Access update cascade ref constraint question
Access allows the definition of update cascade referential
constraints. This type of constraint is not allowed to be
defined declaratively in Oracle, but can be implemented using
trigger code. Does the Access module in Migration Workbench
create the required triggers to enforce update cascade
relationships?
Thanks,
George

Well, there is no UPDATE CASCADE clause supported in Oracle.

You can refer to following link from Tom Kyte as to how you can implement the UPDATE CASCADE.

APEX DB: Not accepting the constraint ON UPDATE CASCADE
Hi
My schema tables is not accepting the ON UPDATE CASCADE constraint as it was accepting the ON DELETE CASCADE constraint. My use case is to update the records in the child tables, when a PK of parent table is modified/updated. Please help.
Thanks
BhaveshBavesh,
Boy this question could spark a huge debate about relational theory and the merits of allowing the update of a primary key... But instead of stirring the pot, I'll answer your question. :-)
Unfortunately Oracle does not support the ON UPDATE CASCADE constraint that PostgreSQL and other databases do.
You might look at [this discussion|http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:5773459616034] on ASK TOM where he talks about the merits and references a couple ways you can achieve similar things in Oracle.
Hope That Helps,

hi all
I posted the same question inn this forum but did not get any answer i'll try again in this post
my problem is that i created my tables in the database without on delete cascade on the foreign constraint and now 'm trying to modify that
I dropped the old foreign constraint and created new one with "on delete cascade" this worked fine for one table but when i came to the other tables it gave me this error:
ORA-02443:cannot drop constraint - constraint unavailable
but I'm sure the constraint with the name i used is available !!!
what are your suggestions???
another problem:

select constraint_type,constraint_name from user_constraints where table_name='<TABLE_NAME>' and

How do you access updates to apps from the App store after changing to a new ID because the password on the old ID was changed by the former husband and you don't know what it is now? And you set up your own new ID and account but can NOT access the updates, from the App store for the many apps that you already have, because they require that you sign in with that former now inaccessible ID and account and password? Call it a problem of modern times and changing relationships, if you want to be charitable.
So I guess it will only be new apps that I download that are allowed to give me their updates while 13 updates wait for me on an ID I can no longer access.
Yes... sorry.
In the future, if need be, you can re download your purchases for free > Downloading past purchases from the App Store, iBookstore, and iTunes Store
Good rule of thumb is to back up your purchases regardless > Mac App Store: Backing up your app purchases -
It's possible ON UPDATE CASCADE in table relationships?
Hi, how are you?
Sorry my weak English, I'm brazilian.
I like create an "ON UPDATE CASCADE" in my table relationship but find only "ON DELETE CASCADE" in Oracle 9i Database Online Documentation.
I would like your help.
Thank you.

Team T.I.
www.coodetec.com.brTom Kyte wrote a package for this:
UPDATE CASCADE PACKAGE
Generates needed package and triggers to support update cascade in Oracle without removing or infringing on DECLARITIVE RI.
This package supports:
- Tables with multi-part primary keys (primary key(a,c,b))
- Update cascade to many child tables from one parent
- Self-referencing integrity such as that found in the SCOTT.EMP table (mgr->empno)
- Is completely application transparent. The application does not know it is happening
- Versions 7.0 and above of the database.
- Tuned and optimized to fully avoid full table scans on all tables (complete with utility to show you un-indexed foreign keys in a schema, Cascading an update to un-indexed foreign keys can be bad). -
ON UPDATE CASCADE and Autoincrement primary key with Oracle SQL Developer
hello everybody,
I want to know if Oracle SQL Developer manage autoincrement on primary key and "ON UPDATE CASCADE" when i migrate (with data) SQL Server database in Oracle database.

How to access/update Routing Rules in WorklistApplication console ?

How to find last accessed/updated tables and the query text?
I am using :
Oracle8i Enterprise Edition Release 8.1.7.4.0 - Production
With the Partitioning option
JServer Release 8.1.7.4.0 - Production
How to find last accessed/updated tables and the query text?
Regards
LEE1212Check DBA_TBALES view there you find one date column that indicate last update
One option is as follows:
(1) Turn the auditing on: AUDIT_TRAIL = true in init.ora
(2) Restart the instance if its running.
(3) Audit the table:
AUDIT INSERT,SELECT,DELETE,UPDATE on TableName
by ACCESS WHENEVER SUCCESSFUL
(4) Get the desired information using :
SELECT OBJ_NAME,ACTION_NAME ,to_char(timestamp,'dd/mm/yyyy , HH:MM:SS')
from sys.dba_audit_object.

Hi
I have a navigation list on my view...and ONSELECT of a particular item in the list i have written the below code
DATA lo_componentcontroller TYPE REF TO ig_componentcontroller.
DATA ls_navi_list TYPE wd_this->element_NAVI_LIST.
data CONTEXT_ELEMENT TYPE REF TO IF_WD_CONTEXT_ELEMENT.
Get key information for selected navigation list entry
break-point.
context_element->get_static_attributes(
IMPORTING
static_attributes = ls_navi_list ).
how ever i am getting the error "cannot access null obj ref " at
context_element->get_static_attributes(
IMPORTING
static_attributes = ls_navi_list ).Oooohhh! Now I got the problem!
The problem is that inside the function, you have an if clause, that when the SWF loads an amount of bytes, you send it to the frame four. The problem occurs because even you sending it to fame four, it is still listening to the PROGRESS_EVENT, when this events is dispatched the method is called again, trying to set the label to the textfield that does not exists anymore.
To resolve it, just add a removeListener before send it to frame 4.
function PL_LOADING(event:ProgressEvent):void {
if (event.bytesLoaded>=3704635) {
this.loaderInfo.removeEventListener( ProgressEvent.PROGRESS, PL_LOADING );
this.gotoAndStop(4);
if (this.loaderInfo.bytesLoaded >= this.loaderInfo.bytesTotal) {
this.loaderInfo.removeEventListener( ProgressEvent.PROGRESS, PL_LOADING );
this.gotoAndStop(4);
This will fix the problem.
