• Factor of clustering for the primary key Index

  Hi all
  
  I have cretead a new table with 1.7 million records with an index of primary key on ID (NUMBER)
  Number of blocks used is arnd 57 K.
  
  Factor value of clustering on the primary key index is 1.6 million.
  
  Could you please suggest what can be the reason for such a clustering factor high for the new table.

• Another syntax for creating primary key

  
  Hello
  
  
  I have a question about the right way to create primary keys.
  Earlier, we were on Oracle 9i and we have upgraded to Oracle 10 g. The question is when creating primary key is allowed to create the unique index and then to create the primary key constraint? or directly create the first key is better? or are there ways to both the same?
  
  
  for example:
  one way:
  
  
  SQL & gt; CONN u2/u2@db1
  Connected.
  SQL & gt; create table a (a1, b1 varchar2 number (2), the date c1);
  
  
  Table created.
  
  
  SQL & gt; create an index on a (a1) tablespace unique pk_a t1;
  
  
  The index is created.
  
  
  
  SQL & gt; ALTER table a Add (constraint primary key (a1) using index pk_a);
  
  
  Modified table.
  Another way:
  SQL & gt; CONN u1/u1@db1
  Connected.
  SQL & gt; create table a (a1, b1 varchar2 number (2), the date c1)
  2.
  
  
  Table created.
  
  
  SQL & gt;
  SQL & gt; ALTER table a Add (constraint primary key (a1) using index tablespace t1 pk_a)
  2.
  
  
  Modified table.
  Which of the two approach is better? or are they the same?
  
  
  Thank you

  Oracle will attempt to create the index to apply the constraint. Of course, it is certainly possible that the creation of the index will fail, but you would be just to move the point of failure of the CREATE INDEX statement to the ALTER TABLE statement, assuming that everything else is equal (that is, you create the index in the same tablespace, quotas and tablespace sizes are the same, permissions are not changed, etc.)

  It may be preferable in some contexts to create a non-unique index before the creation of the constraint and instruct Oracle to use the non-unique index to apply the constraint. If you decide in the future to make the primary key constraint can be delayed, for example, have a non-unique index allows you to make this change without having to (implicitly), drop and re-create the index. A separate CREATE INDEX statement also influences when you go to remove a constraint / index. If the index was created before the constraint, you can remove the constraint without affecting the index. If the index was created after the constraint, deleting the constraint implicitly removes the index. Normally, particularly with OLTP applications, this doesn't buy you much. Sometimes, however, there are ETL process benefiting from such things.

• DB sequence for the primary key

  Hello

  I have Table of key primary we use DB sequence in the database itself, for example if start a line (using sql client) DB without primary key sequence will do it for me, because of this trigger.

  (1) my doubt is if I generate A EO off this table I need to explicitly set db sequence for this attribute as this or no need to do this sequence bz DB does good for me!

  (new oracle.jbo.server.SequenceImpl("SEQ_NAME",adf.object.getDBTransaction())).getSequenceNumber()
  
  
  
  

  No, you use a db trigger all what you need to do is to define the type of the attribute DBSeqence. Then the framework will assign a negative value for the PK, which can and will be used as K until you commit the transaction. During this time the bed frame now generated correct sequence of relaxation and rights holders to PK all negative values of the line (and it's child row).

  Don't forget to check DBSequence attributes must have "Refresh on insert" together that it triggers the correct PK is read from the database after insertion.

  Do not use ' (new oracle.jbo.server.SequenceImpl ("SEQ_NAME", adf.object.getDBTransaction ()) .getSequenceNumber () ' attribute is the PK you use triggers to generate the sequence.

• How to delete several lines in the details Table with PRIMARY KEY = ("VID", "LINEITEM")?

  Mr President

  My worm Jdev is 12.2.1.

  I have master tables / details.

  I have 2 lines for each PRIMARY KEY = ("VID", "LINEITEM") as below in the Details table.

  

  Please help how to get a button on a jsf page to remove these two lines at a time.

  Concerning

  So, in your app (data model) module, you have a master relationship / typical retail:

  

  And the relationship between them is based on some ViewLink

  Now go to the ViewLink, relationship, accessor.

