• Comparison of the data of several rows in a table - based on the primary key

  Currently I have a select statement that returns hundreds of records.  Each returned record is linked to A NUMBER of ORDER this order number has a recipe.  (a bit like a cooking recipe).  Each recipe has many records in the database related to this order number and records should be compared to records in a table that bind to a specific primary key...  (I have already developed the logic to isolate what PK I need).  If all these records that are returned by the select statement below does not match all the records containing PK in the table below, I need to get the next PK and compare all these recordings for select statements return.

  See below for a better understanding. Need a good example detailed on how to solve my problem here.

  Just to help you understand:

  Each element of the recipe is 3 parts (side, ref_des, part_number).  1 single recipe can have several parts (where the part_number), and each of these pieces should be placed on the lower side or top of the Board that is there "side" comes into play.  Same thing with Ref_Des.

  What is going on

  Select statement returns the RECIPE of ORDER NUMBER A.  There will be multiple records returned by this query.

  Select the Return statement:

  • Side
  • Ref_Des
  • Part_Number

  Example of return:

  B c17 75145-2

  T f14 89242-8

  B s12 45123-3

  etc,

  In general - what I need to do:

  There is a table called AUTO_RECIPE_DETAILS.  I take all of the records returned by the select query above and compare for each record in this table relating to the recipe 30319-000001.  30319-000001 a number of records.  It is the primary key for a whole recipe as seen above.  This primary key is bound the number of data records in this table.  The comparison is to see if all records under RECIPE_NAME 30319 -000001 match all the records returned by the select statement.

  IF IT DOES NOT MATCH: recover the following recipe in this table below 30319 -000002 and make the same comparison.
  

  Here's a perfect example of what the table looks like: (AUTO_RECIPE_DETAILS)

  
  

  RECIPE_NAME SIDE REF_DES PART_NUM

  -30319-000001 C16 87595-1 B

  -30319-000002           T B14 74150-4

  -30319-000001 T B14 34251-2          

  -30319-000001            T F24 84180-7

  -30319-000002 T B12 13710-8          

  
  

  
  

  It is the solution to my original question.  By this thread, it's the right answer and I hope this helps someone who is trying to compare two arrays element-by-element.  In the end, the advice given in this thread were correct and I will be using all of your suggestions and the scrapping of this.  Thank you everyone for your help though.

  NewRow row = lBinding.getCurrentRow ();

  String aamplant1 = (String) newRow.getAttribute ("Plant");

  String businessPalnner = (String) newRow.getAttribute ("business_planner"); Returns the value of the same line
  

  Engineer in String = (String) newRow.getAttribute ("engineer");

  
  

  OR if your condition is like that-

  you have a primary key field value, but you do not have the corresponding line, then you can get that line and it's attribute by using the primary key value

• Too many objects correspond to the primary key oracle.jbo.Key

  I get this error: Too many objects match the primary key oracle.jbo.Key when I tried to look for in a display object where the primary key is consists of more than one filed.

  Use case:

  In Jdeveloper 11.1.2.3 I Entity object called someTable this table has three fields A,B and C where the primary key is consist class towing A and B .

  I created different towing View object of someTable object enity that are someTableVO1 and someTableVO2 . Rated A in the view object somtableVO1 is a List Of Value(LOV) and the data are coming form filed A in the someTableVO2 .

  In application I have a search page that contains a drop-down list of registered A in somTableVO1 . Based on certain conditions, the drop-down list of the values in the list is not static. The value of the drop-down list is editable based on a select query run on someTableVO1 and it is based on the class thried C is NOT part of the primary key .

  The page displays the drop down menu with the correct values. But I have a ValeChangeListener method that will be activated whenever the user selects a value form the drop-down list.

  The problem is:

  The error Too many objects match the primary key is occur whenever I am executing this method.

  Support:

  I think the problem is with multiple fields for the primary key. of curse, there is an overlap in a part of the primary key (IE that paid A or B ) but the combination of A and B are always unique.

  Notes:

  1. I check the query by executing SQL Developer and it shows not all duplicate values.

  2 I don't attach code, because I think that the problem is not on (how to) this is (what to do).

  I hope that the idea is clear

  Problem solved.

