In foreign key creation

hi
i created a foreign key for a table .But the foreign key table is accepting all values , not only the check table content. why?

Creating Foreign Keys Procedure
In the field maintenance screen of the table, select the check field and choose symbol of KEY
If the domain of the check field has a value table, you can have the system create a proposal with the value table as check table. In this case a proposal will be made for the field assignment in the foreign key.
If the domain does not have a value table or if you reject the proposal, the screen for foreign key maintenance appears without proposals. In this case, enter the check table and save your entries. The check table must have a key field to which the domain of the check field is assigned.
You can then let the system make a proposal for assigning of the foreign key fields to the key fields of the check fields. The system attempts to assign the key fields of the check table to fields of the table with the same domain. If you do not want a proposal, the key fields of the check table are listed and you must assign them to suitable fields of the foreign key table.
Enter an explanatory short text in the field Short text.
The short text provides a technical documentation of the meaning of the foreign key.
Choose Copy. The foreign key is saved and you return to the maintenance screen for the table.

Foreign key creation is very slow

Hello,
We are about to migrate a database from 9iR2 to 10g by doing export/import.
One of the last steps of the migration, after the import, is to create constraints and indexes. The foreign key creation process is lasting about 7 hours, and this is something we cannot afford. How could we speed up this process of foreign key creation?
Thanks in advance,
Eva

Look at the statement (using enterprise manager, SQL*Plus, sql trace or whatever) while the foreign keys are enabled/created. Basically for following tables:
SQL> create table big as select * from dba_source;
Table created.
SQL> create table big1 as select * from dba_source;
Table created.
SQL> alter table big add constraint big_pk primary key (owner, name, type, line, text);
Table altered.and following foreign key:
SQL> alter table big1 add constraint big1_big_fk
2 foreign key (owner, name, type, line, text)
3 references big (owner, name, type, line, text);the statement is:
select /*+ all_rows ordered */ A.rowid, :1, :2, :3
from
"GINTS"."BIG1" A , "GINTS"."BIG" B where( "A"."OWNER" is not null and
"A"."NAME" is not null and "A"."TYPE" is not null and "A"."LINE" is not
null and "A"."TEXT" is not null) and( "B"."OWNER" (+)= "A"."OWNER" and
"B"."NAME" (+)= "A"."NAME" and "B"."TYPE" (+)= "A"."TYPE" and "B"."LINE" (+)
= "A"."LINE" and "B"."TEXT" (+)= "A"."TEXT") and( "B"."OWNER" is null or
"B"."NAME" is null or "B"."TYPE" is null or "B"."LINE" is null or
"B"."TEXT" is null)As usually such statement can be executed using various execution plans. And as usual some are better than other for example I could manage 2 variants:

So I'v managed to get it using:
1) dbms_stats to compute stats on these table so that Oracle understand that these are really large tables
2) altering session to use manual workarea size policy and give more resources for hash joins and sorts:
SQL> alter session set workarea_size_policy= manual;
Session altered.
Elapsed: 00:00:00.01
SQL> alter session set sort_area_size = 1000000000;
Session altered.
Elapsed: 00:00:00.01
SQL> alter session set hash_area_size = 1000000000;So the trick is - understand the bottleneck and trying to do something about it. In my case I cannot do much more because everything now is dependant on disks and I cannot make my pc much faster :)))
Another options is to create FKses either disabled and enable them later on or create enabled but not validate them. This is almost instantenous as you can see in the following code snippet. Of course that might give some implications later, especially if you create them disabled :)
SQL> alter table big1 add constraint big1_big_fk
2 foreign key (owner, name, type, line, text)
3 references big (owner, name, type, line, text)
4 disable;
Table altered.

