Updating A child Table As Administrator

Hello Eevryone, I read a post here http://forums.adobe.com/thread/463635. And i first off want to commend you guys on your awesome contribution to novices like me. I understand the technique presented here but I have a different problem though. I have two tables, which are related by one to many. Personals Table and Courses Table. One person can have many courses. Only the Admin can update and add new courses. The Courses Table has a Foreign key: personal_Id. The admin has a view page and can update personals table easily. How can I add and update courses for a selected Person. I mean how to build the recordset in Dreamweaver CS5 so that I cant pick just that persons ID and add all course just for his account. In the technical sense how do I parse the FK_personal_Id so that the add course form or update course form only stores the course for that personal_ID on Personal Table. Please I hope you understand how I have explained it but I would love to know this procedure. Thank you very much.

You don't really want to create a recordset to update the tables. You don't mention what scripting language you are using. In ASP, you CAN create updateable recordsets, but it's really not necessary in this circumstance. You simply need to create an update statement to update the parent table, and an insert statement to insert the record into the related table when the form is posted. You can use DW's server behaviors to accomplish one or the other if you want - but not both. If I am performing a CUD on multiple tables, I would think about writing a stored procedure. Again, it depends on your DBMS. I'd suggest looking into DW Insert record and update record server behaviors to start with.

Update data to upper case in parent/child tables

Hi Gurus!
In production we have a product table and which is being reference by many tables making it parent child relationship. By mistake, we realized that last month some product were added in lower case and now we got a request to update all these product codes to upper case so that the existing code that use these tables have no impact. Appreciate if you can give some idea on how can I update the existing data in the parent table to upper case along with the child records?
Regards
Sri

Are the product code that you need to update what is stored in the child tables? If so, then you would need to do it in several steps, something like:
Identify the child tables
SELECT table_name, constraint_name
FROM user_constraints
WHERE r_constraint_name = (SELECT constraint_name
 FROM user_constraints
 WHERE table_name = 'PRODUCT_TABLE' and
 constraint_type = 'P');Create the new upper case product code in product table:
INSERT INTO product_table
SELECT UPPER(product_code), other_columns
FROM product_table
WHERE product_code <> UPPER(product_code);Update the child tables to uppercase the product codes
UPDATE child1
SET product_code = UPPER(product_code)
WHERE product_code <> UPPER(product_code);finally, delete the lower case product codes from product_table
DELETE FROM product_table
WHERE product_code <> UPPER(product_code);John

Child Table Cache Problem - Only in Environment

Hi All,
I have master-child tables in a page. Master table is based on a VO and child table is based on pl/sql EO. When user updates any child table row and hits on save, I load the same page again by releasing AM. The problem is when the page loads again after update, two records are being shown in child table. One record with old value and other record with the modified value. But in database only record exists and it is successfully updated. If we again hit "Apply" on the page then only the updated record is shown. I am sure this is due to vo/eo caches. But after insert/update, I am forwarding to same page with retain am set to false. So this should clear-off all associated caches. I had even tried to clear vo caches explicitly before redirection. But even this doesnt help. This issue exists only in the environment but cannot be reproduced locally in JDev. Its working perfectly fine in JDev.
Any pointer on the above issue?
Thanks in advance,
Murari

hmm...caching may be happening at webbean level rather than the VO level. You can confirm this by getting the value of VO.getrowcount in processRequest.
For both Classical table as well as Advanced Table, clearcache() method is available to clear the cache of data object for inner table. Call this in processRequest. You can put in a check to call this only when you self-redirect to this page.

UPDATE of column in parent only UPDATEs first row in DENORMALIZED child table

In the Repositiry in Designer 6i, I denormalized DESC1 column to
pull the value of DESC1 in the parent table. The child table has
four (4) records with matching foreign keys. When I go into my
Form and update DESC1 in the parent, only the first of the four
child DESC1's are updated. Any ideas?
Thanks,
Dan

Dan,
Sorry, known bug, but should be fixed in next release.
Have a look via metalink at article <Note:156833.1> this
explains in detail the problem and a fix.

