How to create a named not null constraint

Hi All,
How to create a table with a named not null constraint?
and how to add a named not null constraint to a table?
Thanks for the help.

Hi,
I guess you are asking for a column inside a table, having a named not null constraint. Am I correct? Try the following.
SQL> create table checktab (col1 varchar2(30) constraint NN_const not null);Is this what you required?
Please post technical questions in respective forums.
Hope that helps.
Savitha.

How to create a single 'not null ' validation for all the items in a page ?

Hi everyone ,
how to create a single 'not null ' validation for all the items in a page ? I have many textfields . Instead of creating 'not null' validation for each item , I would like to create a a single validation control that will serve the purpose
Thanks & Regards

bob , as u said I have done the following :
1) under create button , there are 9 items and for each item I have set Required to 'Yes'
2) under delete button , there is 1 item and have set Required to 'Yes' for the item
3) defined page validation for 9 items under 'create ' button and have set it to fire when 'create ' button clicked
4) defined page validation for 1 item under 'delete ' button and have set it to fire when 'delete ' button clicked
now , when I click 'create' button it even shows for the item under 'Delete ' button that it is a required itemSorry, I didn't see this note. The required template won't work, there is no way to attach it to the button.
The best solution is as the reply a couple replies up
Create 2 page type validations as a PL/SQL with code
1st validation
:P1_ITEM1 IS NOT NULL and :P1_ITEM2 IS NOT NULL ...... and :P1_ITEM9 IS NOT NULL include all 9 items
Set the When Button Pressed to the CREATE button
2nd validation
:P1_ITEM10 IS NOT NULL
Set the When Button Pressed to the DELETE buttonI think that's going to be the easiest way to do it.

NOT and NOT NULL constraints

I saw this posted on Metalinks and the answer was to be found here. I can't seem to find it..... has there been a resolution to this? Unfortunately, I am running into the same problem.
You help is appreciated.
I am trying to create Oracle8i schema from MS SQL Sercer 7.0 using Oracle Migration Workbench and it is not functioning as expected.
Problems are:
=============
1. If the column type is CHAR OR VARCHAR in MS SQL Server and the integrity contraints is NOT NULL or NULL, in Oracle8i it create as NULL only and it not taking the NOT NULL in MS SQL Server to Oracle8i NOT NULL. I can say that it is ignoring the integrity constraint for CHAR OR VARCHAR type while converting to Oracle8i.
Example in MS SQL Server
========================
CREATE TABLE emp (
emp_name CHAR(10) NOT NULL
the tool converts to Oracle8i as
CREATE TABLE emp (
emp_name CHAR(10)
It is ignoring the NOT NULL constraints in Oracle8i and it is happening only for CHAR and VARCHAR data type. Can anyone help me on this how to rectify the problem in Migration Workbench. ....... "

We reported this for the EA's, but got little response and obviously no resolution.

In Oracle ebook:
Oracle® Database Reference
10g Release 2 (10.2)
Part Number B14237-02
the comments about the NULLBLE column are as follows:
"Specifies whether a column allows NULLs. Value is N if there is a NOT NULL constraint on the column or if the column is part of a PRIMARY KEY. The constraint should be in an ENABLE VALIDATE state."
BUT BY DEFAULT ALL CONSTRAINTS ARE IN VALIDATE STATE
(Ref: Oracle® Database SQL Reference

All_tab_columns says NULLABLE = 'Y' while there is a NOT NULL constraint

Hi all,
I created a table MANT (here is the script) :
CREATE TABLE DMI.MANT
MANT     NUMBER(7)                            NOT NULL,
SPER     NUMBER(7)                            NOT NULL,
RANT     VARCHAR2(10 BYTE)                    NOT NULL,
ANT      VARCHAR2(200 BYTE),
CMT      VARCHAR2(800 BYTE),
PERIODE VARCHAR2(200 BYTE),
DU       DATE,
USR      VARCHAR2(10 BYTE),
DTE      DATE
)Then I added a column called RSMF :
ALTER TABLE DMI.MANT
ADD (RSMF VARCHAR2(100 BYTE));and added a check constraint :
ALTER TABLE DMI.MANT ADD
CONSTRAINT RSMF_NOT_NULL
CHECK (RSMF IS NOT NULL)
ENABLE
NOVALIDATEI had to add NOVALIDATE clause because all the records had a null value. So to validate the constraint I simply executed the following update
update dmi.mant set rsmf = 'yy';and then validate the contraint with :
ALTER TABLE DMI.MANT
MODIFY CONSTRAINT RSMF_NOT_NULL
VALIDATE;The problem comes when I query ALL_TAB_COLUMNS table...
Select OWNER,TABLE_NAME,COLUMN_NAME,DATA_TYPE,DATA_LENGTH,NULLABLE
from all_tab_columns
where table_name = 'MANT'
   and owner = 'DMI'
   and COLUMN_NAME = 'RSMF';Why does the ALL_TAB_COLUMNS table gives for RSMF column a NULLABLE value equals to 'Y' while there is a validated check NOT NULL constraint on it ?
It's annoying because I want to get all the NOT NULL columns in a given table and here the SRMF column is not returned...
Here is the result :
OWNER |TABLE_NAME |COLUMN_NAME |DATA_TYPE |DATA_LENGTH |NULLABLE
DMI    |MANT       |RSMF         |VARCHAR2   |100          |YThks for your replies...

