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.

  • Update enrolled table which has 6 composite primary key

    Hi Everyone,
    I am trying to update a grade column in table called enrolled which has 6 composite primary key column including SID, TERMYEAR, FACCODE, DEPCODE, COURSENO, SECNO and 2 extra column including GRADE, IDD all of them are of type VARCHAR2 as describe below:
    To update this table I used the command below:
    UPDATE enrolled
    SET grade = :COURSE_BLOCK.GRADE_TEXT
    WHERE IID = :GLOBAL.logUserid
    AND SID = :COURSE_BLOCK.SID_TEXT
    AND FACCODE = :COURSE_BLOCK.FACULTY_TEXT
    AND DEPCODE = :COURSE_BLOCK.DEPARTMENT_TEXT
    AND COURSENO = :COURSE_BLOCK.COURSE_TEXT
    AND SECNO = :COURSE_BLOCK.SECTION_TEXT;
    Note: the :GLOBAL.logUserid is a global variable that I assigned the user id when the user log on to the application.
    When I run the application and fill out the form in order to update the table this doesn't update the table and if I use SQL*PLUS as well with the values that I use for the form to update the table I get message: o rows updated
    Can Someone help please?

    Here is the solution.
    The problem:
    The problem was that the enrolled table was designed in a way that a student can enrolled in the lecture(LEC type column) and Laboratory(LAB type column). When a student is given a grade, it is given a grade for the course 100 (eg: 03-60-100) this course has a lecture and lab. this course belong to the faculty code 03(science) department 60 (computer Science) so when a student register to a course, will register to a lecture and a lab but he will receive a grade for the course 100 lec in this case Oracle couldn't update the table because there was two column with course 100 for that particular student Id
    The solution:
    There are many solution I believe but my quickest solution is when a student register to the course by default is given a grade 'I' means Incomplete then when the instructor add the grade, he can just update a grade from incomplete to the final grade (eg A) now the code will be to get only the course 100 that has grade and discard that doesn't have grade this means that I need only to make sure that the WHERE Clause grade is not null shown below.
    UPDATE enrolled
    SET grade = BLOCK_NAME.FIELD_NAME
    WHERE grade IS NOY NULL
    AND IID = BLOCK_NAME.FIELD
    AND faccode = BLOCK_NAME.FIELD
    AND depcode = BLOCK_NAME.FIELD
    AND courseno= BLOCK_NAME.FIELD_NAME
    NAD secno = BLOCK_NAME.FIELD_NAME
    AND SID = BLOCK_NAME.FIELD_NAME

    Check if there is a PK in the table definition (not in the database, but in Designer).

  • Testing for unique records in a compound Primary Key table

    I have a table with 2 fields being primary keys. I want to write a sql script to check if there are duplicates.
    Here is what I have but not sure if this is working right. I have table with millions of records.
    SELECT COUNT(CASE WHEN A.AUNQ >1  THEN 1 ELSE NULL END)
    FROM
    SELECT (List_Cd + Account_Key) PK_ListAcc, COUNT(List_Cd) AUNQ

    Can someone help?
    thanks

    Yes, I agree. I am doing data profiling and testing all these tables. I am expecting that the results show me zero, however, if there were any problems with the settings, then I should get something. I think that the subquery is needed because if I used
    what you suggested above I will get the following:
    List_CD    Account_Key
    1                    a
    2                    b
    3                    c
    3                    C
    1                    a
    1                    a
    the results will be:
    List_CD    Account_Key    CountOFAccount_Key
    1                    a                       
    3
    3                    C                       
    2
    I now need to count that query results to get the total which should be 2
    do you agree? I am just trying to confirm that the sql script I listed will give me this result correctly.

  • How to update primary key column

    Hi,
    Can you suggest me best workaround/algorithm for below task:
    (Oracle 10g, Solaris OS.)
    Situation:
    Table P has primary key column "Code", child tables F1, F2, ..., F15 reference with foreign key column "P_Code" column "P.Code", and we don't know which of the child tables has data for particular "P.Code" value.
    Task:
    Change "P.Code" value from 100 to 200. So that result would be that record P[Code = 100] should be updated as:
    update P set
    Code = 200
    where Code = 100;And child tables column "P_Code" should be updated as:
    update F1, F2, .., F15 set
    P_code = 200
    where P_code = 100;The best solution would be that one very easily can repeat that task.