  My goal was to show a summer that A form someTableVO1 as a list of value and I was trying to achieve by creating the list of value the same form Entity object . I understand that it was the wrong approach (correct me if I'm wrong). to achieve this in ADF technology, I have to do the following:

  1. Simply to drag and drop the view object from the Data Controls page.
  2. List of options appears asking how you want to display the view object (shape, chart, table, only one selection,...).

  3. Select Single Selection ->ADF one Selection

  4. Select the attributes that you want to show the user a list of values.

• implement the primary key on the field of forms

  Hello experts,
  
  I have a form with deptno single base table.
  dept_name and deptno. DEPTNO is a primary key in the database table.
  When I get the records, it prevents to insert the value that is duplicated in the deptno text box when I insert or update.
  
  the form I create a block with the base table, apply the primary key property of this Dept block. is Yes.
  then I put the key property primary deptno fields to yes.
  When I get duplicate records and then save, it prevents insertion but I want the following:
  
  I run the form, when I enter the first record, if it exists in the table can prevent to insert. also after the first record was inserted.
  If I insert to new deptno even into the next record, it must also prevent.
  
  Please help me.
  
  Thank you
  Yoann

  You have built your data forms to help block the "data block Wizard? If so, it already identified DEPTNO as the PK column. If it does not, or you have built your data manually block, you can open the palette property for the DEPTNO element and set the primary key property Yes. When this property is set on an element, the corresponding property of block, primary to apply key must also be set to yes. Please remember, however, that the Act of mark the DEPTNO as a PK does not 'Real time' checking for duplicates. Checking for duplicates occur when validation occurs. If you need a real-time duplicate check, you will need to write code to allow audits in double 'real time '.

  There are numrous examples in the forum to check duplicate in real-time as well as examples on the Internet. A search on Google for 'Check' the locker double shaped will give you lots of good examples.

• best method to update the primary key

  Can someone tell me the best possible method to update the primary key so that the foreign key is also updated.

  You're after a mechanism that lets you update the primary key sometimes on some lines, or did you just impossible, which means that you must update all the data because of some kind of change in the structural definition?

  If all you need is a rational method to change keys sometimes (and this isn't quite mortal sin that other posters have been suggesting) then recreate your foreign key as a constraint can be delayed may help.

  Oracle allows no you cascading updates automatically for primary keys, but if the foreign key is carried forward you can proceed as follows:

  set constraint {foreign key constraint name} deferred;
  update parent primary key;
  update child foreign key;
  set constraint {foreign key constraint name} immediate;

• Question about when Oracle checks the primary keys

  I had data as follows in a table:

  id1  id2
  ---- ----
     1    2
     3    1

  Id1 is the primary key and what I wanted to do was

  update this_table set id1 = id2 where id2 in (1,2);

  I was afraid that if he updated the line with id2 = 1 first of all, it would fail on a unique key constraint. Rather than take this chance I did it with two separate update statements. But I wondered, would he worked with an update? Are primary keys verified at the level of the line or at the level of the statement?

  as the primary key automatically obtained by ODSI leave a sequence in the DB and used during a procedure for creating

  Go to the design for the physical data service view

  Click the column which is filled from the sequence.

  In the Properties tab (bottom window), under general, for automatic numbering, click the 'Value' column, select sequence. You get a noise on some things have changed, just click OK. With AutoNumber = sequence setting, this column appears as optional (question mark).

  Just below that, for purpose of sequence, type the name of the sequence (you can also specify MYSCHEMA. In case the sequence SEQUENCE_NAME is under another schema).

  When you create objects SDO - leave the update vacuum column.

  BUT I also created a new page-> Form-> table for table "book_author" because I like to write numbers like id_book and id_author, change and remove them (so add relations between tables: book, book_author and author). During the creation of this page, I have chosen column 'id_book' as '1 primary key column' and 'id_author' as 'column primary key 2'. And on the Web site, I can't edit these fields.

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,

       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

  If the primary key values from DB sequence, you can follow this approach:

  Using the sequence of database in ADF - Souza Waslley Blog

  Oracle Fusion Middleware Technologies: ADF 11 G: generate the primary key sequence number

  Otherwise, instead of DB trigger, create the DB function that retrieves the value of the PK and call stored function in the overloaded method create() entity:
