Missing primary key column in created form?

Please help. I am a newbie in apex.
When i create form and view it later I am missing primary key column.
HOw to make it show?
Thanks in advance.

Hi,
While creating the form based on a table/view, what have you chosen to populate the primary key value? Existing Triggers or Existing Sequences or Custom PL/SQL function?
Can you check for the Get PK pl/sql process in the page processing region of the related form page? If that function is missing then do the following steps to create the same,
Step 1 : Create a new pl/sql process.
Step 2 : Choose the Process Point as, On Submit After Computations and Validations.
Step 3 : Write the following block,
declare
  function get_pk return varchar2
  is
  begin
    for c1 in (select TEST_SEQ.nextval next_val
               from dual) -- Create a new sequence for your requirement.
    loop
        return c1.next_val;
    end loop;
  end;
begin
  :P3_TEST := get_pk;  -- Change the item name for your page.
end;After doing all the above, try executing the page.

  • Primary key in adf create form

    Hi,
    I want to insert data to a table which has primary key. I have created a sequnece wich produces the uniq key number and trigger for before insert wich puts the number.
    Even I have trigger , when I commit a create form (I have drop create form on jsf page from datacontrol palette and put a commit button ) I get an error which says that this field is required. Is there something I missed??Anyone who has an idea??
    Please I need any kind o fhelp...
    Thank you very very much in advance
    Regards

    Thanks a lot, it worked. But it doesnt work if I have mandatory columns.Even I put some values when I commit I get the message that the value of this columns are required. Then I did something else. I changed back the primary key column from DBsequence to NUMBER and from the page's bean I put default vallue for it. In this case it works. Which way I should prefer? Is there something else that I have to add when I set the type to DBSequence?
    Thanks in advance

  • Ability to auto create a primary key column while creating an entity ?

    Product : oracle data modeler ( 3.0.0.665 32 bit version ) on windows XP Professional , : Target DB Oracle 11GR2
    I am new to Mozilla Rhino. Is it feasible to have a mechanism where in the primary key column name would be auto generated when the entity ( name ) is just created for the first time, and it has no columns defined yet . For e.g. one could create an entity named vendor , and after the table name is typed in, a column vendor identifier,of type numeric , is to be auto created. This mechanism should work even if the entity name changes, and the primary key is in format {tablename}_id , but it should not , if the primary key was manually set in later and is not in the expected format.

    I created this script (1) for adding an ID column (using a specific domain) to all supertype entities that do not already have an ID attribute, and a script (2) for adding primary key constraints to all ID attributes.
    - Marc de Oliveira
    Script 1:
    entities = model.getEntitySet().toArray();
    domain = model.getDesign().getDomainSet().getByName('Integer DIS Domain');
    for (var e = 0; e<entities.length;e++)
    entity = entities[e];
    if (entity.getHierarchicalParent()==null)
    attributes = entity.getAttributes().toArray(); // find existing attributes
    IDattribute = null;
    for (var a = 0; a<attributes.length; a++) // look for an ID attribute
    if (attributes[a].getName()=="ID") { IDattribute = attributes[a]; }
    if (IDattribute==null) // if an ID attribute was not found...
    IDattribute = entity.createAttribute(); // create a new ID attribute
    IDattribute.setName("ID");
    IDattribute.setDomain(domain);
    entity.moveToIndex(IDattribute,0); // move ID attribute to top
    Script 2:
    entities = model.getEntitySet().toArray();
    for (var e = 0; e<entities.length;e++)
    entity = entities[e];
    attributes = entity.getAttributes().toArray(); // find existing attributes
    IDattribute = null;
    for (var a = 0; a<attributes.length; a++) // look for an ID attribute
    if (attributes[a].getName()=="ID") { IDattribute = attributes[a];}
    if (IDattribute!=null) // if an ID attribute was found...
    key = entity.createCandidateKey(); // Create a key
    key.add(IDattribute); // Add the ID attribute to the key
    key.setPK(true); // Define the key as a primary key
    PKName = entity.getName().replace(" ","_")+"_PK";
    key.setName(PKName); // Define the key as a primary key
    entity.setPK(key); // workaround for bug...

  • How can I hide primary key column in BC4J form

    I have populated a primary key with dbsequence and how can I hide it on the form. It is populated in the DB by a trigger.

    I have populated a primary key with dbsequence and how can I hide it on the form. It is populated in the DB by a trigger. To hide it, edit the attribute using attribute-editor that you bring up by double-clicking on the attribute in the "StructurePane" .
    Then go to control-hints panel and mark the attribute setting for Display = Hide.
    Then UI wizards will not add the attribute into generated panels.
    However once you have UI generated, this hint is no more used.

  • Primary key column in manual tabular form

    I am creating a manual tabular form and am unsure what to do for my primary key column. When I do this with the wizard, I'm allowed to specifiy a Primary Key Source Type and the Primary Key Source (my sequence). Is there a way to do this in a manual tabular form?
    I'm creating the column with the call 'wwv_flow_item.display_and_save(2,hours_id) hours_id' but when I edit the 'Tabular Form Element' section, I don't have the Primary Key fields anywhere to edit...only Reference Table Owner, Reference Table/Column Name. Where can I specify the sequence?
    Thanks,
    Janel

    In the process ApplyMRD, try specifying the 'Secondary Key Column' in the section 'Source: Multi Row Update and Delete' to the second key column in the tabular form.
    I haven't tested this with your situation, but worth a shot.

  • Hi  cant see the primary key column in master detail  form

    I have a master detail form .In the first master form i am unable to see the primary key
    Now the form is built completley and i also will like to see the primary key column visible in master report
    If i had set the primary key as rowid then i could have seen the primary key ..
    Now i can see the pencil icon (The eidt row pencil icon) instead of the actual primary key column . .which is a number data..
    I will like that too be visible ..Can any one guide what should i do for this..

  • 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.

  • How do I let user enter a primary key value on a form

    I'm creating my first APEX application. I have a simple table called HOSTS with 2 columns HOSTNAME and IP_ADDRESS. HOSTNAME is the primary key for the table. HOSTNAME is a perfectly acceptable primary key and I don’t wish to create an additional column to be populated by a sequence.
    What are my options for creating a form on the table without using "Existing trigger", "Custom PL/SQL function" or "Existing Sequence" to populate the primary key column, i.e. HOSTNAME, so that the user can enter a value for the primary key?
    Any assistance greatly appreciated.

    The debate about natural keys versus surrogate keys
    will no doubt continue with advocates for both sides.
    However there is also a difference between
    'making your life easier' for APEX development and
    'making your life more difficult' by having to
    analyse, implement and deploy a surrogate key only
    approach to an existing database which employs both
    natural keys and surrogate keys.
    hould we be forced to change the database design
    because a development tool does not cater for natural
    primary keys?The application development product is TRYING to save you from shooting yourself in the foot. The idea is to separate the primary key from being accessed by the user or ANY carbon based unit.. The key is mainly used by the system to join and lookup data rows, not for people to change whenever they decide that the key is WRONG.
    Think about this, if you use Last Name as a key in your system (a bad idea to begin with since this is NOT a unique id when you have two Smiths). When a person needs to change this because Jimmy Smith is NOT the only Smith working for Acme Toys, you have to cascade that change through all the child tables related to the main person table.
    If instead you use a system generated key, no change will be required since the key has NO relation to the data other than it represents a pointer to that row of data.
    Works for me, since I do not want to write all the supporting code when APEX builds it for 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

    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!

  • 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
    Fetch 0 0.00 0.00 0 0 0 0
    total 2 2.24 2.19 0 24792 35887 30954

  • 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.