Problem in Foreign key creation

Hi,
I have a requirement where I need to create a foreign key in a ztable which points to the SPRAS field of table T002.Now this requires that the domain of this custom field should be the same as SPRAS. But domain SPRAS has got a conversion exit.For my case, I need to have different conversion exit for the customer field.
So can you please suggest how I can achieve both the things:-
1.Creating a PK-FK relatioship with the table field T002-SPRAS
2. Create a conversion-exit at the domain level of the custom field.
Thanks,
Samrat

Hi,
I am confused with your requirement.
Lets understand why we have conversion exit ..
Conversion Exit 1
Ex: Input -- 'EN' Conversion exit would change it to 'E' and store in DB
Conversion Exit 2
Ex: Input -- 'EL' Conversion exit would change it to 'E' and store in DB
so 2 conversion exit perform 2 separate task...Right !!!
Now lets assume that your zfield uses conversion exit 2 and t002 uses conversion exit 1.If you create a foreign key to zfield to spras of t002
Input - 'EL' conversion exit will convert it to 'E' and it refers to 'E' of T002 ( but 'E' in t002 is actually 'EN'.
Isnt this wrong ??
I hope i did not confuse you.
Cheers,
KD

Creation of Index for Primary & Foreign Key required?

hi,
i would like to find out if a column is defined as the primary key, do i need to create a separate index for it? or defining a primary key will tell the db to automatically create an index for it?
does foreign key have the same behavior as the primary key constraint?
thanks!

How can I create a new entry without using LOV for foreign keys.

Referring to TUHRA sample application based on HR database schema. JDeveloper 10.1.3.0.4
How can I create a new employee without using LOV for the foreign key "job_id".
On the first page I would like to choose the job_title from adf read-only table.
After clicking on the "create new employee button" a creation form appears in which the job_id field is set with previous selection.

Hi,
usually the foreign key is only set if the VO you select is dependent from a master. If e.g. you have DepartmentsVO1 that has an EmployeeVO3 as its nested VO, then creating a new instance of employees automatically add the foreign key. If you add EmployeesVO1, which is not dependent to DepartmensVO1, then the foreign key is not set. So if this is the case in THURA (keep in mind that this is not an Oracle demo but a sample used in a book about ADF) then all you need is to take the independent VO when building the new employee form.

Foreign key Mapping based on Data - in SQL Developer Data modeler

Team
Do SQL Developer Data modeler supports Foreign Key mapping based on the Data in the Schema rather defined at the DDL ? For e.g if we implement a Objects Relation ship mapping in Data base, we don't define Foreign keys at table creation.
Toad does this feature through "AUTOMATIC FOREIGN KEYS MAPPING IN TOAD DATA MODELER" more info at (http://toadworld.com/Blogs/tabid/67/EntryId/905/Automatic-Foreign-Keys-Mapping-in-Toad-Data-Modeler.aspx)
any one know how to implement through some scripts also helps me
Regards
Raj

If you have table PKs defined and the candidate columns match those PK columns, then you can use the Discover Foreign Keys utility. Right mouse over the relational model name (node) in the left browser. It is about half way down the menu. I did a blog post about it last week on kentgraziano.com.

