[SOLVED] Show only primary key columns in database diagrams

Hi,
I'd like to create a database diagram with some tables hiding all the columns that aren't primary key or foreign key.
Currently the only way that I've found is right click on the column's name (in the table body visualized into the diagram) --> Hide selected shape
I've found the option that permits to visualize the constraint name and (optionally) the relative fields on the same row but what I'd like is something like:
<Table name>
<column_name> PK
<column_name> PK
<column_name> FK1
<column_name> FK2
Do you know a way to do this?
Many thanks
Best regards

Hi Tranen,
you can view the constraints and respective columns by setting the
Table Shape Properties in the Property Inspector.
Select (all) the tables on the Diagram you want
In the Property Inspector,under Constraints -Set the 'Show Constraint Columns' to 'True',
Set 'Show Constraints' to 'True' .
Constraints (PK,UK,FK,Check)
Also Set the 'Show Columns' option to 'False' .This will be under display options in the Property inspector.
This should modify the Table shape in the diagram as follows:
<Table name>
<PK> PKName:Column1,Column2
<UK>UKName:Column3
<FK>FKname:Column1
are you looking for the same?
Thanks.

  • No Primary Key Column was set. (UPD_NO_PK_SET)

    I'm trying to build an update record page that gets the primary key value passed from a dynamic edit selection. dynamic list is great..opens up to the update record page great...values filled in including the primary key...i can see the primary key value listed in the URL...but then i hit submit and I get:
    No Primary Key Column was set. (UPD_NO_PK_SET)
    I have seen this error posted a lot, but no concise solution..been working on this for days...Please please help..! i'm desperate!

    Ok, I'm confused....with
    <br />
    <br />// Load the KT_back class
    <br />require_once('includes/nxt/KT_back.php');
    <br />
    <br />removed all works great...the delete, the insert. When I do any of those desired functions, I do get back to the dynamic list page..however, I chose to edit say record 12 ..with only 10 showing per page so i'm on the second page...if i cancel..i jump back to record page one...Is that the functionality I'm losing?

  • No primary key column???

    Hello,
    I'm attempting to create an update form that connects to a mysql database. It pulls the information correctly, but it will not update...every time I hit update I get the following error(s):
    "No Primary Key Column was set. (UPD_NO_PK_SET)"
    ...for this error, I (and several others) tried messing with the update transaction...but nothing we tried worked. The primary key column appears to be set!
    The other error was:
    "# tNG_update.prepareSQL*
    * ERROR.Trigger_UpdatePassword_AddPassword
    * ERROR.Trigger_UpdatePassword_RemoveOldPassword"
    We'd like our users, once this project is finished, to be able to update not only their information, but their passwords as well. To begin, we manually assign their passwords.
    Uhh...other than that, I am currently using Developers Toolbox, Dreamweaver CS3, Windows XP, Dell computer.
    Any/all help is greatly appreciated.
    Thank you.

  • Updation of table records having 5-6 primary key columns.

    I have a table structure having 12 primary composite keys.I have created report + form on this table.My requirement is to update the table by using form items fields.I am taking help of url option on report attribute page of application to fetch data on form page when we click on edit link of report page.Now i am having two problems which are as follows:-
    (i)I am unable to update data as requirement is to update 5 to 6 primary fields along with other non primary keys.I tried to create Pl/SQL process which will run update query but this process is not updating values.Is there any way that i could fetch data direct from database table in query rather then taking item values.Is there any other workaround?
    (ii)One of the primary key column contains records which have ' , ' in them .For ex:- cluth,bearing.So when i get navigated to edit page i am only getting text displayed as clutch i.e. text before ',' is getting displayed in text field while comma and the text after this is not getting displayed in text field of form page.
    Any solutions will be very helpful.
    Thanks
    Abhi

    Hello Abhi,
    >> I am unable to update data as requirement is to update 5 to 6 primary fields along with other non primary keys
    APEX wizards support a composite PK with up to 2 segments only. For every other scenario, you’ll have to manually create your DML code.
    If you have control over your data model, I would listen very carefully to Andre advices. Using a single segment PK is the best practice way. If you can’t add PK to your table, it seems that you’ll have to write your own DML code. The Object Browser option of creating a Package with methods on database table(s) can be a great help.
    >> … I am taking help of url option … One of the primary key column contains records which have ' , ' in them …
    Using the f?p notation, to pass a comma in an item value, you should enclose the characters with backslashes. For example,
    \cluth,bearing\In your case, it should be the item/column notation.

