Issues while changing primary key in table

Hi
I have one table. In that two fields are primary key. I want to change the second PK as FK only. But when i am changing this field as FK. Its showing one error 'Primary Key Change not permitted for value Table ZCAUSECATMASTER' . How to avoid this error.
Please help me.

Hi.....
Remove that primary key for the second field and assign your foregin key..table to that filed.....
So when you give entries in that second filed it will be validated with its foregin key table......its nothing but check table...
what all values in the foregin table only can given.....

ORA-02266: unique/primary keys in table referenced by enabled foreign keys

Hi,
I am trying to delete data from a table by dropping a partition. I have identified all the child tables by running the following command.
select 'select count(*) from '||table_name||' where employee_id = 100;'
from dba_constraints
where constraint_type='R'
and r_constraint_name in
(select constraint_name from dba_constraints
where constraint_type in ('P','U') and table_name='EMPLOYEE);
'SELECTCOUNT(*)FROM'||TABLE_NAME||'WHEREEMPLOYEE_ID_ID=100;'
select count(*) from PT_ORDERS where employee_id = 100;
select count(*) from PT_DEP where employee_id = 100;
select count(*) from PT_SKILLSET where employee_id = 100;
I dropped the partition for employee_id 100 in all of the child tables. The select count(*) returns 0 rows for each of the above.
When I try to run the below command on the EMPLOYEE table, I get 'ORA-02266: unique/primary keys in table referenced by enabled foreign keys'.
alter table EMPLOYEE drop partition EMP_ID_100;
I cant see why I am unable to drop this partition now as there is now child data in any of the referenced tables. Any suggestions or help on this would be greatly appreciated.
Thanks.
Rgs,
Rob

You should disable foreign key constraints first and drop partition. Deletion of rows or dropping partitions in childs don't work in this case
as you have the global dependency:

I guess you should consider such option as Referencial partitioning (with some restrictions).

Add a primary key to table.

Hello everybody,
I want to add a primary key to a table but it doesn't work.
select count(*), count(id) from tableA;
COUNT(*) COUNT(ID)
830447 830447
You see: The number of ids is equal to the number of rows. The ID is not marked as unique but it should be unique. I try to set id as the primary key:
alter table tableA add constraint "pk_constraint" PRIMARY KEY (id);
But I a get an error message: ORA-02437: cannot validate (pk_constraint) - primary key violated.
What is the problem?
I use Oracle 11g.

I use Oracle 11g.Revisit your query... 11g can help much in this sql.... select count(*), count(id) from tableA;... to get what your desired output should be.

Populate choice component with 2 primary key in table

There are 2 primary key in table. When I create my uix with jheadstart, the UIXs don't populate choice component. How can I create automatically populate choice component, with 2 PK in table?

A choice component can only have one value attribute. So if you have a composite primary key in the table you use to populate the choice, it will not work correctly, because based on this single attribute the choice cannot render the correct row as selected.

Inner join-select -primary key in table issue

Hi ,
Iam using FEBKO(header) and FEBEP(item) in inner join select .But the datas fetching by this selct in not correct.The analysis is the is no common primary fields in the both table.
Question 1-> Can i use inner join without common primary key in the both tables, weather it possible to make a select without common primary key in both table. Please kindly let me know.
Question 2-> What is the other possible way to give the selct for both table(better performance)
Regards,
Veera

Hi,
When you use INNER JOIN in this case, link your tables based on KUKEY and ESNUM fields, bcoz there can be many items under a single header. So this will work for you, even from the performance point of view.
Hope this is helpful to you. If you need further information, revert back.

How to create tabular form whithout primary key in table

Hi All,
I have requirement to create a tabular form but the problem is, the table which I am using in the application don't have any Primary key, I am using only one table can't change any thing in table.(i.e can't add any row in table,no change in data model)
How can I create tabular form when primary key is not available.
looking forward for all of your quick responce.
Thanks in advance.
Dikshit Kumar Nidhi

You can create a view like
select a.rowid id, a.*
from table a
and create a tabular form on this view. You can use
the new column ID as Primary key.Did you try to actually do this? I did at
http://htmldb.oracle.com/pls/otn/f?p=24317:159
And when I change something and click Submit, I get an error
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-01733: virtual column not allowed here, update "VIKASA"."NO_PK_VW" set "ID" = :b1, "I" = :b2, "J" = :b3 where "ID" = :p_pk_col
Thanks

Change primary key in ztable

Hello everyone
I need some advice.
I have transp. table ZINVOICE which have data in production system.
field of table are
VBELN Primary key
KUNNR
NAME
FKART
FKDAT
NETWR
STAT
TAXINVNUM
ZFKDAT
ZNETWR
now i want table ZINVOICE have 2 primary (VBELN + TAXINVNUM)
when i activate system show
Key is already defined; field TAXINVNUM cannot be in the key
Message no. AD434
Diagnosis
When defining table fields, you added further key fields at the end after entering a block of key fields followed by a block of non-key fields.
All the key fields of a table must be in a block at the beginning of the table.
Procedure
All key fields in a table should be entered in a single block.
is it mean that primay key must be in beginning of the table ?
can i delete field in table ZINVOICE and insert field and change position of fields to
VBELN Primary key
TAXINVNUM Primary key
KUNNR
NAME
FKART
FKDAT
NETWR
STAT
ZFKDAT
ZNETWR
can i do like this ?
is it impact my existing data in SAP ?
please advice.