How to apply Foreign Keys on top of a Common Lookup table

I have an issue where i am mandated to enforce RI on an applications database (a good thing). but I have several common lookup tables where many of the "codes" reside for many different code types. I also have the mandate that i cannot change the
underlying DDL to make composite keys to match the codes table PK. I am currently looking at creating indexed views on top of the Codes table to seperate the logical tables it contains. This is several hundred views. Although doable is there another solution
I am not seeing? I have scoured the web in search of an answer knowing I cannot be the only SQL developer in this situation. I do know that I do not want to write several hundred triggers to enforce RI. Table schema below, the CdValue column is the column
that is used throughout the hundreds of tables that use this codes table, and their corresponding column is not named the same.
CREATE TABLE dbo.CodesTable (
PartyGrpId INT  NOT NULL
, CdTyp  VARCHAR ( 8 ) NOT NULL
, CompId INT  NOT NULL
, CdValue VARCHAR ( 8 ) NOT NULL
, CdValueDesc VARCHAR ( 255 ) NULL
, AltValueDesc VARCHAR ( 100 ) NULL
, DefaultInd CHAR ( 1 ) NULL
, OrderNum SMALLINT NULL
, ActiveCd CHAR ( 1 ) NULL
, ExpireDtm SMALLDATETIME NULL
, EffectDtm SMALLDATETIME NULL
, ModById INT  NULL
, ModDtm SMALLDATETIME NULL
, CreateById INT  NULL
, CreateDtm SMALLDATETIME NULL
, CONSTRAINT PC_dbo_EcdDetail
    PRIMARY KEY CLUSTERED ( PartyGrpId ASC, CdTyp ASC, CompId ASC, CdValue ASC )
    ON FG_Data
) ON FG_Data;
I did though run into one forum where a person brought up a great idea. Filtered Foreign Keys, what a novel concept, if it could work it would make so much less code to fix an issue like this. :)
ALTER TABLE dbo.BusinessStatus WITH NOCHECK
ADD CONSTRAINT FK_dbo_BusinessStatus_CodesTable FOREIGN KEY (LoanStsDtCd) REFERENCES dbo.CodesTable (CdValue) WHERE CdTyp = 'Status'
U.S. Army Airborne! The only way to fly

>> I have several common lookup tables where many of the "codes" reside for many different code types. <<
No! This is called “Automobiles, S quids and Lady Gaga” SQL and laugh at you or fire you or both. A table is a set; a set has one and only one kind of element it it. This is the basis of RDBMS and First Normal Form.
This is so bad it has a name; OTLT for “One True Lookup Table” ;I give an example of how stupid this in one of my books where a Dewey Decimal Classification for Churches is the same as the ICD code for deformed testicles.
There is no such crap as a “generic_type_code” in RDBMS. It either a “<something in particular>_type” or a “<something in particular>_code” in data modeling and the ISO-11179 standards.
You have more NULL-able columns in one table than you should have in an entire schema!
You have audit data (creation and modification) in the row under audit. This is both stupid and illegal. You cannot expose the audit trail to the data user by law. When you delete a row, you also destroy the audit trail –Doh!
You have no CHECK() constraint on the (effective_date, expiry_date) pair.
Putting “_table” in a table name is a design error called a “tibble” to make fun of how silly it. You might want to download the PDF of bad SQL code smells from Red Gate so you can avoid things like this.
>> the CdValue column is the column that is used throughout the hundreds of tables that use this codes table, and their corresponding column is not named the same. <<
“_value” and “_code” are both what ISO-1179 calls an attribute property. It is a silly as a list of adjectives without a noun.
Each encoding is a separate table in a valid schema, each with its own validation and verification. You have to stop doing this. This is fundamental!!

Using FOreign key constraints on tables in database.

I am student and novice in the field of ORACLE and PL/SQL and Database Creation. I had created a database consisting tables and got problem while applying foreign key constraints.
CUST_MSTR
CREATE TABLE "DBA_BANKSYS"."CUST_MSTR"("CUST_NO" VARCHAR2(10),
"FNAME" VARCHAR2(25), "MNAME" VARCHAR2(25), "LNAME" VARCHAR2(25),

CREATE TABLE "DBA_BANKSYS"."NOMINEE_MSTR"("NOMINEE_NO" VARCHAR2(10),
"ACCT_FD_NO" VARCHAR2(10), "NAME" VARCHAR2(75), "DOB" DATE,

