Catch foreign key violations in the model, not the database

I must do something wrong, when I want to delete a master that still has details, the application will let me, but the database returns an FK violation error when the commit button is pushed. The association is in the model, there is no viewlink though.
Why doesn't the framework check this before the database does? And how could I make the message more userfriendly? My users have no idea what it means if BLABLA_FK is violated
Thanks in advance

I might have the source of this problem. I have a table that has 2 foreign keys to the same other table. In my RowImpl I get duplicate case labels when I create both viewlinks because the final int gets the name of the referring table.
Doesn't ADF support 2 foreign keys to the same table?
Update: a testcase showed me that I chose the same name for the accessors of 2 different viewlinks, so that was not the problem.

How can I show Foreign Key name in the Data model Table window

Hi,
In one of my table, I had a Foreign Key, but that is not indexed. I want to display the name with in the table second window in realtional data model. If it is indexed, then it is showing in third window. How I can show without indexing that column?
Thanks.

I want to show Foreign Key name in the second window.
Thank you for considering my question,

Changing foreign key name in physical model

If I change foreign key name in physical model, it does not change in relational model. But when I change the name in relational model, the new name appears in physical model. This happens in Data Modeler 2 and 3EA2. Is it a bug or an intentional feature?

it's not a bug - the name in physical model "follows" the name in relational model until name in physical model is changed. It keeps the same value and changes in relational model do not affect it. original behavior can be restored if you set the same name as it is in relational model.
If I change foreign key name in physical model, it does not change in relational modelYou can look at physical model as specific implementation of relational model - changes do not go back in relational model.

How to khow how many foreign key are referenceing the primary key

sir i would like to know that how many foreign key are referencing the primary key of a table
is any command to know the table name
please suggest
thanks in advance..

In the query below, table_name is the name of the table whose primary key is referenced.
SELECT b.owner owner
,b.constraint_name foreign_key
,b.constraint_type constraint_type
,b.table_name referencing_table
,b.r_constraint_name primary_key
,c.table_name referenced_table
,c.column_name referenced_column
FROM all_constraints a
,all_constraints b
,all_cons_columns c
WHERE a.owner = b.owner
AND a.table_name = :table_name
AND a.constraint_type = 'P'
AND b.r_constraint_name = a.constraint_name
AND b.constraint_type = 'R'
AND c.constraint_name = a.constraint_name
AND c.owner = a.owner;
If the name of the primary key is known, the query below
select * from all_constraints where constraint_type = 'R' and r_constraint_name = :pk_name

Catching Alt Key Press with the Key Down Filter Event

I am writing an application that requires specific key combinations using ctrl, shift, and alt in addition to a function key (F1, F2, F3, etc). The application works great except for when I try to catch an alt key press. The alt key press does not seem to fire an event eventhough it is an option in the PlatMods cluster as well as the VKey enum. When I press the alt key when my application is running the cursor changes to a normal mouse pointer from the usual finger pointer and prevents any other key presses from going through (in addition to not firing an event itself).
I have tried completely removing the run-time menu, which doesn't seem to help. I currently discard all keys after I handle them in my event structure.
I really hope that the only solution isn't using a Windows DLL. Any suggestions or ideas at all would be greatly appreciated.
Thanks,
Ames

Hi Ames
As Kileen has said Khalid has already given you a good solution to detect the ALT key.
I have another approach that might let you stick to your event-driven approach. I suggest that you have another loop in your app that polls the keyboard using the Input Device utility vi's. When this poll loop sees an ALT + KEY combo it raises a dynamic user event and will be processed in your event structure. This means you can keep your key down filter event to process the CTRL + KEY and SHIFT + KEY events.
Example attached in 7.1

Primary Key Violation at the time of Moving from primary range to secondary range.

Hi Experts,
I've observed a strange issue in our environment.
we are using sql server 2008 R2 with SP2.
whenever a table is moving from primary range to secondary range on it's identity values, application is getting crashed with the message as below.
Violation of PRIMARY KEY constraint 'PK6'. Cannot insert duplicate key in object 'dbo.TD_TRANN'. The duplicate key value is (17868679).
The statement has been terminated.
OR
Violation of UNIQUE KEY constraint 'IX_TDS_COST'. Cannot insert duplicate key in object 'dbo.TDS_COST'. The duplicate key value is (17, 19431201).
identity ranges were auto managed by replication. agents are running continuous.
please suggest.
Cheers, Vinod Mallolu