  • Adding primary key column in populated table

    Hi all,
    I am trying to add a column into a table which is already populated. The column which needs to be added has to be Primary Key.
    As expected, oracle popped up the error (ORA-01758) that, a NOT NULL column cannot be added unless the table is empty.
    One possibe way is to create a new temp table and then transfer all the current data...renaming the temp table later.
    Is there any other way to accomplish this task?
    Thanks

    Hello,
    As error suggested you cannot add a not null constraint on new column to table which is already populated. What else you can do beside you got fairly simple and quick idea of creating a temp table and moving data?
    You can add new column but null, update the column with the values and alter the table marking column as not null. But your idea of empty temp table is simple and quick one.
    CREATE TABLE my_objects
    AS
       SELECT 'my_new_column' my_new, owner
       FROM all_objects
       WHERE ROWNUM < 1;
    _Not Null_
    ALTER TABLE MY_OBJECTS
    MODIFY(MY_NEW  NOT NULL);
    _Primary key_
    ALTER TABLE MY_OBJECTS
    ADD CONSTRAINT MY_OBJECTS_PK
    PRIMARY KEY
    (MY_NEW);Regards

  • How to do hibernate mapping for table or view without a primary key

    Hi,
    Anyone knows how to do hibernate mapping for table or view without a primary key?
    thanks.
    cc

    or you can make all column primary key .Anybody seriously considering that as a good idea should understand the implications:
    1. this requires that each row be unique - that's a minor issue normally, but can be a significant problem in some cases
    2. in practically all databases, a primary key constraint creates a unique index - this has many implications:
    a) in most databases, the index stores a copy of the column data that is indexed - this suggestion therefore more than doubles the data storage required for the data
    b) whenever an indexed column is changed, the index has to be maintained - this suggestion then more than doubles the work that each UPDATE statement has to do, since both the table and the index have to be maintained for any UPDATE at all
    This might work OK for toy projects, but it doesn't scale well at all...

  • 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.

  • 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.

    EDIT: Updated the log because I found out that I had made a small change to the original Test Case while I was trying to find a workaround. The current log is produced by the EXACT Test Case I described in my previous posts.

  • VLD-0201:Table has more than one primary key

    hi
    i'm working with OWB 9.2,I was imported the table from database,when i validating that it is giving message:
    VLD-0201:Table has more than one primary key
    vld-0209:Duplicate unique key i.e:cust_acc and SYS_C00435 detected.
    Can i use this table and generate the mapping with out any errors?
    Any help will be very generate.

    Hi Ashok,
    I'm quite curious how you managed to get a table with 2 PK's.
    I tried it myself:
    =======================================================
    SQL>create table x(c1 number constraint pk1 primary key,c2 number constraint pk2 primary key, c3 date);
    create table x(c1 number constraint pk1 primary key,c2 number constraint pk2 primary key, c3 date)
    ERROR at line 1:
    ORA-02260: table can have only one primary key
    SQL>ed
    Wrote file afiedt.buf
    1* create table x(c1 number constraint uk1 unique,c2 number constraint uk2 unique, c3 date)
    SQL>/
    Table created.
    =====================================================
    As you can see, trying to create a table with more than 1 PK is impossible. With Unique Key, that IS possible (see second example).
    I don't expect mappings to function properly with such an error message.
    Is it possible for you to drop the table in the database, correct the definition of the table in OWB and then deploy that corrected version to the database?
    If on the other hand the table on the database is correct (i.e. has only one PK) then the import into OWB obviously did not go well and I'd suggest you drop the imported definition and try to import it again.
    Cheers, Patrick

  • Knowing the primary key columns of the given table

    Hi,
    How can I get the primary key columns of the given table?
    Regards,
    Sachin R.K.

    You can find the constraint_name from all_constraints/user_constraints for constraint_type = 'P' (which is the primary key constraint).
    And then see which columns are in for the constriant_name
    in all_cons_columns/user_cons_columns view.
    Below is the example
    select acc.column_name from
    all_cons_columns acc, all_constraints ac
    where acc.constraint_name = ac.constraint_name
    and acc.table_name = 'DEPT' AND acc.owner = 'SCOTT'
    and ac.constraint_type = 'P'
    Hope this helps

  • Update on primary key column

    Is it possible to update primary key column data by using MRU, i tried using the same but i encountered "mru internal routine error: ORA 20001" everytime i update.
    Or is there any workaround/suggestion

    Is it possible to update primary key column data by
    using MRU, i tried using the same but i encountered
    "mru internal routine error: ORA 20001" everytime i
    update.
    Or is there any workaround/suggestionTwo things.. One, what is your name, we are friendly group of folks here and would prefer to call you by name.
    Secondly, it is a preferred idea NOT to touch the generated primary key. Why would you need to update that value?
    Can you explain further what it is you are trying to do?
    Thanks!

    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)

  • Hi All,How2 delete a pkey for std table and add 2 new primary keys

    Hi All,
            How2 delete a pkey for std table and add 2 new primary key fields .Please provide me the required procedure .
    Thanks&Regards.
    Bharat.

    Hi Bharat,
    First thing is you need to have the access key to change any standard dictionary object/standard programs/ standard transactions.You may get this from your basis person after getting approval from your respective manager.But changing or modifying the standard object is not recommended, but if there is no alternate to meet the business requirement then we have to follow this way only.
    Next, you need to check whether this table's primary key is being used in any other table as foreing key or not. If there is, then you must remove this relation and then you can delete the unncessary primary key field from that table.Finally you can add the two new fields and set them as primary key, save, check for any errors and activate.
    Hope this helps.
    Please reward if useful.
    Thanks,
    Srinivasa