As you are adding a new key, you should not get problem with duplicate records.
You should create two transport requests and activate/transport the table twice.
- In the first request, change the order of fields in the database table, don't add primary key now, activate , if required adjust database table (should not be required), transport database table in target system.
- In the second request, declare the second field as a primary key, proceed same way.
DON'T TRANSPORT BOTH REQUESTS TOGETHER
First step
VBELN K
TAXINVNUM
KUNNR
NAME
Second step
VBELN K
TAXINVNUM K
KUNNR
NAME
Question: Did you forget to add the client field, if yes you will have to adjust the table and the records will be copied in every client, you will have to create and execute a small cleanup program
Third step
MANDT K
VBELN K
TAXINVNUM K
KUNNR
NAME

APEX 4.0 -Show and able to change Primary key values for Detail

In a Master-Detail form, is there anyway I can show and able to change/select my primary keys from a select list field? One of my primary keys on the Detail is also primary key from another table which restricts my values for this field. I was able to show the fields but I can not make changes to this field and save the changes. Is there anyway I can have both show the field and able to change field's value and save it? Please advice. Thank you very much for your help in advance.
-Grace

Yes AFAIK Apex (for better or worse) was designed such that the PKs are generated automatically with PL/SQL, by a trigger, or whatever other algorithm that isn't in the control of the end user. It also only seems to allow a composite PK of no more than two columns.
My usual strategy is to:
1. Define the PK as a number (some sort of RECORD_ID, RECORD_SEQ, whatever) and populate it via a trigger on-insert.
2. Define the "business" PK as a separate unique index. This way the user can set and modify it to their heart's content and it also isn't limited to just two columns (if the composite key's business requirement is such that more than two columns are needed).

JCA DB Adapter - merge - changing Primary Key

Hello,
I have an OSB business service that does a merge operation using a JCA DB Adapter. I recently changed the primary key of the table it's merging into, so also changed the toplink file of the business service (manually via sbconsole).
However, in certain conditions, I'm getting an ORA-00001 error (JCA-11616). i.e. the merge is trying to do an insert that the violates primary key of the table.
Should I have also made a change to something other than the business service? The table WSDL and XML don't mention the primary key as far as I can tell...
Any ideas?
Cheers

That is probably a database error. If you changed the primary key of the toplink file to be less restrictive than the compound key in the database, you could potentially get this error. You need to make sure you have the primary keys or unique constraint columns from the database in the toplink file. You can then add additional columns to the toplink file based on your business logic, but never remove a database primary key from the file because the service could try a invalid insert.

Changing primary key(s)

Is it possible to change the primary key of existing persistent objects at
runtime? (If yes, are references from other tables updated automatically?)
Regards
Achim

Hi,
AFAIK, Kodo JDO 3.0.1 doesn't support the JDO optional feature:
javax.jdo.option.ChangeApplicationIdentity
So assuming you are using Application Identity for your class then you won't
be able to change the fields that are part of the primary key.
Not sure if that's what you meant?
Cheers

Issue while accessing a SQL Server table over OTG

Hi,
I have been learning oracle for about 1.5 years and am just starting to learn some OTG pieces. I am wondering about an issue. The issue is:
"We need help with an issue we are having while accessing a SQL Server table over OTG. We are getting the following error message in Oracle :
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Oracle][ODBC SQL Server Driver]Unicode conversion failed {HY000}
The column it is failing on is "-----------" in the view --------------- in the SQL Server database pointed to by the Oracle DB Link ------------------- thats created in the Oracle instances ---- and -----.
This was working before, but is now failing, we suspect its due to new multi-byte data being added to the base table in the above column."
I took out the details and added ---- instead. I am wondering your guys thoughts on fixing this issue and helping me learn along the way. Thanks

Hi Mike,
Thanks for the response, here are the details:
1. What is the character set of the Oracle RDBMS being used. What is returned by -
select * from nls_database_parameters;
NLS_CHARACTERSET
AL32UTF8
NLS_NCHAR_CHARACTERSET
UTF8
We get SQL_Latin1_General_CP1_C1_AS and 1252 as Collation Property and Code Page
The datatype of the column in question in SQL Server is nvarchar(100).
When I do a describe on the SQL Server view ( desc CK_DATA_FOR_OPL@------- ), I get the error below;
ERROR: object CK_DATA_FOR_OPL does not exist
Select * from CK_DATA_FOR_OPL@------ where rownum =1 does get me a row.
create table tmp_tab as
Select * from CK_DATA_FOR_OPL@----- where rownum =1;
desc tmp_tab shows the datatype of the said column in the table created in Oracle as NVARCHAR2(150).
Not sure why a column defined with size 100 in SQL Server should come across as 150 when seen over OTG. We see something similar in DB2 tables we access over OTG as well.