    Heya,
    Looks like your DB is all setup correctly it must be the
    primary key in the transaction of the script.
    Make sure id is set as the primary key in your Update Record
    Form Wizard. You php code should look something like this:
    // Add columns
    $upd_contact->setTable("cvform");
    $upd_contact->addColumn("firstname", "STRING_TYPE",
    "POST", "firstname");
    $upd_contact->addColumn("lastname", "STRING_TYPE", "POST",
    "lastname");
    $upd_contact->addColumn("email", "STRING_TYPE", "POST",
    "email");
    $upd_contact->addColumn("message", "STRING_TYPE", "POST",
    "message");
    $upd_contact->addColumn("attachment", "FILE_TYPE",
    "FILES", "attachment");
    $upd_contact->addColumn("phonenumber", "STRING_TYPE",
    "POST", "phonenumber");
    $upd_contact->setPrimaryKey("id", "NUMERIC_TYPE", "VALUE",
    "id");
    // Execute all the registered transactions
    $tNGs->executeTransactions();
    You may have to post your script to see what the problem is.
    Most likely something not followed correctly in the tutorial. If
    you are able to post your php script as a text file then link to
    the file here with .txt extension I can take a look at it and see
    where the problem is. Make sure to remove any info that may
    compromise your database when providing your php script or contact
    me through my website and I can help you out off the forum.
    Hope that helps!

  • How to know primary key column name form a table name in sql query

    Suppose I only know the table name. How to get its primary key column name from the table name?
    Thanks

    Views don't have primary keys though their underlying tables might. You'd need to pick apart the view to determine where it's columns are coming from.
    You can select the text of the view in question from user_views.

  • Primary key column auto increment

    Hello,
    In my Azure SQL Database I noticed that weird thing is happening. I have table with primary key column with auto increment, and all works fine, on new insert that value automatically increment, but every now and then, that value, for no reason, increments
    for 1000.
    For instance i have in DB values in this order: 1, 2, 3, 4, 1001, 1002, 1003, 2004,  2005, 3001, 3002...
    Why is this happening? 

    Hello ,
    you can see this thread :
    http://stackoverflow.com/questions/17012339/windows-azure-sql-database-identity-auto-increment-column-skips-values
    It's seems that SQL Server work with sequence and block 1000 values. In the cloud, your SQL Azure Database can be move from one server to an other or restarted and so a new sequence is used. That's why you jump from 4 to 1001.

  • FillSchema picks too many primary key columns

    I don't know whether this is an ODP.NET error or a Microsoft error.
    Oracle9i Release 9.2.0.1.0
    ODP.NET 9.2.0.4
    .NET Framework 1.1
    Create a table with one primary key column and one unique column and name the primary key column like the unique column with the suffix "_ID":
    CREATE TABLE t_bib_uebertrag_kap(
    &nbsp kapazitaet_id NUMBER(8) NOT NULL
    &nbsp&nbsp CONSTRAINT pk_kapa primary key,
    &nbsp kapazitaet VARCHAR2(15) NOT NULL
    &nbsp&nbsp CONSTRAINT a_un_kapa unique,
    &nbsp geschwindigkeit NUMBER(12) NOT NULL,
    &nbsp bemerkung VARCHAR2(255)
    After calling FillSchema on this table the PrimaryKey property of the DataTable contains 2 columns: KAPAZITAET_ID and KAPAZITAET.
    The same happens with other tables and similar column names
    R. Lüthke

    Tony, I'm gonna find time to try this because I was thinking it probably would be a double check.
    BUT... Oracle is written in C, and I imagine the extra check as a simple if comparison for the new value versus a constant NULL value. Kind of like checking for end of string. It's already doing things like checking datatypes and that as it inserts data, and I don't think this additional check (if it even exists) would add any significant overhead.
    But unless I find a much larger performance hit than I expect, I'm gonna stick with creating the NOT NULL's explicitly. Good data modelling trumps small performance tricks for me.
    My main worry is if/when somebody removes the primary key constraint (such as the example above where they might do a CREATE TABLE x AS SELECT * FROM y). Or if the data model gets updated to where the primary key becomes just a unique key, then the NOT NULL goes away when it shouldn't. I don't like basic table and column properties changing.
    Okay.. test done. Ran about 31,000 records from dba_tables through an insert into two tables, both with primary keys and one with explicit NOT NULLs. No measurable difference in stats detected.
    With NOT NULL and PRIMARY KEY:
    call count cpu elapsed disk query current rows
    Parse 1 0.35 0.35 0 0 0 0
    Execute 1 1.88 1.83 0 24792 35887 30954
    Fetch 0 0.00 0.00 0 0 0 0
    total 2 2.24 2.18 0 24792 35887 30954
    Now with only PRIMARY KEY.
    call count cpu elapsed disk query current rows
    Parse 1 0.37 0.36 0 0 0 0
    Execute 1 1.87 1.83 0 24792 35887 30954

  • JPA: Attr ... mapped to a primary key column in the DB. Update not allowed.

