Change of primary key?

• Change of primary key on the Table clears the other columns

  Preliminary info/Installation
  JDeveloper 11 g 11.1.1.6.0
  We have a table (object view or entity) that has 8 columns. The primary key is composed of 4 1 columns.
  The table is displayed in a page fragment.
  2 of the 4 non-primary key columns are LOV.
  All the 8 columns are needed.
  The table is editable including 2 of primary key columns.
  
  Question
  Assume that the table displays the 3 lines. If we change a rank 1 non-primary key column and a primary key in row 2 column, everything works well when we are committed to the database
  If, however, we first change a primary key column, then a primary key on a different line column, then the column/row primary key that changed us first, gets annihilated and the other columns LOV on this same line. The 2 columns that are not LOV keep data as it should. We then get a validation error because the required data are not present. All this happens before we try all commit to the database. If debug us and look the iterator, it has the old data in this document, before and after any performance on the binding.
  If we look at and update the data via the App Module, everything works well. We have tried to update the view, etc. through valueChangeListener also with no luck.

  If you change the primary key value, it should not be the primary key.

  This is true in the design of database relational regardless of how access you the data. In addition, EO don't like if you change the primary key value.

  Have you considered adding a surrogate key (use a sequence) and make your PK course a unique key?

  -Kamo

  Hi Kamo,

  What ID you want to update? The ID of the applicant (the master) or retail?
  Implement you referential integrity in your database (with restrictions)?
  If you do... you IMPOSSIBLE, simply, change the ID of the master. You would create better two identifiers: an 'external': visible to the user and can be changed. and an 'internal': used to unmodifiable and referential integrity.

  If you really, really, want to continue on your current path - mal - to solve your problem, you have the following options:
  -disable referential integrity and update the codes of the masters of master and detail using a copy of the original ID in your form (you will have two here: P70_ORG_APPLICATNTS_ID and P70_APPLICANTS_ID, the latter can be change) and change your pl/sql code.
  -Keep your referential integrity, but replace it with "DEFERRABLE" (validate on commit - then rethink your validation strategy, see the doc);
  -Keep your referential integrity, but change the code of your pl/sql: an update of an ID results in an insert (the master and details using the new ID) and a removal of the old stuff.

• change a composite primary key

  
  Hello

  I have a table that has a composite primary key with 3 columns (col1, col2, col3)

  Now I need to change the primary key (col1, col2, col4) remove composite col3 replace with col4

  col1	col2	COL3	COL4	col5
  1	one	x	p	DFD
  1	one	There	p	DFD
  1	one	z	p	SD
  1	one	m	p	amplifier
  1	one	n	p	Try

  There are thousands of records in the table in the format above. How to make this change?

  Thank you.

  In this case, you will need to establish that if the change to the primary key makes sense - if so, you'll have to remove some lines to remove duplicates. I think that if this requirement has been raised at a request of the company, they will (should) have indicated what lines need to be maintained.

  If it is not sensible, you will need to go to the one who asked for the change and get them to change their mind or tell you what to do with duplicate lines.

  Out of curiosity, why did you change the primary key?

• Complex validation of form on a primary key

  I have one that inserts/updates a table with a column 2 primary key (ticket_num, ticket_seq). Is there anyway to create a page validation feature that will prevent some users from the pk constraint violation and get the error ORA-00001 ugly.
  
  I think that I do not understand the syntax of the validation "SQL Expression".
  
  I would like to just find if the key already exists, but the following does not seem to catch it. I put the following in the expression of validation 1.
  
  (select count (*)
  of system_issue_timings
  where ticket_num =: P3_TICKET_NUM
  and ticket_seq =: P3_TICKET_SEQ) > 0

  The pl/sql with count (*) above will not work as select count (*) in... will never trigger no_data_found, it will result in zero in v_test.

  The other thing to watch for on this type of validation (that they are implemented as sql does not exist or as pl/sql return a Boolean or pl/sql to return to error), it is that if you do updates on this page, you must either:
  1 does not fire validation in update (assuming that you cannot change the primary key columns on the page), or
  2 specifically exclude the line updated validation research (for example using the rowid) otherwise it will comply with the condition and the validation fails.

  You probably want to use 'sql NOTexists' validation as it "passes if the query returns no row.":

  Select 1
  of system_issue_timings
  where ticket_num =: P3_TICKET_NUM
  and ticket_seq =: P3_TICKET_SEQ

• How can I make sure that changes in a primary key (in the parent table) would also appear directly in the FOREIGN KEY in the child table?

  Forgive my question. I am very new to Oracle.

  How can I make sure that changes in the key primary supplier_id (concerning the supplier table) would also appear directly in the FOREIGN KEY (supplier_id) in the products table?

  Is that not all the primary key and FOREIGN KEY on?

  My paintings:

  I created 2 tables and connect to apply in the data base referential integrity, as I learned.

  CREATE TABLE - parent provider

  (the numeric (10) of supplier_id not null,)

  supplier_name varchar2 (50) not null,

  Contact_Name varchar2 (50).