  Take a look at the Destination accessor.

  Generate accessor object to check and give a name Acessor

  

  Then go to the master VO, Java and Include accessor, the class generate a display line:

  

  Go to the class view Java generated line, you'll find a method with the name of the accessor of the previous step, in the form of:

  public RowIterator getYourDetails...or_whaterever_IsAccessorName..() {
  }
  

  Now, in the same Java class, write the following Java method:

  public void removeDetails(){
    RowIterator details = getYourDetails...or_whaterever_IsAccessorName..(); // it is RowIterator over all details
    Row r = details.first();
    while (r != null) {
        r.remove();
        r = details.next();
    }
  }
  

  This method on the Cilent export line Interface:

  

  Finally, pass the data controls and drop this operation on the form as a button...

• Trigger - use one to create primary key values

  I'm stuck on a simple use to do a TRIGGER that fires when you add new rows to a table and want to Developer SQL to add the primary key value.

  I seem to be able to relax, but it is not inserted the primary key but giving a SQL error: ORA-00947: not enough values.

  Here's what I have.

  CREATE TABLE HF_fishers

  (

  contact_id INT NOT NULL

  , name VARCHAR (25)

  , last_name VARCHAR (35)

  PRIMARY KEY (contact_id)

  );

  CREATE SEQUENCES HF_fishers_seq.

  Then I ran the following trigger:

  CREATE

  HF_fishers_seq_trigger RELAXATION

  BEFORE INSERTING

  ON HF_fishers

  FOR EACH LINE

  BEGIN

  IF (: new.contact_id IS NULL)

  THEN

  : NEW.contact_id: = NVL (: NEW.contact_id)

  HF_fishers_seq. NEXTVAL

  );

  END IF;

  END HF_fishers_seq_trigger;

  =============

  Then I executed the following SQL statement that gives the error.

  INSERT INTO HF_fishers VALUES('Jacob','Muller');

  But if I do everything is good except that it defeats the purpose of relaxation.

  INSERT INTO HF_fishers VALUES(1,'Jacob','Muller');

  MySQL has a nice 'AUTO_INCREMENT' command, but from what I understand in Oracle, I need to set up a trigger to automatically increment a column/cell, which in this case I use for the PRIMARY KEY.

  OK Jaramillo, I tried as you wrote, but what would be an INSERT statement correct?

  -After the code trigger of Jaramillo

  INSERT INTO HF_fishers (first_name, last_name) values ("Jesse", "Owens"); -I have the trigger but he made the mistake of duplicate key.

  INSERT INTO HF_fishers values (hf_fishers_seq.nextval, 'Jesse', "Owens");  -No trigger but get key duplicated,.

  INSERT INTO HF_fishers VALUES(:NEW_contact_id,'Jesse','Ownes'); -works without the trigger but the "get links" dialog box appears. So not much 'automatic' on this issue,.

  My mistake.  Here is the modified version of the trigger. I removed the CONDITIONAL clause and comes to be a part of the body of the trigger.

  So, I created the table, the sequence, the relaxation and ran the first two insert statements and it worked fine.  The third one you have invites SQL + or any tool you use to enter a value if she sees the ":" colon as a variable binding.  Colon only works in a trigger without asking for confirmation.

• How to fill out the table foreign key to the primary key form

  Hi all

  I'm stuck in this problem for 3 days, and I'm about to research and implement solutions on the internet.

  I have two tables

  create table prim (a number primary key, b varchar2 (100));

  create table CHILD (a number references (a) prim, varchar2 (100)) c;

  I created a page for PRIM table.

  = page name form on PRIM2

  I have manually two columns for the CHILD table to know

  P26_A_1 (for the primary key in the CHILD table)

  P26_C (for the column in the CHILD Table c)

  now when the user clicks on the button CREATE, a row must be inserted into the child table.

  I want to assign the P26_A to P26_A_1 during the validation process, so that a line must be inserted into the PRIM table as well as in the CHILD table.

  How to do this?

  I downloaded my application page in https://apex.oracle.com

  my workspace identifiers are inferior to

  name of the workspace = IMBERT

  username = demo

  password = demo

  kindly guide me.

