ON manager_info
REFERENCING NEW AS n -- new manager information
FOR EACH ROW
DECLARE
rowcnt number;
BEGIN
SELECT COUNT(*) INTO rowcnt FROM Emp_tab WHERE empno = :n.empno;
IF rowcnt = 0 THEN
INSERT INTO Emp_tab (empno,ename) VALUES (:n.empno, :n.ename);
ELSE
UPDATE Emp_tab SET Emp_tab.ename = :n.ename
WHERE Emp_tab.empno = :n.empno;
END IF;
SELECT COUNT(*) INTO rowcnt FROM Dept_tab WHERE deptno = :n.deptno;
IF rowcnt = 0 THEN
INSERT INTO Dept_tab (deptno, dept_type)
VALUES(:n.deptno, :n.dept_type);
ELSE
UPDATE Dept_tab SET Dept_tab.dept_type = :n.dept_type
WHERE Dept_tab.deptno = :n.deptno;
END IF;
SELECT COUNT(*) INTO rowcnt FROM Project_tab
WHERE Project_tab.projno = :n.projno;
IF rowcnt = 0 THEN
INSERT INTO Project_tab (projno, prj_level)
VALUES(:n.projno, :n.prj_level);
ELSE
UPDATE Project_tab SET Project_tab.prj_level = :n.prj_level
WHERE Project_tab.projno = :n.projno;
END IF;

[ADF Help] How to create a view for multiple tables
Hi,
I am using Jdeveloper 11G and ADF framework, and trying to create a view to update multiple tables.
ex:
Table A has these fields: ID, Name
Table B has these fields: ID, Address
A.ID and B.ID are primary keys.
B.ID has FK relationship with A.ID
(basically, these tables have one-to-one relation)
I want to create a view object, which contains these fields: B.ID (or A.ID), A.Name, B.Address.
So I can execute C,R,U,D for both tables.
I create these tables in DB, and create entity objects for these tables.
So there are 2 entity objects and 1 association.
Then I create a view object based on B and add fields of A into the view:
If the association is not a "Composition Association",
when I run the model ("Oracle Business Component Browser") and try to insert new data, fields of A can't edit.
If the association is a "Composition Association", and click the insert button, I will get
"oracle.jbo.InvalidOwnerException: JBO-25030: Failed to find or invalidate owning entity"
If I create a view object based on A and add filed of B into the view:
When I run the model and try to insert new data, fields of B can't edit, no matter the association is or is not a composition association.
So... how can I create a view for multiple tables correctly?
Thanks for any advices!
Here are some pictures about my problem, if there is any unclear point, please let me know.
http://leonjava.blogspot.com/2009_10_01_archive.html
(A is Prod, B is CpuSocket)
Edited by: user8093176 on Oct 25, 2009 12:29 AMHi Branislav,
Thanks, but the result is same ....
In the step 2 of creating view object, I can select entity objects to be added in to the view.
If I select A first, and then select B (the "Source Usage" of B is A), then finishing the wizards.
When I try to create a new record in the view, I can't edit any properties of B (those files are disabled).
If I select B first, and then select A in crating view object, the result is similar ...
Thanks for any further suggestion.