  CONSTRAINT supplier_pk PRIMARY KEY (supplier_id)

  );

  CREATE TABLE - child products

  (the numeric (10) of product_id not null,)

  supplier_id numeric (10) not null,

  CONSTRAINT fk_supplier

  FOREIGN KEY (supplier_id)

  REFERENCES beg (supplier_id)

  );

  I inserted the following text:

  INSERT INTO provider

  (supplier_id, supplier_name, contact_name)

  VALUES

  (5000, 'Apple', 'first name');

  I expect that the supplier_id (5000) to the provider of the table also appears in the products table under key supplier_id having the same value which is 5000. But this does not happen.

  How to get there?

  Thanks in advance!

  Hello

  What is a foreign key in Oracle?

  A foreign key is a way to ensure referential integrity in your Oracle database. A foreign key means that the values of a table must appear also in another table.

  Ok!??

  What is now the right way to implement referential integrity in your Oracle database that the values of a table must also be included in another table?

  A foreign key referential integrity indeed enfore in ensuring that the value in the child table must have a corresponding parent key (otherwise you will encounter an error, as evidenced by "SomeoneElse"). However, it will never automatically insert a row in the other table.

  If you are looking for a solution that automatically inserts a record in the other table, maybe you should go for triggers:

  See:

  • http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/triggers.htm#BABCIBBJ

• When I change a column is a primary key the associated non-unique index to become unique?

  So basically I already tried this and it shows me that the associated index is not unique.

  create table employees2 in select * from employees;

  create index emp_idx on employees2 (employee_id);

  ALTER employees2 table add primary key (employe_id) using index emp_idx;

  Select * from user_indexes where index-name = "EMP_IDX";

  I was wondering if I right assuming that when you change a column to a primary key or unique while using a given index that does not have the respective index become unique.

  The textbooks I use are sometimes a little hard to understand because of the wording, also, I want to just ask someone with a little more experience than me.

  Thank you.

  your test did give the correct answer: the index is not unique if it serves to bear a unique or primary key constraint. Indeed, it is one of the benefits of the use of no unique indexes in support of UK/PK constraints (since it allows to set the unusable index before to make bulk loads; and, of course, they have also some disadvantages - for example, they need an additional logical reading to reach a line).

  Column unique and not meaningful if you ever want to update. In the case of your example, you need to add an ID column in the intersection of book_author table. Honestly, I was so blown away (and pleasantly surprised) by the absence of rebuttal and the "thx" I advanced and set up an example of how I would define the book_author table:

  create table  book_author
     (id varchar2(32),
      book_id varchar2(32),
       author_id varchar2(32),
       modified_on     date,
       modified_by varchar2(255),
       constraint book_author_pk primary key (id),
       constraint book_auth_book_fk foreign key (book_id) references books(id),
       constraint book_auth_author_fk foreign key (author_id) references authors(id)
       )
  /
  
  create unique index book_author_uq on book_author (book_id,author_id)
  /
  
  create or replace trigger  biu_book_author before insert or update on book_author
  for each row
  begin
       if inserting then
            :new.id := sys_guid();

• Change/Remove primary parent

  Hello

  I need to change the primary parent on behalf of Microsoft family safety from one parent to another parent.

  How can this be accomplished?

  Thank you

  Arlo

  Hello

  To change the primary parent account that is associated with your child's account, you need to remove the primary parent. This will remove all restriction settings you requested to your child. After removing the primary parent, you will need to restore on behalf of the child under the new primary parent and the installer restriction again. To do this, please follow the steps below:

  1. go to https://familysafety.microsoft.com and sign up using the primary parent account.

  2. after accessing it, you will see the main page and a list of family members who are associated with the account main parent. Click manage the list of the members of the family , this option is next to make a family member, a parent.

  3. on this page, you can remove the Member who is under your account. You can also remove the primary parent by clicking on the checkbox next to the name of the main account.

  4. Once you have chosen, all members that are related to your account will be also included.

  5. click on the Remove button and confirm the operation.

  Once this has been done, you will have to restore on behalf of the child under the new primary parent account. To do this, please follow the steps below:

  Add/Re-adding a child (with a Microsoft account) for parental control in Windows 8

  In Windows 8, you can use accounts of Microsoft as a user. You just link the Microsoft e-mail account to the new standard user. Follow these steps:

  Note: Make sure that you have an internet connection to create a user with a Microsoft account.

  1. press Windows key on your keyboard to access the applications screen.

  2. tap create an account (you will be redirected to search application screen automatically).

  3. click on settings (second option with the gear icon).

  4. click on create an account on the selection to the left pane. (You may be prompted for access admin select an admin user, and then enter the administrator password).

  5. in the account management window, click Add a user account.

  6. you will be prompted to add a user, enter the Microsoft account email address in the text box then click on Next.

  7. check This is a child account? Turn on family safety for PC usage reports.

  8. click on Finish.

  After you create the child account, you can then go to the Family Safety website, log in using the parent account and then manage restrictions and control of your child options.

  Let us know the result later.

  Thank you.
