Urgent Check Constraint Error

hi
i have a check constraint on a table B mean Nvl(Quantity,0)>=0 but when i update a table from a trigger on insertion of another table A
with :New.Quantity -ive it gives check constraint error.
Please Note it does not turn the balance into negative for table B
second because im inserting in table A then :new.quantity reffers to table A values not the table B
why this constraint error appears.
any body suggest
thanks in advance

So you have a constraint on table B and then a trigger on table A attempts to update table B with a negative quantity which violates the constraint and it throws a constraint error.
That sounds right to me. What's the problem?

Displaying an error message coused by check constraint

Hi,
I'm trying to replace oracle error message by my own message.
Form report is throwing an expected error like :
'Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-02290: check constraint ...'
I used the plsql block to handle with that but it doesnt set the my message. After press a button the check constraint validate a date and if data are unexpected then throwing a error which i want to replace by my own.
The process is listed below:
DECLARE
invalid_sql EXCEPTION;
PRAGMA EXCEPTION_INIT (invalid_sql, -02290);
page_error EXCEPTION;
PRAGMA EXCEPTION_INIT (page_error, -20001);
BEGIN
:p12_error := NULL;
EXCEPTION
WHEN invalid_sql THEN
:p12_error := 'In case of sql injection attack some of the statements were forbidden: INSERT, UPDATE, DELETE, DROP, ALTER, TRUNCATE, EXECUTE';
WHEN page_error THEN
:P12_ERROR := 'Please contact your administrator !!!';
WHEN OTHERS THEN
:p12_error := SQLERRM;
END;
P12_ERROR -- hidden item
Then i set the 'success message ' :
&P12_ERROR.
What is wrong that is not showing my message?It not recognoze Init pragma?.
Please give my some points on it!

I followed Denes Kubick' way on his blog http://htmldb.oracle.com/pls/otn/f?p=31517:185:17139524101939:::RP,::
where he created process on SubmitThe process is a simple example of error handling in ApEx. It does inserting and at the
same time it handels exceptions. If an exception occurs, it will use a hidden item on the
page to store error messages. At the same time, the success message of that process
(which is what you get after pressing the "Save" button) is &P185_ERROR. item.
Returning to my previous post i got tabular form report where constraint makes error in case of writing 'insert, delete...' after save button where have been pressed. Pragma mechenism is trapping like you wrote exceptions.Ok.
So what i need configure to associate that process to trapped error?

Primary key and relevant not null check constraints....

Hi ,
There are some constraints of primary key type and not null check constraints on columns which constitute each primary key....
Should I/Do I have to drop them....????
Do they burden the db at the time of data validation....????
Thanks...

Hi,
>>There are some constraints of primary key type and not null check constraints on columns which constitute each primary key..
In fact, a column that constitutes a primary key, by default cannot accept NULL values. In this case, defines a PK column as NOT NULL would not be necessary.

I don't see any problem, otherwise, drop the NOT NULL constraint is the same with alter the column table like below:

Hi,
Well, are you trying to do a batch input on infotype 0000? If yes you need to check that the proposed values respects the time constraint, meaning no gap, no overlaps and no inversions. Also fields SUBTY, OBJPS, SPRPS and SEQNR must remain initial when processing IT0000...

How can I capture and re-present Oracle contraint/check/DML errors?

Hi,
New to APEX, I have a Designer/Web-PLSQL background.
In Designer I can define the messages that I want the user to see when check, constraint, etc. errors are generated by the application interaction with the database server (done through table API and the integration of the Designer generated screens).
In APEX, these types of errors all seem to show the default 'ORA' style message on an error page. How can I change these to 'human-readable' messages?
I'm obviously missing the trick that changes an ORA-0001 message referring to CUST_CODE_UK to something like 'This Code has already been assigned to another customer'? I want to use standard functionality, not really keen on creating my own DML packages for every table that needs to be accessed through a screen.