NULLABLE would be true if you created the table like this:
create table x (a not null)
but not if you add a check constraint after the fact.

Issue in adding not null constraint on 250 G table with 50 million rows.

Guys,
I need to add not null constraint on 2 column of a table with 50 million rows and ~250 GB in size, These 2 columns are newly added and I have also update the value for each of these columns to not null for each row.
After that I am adding not null constraint on these 2 columns this is taking 1 hour to complete, Is there any way to speed up this, I don't want to use ENABLE NOVALIDATE option or rather I can't use that option.

Hi Parga,
You need to declare the variable at Interface controller and need to map this at the context level.
Like a variable declared at web dynpro component context level can be used among all views.
every web dynpro component have an Interface component. this can be used in other components where this perticular component is used it is also have a Context.
For more info Take Usage of Component Controller Examples.

How to create server named sets in Essbase 9.3.1

Hi there,
I'm writing software against Essbase 9.3.1 Analytic Services right now and am trying to find out whether or not Essbase supports server named sets (not the session/query-scoped named sets that are created from CREATE SET or WITH respectively).

Anyone know how to create/access this? If so, what tool (essmsh.exe, Administration Services?) is needed to do this?
Thanks,
J

Yes you need to create one DSN connection and you have to use DSN name and login details at the time of building/loading of the outline.
Create DSN
Goto Administrative tools -> DataSources (ODBC) and add the DSN name and specify the Server name of SQL and login details and database.
goto data prep editor and click on File Menu and Click on Open SQL option Next window opens.
There you have to enter the details of the DSN connection and SQL query to build/load.

When primary table is also join table and you have NOT NULL constraints

Hi,
Me again. This is similar to the message titled "Problem with an
optional 1 to 1 relationship modelled using a link table". Whats
different about this case is we are dealing with a one to many relationship.
Given this SQL:
create table person (
pid INTEGER(10) NOT NULL,
language_code VARCHAR(3) NOT NULL
create table language_person (
pid INTEGER(10) NOT NULL REFERENCES person(pid),
language_code VARCHAR(3) NOT NULL,
first_name VARCHAR(20) NOT NULL
I wrote these classes (abbreviated)
Person:
* @jdo:persist
* @jdo:identity-type application
* @jdo:objectid-class PersonId
* @jdo:requires-extent false
* @jdo:extension vendor-name="kodo" key="table"
* value="PERSON"
* @jdo:extension vendor-name="kodo" key="lock-column"
* value="none"
* @jdo:extension vendor-name="kodo" key="class-column"
* value="none"
public class Person {
* @jdo:primary-key true
* @jdo:extension vendor-name="kodo" key="data-column"
* value="PID"
private int pid;
* @jdo:extension vendor-name="kodo" key="data-column"
* value="LANGUAGE_CODE"
private String languageCode;
* @jdo:collection element-type="LanguagePerson"
* @jdo:extension vendor-name="kodo" key="pid-data-column"
* value="PID"
* @jdo:extension vendor-name="kodo" key="table"
* value="LANGUAGE_PERSON"
* @jdo:extension vendor-name="kodo" key="pid-ref-column"
* value="PID"
* @jdo:extension vendor-name="kodo"
key="languageCode-data-column"
* value="LANGUAGE_CODE"
* @jdo:extension vendor-name="kodo"
key="languageCode-ref-column"
* value="LANGUAGE_CODE"
private Set languagePersons = new HashSet();
public Person(int pid, String languageCode) {
this.pid = pid;
this.languageCode = languageCode;
public void addLanguagePerson(LanguagePerson languagePerson) {
languagePersons.add(languagePerson);
public Set getLanguagePersons() {
return languagePersons;
LANGUAGE_PERSON
* @jdo:persist
* @jdo:identity-type application
* @jdo:objectid-class LanguagePersonId
* @jdo:requires-extent false
* @jdo:extension vendor-name="kodo" key="table"
* value="LANGUAGE_PERSON"
* @jdo:extension vendor-name="kodo" key="lock-column"
* value="none"
* @jdo:extension vendor-name="kodo" key="class-column"
* value="none"
public class LanguagePerson {
* @jdo:primary-key true
* @jdo:extension vendor-name="kodo" key="data-column"
* value="PID"
private int pid;
* @jdo:primary-key true
* @jdo:extension vendor-name="kodo" key="data-column"
* value="LANGUAGE_CODE"
private String languageCode;
* @jdo:extension vendor-name="kodo" key="data-column"
* value="FIRST_NAME"
private String firstName;
public LanguagePerson(int pid, String languageCode, String firstName) {
this.pid = pid;
this.languageCode = languageCode;
this.firstName = firstName;
And then I do this:
PersistenceManager pm = JDOFactory.getPersistenceManager();
pm.currentTransaction().begin();
final Person person = new Person(1,"EN");
final LanguagePerson languagePerson = new
LanguagePerson(1,"EN","Mike");
person.addLanguagePerson(languagePerson);
pm.makePersistent(person);
pm.currentTransaction().commit();
The SQL that issues forth is this:
1125 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
preparing statement <17089909>: INSERT INTO PERSON(LANGUAGE_CODE, PID)
VALUES (?, ?)
1125 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
executing statement <17089909>: [reused=1;params={(String)EN,(int)1}]
1125 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
preparing statement <9818046>: INSERT INTO
LANGUAGE_PERSON(LANGUAGE_CODE, PID) VALUES (?, ?)
1125 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
executing statement <9818046>: [reused=1;params={(String)EN,(int)1}]
1140 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
preparing statement <24763620>: INSERT INTO LANGUAGE_PERSON(FIRST_NAME,
LANGUAGE_CODE, PID) VALUES (?, ?, ?)
1140 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
executing statement <24763620>:
[reused=1;params={(String)Mike,(String)EN,(int)1}]
And the second INSERT fails on Oracle because FIRST_NAME is null, and
the table definition requires it to be NOT NULL.
Is there anyway I can get Kodo to figure out its dealing with the same
table for inserting the link columns and the full row, and optimize
accordingly i.e do one INSERT for LANGUAGE_PERSON?
I guess my only other options are a) introduce an explicit link table or
b) define a custom mapping?
Thanks,
Mike.