Cascade update of primary key in child tables

Hi,
We have a typical scenario in which the primary key has to propage to the child table into 3 levels. We are getting the no parent key exception if we create new data into the three tables using 3 level master detail relationship and execute commit operation. The following is the structure of the tables.
Parent_table (sno number primary key, name varchar2(100));
Child_table (fk_sno number primary key, name varchar2(100), foreign key (fk_sno) references parent_table(sno));
GrandChild_table (sno number primary key, fk_sno number, name varchar2(100), foreign key (fk_sno) references Child_table(fk_sno));
The requirement is to update fk_sno in child_table and grandchild_table with the trigger generated primary key sno in the parent_table.
The application module is having the following structure
parenttable
|
----------childtable
|
-----------grandchild_table
If we create new records into parent_table and child_table it is working fine when we commit the data. If we create another record into grandchild_table and commit data we are getting the foreign key violation exception. We are using composition in the association to update the modified values to refresh the data.
Is there any problem in the data model to use fk_sno as primary key and foreign key in child_table.
Thanks and Regards,
S R Prasad

Hmm, another example is CSKS, this logic was probably designed already in the 1980s...maybe it was seen beneficial to be able to select the currently valid record by using the primary key only (the first record where DATBI is larger than system date, not possible when DATAB is the key instead).
Maybe there are better explanations. Why do you need to know this, just curious?

Update column data to Upper Case in parent and child table

Hi ,
I am facing issue while updating column value to upper case in parent table and child table. How can i do that ?
when updating parent row:
ORA-02292: integrity constraint (XXXXXXXXXXXXXX_FK) violated - child record found
When updatng corresponding child row:
ORA-02291: integrity constraint (XXXXXXXXXXXXXXXX_FK) violated - parent key not found
how can i update on both the places ?
Regards,
AA

I am facing issue while updating column value to upper case in parent table and child table. How can i do that ?
Why do you need to do that?
That is just ONE of several questions you should answer before you start modifying your data.
1. What is your 4 digit Oracle version? (result of SELECT * FROM V$VERSION)
2. If both values are the same case what difference does it make what that case is?hen you don't need to alter your original data.
3. What is the source of the column values you are using now? If you change your data to upper case it will no longer be identical to the source data.
4. What is your plan for enforcing future values to be stored in UPPER case? Are you going to use a trigger? Have you written and tested such a trigger to see if it will even work the way you expect?
5. Why aren't you using a surrogate key instead of a 'business' data item? You have just demonstrated one reason why surrogate keys can be useful: their actual value is NOT important.
You should reexamine your problem and architecture and consider other alternatives.
One alternative is to add a new 'surrogate key' column to use as the primary key. Just create a new sequence and use a trigger to populate the new column. Your current plans will require a trigger to perform the case conversion so instead of the just use the trigger to provide the value.
If the change is being done to facilitate searching you could just add a VIRTUAL column UPPER_MY_COLUMN and index that instead. Then you could search on that new virtual column and the data values would still be identical to the original data source.

Update key in parent and child tables

Situation:
Parent table (p) has a PK, p.parent_id. Child table (c) has a FK c.parent_id which, of course, points back to PK, p.parent_id.
I need to UPDATE the key in both tables but I am concerned about throwing a FK constraint violation. How does one get around this? Does one update the child first then the parent or vice versa? Seems either way a FK violation will occur...
thank u.

1) If you ever anticipate wanting to update a key, that key should not be the primary key of a table. Primary keys should be immutable. If this is going to happen with any regularity, you need to re-examine the underlying data model.
2) If the constraints were declared to be deferrable, you would simply mark them as deferred, update both tables, and commit (at which point the constraint would be validated). If the constraints were not declared to be deferrable, you will probably need to end up dropping and re-creating one or the other (presumably as a deferrable constraint this time).