Can we use single DB Adapter for multiple tables
Hi,
I have 3 tables. ONE is the Master table and other 2 tables having Primary and foreign key relationships with the Master Table.
Data is enter in the Tables 2 & 3 (based on Master Table Primary key)
I have to use a DB Adapter in BPEL Process which will be in Transaction (what type of Transaction is Best in such a Scenario).
- How do i implement it in BPEL.
- Can i use a Single DB Adapter for Multiple Tables ? (*Views* should not be created for tables 1, 2 & 3),
as we want to avoid using multiple DB Adapters, as in future Tables may increase or decrease...
- while in Transaction if Table 2 fails in Inserting / Updating, it should roll back on error and also if Table 3 fails in Inserting / Updating, it should roll back table 2 and Table 3.
- how access to concurrent users is maintained / managed in such a scenarios.
But everything should be done using Single DB Adapter without creating a separate view.
Is this Possible in BPEL..
If not, How do we design, Implementation such a BPEL Process in Transaction with a best in Performance (both BPEL Process & DB Resources)
thanks in advance
thanks & regards,
anvv sharmaHi,
Thanks for your quick response.
I have few quires.
If we use PL/SQL, how do we implement transaction and Exception Handling appropriately based on the Error / Exception in BPEL.
If the Table 2 or Table 3 gives out Error / Exception, i have to handle it separately and intimate accordingly.
Suppose, if Table 2 got Error / Exception - Error Handling would be 'Roll back due to error in Table2'
Thanks & regads, -
User Datastore for multiple tables and columns!
Hi,
I hop so much, someone can help me.
I've made a user datastore to index multiple columns of multiple tables.
Now, the Documentation of Oracle explains the idexing of one table.
I have multiple tables, which have all, the columns descr and tagnr. I want to make a query sth like this:

Any Help would be appriciated!!
Kind Regards,
ArsinehArsineh,
I realise that it has been quite some time since you posted this question but I thought I'd reply just in case you never did manage to get your user datastore working.
The reason your procedure will not work is simple. A user datastore procedure accepts a rowid input parameter. The rowid is the ID of the row that Oracle Text is currently trying to index. In the example you have given, you are attempting to use the supplied rowid as the primary key for multiple tables, this will simply never work as the rowid's across multiple tables will never correspond.
The best way to achieve your goal is to create the index on a master table which contains the common primary keys for each of your four tables e.g.
MASTER_TABLE
COL:COMMON_KEY (NUMBER(n))
COL:USER_INDEX_COLUMN (VARCHAR2(1))
If you create the user datastore index on the MASTER_TABLE.USER_UNDEX_COLUMN column your stored proc simply needs to read the correct row from the MASTER_TABLE (SELECT t.common_key into v_CommonKey FROM master_table t WHERE t.rowid = rid) and issue subsequent queries to extract the relavant data from the t1..t4 tables using the common key e.g.
SELECT t1.tagnr, t1.descr into v_tagnr, v_descr FROM t1 WHERE t1.[PRIMARY_KEY_FIELD] = v_CommonKey;
SELECT t2.tagnr, t2.descr into v_tagnr, v_descr FROM t2 WHERE t2.[PRIMARY_KEY_FIELD] = v_CommonKey;
and so on...
Hope this helps

Creation of sequence and trigger for each table!!!!!!!1
Hi
I am new to trigger and Sequence field. In one of my database we have many tables with fields for specifing ID numbers. Iam planning to insert the ID field with help of a Sequence and trigger...that trigger fires by adding the sequence value from the dual table. Now the point is here we r having around *60* table with ID field. And i am planning use the above process for each table by creating sequences and trigger for each table.
Will this affects the performance of database.
Is there any other option other than the above process, I mean other than creating sequences and trigger for each table.

One TPV for multiple Countries
Hi Experts,
Could you pls share experirnce/knowledge around having one TPV for multiple countries together. The scenario is like below:
1. There are mutiple Countries in Central America which are small islands for whom we need to roll out the Travel and Expense Solution.
2. The Company code is only one which contains employees from all these Countries.
Could you tell us how can we do the setup. Should we create one TPV at the company code level. OR should we rather use some other criteria for selecting the TPV maybe at the Personnel area or Personnel Sub Area level.
Your help is much appreciated.
Regards,
VijayHi Kiron,
These things I am aware about too. My real question is if I create only one TPV for the company code and assign the Country of the Company code then what issues would this cause. To name a few pls see below.
1) The domestic Country would always be the Company code Country so would be treated as Domestic Country and show on the Form also as domestic Country even for the employees who are from other Countries.
2) There are setting which SAP allows differently for Domestic and International like per diem, miles cumulations. So these necessarily have to be kept as same even though local laws are different in all these countries as Domestic is only the Company code Country.
So I need detailed analysis of what impact I will have by having only one TPV as against making many TPV like one for each Country by using some other parameter like Personnel area/Personnel sub area etc.
Appreciate your help!