Well this is pretty simple, so there are two type of subscriptions (Server and client) in merge replication. So while adding article you provide following parameters:
@pub_identity_range
@identity_range
You can check the details of above parameters on following article:http://msdn.microsoft.com/en-us/library/ms174329.aspx
Snippet
@pub_identity_range= ]
pub_identity_range
Controls the identity range size allocated to a Subscriber with a server subscription when automatic identity range management is used. This identity range is reserved for a republishing Subscriber to allocate to its own Subscribers.
pub_identity_range is bigint, with a default of NULL. You must specify this parameter if
identityrangemanagementoption is auto or if
auto_identity_range is true.
[ @identity_range= ]
identity_range
Controls the identity range size allocated both to the Publisher and to the Subscriber when automatic identity range management is used.
identity_range is bigint, with a default of NULL. You must specify this parameter if
identityrangemanagementoption is auto or if
auto_identity_range is true.
So for example you are adding "Server" type subscription then we consider @pub_identity_range value while assigning the range to that sub. If it is "Client" type subscription in that case we consider @identity_range value.
You could run following query to check the range assigned to each publisher and subscriber:
SELECT B.SUBSCRIBER_SERVER,B.DB_NAME,A.* FROM MSMERGE_IDENTITY_RANGE A,SYSMERGESUBSCRIPTIONS B
WHERE A.SUBID=B.SUBID
This should answer your other question as well.

Wrong order foreign key constraints

Hi,
i have problems with non-deferred foreing key constraints:
I have a table "PERSON" and a table "ADRESSE" which has a foreign key
to "PERSON". Both tables have primary keys with two columns.
In the mappings I use application identity. The mappings are generated by
xdoclet.
We cannot use deferred constraint because we have to support following
databases: Oracle, Firebird, MS SQL, DB2.
I tested the mappings with Oracle and Firebird and got this exception

The foreign key "ADRESSE_PS" was identified correctly.
I've taken a look at the class OracleDictionary and it seems that the
object "ForeignKey" considers only one column from the foreign keys -
but I use foreign keys that include two columns ("MANDANTID", "PERSONID").
Is that right or are foreign keys with two columns allowed by the
OracleDictionary?

That is odd ... Kodo should be identifying the foreign keys and ordering
the statements accordingly. The mappings appear correct to me at first
glance. If you run the "schemagen" tool, does Kodo correctly identify
the foreign key constraints in the database? Can you post the output
from the command so we can take a look?

Code generation - foreign key relationships

I'm using the code/descriptor generation tab to generate classes from existing tables. It offers an option of choosing which relationships to generate, but seems to miss out some of the defined foreign key relationships in the database.
I have three tables, CLIENTS, TXNS and REG
The following constraints are defined in my database:
TXN Primary Key: (TXN_ID)
CLIENTS Primary Key :CLIENT_ID, TXN_ID)
CLIENTS Foriegn KEy : TXN_ID references TXNS
REG Primary Key: CLIENT_ID, TXN_ID
REG Foreign Key: CLIENT_ID, TXN_ID references CLIENTS
I select these three tables and choose generate classes and descriptors for selected tables. When the "Choose Relationships to generate" screen comes up, it only shows me the CLIENTS<-->TXNS relationship, but not the REG<-->CLIENTS relationship, even though the database foreign key constraints all look as though they've been defined in similar ways.
thanks for any help.

Hi Matt,
I'm not surprised that you have an issue with this. One bugbear I have with Gateway is that for some reason the designers don't think any context beyond the immediate preceding navigation node is important. They don't support this within the same service,so it's hardly likley to work in a service reference.
I may be wrong but I don't think GW is OData compliant in this respect. If I have the navigation path /blindservice/FromHereSet(1)/ToAPoints(22)/ToBPoints, it's rather restrictive to say I cannot see the initial key of '1' in the path when I am trying to resolve 'ToBPoints'. If that value - where I started - is key to the context, I have to know it.
Currently the only way to access this context is to embed the 'key history' in the intermediate entities, i.e. /blindservice/FromHereSet(1)/ToAPoints(1,22)/ToBPoints. In my view that is corrupting the URl to suit the limitations of the SAP OData implementation. What's even more confusing/frustrating is that the technical request context appears to be able to store the stacked navigation keys but doesn't make use of this design.
I feel your pain
Ron.

SQL Developer Data Modeler not drawing foreign key relationships

I'm having trouble with SQL Developer Data Modeler when I importa a DDL that has foreign keys. I export DDL files from SQL developer and choose various subsets of files. Sometimes Data Modeler will not recognize a foreign key if I include say a dozen files in the DDL file, but it will if I include just a few. Worse, even if the foreign key is recognized, sometimes it is not drawn in the Data Modeler and I have no way to make it be drawn. To be specific, I import a file containing the DDL for just two tables -- I see the foreign key! I import a file containing the DDL for a dozen tables including the two, I don't! Is there something I am not understanding about when Data Modeler will draw foreign keys or is the tool simply quite buggy?
Much thanks!