How to update parent and child tables while updating parent table

I have a parent table EMPLOYEE which includes columns (sysid, serviceno,employeename...) sysid is Primary key, serviceno is Unique key and I have child table DEPENDENT includes columns (sysid,employee_sysid,name,dob...) here again SYSID is primary key for DEPENDENTS table, employee_sysid is Foreign key of EMPLOYEE table.
Now I want to change SYSID (using sequence) in EMPLOYEE table which need to be update in DEPENDENTS table as well
Note: I have 10000 records in EMPLOYEE table as well as I have 5 more child tables which need to update new SYSID.
please help me

first disable the FOREIGN KEY Constraints.
you can update Parent as well as Child record also with help of trigger.
here i am giving you one examlpe..it may help u.
create table parent(id number primary key,name varchar2(100))
create table child_1(id number primary key,p_id number,dob date,
CONSTRAINT FK_id FOREIGN KEY (p_id) REFERENCES parent (ID))
create table child_2(id number primary key,p_id2 number,addr varchar2(1000),
CONSTRAINT FK_id2 FOREIGN KEY (p_id2) REFERENCES parent (ID))
insert some test data to parent and child tables.
alter table child_2 disable constraint FK_id2
alter table child_1 disable constraint FK_id2
CREATE OR REPLACE TRIGGER delete_child

BEGIN
UPDATE CHILD_1
SET P_ID=:NEW.ID
WHERE P_ID=:OLD.ID;
UPDATE CHILD_2
SET P_ID2 =:NEW.ID
WHERE P_ID2=:OLD.ID;
END;
then Upadte parent table primary key col and check the child tables.
then enable the constraints...

11g child table update locking

Hi,
I'm posting this question after searching on multiple places and trying to understand 11g locking mechanism.
I've a table TXN1 transaction and has FKs to 3 different tables Account, customer, country and currency. ALL FKs are indexed (bitmap). I am updating TXN1 of amount column about 10,000 rows. (SID 1) As expected, it has taken lock type 3 SX on TXN1. But it has taken on lock type 4 (share) on Account, customer and country. Committing every 10k rows.
At the same time sid 2 is inserting into another TXN2 table which has FK to the same dimensions account, customer and currency. Only FK on ac_id is bitmap indexed. The inserts have taken SX lock(type 3) on tXN2 table (expected). But it is trying to take SX type 3 lock on account, customer, currency tables. typ3 lock taken on CCY but waiting on CST. But It is blocked by sid 1. It has resulted into Enque-TM contention and resulted into anywhere 60-300 secs wait time..
I understand update/delete in parent table results into locking of SX of child tables and need the FKs to be indexed to avoid etc. I didn't understand the following and appreciate if someone can help me.
1. Why is SID1 taking shared lock on the parent tables Account,customer,country and currency tables? The update statement is not updating any of those FK columns nor referring them in where clause(if it matters!). Is it to ensure that the parent rows are not deleted?
2. Why is SID2 taking SX lock on the dimension tables? Why is it not taking RS lock type 2 on parent rows? Why is SID1 taking shared lock type 4, but not 2?
Thanks
Ram

Update child table

create table p (p1 number constraint ppk primary key);
create table f (f1 number constraint ffk references p);
create trigger pt after update on p for each row begin
update f set f1 = :new.p1 where f1 = :old.p1;
end;
insert into p values(1);
insert into p values(2);
insert into p values(3);
insert into f values(1);
insert into f values(2);
insert into f values(3);
commit;
After this when I execute
update p set p1 = p1+1;
I am seeing all the records updated 4 in table f.This is because of the fact that above dml updates multiple rows at once.
My doubt: Is there any way to track which foreign key values have already been updated? Using that suggested way I would like to modify the trigger such that no row is updated twice.
Thanks in advance.