(NOMINEE_NO is primary key )
--ADDR_DTLS
CREATE TABLE "DBA_BANKSYS"."ADDR_DTLS"("ADDR_NO" NUMBER(6),
"CODE_NO" VARCHAR2(10),      "ADDR_TYPE" VARCHAR2(1), "ADDR1" VARCHAR2(50),
"ADDR2" VARCHAR2(50), "CITY" VARCHAR2(25), "STATE" VARCHAR2(25),
"PINCODE" VARCHAR2(6));
( ADDR_NO is primary key )
Problem: I want to apply foreign key constraints on ADDR_DTLS table so that Before inserting value in ADDR_DTLS table it must check, VALUE in ADDR_DTLS.CODE_NO must be PRESENT either in attribute value CUST_MSTR.CODE_NO or EMP_MSTR.CODE_NO or NOMINEE_MSTR.CODE_NO table .
I applied the foreign key constraints using this syntax
CREATE TABLE "DBA_BANKSYS"."ADDR_DTLS"("ADDR_NO" NUMBER(6),
"CODE_NO" VARCHAR2(10),      "ADDR_TYPE" VARCHAR2(1), "ADDR1" VARCHAR2(50),
"ADDR2" VARCHAR2(50), "CITY" VARCHAR2(25), "STATE" VARCHAR2(25),
"PINCODE" VARCHAR2(6),
constraints fk_add foreign key CODE_NO references CUST_MSTR. CODE_NO,
constraints fk_add1 foreign key CODE_NO references EMP_MSTR. CODE_NO,
constraints fk_add2 foreign key CODE_NO references NOMINEE_MSTR.CODE_NO);
(foreign key)
ADDR_DTLS.CODE_NO ->CUST_MSTR.CUST_NO
ADDR_DTLS.CODE_NO ->NOMINEE_MSTR.NOMINEE_NO
ADDR_DTLS.CODE_NO ->BRANCH_MSTR.BRANCH_NO
ADDR_DTLS.CODE_NO ->EMP_MSTR.EMP_NO
When I applied foreign key constraints this way, its gives a error called foreign key constraints violation. (I understand that, its searches the attribute value of ADDR_DTLS.CODE_NO in all the three tables must be present then the value will be inserted. But I want, if the value is in any of the three table then its should insert the value or its gives an error.)
Please help me out, though i put the question and i want too know how to apply the forign key in this way. and is there any other option if foreign key implementation is not pssible.

If you are on 11g you can use ON DELETE SET NULL:
CREATE TABLE addr_dtls
( addr_no          NUMBER(6) CONSTRAINT addr_pk PRIMARY KEY
, addr_cust_no     CONSTRAINT addr_cust_fk    REFERENCES cust_mstr    ON DELETE SET NULL
, addr_emp_no      CONSTRAINT addr_emp_fk     REFERENCES emp_mstr     ON DELETE SET NULL
, addr_nominee_no CONSTRAINT addr_nominee_fk REFERENCES nominee_mstr ON DELETE SET NULL
, addr_type        VARCHAR2(1)
, addr1            VARCHAR2(50)
, addr2            VARCHAR2(50)
, city             VARCHAR2(25)
, state            VARCHAR2(25)
, pincode          VARCHAR2(6) );In earlier versions you'll need to code some application logic to do something similar when a parent row is deleted, as otherwise the only options are to delete the dependent rows or raise an error.
btw table names can be up to 30 characters and don't need to end with MSTR or DTLS, so for example CUSTOMERS and ADDRESSES might be more readable than CUST_MSTR and ADDR_DTLS. Also if the Customer/Employee/Nominee PKs are generated from a sequence they should be numeric.

Foreign key cannot be created for the selected field A907-MWSKZ

Dear Guru's,
I am having the requirement for creation of access sequence having country/Plant/vendor/tax code but during creation of condition table i am getting the error as
Foreign key cannot be created for the selected field A907-MWSKZ.
Anything i am missing please let me know.

Hi Umesh,
Actually i am also facing exactly the same problem as mentioned by you that is "Foreign key cannot be created for the selected field A769-MWSKZ ".
I think you found some solution regarding this..can you please help me to solve it.
Looking forward for your prompt reply..
Thanks & Regards,

Logical foreign key display values

I have a schema in which the primary keys are auto generated numbers. Foreign keys exist from child tables to the primary key of the parent.
I have figured out how to change auto generated forms to display a dropdown list of display/values to the user on insert or update instead of the meaningless number.
What I can't figure out how to do is have the generated report show the display that I am looking for without losing the ability to edit the child record. As soon as I manipulate the query to include another table I lose the icon in the application to edit the row.
Is it possible to keep the edit icon on the report while showing logical values instead of actual ones?
Thanks in advance,
Chris S.