Hi Philip,
I believe I have isolated the problem. Apparently if a field is named "FOREIGN..." it interferes with the tool recognizing foreign keys. Try to import a DDL file containing the following text:
CREATE TABLE "SAMPLE"."SAMPLE_ONE"
(     "ID" VARCHAR2(255 CHAR) NOT NULL ENABLE,
     "VALUE" VARCHAR2(255 CHAR),
     PRIMARY KEY ("ID")
TABLESPACE "SAMPLE_DATA" ;
CREATE TABLE "SAMPLE"."SAMPLE_TWO"
(     "ID" VARCHAR2(255 CHAR) NOT NULL ENABLE,
     "FOREIGN_NAME" VARCHAR2(255 CHAR),
     PRIMARY KEY ("ID")
TABLESPACE "SAMPLE_DATA" ;
CREATE TABLE "SAMPLE"."SAMPLE_THREE"
(     "ID" VARCHAR2(255 CHAR) NOT NULL ENABLE,
     "VALUE" VARCHAR2(255 CHAR) NOT NULL ENABLE,
     "ALT_ID" VARCHAR2(255 CHAR),
     PRIMARY KEY ("ID")
TABLESPACE "SAMPLE_DATA" ENABLE,
     CONSTRAINT "FK6DF8294F2288190D" FOREIGN KEY ("ALT_ID")
     REFERENCES "SAMPLE"."SAMPLE_ONE" ("ID") ENABLE
TABLESPACE "SAMPLE_DATA" ;
You will discover the foreign key is not recognized or drawn! Now, if you swap the location of the third table (put it up first) everything works fine. This is how I discovered the problem, various subsets would work, others would not. To confirm the problem is with the field named "FOREIGN_NAME" use the DDL as specified above but change the first letter in the word "FOREIGN" to something else, and it will recognize the foreign key. Looks like a bug to me (took me about 4 hours to isolate this!). I am using Oracle SQL Developer Data Modeler version 2.0.0 Build 584.

Renaming Foreign Keys in the Relational Model

Hi,
I'm new to Data Modeler, we are using v 3.0.0.66.5 and Oracle 11g, and I'm trying to build a Logical and Relational model for a new application.
We always name our Primary Keys as ID, this is causing me a problem with my Foreign Keys names in the Relational Model, as they are showing as ID#. Is there a way to add the abbr. of the table to the Foreign Key?
Thanks in Advance
Sue

I always do that job using Naming Standard Templates. This sequence renames ALL FK COLUMNS for ALL TABLES only in RELATIONAL MODEL:
-Preferences > Data Modeler > Naming Standards > templates
-into the box "Column Foreign Key"
-Put something like that: {ref table}_{ref column}
-Then, go into your modeler tree, select the relational model, right click and use "Apply Naming Standards to Keys and Constraints"
-deselect all
-select the last option "Column Foreign Key"
-Go.
What if the names still collide? What if you want to do the job for some--but-not-ALL tables? forget the method above. A transformation script will do that.
You'll need some of these building blocks:
- table.getFKAssociations()
- keys.getRemoteTable().getAbbreviation()
- column.setName()
I'm novice to script coding, sorry I can't assemble a scripted solution right now.

Foreign key fields not getting populated in datacontrol palette for EJB app

Hi,
I am quite new to ADF and EJB.I developed a jdeveloper application with JSF and EJB tiers.(I am using jdeveloper 10.1.3.5)
For database the default HR database is used.I created the entities for the EMPLOYEES and DEPARTMENTS table.
I also created a session bean and a data control for the session bean.
I am having a JSF page that receives all the details of a new Employee and insert into database (i.e persistEntity)
But the Employees constructor from the Data control palette is not populating the MANAGERID and DEPARTMENTID fields which are
the foreign key constraints for the EMPLOYEES table and hence while trying to persist the entity
with the auto populated fields an error message is thrown.
If I used ADF BC instead of EJB then i could populate all the fields including MANAGERID and DEPARTMENTID.
Is it possible to have two text fields for Manager and Department in the jsf to insert the Employee details with EJB as the Model?.
If possible how do I bind the values of these fields to the Employees entity object in EJB.
Kindly need your insights on this.
Thanks,
Guna.