Please find the code which I have tried for the
same...
DROP TABLE f;
DROP TABLE p;
CREATE TABLE p (p1 NUMBER CONSTRAINT ppk PRIMARY
KEY);
CREATE TABLE f (f1 NUMBER CONSTRAINT ffk REFERENCES
p);
INSERT INTO p VALUES(1);
INSERT INTO p VALUES(2);
INSERT INTO p VALUES(3);
INSERT INTO f VALUES(1);
INSERT INTO f VALUES(2);
INSERT INTO f VALUES(3);
DROP TABLE a;
CREATE TABLE a(arowid ROWID);
DROP PACKAGE pkg;
CREATE OR REPLACE PACKAGE pkg IS
frowid ROWID;
END;
CREATE OR REPLACE PROCEDURE load(r ROWID) IS
     v NUMBER(1) :=0;
BEGIN
     SELECT 1
     INTO v
     FROM a
     WHERE arowid=r;
     IF(v=0) THEN
          INSERT INTO a VALUES(r);
          pkg.frowid:=r;
     ELSE
          DBMS_OUTPUT.PUT_LINE(r||' is already updated.');
     END IF;
END;
CREATE TRIGGER ft AFTER UPDATE ON f FOR EACH ROW
BEGIN
     load(:OLD.ROWID);
END;
CREATE TRIGGER pt AFTER UPDATE ON p FOR EACH ROW
BEGIN
     UPDATE     f
     SET      f1 = :NEW.p1
     WHERE      f1 = :OLD.p1
     AND      f.ROWID=pkg.frowid;
END;
SQL> update p set p1=p1+1;
update p set p1=p1+1
ERROR at line 1:
ORA-02292: integrity constraint (BI_LEARN.FFK)
violated - child record found
SQL>
Could anyone help me for this.
Thanks in AdvanceThe first logical error is here
     AND      f.ROWID=pkg.frowid;pkg,rowid to this point of time never corresponds to ROWID of table f.
That's why UPDATE in trigger doesn't run and also other actions respectively.
BTW: here
CREATE OR REPLACE PROCEDURE load(r ROWID) IS
     v NUMBER(1) :=0;
BEGIN
     SELECT 1
     INTO v
     FROM a
     WHERE arowid=r;
     IF(v=0) THEN
          INSERT INTO a VALUES(r);
          pkg.frowid:=r;
     ELSE
          DBMS_OUTPUT.PUT_LINE(r||' is already updated.');
     END IF;
END;You get an exception NO_DATA_FOUND, if You haven't a record in table.
Your branch starting with IF v=0 will be never processed ...

Parent-Child Table Update via Single Stored Procedure

Uses: Oracle 9i Server via a Remote Connection with restriction, Oracle 9i client, .NET 2.0+System.Data.Oracle namespace, Delphi+BDE;
I have an entry form which consists of a parent and a child table. I'm so keen in knowing whether there is any possibilities of updating the records via a single stored procedure? I mean if parent have a single record and corresponding to it, child have few records (more than 1 rows). I need to take the parent's value and child's value send it to the stored procedure and update it.
Regards,

The entry form gets the raw data from the user. So yes the data is captured front end but not updated nor processed. Once the user clicks "Save" or what ever the values are taken to the SP. In the SP the operations are done either as update or insert. Lets concentrate on Inserts only at the moment.
I.e. there are 2 tables as:
tbl_Payment(_PaymentID_, PaymentMode,PaymentDate, TotalPaymentValue);
tbl_PaymentAccount(_PaymentID,AccountID_,PaymentValue);
So the form has a top part which is bounded to the Parent Table which is "tbl_Payment" to few text boxes, and below it has a Datagrid, bounded to Child Table which is "tbl_PaymentAccount". And assume the the Single Stored Procedure as "sp_payment_addchg".
I can pass newly entered values to the SP as:
Command.Text = "sp_payment_addchg";
/*so all the parent table bounded values are updated as*/
Command.Parameter[0].value = text1.text;
Command.Parameter[1].value = text2.text;
and so on
Since the DataGrid may have multiple rows, I cant figure it out how to get those rows into a single parameter.
Regards,

Hello Gurus..... ISSUE with child Table update

I have an issue with child table update
I have created a GTC with one parent table and two child tables. I'm able to update the parent table and the values are found in db, but the ISSUE is the child Table values are not updating the db.
please give me a solution

Srikanth

If you are keeping referential integrity in the database, not in the application, it is easy to find the child and parent tables. Here is a quick and dirty query. You can join this to dba_cons_columns to find out on which columns the referential constraints are defined. This lists all child-parent table including SYS and SYSTEM users. You can run this for specific users of course.
select cons1.owner child_owner,cons1.table_name child_table,
cons2.owner parent_owner,cons2.table_name parent_table
from dba_constraints cons1,dba_constraints cons2
where cons1.constraint_type='R'
and cons1.r_constraint_name=cons2.constraint_name;