There are examples of 1-Many mappings in the documentation:
http://www.solarmetric.com/Software/Documentation/latest/docs/
ref_guide_meta_examples.html
The important point I think you've missed is that right now, 1-many
mappings always require an inverse 1-1 mapping. Again, see the docs
above.
So your LanguagePerson needs a field of type Person, and whenever you add
a LanguagePerson to a Person, make sure to set that LanguagePerson's
Person too. LanguagePerson.person will use the same PID column as
LanguagePeson.pid. Kodo has no problem with having 2 mappings
mapped to the same column.
Kodo 3.0 will allow 1-Many relations without an inverse 1-1.

How to create a Credit Note to the client for purchasing of an Asset last y

Hi,
I have an issue in Asset Accounting as it showed bellow:
Assets depreciation start date is 1st October 2007.
We have run the depreciation up to November 2007.
Than we sold the asset in December.
However, after the end closed year 2007, client returned the asset in 1 st January 2008.
So i need to create a Credit Note to the client for purchasing of an Asset last year, but we don't know how to create it?
We thinks that correct movement should be debit in extraordinary cost / profits account, debit in asset account, credit in accumulated depreciation account and credit in client account.
Plz help. I will assign full points for any useful answer.
Thanks
Edited by: Ricardo Pedro Rodrigues Ferrão on Dec 20, 2007 10:09 AM

How did you sell the asset?
You can just reverse the sale transaction by going to transaction AB08.
Hopefull this may work for you.

Create a field NOT NULL in a z table

Hi,
I want to create a ztable and i need to create in it a field that can't be initial but it's not a field of the key.
Is there any kind of property to set a NOT NULL in the field??.
Thanx.
Jorge

"Initial Values" Column is an Indicator that NOT NULL is forced for that fieldCheck out the documentation below for you reference.
Use
    Select this flag if a field to be inserted in the database is to be
    filled with initial values. The initial value used depends on the data
    type of the field.
    Please note that fields in the database for which the this flag is not
    set can also be filled with initial values.
    When you create a table, all fields of the table can be defined as NOT
    NULL and filled with an initial value. The same applies when converting
    the table. Only when new fields are added or inserted, are these filled
    with initial values. An exception is key fields. These are always filled
    automatically with initial values.
    Restrictions and notes:
    o   The initial value cannot be set for fields of data types LCHR, LRAW,
        and RAW. If the field length is greater than 32, the initial flag
        cannot be set for fields of data type NUMC.
    o   If a new field is inserted in the table and the initial flag is set,
        the complete table is scanned on activation and an UPDATE is made to
        the new field. This can be very time-consuming.
    o   If the initial flag is set for an included structure, this means
        that the attributes from the structure are transferred. That is,
        exactly those fields which are marked as initial in the definition
        have this attribute in the table as well.