Hi,
How are you using MANAGER_ID and DEPARTMENT_ID fields, are they exposed as Long (or some other numeric type), or did you map them on the entity, something like this
@ManyToOne
private Employee manager; // this by default uses the column named MANAGER_ID
@ManyToOne
private Department department; // this by default uses the column named DEPARTMENT_ID
.... If you mapped them (which is the right way), when you create an employee you should set these attributes before persisting the entity, by using employee.setManager(manager) and employee.setDepartment(department). Then, the foreign keys get populated automatically by your persistence provider (Toplink).
If you are using data controls, it is a little different process to set the department and manager, but you should take a look at this tutorial http://www.oracle.com/technology/obe/obe11jdev/ps1/ejb/ejb.html , it will hopefully answer a lot of your questions.

Data Modeler - How to add foreign keys to physical model?

I imported few tables from data dictionary and tried to generate a DDL file. The DDL didn't include foreign keys for some reason. Then I noticed that the foreign keys are in the relational model but not in the physical model. How do I get those foreign keys to the physical model?

That's the place where I'm looking for the foreign keys in physical model. I noticed that in relational model the Generate check box of a foreign key was unchecked. When I checked it, the key appeared in the physical model. But why is it unchekced sometimes? This has happened only few times, usually the foreign keys do appear in the physical model. If I do something special during import, I don't know what it is...

SQL data modeller -- how to create 1 to 1 relationship foreign key ?

hi guys...
i got 2 tables..
table 1 - CFR
CFR_ID = primary key
table 2 - USER_PLAN
USER_ID = primary key
PLAN_ID,
CFR_ID = foreign key reference (table 1)
The business flows go like this..
insdie CFR table, it contain all records / transactions of a particular user/plan. everytime a new transaction occurs for a plan/user, a new CFR_ID / row will be generated.
after which, the newly generated CFR_ID for the new row , will be updated to the CFR_ID in USER_PLAN
Thus, there is always a 1 to 1 relationship between the 2 table regardless how many CFR_ID is generated for a particular USER_PLAN. as the CFR_ID in the USEr_plan table will always be the latest one generated inside the CFR table.
However, in the data modeller, i am unable to create such foreign key relationship... ANY idea how do i create a 1 on 1 foreign key relationship ? or there is no such way..
Thanks and Best Regards,
Noob

Hi philips,
Thanks for the wonderful reply..
Just to double comfirm with you,
even if i had set a unique constraint on CFR_ID(foreign key column), inside the relationship model, the relationship between the foreign key is still showing as a 1:m relationship right ?
just that a character 'U' will appear beside the CFR_ID column.
However the diagraphm is still showing a 1:M relationship.
is this correct ?
Regards,
Noob

Problem to insert id into the foreign key php/mysql

Hello all,
I'm having rouble to understand the process and there is no tutorial about my problem anywhere
I have two table:
Table 1 (member) with id, name, phone etc
Table2 (post) add_id, title, description, price, member_id
I got a form to post the add and I need to insert the id of table 1 into my table 2 member_id zone
Fisrt I did the recorset to get user id
$colname_rsMember = "-1";
if (isset($_SESSION['MM_Username'])) {
$colname_rsMember = $_SESSION['MM_Username'];
mysql_select_db($database_connect, $connect);
$query_rsMember = sprintf("SELECT * FROM member WHERE username='".$_SESSION['MM_Username']."'")or die(mysql_error());
$rsMember = mysql_query($query_rsMember, $connect) or die(mysql_error());
$row_rsMember = mysql_fetch_assoc($rsMember);
$totalRows_rsMember = mysql_num_rows($rsMember);
This part is working and I'm able to retreive info via echo just for testing
After this code I have my insert code
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form2")) {
$insertSQL = sprintf("INSERT INTO add (title, `description`, price, member_id) VALUES (%s, %s, %s, %s)",
                       GetSQLValueString($_POST['title'], "text"),
                       GetSQLValueString($_POST['description'], "text"),
                       GetSQLValueString($_POST['price'], "text"),
                       GetSQLValueString($_POST['member_id'], "int"));
mysql_select_db($database_connect, $connect);
$Result1 = mysql_query($insertSQL, $connect) or die(mysql_error());
$insertGoTo = "ok.php";
if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
header(sprintf("Location: %s", $insertGoTo));
Do I need to include hidden field in y form?
I'm having the same error message. Col member_id can't not be null
Any idea what I'm doing wrong?
Thank You!

When someone logs in, Dreamweaver creates a session variable called $_SESSION['MM_Username']. Use that session variable to create a recordset to get the user's ID, which can then be entered into the foreign key field of the child table.
Dreamweaver automatically puts the code for recordsets immediately above the DOCTYPE declaration, so you will need to move it above the code for the Insert Record server behavior. So, it needs to be in this order:
Recordset to get user ID
Insert Record for child table

Catch foreign key violations in the model, not the database