Is it possible to create a dynamic(with a select) check constraint?

create table a (col_to_be_coded_fora number);
create table b (col_to_be_coded_forb number);
create table c (col_name varchar2(20), col_code number, col_desc varchar2(20));
insert into c values ('col_to_be_coded_fora', 1, 'active');
insert into c values ('col_to_be_coded_fora', 2, 'de-active');
insert into c values ('col_to_be_coded_fora', 3, 'pending');
insert into c values ('col_to_be_coded_forb', 10, 'school');
insert into c values ('col_to_be_coded_forb', 20, 'hospital');
insert into a values ( 1); -- meaning 'active' for table a, column col_to_be_coded_fora, can go in
insert into a values (10); -- meaning nothing for table a, column col_to_be_coded_fora, must give error
insert into b values ( 1); -- meaning nothing for table b, column col_to_be_coded_forb, must give error
insert into b values (10); -- meaning 'school' for table b, column col_to_be_coded_fora, can go in
I know i can handle this problem with dividing table c into to tables and creating foreign key relationship.
in this demo case i have only a and b, 2 tables but i want to encode thousands of tables with a table like c.
İs it possible to create a dynamic check constraint on a table which selects c table for the inputs that have permision?
Or do i have to use after insert, update triggers on table a and b to ensure this functionality?
Is there a smarter implementation for this need, may be a design change?
Thank you,
Kind regards.

Hi Tonguç,
A small design change makes it possible to do this with simple foreign key constraints.
I would do something like:

Using a function in a check constraint

Hi,
I created a domain table(id, code, domain_code, description) and foreign keys to this table. To ensure that a valid domain is put in the column I created a function that returns a boolean and has two parameters (id and domain_code). It returns true if the id and domain belong together.
I want to know if it is possible to create a check constraint which validates the data in the refering table with the data in the domain table.
Does anyone know if this is possible? Or do I have to use a db-trigger?
Regards,
Romano

It still sounds like all you need is a foreign key constraint. Please see the example below, based on your revised criteria.
scott@ORA92> create table domain

3      code         number,

MView refresh error on 10gR2..(unique constraint error)

Hi. all.
The database is 2-node RAC 10gR2 on SunOS.
Today morining, I got the following error.
EXEC dbms_refresh.refresh('"ODSFAB"."CURRENTWIP"');
ORA-12008: error in materialized view refresh path
ORA-00001: unique constraint (ODSFAB.CURRENTWIP_GLASS_IDX) violated

ORA-06512: at "SYS.DBMS_IREFRESH", line 683
ORA-06512: at "SYS.DBMS_REFRESH", line 195
ORA-06512: at line 1
I checked both the source and target table, but there is no unique-key confliction.
The source table has no unique index, but the target table have one unique index
for a business purpose.
Finally, I dropped the miew log on a source table and mview , and recreated mview
log and mview with the same unique constraint and the same data.
I do not understand why I got "Unique constraint error".
Any advice will be welcomed.
Thanks in advance.
Have a good day.
Best Regards.

Let us say column A is the unique key on target DB and exists in source DB.
Now, on source DB,
- Value 'X' is inserted in col A
- Value "X" is again inserted in col A (or updated on colA)
- Then one of these 2 rows is deleted
Now, "if" Oracle applies all the transactions from the source to target in the
same sequence as they occured, there is chance you can get unique error.you do
But, if a full refresh, there won't be error.I would say that is a very plausible explanation. Somewhat difficult to verify, in the absence of low-level auditing on the source database.
The situation as described is a bit yucky. Is there no way of putting a unique key on the table in the source database? If not, it seems to me that this scenario is bound to re-occur.

How to identify the constraint error

Hi,
Well, are you trying to do a batch input on infotype 0000? If yes you need to check that the proposed values respects the time constraint, meaning no gap, no overlaps and no inversions. Also fields SUBTY, OBJPS, SPRPS and SEQNR must remain initial when processing IT0000...