    Let me just say that I posted a bug report for this here:
    https://glassfish.dev.java.net/issues/show_bug.cgi?id=3937
    But I'm also posting the info here, so that people who search on this forum may get some help:
    TopLink (both Essentials and 11g) has a problem with flushing entities
    containing a self-reference relationship. When flushing, the following exception
    occurs:
    Exception [TOPLINK-7251] (Oracle TopLink Essentials - 2.1 (Build b14-fcs
    (12/17/2007))): oracle.toplink.essentials.exceptions.ValidationException
    Exception Description: The attribute [id] of class [test.jpa.entities.Person] is
    mapped to a primary key column in the database. Updates are not allowed.
    No manual updates have been made to ANY primary key.
    What I'm doing is:
    1. I instantiate a new entity.
    2. I start a transaction
    3. I persist the new entity.
    4. I read an existing entity from the DB.
    5. I let the existing entity point to the new entity via the self-reference
    relationship.
    6. I flush the persistence context.
    7. I issue commit(), and the exception occurs. (I have provided the stack traces for various versions of TopLink below.)
    This is a clear bug.
    Here are some additional observations:
    1. Reproduced on the following versions of TopLink:
    1.1. Oracle TopLink Essentials - 2.0 (Build b58g-fcs (09/07/2007))
    1.2. Oracle TopLink Essentials - 2.1 (Build b14-fcs (12/17/2007))
    1.3. Oracle TopLink - 11g Technology Preview 3 (11.1.1.0.0) (Build 071214)
    2. Reproducible both on Java SE and Java EE. (I tested on Oracle Application Server)
    3. Reproducible with and without class weaving
    4. Reproducible regardless of whether the JPA annotations are on fields or on
    methods
    5. Reproducible regardless of whether "cascade={CascadeType.PERSIST}" is used or
    not.
    6. Reproducible regardless of the fetch type of the self-reference relationship
    (EAGER or LAZY).
    Also:
    1. Without flushing, the bug doesn't occur. That is, if I commit without
    flushing, it works.
    2. Without setting the self-reference relationship, the bug doesn't occur.
    This is an issue that appears when using BOTH self-reference relationship AND
    flushing.
    Best regards,
    Bisser
    The message was edited by bisser:
    Added info that the exception occurs "when I issue commit()" on step 7.

    I'm extremely surprised that you couldn't reproduce the error. It's reproduced each time when I run the Test Scenario that I described above.
    You could download a sample Eclipse project that reproduces the error from here: https://glassfish.dev.java.net/issues/show_bug.cgi?id=3937
    For the log below I used TopLink, version: Oracle TopLink Essentials - 2.0 (Build b58g-fcs (09/07/2007)).
    Could you, please, tell me what version you use and I will try the Test Case on it.
    Here's the FINEST log:

  • Switch the sequence of Primary Key Columns

    Hi MaxDB experts,
    As part of our product upgrade we've made a schema change to 10 of our database tables. Typically these tables contain about 5 million rows in them. The change involves switching the order of columns in the primary key (original order SampleTime, Id; new order would be Id, SampleTime). What's the quickest way to achieve this?
    So far I've tried the following approaches without much luck:
    1. Use the "alter table alter primary key (new seuqence of columns)". Takes an average of 1 hour per table.
    2. Copy original table content into another table with "insert into newTable (select * from existingTable)" command. Takes the same amount of time as #1
    3. Tried using "Export Table" option presented by the "loadercli". Unfortunately, exported data can not be imported to a table with a different schema (in our case changed primary key column sequence).
    What else can we try? Any advise / direction would be greatly appreciated. Thanks for your time.
    Sincerely,
    Sameer Apte

    Hi there,
    ok, I assume that you figured out that you like to have data entries belonging to a specific ID stored rather nearby than scattered around in the table by TIMESTAMP or that you have more queries that specify the ID but not the TIMESTAMP.
    Both would be good reasons to perform such a change.
    Concerning the speed: basically things won't get any faster than ALTER TABLE or INSERT (SELECT * FROM)...
    The ALTER TABLE approach would have the advantage to be transactional atomic and simple to use.
    The INSERT approach would enable the use of the PREFETCHING feature for the read-I/O on the source table.
    So if you're just focussing on speed, then I'd recommend to:
    setup a data cache that can hold both source and target tables im memory
    enable prefetching by setting the parameter READAHEAD_TABLE_THRESHOLD to say 128 (be aware that you've to use MaxDB 7.6.05 or higher, but not 7.7.x  for that!)
    After you've copied each table, make sure to create the secondary indexes one by one since otherwise the internal parallelism won't be used.
    regards,
    Lars
    p.s.
    it is possible to export/import into different schemas - it's even supported via DB Studio.
    Anyhow, it wouldn't make anything quicker for this case.