How to create business rule for 'Integrity constraint - child not found'

Hello, I am using JDeveloper 11.1.2.3.0.
When an integrity constraint is violated an error message coming from database is displayed in my application. In this case is the error "integrity constraint (TableName) violated - child record found "
How can I personalize the error shown in this case? I tried with EO business rules but I couldn't find this key, only "Key exists" or "UniqueKey".
Can anyone help?

How to create a repository(not just custom) using your hard drive

I don't know if many people know about this, so I am giving this a shot. There are three major articles on wiki.archlinux.org: Custom local repository,
Using a CD-ROM as a repository, and Offline Installation of Packages. These are available online through the WIKIs at archlinux.org.
I was first confused because when I was reading "Offline installation of packages", I didn't know what these ".db.tar.gz" files where. I came mainly from a Debian / Ubuntu
background (I actually tried many distros before this), so getting used to the way the repository works and no graphical install manager for it. However, I enjoyed a challenge and
I found out that these are database packages that contain descriptions and locations on where these files are located. The ones on the ftp server are already compiled. I don't know if,
however they are compiled with the most recent versions.
With all that said, I thought you had to have it all in one directory in order for this to work, but as it turns out, location is not really an issue. I decided to have a directory reside on the root.
I chose root because it's only for the install of my own packages. I could have done it as a seperate user account, such as "repos" in PCLinuxOS (another distro I tried). I didn't want to have a seperate account for this. Therefore, I created "/root/repository". Within this directory I created directories for all repository archives. I basically did a "cd /mnt/dvd" and migrated to the particular repository directories. I would copy all the "pkg.tar.gz" files into their respective directories with "cp * ~/repository/<name-of-dir>". For intance, I started with the "core" directory, because there was some things I didn't install in the core directory during installation and if the packages needed it, it was there. This follows for the rest of the directories, such as "community", "testing", and "unstable", etc.You can go to the ftp mirrors to find out what directories are available. The main point is that your files should be in the format ".pkg.tar.gz". These are package files that get converted into a sort of database format that as I mentioned, informs the system the description and where the files are located, and so on.
The command to perform this, is "tar -xvf /root/repository/core/core.db.tar.gz *.pkg.tar.gz". You can replace core with whatever repository you are adding. So, for example, "extra.db.tar.gz" would be in the "extra" directory. This information is located in the "Offline installation of packages". The command to create this database is called, "repo-add".
The format for this command is "repo-add /path/to/dir.db.tar.gz *.pkg.tar.gz". So, if it's the core packages you would "cd ~/repository/core" and "repo-add core.db.tar.gz *.pkg.tar.gz".
Then, you need to edit the "/etc/pacman.conf" configuration file for pacman. I basically would comment all out except for the repositories I need. So, for example "[core]" and "/etc/pacman.d/core" would tell where normally the servers are located for these files. This information is located int the "Custom local repository" article.using the "repo-add" command.
Furthermore, I edited each server file located in "/etc/pacman.d/<repository>" where repository is core, extra, etc. I would perform, "nano /etc/pacman.d/core" for example and comment out all servers. I then add a "local repository" by typing in "file:///root/repository/core", saved it, and then did a "pacman -Sy" to update the repository database. Now, I can do "pacman -S <package-name>" where package-name is whatever I wanted to install. Voila! Please let me know of any suggestions, questions, insights, or comments. I hope I'm not missing anything in this article. I do remember using "rm -rf * in the "/var/lib/pacman/<repository>"directories and using "tar xvf <repository>.db.tar.gz". I don't if that something to do with it, though. Be careful with the "rm -rf *" command, because you can erase your hard drive if you are not careful, for those who aren't informed.
P.S. Please note all these are done with the root user.

Also, should I have got ridden of the redundant information if it is contained in the Wiki article and / or taken out the commands on how to apply them and left only with the explanation? Is this what you imply? Sorry if I seem redundant with these questions, but I'm curious so I can improve for the future. I am new to this and open to any suggestion and comments.
Maybe you could either edit the existing wiki pages where they were not clear to you, or else add a new wiki page, or both. Certainly give the whole a clearer (visual) structure, and (if they don't already exist) add links between the connected wiki pages.
Yes that is partly what I mean. Further you could get rid of the information that is not really needed to follow the guide (for example what the command 'repo-add' does. People could if they are interested look it up in the script itself, or you could add it here and link to it).
And yes a bit of structure would be nice. You don't have to nessesarily call it 1,2,3, as long as it has some kind of structure in it (the visual point is very important here). You could take a look at existing wiki pages on the web and see how most of them (not all of them are good of course) are structured.
That's a good point, too. How do I found out what articles are more effective? I am doing research on this particular matter at the moment and came across articles that have tips on technical writing. Could this help in the long run? Or, is it better to get feedback from other users and improve that way? In other words, do first, and ask later, as one user point out?