Toplink 10.1.3.1 Unique Constraint error

Hi All,
I'm working with toplink 10.1.3.1 using JDeveloper 10.1.3.1.
When I'm using the Sequence in the toplink work bench, I'm getting the unique constraint error.
What i did was, I checked the "Use sequencing" check box and filled the sequence name , table name and field in the toplink workbench wizard.
And I kept true for "Use Native Sequencing" in the sequence of login tab for sessions.xml default file. And checked the preallocation Size and set to the minimum value of the sequence. I didn't checked the "Table", "Name Field" and "Counter Field" check boxes.
The sequence is getting incremented for every execution. Its not getting the actual sequence current value. I don't know whether the value is getting cached.
for example if the actual sequence number in the database is 1740
but when I am running the toplink query It is generating the sequence number like 1738 and it is giving the Unique constraint when I am clicking on the button for three times (ie 1739,1740,1741)it is inserting successfully into the database.
But when I am running the application again then it is generating the sequence number as 1739 I am unable to understand where I am going wrong.
If I test The sequence in SQL Work Sheet it was working fine.
could anyone suggest me the correct way of using the sequence in the toplink workbench.
the Sequence was created using JDeveloper wizard with Increment 1.
Thanks in advance,
regards,
Satish Dasari.

Hi,
Satish,Thanks for your reply.
Let me tell the scenario. I have two tables A and B. First I am inserting an event_no in table A. and after that I read the data from table A including event_no and I am going to insert it into table B. Rarely I am getting an exception like Unique constraint violation error.
I kept native sequencing true,preallocation size 1, Min value=1, Max-value=9999999, increment by 1, cache size=10, Enabled refresh only if new version.
What are all the values that i need to be changed in order to recover from this error. Our application is running in a load balancing environment.
Note: I am not able to simulate this in my desktop environment.

Oracle check constraint bug ?

Hi,
This is an 'interesting' bug:
create table mytable (
id number,
status number,
constraint mytable_pk primary key (id)
insert into mytable (id, status) values (1, 0);
insert into mytable (id, status) values (2, -1);
On XE (10.2.0.1) and 10.2.0.4:
Following command gives the expected ORA-02293 error (using string values instead of numbers): alter table mytable add constraint mytable_status_chk check (status in ('0', '1'));
BUT no error with the following command: alter table mytable add constraint mytable_status_chk check (status in ('-1', '0', '1'));
On XE:
The query select * from mytable where status=0 returns no records until the constraint is dropped again !
Best regards,
Serge

I don't have access to any 10.x or XE currently and cannot reproduce on EE 9.2.0.9 or 11.1.0.6.
It's possible that you're running into an optimizer issue with the constraint.
This might be visible if you run an explain plan on the statement, get the execution plan via dbms_xplan.display and check the predicates section both with and without the constraint.
I take it that you don't get the problem if you use a check constraint with numbers not strings.
I wonder also whether it makes a difference if you declare status as not null.

How to Disable check constraint in cronacle

Hi All,
We found that one job failed in cronacle with the following error
*ORA-20800: JCS-02138: problem with parameter "PRINT_BANNERPAGE"
SAP recommended the soultion saying
Disable the "Check Constraints" that are being used in the scripts currently in Cronacle or apply some patch.So we want to explore the first option i.e check constraint
Can any one help me in Regarding the check constraints.
Thanks in advance
shylaja

Hi,
Scripts can have check constraints and reference contraints, you will find these under the script properties when you edit the script.
I would set the constraint to optional, meaning that you still have the dropdown available but it no longer complains if it does not like the chosen value.

Anton.

Problem in creating CHECK constraint

While creating a table, i want to apply a CHECK constraint, that pension_amount should be in accordance of pension_code, i am getting error mentioned below.
CREATE TABLE pension_amount_check

   pension_code   NUMBER (1),
   CONSTRAINT amount_chk CHECK
      (CASE
          WHEN pension_code = 1 THEN (pension_amount = 3000 OR pension_amount > 3000)
          WHEN pension_code = 2 THEN pension_amount = 1500
       end)
ORA-00907: missing right parenthesisHow i can resolve this.

   CONSTRAINT amount_chk CHECK
         (pension_code = 1 AND pension_amount >= 3000)
          OR