We'll use a football analogy because it's time for the ployoffs.
Let's create a TEAMS table and a DIVISIONS table.
TEAMS consists of:
TEAM_ID NUMBER -> PK
LOCATION VARCHAR2(35)
TEAM_NAME VARCHAR2(35)
and DIVISIONS consists of:
DIVISION_ID NUMBER -> PK
DIV_NAME VARCHAR2(35)
Now there can't just be a link from a team to a division because they move around a bit. The Detroit Lions used to be in the NFC Central. That doesn't exist anymore and now they are in the NFC North. (Please set aside the fact that the NFC should be a part of the conferences table).
This means that I would create a table to link the TEAM record to a DIVISION record with the season that the team became a part of the division and potentially the last season that they were in that division. This table will be called DIVISION_TEAM_XREF and looks like this:
LINK_ID NUMBER -> PK
DIVISION_ID NUMBER -> FK(DIVISIONS.DIVISION_ID)
TEAM_ID NUMBER -> FK(TEAMS.TEAM_ID)
SEASON_EFF NUMBER(4) (actually a year maybe a VARCHAR2 would be better)
SEASON_TERM NUMBER(4) (nullable)
Now I created all of that through HTML DB with foreign keys from the XREF table to the teams and divisions tables. Then I create an application throught the application builder. I choose report and form and the application type like the demo. for each of the three tables. Choose a theme and walah there is an application with all three tables. If I add data to TEAMS or DIVISIONS I can see them in the report page that is created and there is an icon to the left of each row which when clicked will allow me to edit the row.
The problem comes with my XREF table. The creation screen is just a form which expects me to know the auto generated number that was created for my division and team. I have figured out how to change this in the application builder so that it is a drop down list built from a query of the respective table.
Once I create a record I can see it in the report page for the XREF table. This page has the option to edit the record but the values on the screen are the auto generated numbers that don't mean anything to a user. When I change this page to use display values from the parent tables I lose the edit icon.
Here is the original query that the application builder used:
select
"LINK_ID",
"DIVISION_ID",
"TEAM_ID",
"SEASON_EFF",
"SEASON_TERM"
from "DIVISION_TEAM_XREF"
and here is what I would like to change it to:
select
XREF.LINK_ID "LINK_ID",
DIV.DIV_NAME "DIVISION",
TEAM.TEAM_NAME "TEAM",
XREF.SEASON_EFF "SEASON_EFF",
XREF.SEASON_TERM "SEASON_TERM"
from "DIVISION_TEAM_XREF" XREF, DIVISIONS DIV, TEAMS TEAM
where XREF.DIVISION_ID = DIV.DIVISION_ID
and XREF.TEAM_ID = TEAM.TEAM_ID
Sorry for the long post. Hope that clarifies.

Why can't global temporary tables have foreign keys?

Hi,
I have a forms module which shows two blocks. The first block is based on a normal database table EMP and the second one is based on a global temporary table SAL_TEMP. There is a master-detail relation between the two blocks. So far, in Designer I created two normal database tables EMP and SAL_TEMP and created a foreign key with validation level "none" from the table SAL_TEMP to the table EMP. By creating the foreign key, Designer generates code to automatically synchronize the data between the master and the detail block in my form.
In the latest version of Designer it is finally possible to indicate a table as a global temporary table. But when I try to change my table SAL_TEMP to a global temporary table (session) I get an error that this is not allowed because my table contains foreign keys. So the Designer team finally implemented this feature but it is useless to me.
Can someone explain to me the reason of this restriction?
Vincent

Just out of curiosity - which version of Designer supports the creation of global temp tables? We are running version 9.0.2.80.6 and, as far as I am award, this does not support it (unless I am being really thick!) - is this new 10g Dev. Suite functionality?
thanks,
Pete