Master Child tables how to get the latest rows from both

Hi,
Need some help with the sql. I have two tables Master & Child. In my Master table I have multiple rows for the same record and in the child table also multiple rows for the same master row how can I get the latest one's from both.
For example Data in my Master table looks like
CONT_ID                  SEQ_NUM        DESCRIPTION
1                         189             Update 2
1                         188             Update 1
1                         187              NewNow in the child table for the same CONT_ID I may have the following rows
CONT_ID                   UPDATED_DATE                                     STATUS
1                        3/16/2010 2:19:01.552700 PM                          P
1                        3/16/2010 12:29:01.552700 PM                         A
1                        3/16/2010 12:29:01.552700 PM                         P
1                        3/16/2010 12:19:01.552700 PM                         NIn my final query how can I get the row with seq_num 189 as it's the latest in Master table and from child table the row with status of P as it's the latest one based on the time. Here is the query i have but it returns the latest row from the child table only and basically repeats the master table rows as opposed to one row that is latest from both:
Thanks

Hi,
You can use the analytic ROW_NUMKBER function to find the latest row for each cont_id in each table:
WITH     got_m_rnum     AS
     SELECT     cont_id,     seq_num,     description
     ,     ROW_NUMBER () OVER ( PARTITION BY cont_id
                               ORDER BY         seq_num     DESC
                       ) AS m_rnum
     FROM    master_table
--     WHERE     ...     -- any filtering goes here
,     got_c_rnum     AS
     SELECT     cont_id, updated_date,     status
     ,     ROW_NUMBER () OVER ( PARTITION BY cont_id
                               ORDER BY         updated_date     DESC
                       ) AS c_rnum
     FROM    child_table
--     WHERE     ...     -- any filtering goes here
SELECT     m.cont_id,     m.seq_num,     m.description
,     c.updated_date,     c.status
FROM     got_m_rnum     m
JOIN     got_c_rnum     c     ON     m.cont_id     = c.cont_id
                    AND     m.m_rnum     = c.c_rnum
                    AND     m.m_rnum     = 1
;If you'd like to post CREATE TABLE and INSERT statements for the sample data, then I could test this.
If there happens to be a tie for the latest row (say, there are only two rows in the child_table with a certain cont_id, and both have exactly the same updated_date), then this query will arbitrarily choose one of them as the latest.

How to find the level of each child table in a relational model?

Earthlings,
I need your help and I know that, 'yes, we can change'. Change this thread to a answered question.
So: How to find the level of each child table in a relational model?
I have a relacional database (9.2), all right?!
 O /* This is a child who makes N references to each of the follow N parent tables (here: three), and so on. */
 /↑\ Fks
 O"O O" <-- level 2 for first table (circle)
/↑\ Fks
"o"o"o" <-- level 1 for middle table (circle)
 ↑ Fk
"º"Tips:
- each circle represents a table;
- red tables no have foreign key
- the table in first line of tree, for example, has level 3, but when 3 becomes N? How much is N? This's the question.
I started thinking about the following:
First I have to know how to take the children:
select distinct child.table_name child
from all_cons_columns father
join all_cons_columns child
using (owner, position)
join (select child.owner,
 child.constraint_name fk,
 child.table_name child,
 child.r_constraint_name pk,
 father.table_name father
 from all_constraints father, all_constraints child
 where child.r_owner = father.owner
 and child.r_constraint_name = father.constraint_name
 and father.constraint_type in ('P', 'U')
 and child.constraint_type = 'R'
 and child.owner = 'OWNER') aux
using (owner)
where child.constraint_name = aux.fk
 and child.table_name = aux.child
 and father.constraint_name = aux.pk
 and father.table_name = aux.father;Thinking...
Let's Share!
My thanks in advance,
Philips

Justin,
Understood.
Nocycle not work in 9.2 and, even that would work, would not be appropriate.
With your help, I decided a much simpler way (but there is still a small problem, IN RED):