  • CDG-01141 ERROR: Module Component Table Usage ...  Table usage ... requires primary key column for referential integrity

    For some strange reason when I modified a form, (commented out some code in a when-window-activated trigger) I now get the following error.
    CDG-01141 ERROR: Module Component Table Usage GR1130A.CUSTOMER.GR_CUSTOMER.GC: Table usage GR_CUSTOMER requires primary key column for referential integrity
    I am sure this is not related to my change, but do not know what may have caused this or how to fix it.
    Anyone seen this error before? been able to fix it?
    Thanks!

    You know that Developer/Designer 6i is not certified for Windows 7, right? Also, your version is not the latest one, so you can try to install the latest patch set first.
    >Table usage GR_CUSTOMER requires primary key column for referential integrity
    Check if there is a PK in the table definition (not in the database, but in Designer).

  • Add another Primary key column problem

    Hi all
    I do not Add primary key in existing table .how it possiable
    say I have Existing Table
    EMPNO NUMBER(4), primary key
    ENAME VARCHAR2(10 BYTE),
    JOB VARCHAR2(9 BYTE),
    EMPSLNO VARCHAR2(10 BYTE)
    Now Add another Primary key column(EMPSLNO)
    my coding this
    ALTER TABLE EMP_TEST ADD (
    CONSTRAINT PK_EMP_TEST PRIMARY KEY (EMPSLNO))
    but error message
    Error on line 0
    ALTER TABLE EMP_TEST ADD (
    CONSTRAINT PK_EMP_TEST PRIMARY KEY (EMPSLNO))
    ORA-02260: table can have only one primary key

    ..Or, too much few information, wild guess, (composite index)
    Do this :
    ALTER TABLE <your_table> ADD (
         CONSTRAINT PK_mycode PRIMARY KEY (head_code,item_code )
              USING INDEX TABLESPACE tbls_index;

  • "Item Containing Primary Key Column Value" does not display records

    Hello,
    We are developing a new page where an "Automated Row Fetch" process is needed.
    With other pages we experienced no issues. But with a new one, when defining the value for the field “Item Containing Primary Key Column Value”, Apex displays no rows.
    As far as we know, Apex should display all the fields defined for the page. Is there any property which affects the fields visibility?
    The affected page has textarea and text fields.
    Thanks in advance.

    Hello,
    Sorry, we have already detected that the problem was at field definition.
    Fields should be defined as "Source Type: Database Column". They were wrong defined.
    Thanks.

  • OMPLUS retrieve table primary key column

    I'm trying to retrieve the primary key column associated with a table via OMBPLUS.
    The following command successfully returns the PK name
    OMB+> OMBRETRIEVE TABLE 'ODS_REGION' GET PRIMARY_KEY
    REGN_PKWhen I add the GET COLUMNS clause (as per API documentation), I'm still only getting the pk name.
    OMB+> OMBRETRIEVE TABLE 'ODS_REGION' GET PRIMARY_KEY GET COLUMNS
    REGN_PKAny suggestions on what I might be doing wrong?

    Worked it out. Syntaxt needed is:
    OMBRETRIEVE TABLE 'ODS_REGION' PRIMARY_KEY 'REGN_PK' GET COLUMNS
    (no GET between table name and PRIMARY_KEY clause)

  • Issue with getting sequance number from db in EO for a primary key column

    Hello Experts,
    we are working on ADf 11.1.1.2.
    we are facing issue with sequence number in our UAT instance.
    dev instance and sit instances did not gave any issues.
    We have one EO in that for one attribute we have given the value as
    new oracle.jbo.server.SequenceImpl("XXOZF_QA_CODE_S", object.getDBTransaction())).getSequenceNumber()
    in order to get the primary key column value from db sequance .
    <TransientExpression><![CDATA[(
    new oracle.jbo.server.SequenceImpl("XXOZF_QA_CODE_S", object.getDBTransaction())).getSequenceNumber()
    ]]></TransientExpression>
    now the issue is "I have incremented the sequence number through SQL plus from 10 to 20. And created a record on a VO which is based on above EO.
    But the sequence iam getting is 11 instead of 21."
    This is happening only in our uat instance all other instances are working fine.
    Can any one tell us how this frame work is still pointing tho the old sequnce number.
    regards
    Gayaz

    Also make sure that your sequence has NOCYCLE option.
    some thing like this:
    CREATE SEQUENCE test_seq
    START WITH 1
    INCREMENT BY 1
    NOCACHE
    NOCYCLE;