Foreign keys issues

hi guys,
i m using jdeveloper 11 release 2
i have created 3 tables one for employee,second for evaluator,third for screening.
by creating the relationship pk empno(employee) become fk (evaluator) ,then pk evaluatorNo become fk for screening
i would like when using the LOV ON the screening form to display the employeename and save the evaluatorNo on the database.
the issue when i select the LOV ON evaluatorNo,on the edit LOV
I select the list of the data source,on the available object view i select the employeeEO shuttled to the view accessors ( screeningVO)
back on the edit LOV ,I select empNo under list of attributes.
then i have view attribute as evaluatorNo
and list attribute as empNo
then on the UI Hints i select employeename
when running the application it shows the employee names on the list box
but trying to save it says foreign key not found
any help
regards

Some trouble-shooting ideas:
1. Are you using the application model tester or is this on a web page? Try it on the am tester. If that doesn't work, then something is wrong with your model.
2. How are the primary keys being created? Are you creating first a parent record, then a child record? Is the key for the parent being created? Does the child foreign key populate when you create that record? Have you tried saving the parent record first, then creating the child record?
3. What method are you using for primary key creation? DBSequence (database trigger) or create method? There are differences in how they are created and that may affect the behavior of the parent/child relationship, or lack thereof.

New Business Components doesn't load with their foreign keys

Hi,
When your database schema has already been defined and nothing moves, the creation of Business Components in JDeveloper works pretty well.
When you are developing a real application and sometimes the customer changes his mind or something, you have to add some Business Components later in the process.
My question, why associations and links doesn't follow the creation of new business object?
Example 1
I load every database object I need. All associations and links are created.
Example 2
I have let say three tables. I create my new Business Components by selecting only 2 tables out of 3. If there are foreign keys, they are loaded.
Now, I want to create the last business components (table 3 of 3), and this table got foreign keys pointing to one of the two previous tables I just loaded.
Surprise, it won't load any foreign key.
I have tried multiples ways to synchronise object, I don't see it working. So I have to create every associations and links myself. Anybody knows a trick that they want to share for this kind of situation?
Thanks

Hi,
actuallly Chris Muir brought up the idea to make the entity wizard more intelligent of this. However, this is currently a suggestion by him and we work with the developers to get this idea validated and eventually in the product. Since then you will have to create relations manually. Note however that in this ADF BC behaves like the EJB entities from table wizard that also can only look up dependencies if the table is part of the selection. In your case, you select a single table and the table has a FK to another table. However, the other table is not part of the selection so why would ADF BC want to create the key relation ship. Before you say, it could parse your project, let me add that related objects may be saved in ADF libraries, which means we would parse the class path, which may be a long time waiting for you for the IDE to get back to you. So this requzrement - though valid - needs a different approach in the wizards. Until then you will have to build it manually.

Foreign key changing name...

Hi again, and again...! (at least I always punch the helpful and correct buttons ...:P)
Clearly, I lack knowledge about foreign keys.
Of course I searched the web before posting.

This is the strange DSD...
The Team table (equipe) is connected to Rencontre (Meeting)
During a meeting (NoR 1,2 ... incrementation), there is TWO teams : NoEH (Host team) and NoEV (Visiting team)... these are FK for NoE (Team number)
This is so strange...
The Partie (Match) occurs from 3 to 5 times during a Meeting, and the winner is put on the H_ or V_, which only says which team wins... visiting or host
How am I suppose to make a select table stating which team (NoE!!!! not NoeH! or NoeV?!!) won how many games, how many games played, wtc...
Anyone know a tactic to approach this problem?
I was thinking of maybe creating a view for each team to add their wins...?

Hi,
For this case can you post scripts for creation of tables and a minimal data? And also please post the specific problem you are having.
Regards,

Setting foreign keys directly

I've discovered that Kodo (2.4.2) does not like it when I set foreign keys
directly in order to define a relationship. If I set the foreign key and
then call the relationship getter, even in a subsequent transaction, null
is returned. Is this something that is prohibited by the JDO spec, a bug
in Kodo, or something else?

Just use the execute SQL query VI (I believe it's in the advanced palette) and feed it the table creation SQL code you already have.
Try to take over the world!