  Thank you.

  Hello

  I created a new page (page 30) similar to your page and added the insertion of the child. It just check the page and code. It works now, when you insert the prim file is triggered a second trial which inserts the child record manually.

  On page 26 it was some sort of mistake, was easier to create a new as it was almost a standard form.

• How to refer to the primary key column of newly inserted rows of tabular form

  Hello

  I use APEX 4.2.0.00.27 with Oracle DB 11.2.0.3.0.

  I work with a tabular presentation wizard-created for insert and update a table using the integrated SRM process (sequence 10).  I'm trying to use a process of anonymous block of PL/SQL (sequence 30) to make another manipulation of table after the records were inserted or updated.  The manual process is associated with my tabular form and I use the variables of name of column binding in my program block.

  My (rsn_test) table has 3 columns: test_id (number), test_nbr (number), test_id2 (number).  Test_id column is identified as the primary key and the type of the source already exists a sequence rsn_test_seq.  Column test_id2 gets its default value 0 to a hidden page element.

  I would use my manual process for updating the value of the test_id2 column.  If it's 0 then I want to put the value of the column test_id.  If it is any other value, then it must remain at this value.  My logic works very well for an existing line, but I'm running into a problem with the newly added lines.  The new lines get inserted, but the test_id2 column remains the default value 0.  I can tell the debugger that the SRM process is triggered first and inserts the line, then my manual dealing with fires.  The problem seems to be that the connection variable: TEST_ID for the primary key column remains NULL after insertion.  I don't know how to get the value of the column test_id of my newly created line to use in my PL/SQL block to my update.

  Process of PL/SQL:

  DECLARE
  BEGIN
     :P7_SHOW := NULL;
     :P7_SHOW := NVL(:TEST_ID2,555) || ' and ' || NVL(:TEST_ID,787) || ' and ' || NVL(:TEST_NBR,9999);
     IF :TEST_ID2 = 0 AND :TEST_ID IS NOT NULL THEN
        UPDATE rsn_test
           SET test_id2 = :TEST_ID
         WHERE test_id = :TEST_ID;
     ELSE
        :TEST_ID2 := :TEST_ID2;
     END IF;
  END;

  Any suggestions?

  I have run tests on

  https://apex.Oracle.com/pls/apex/f?p=83488:1 demo/demo

  to see your problem.

  I have 2 solution for your problem.
  I add trial NOT tabular just usual block of PL/SQL

  	BEGIN
  	I'm IN (SELECT TEST_ID FROM RSN_TEST WHERE TEST_ID2 = 0)
  	LOOP
  	UPDATE RSN_TEST
  	SET test_id2 = TEST_ID
  	WHERE test_id = i.TEST_ID;
  	END LOOP;
  	END;

  and works very well, you can see in the sample.

  The other solution is to show new generated TEST_ID

  Adding a sequence as a default value for a column in a table field

  And to execute your procedure.

  I get how is with the good luck of time.

• 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.

• identification of composite primary keys

  Hi mates,
  
  I am trying to identify a unique value in a particular table, so then I tried to look for the primary key of the table constraints:
  
  11:54:07 brunos@vvp > select constraint_name, constraint_type, index_name, owner of dba_constraints where table_name = 'CARD_TRANSACTIONS ';
  
  OWNER CONSTRAINT_NAME, CONSTRAINT_TYPE INDEX_NAME
  ------------------------------ ------------------------------ --------------- ------------------------------
  VVP PK_CARD_TRANSACTIONS P PK_CARD_TRANSACTIONS
  
  
  Then I looked at dba_cons_columns:
  
  11:56:22 brunos@vvp > select * from dba_cons_columns where constraint_name = "PK_CARD_TRANSACTIONS";
  
  OWNER CONSTRAINT_NAME TABLE_NAME COLUMN_NAME POSITION
  ------------------------------ ------------------------------ ------------------------------ --------------------------------------------------

  VVP PK_CARD_TRANSACTIONS CARD_TRANSACTIONS METER 3
  VVP PK_CARD_TRANSACTIONS CARD_TRANSACTIONS 2 OPERATION
  VVP PK_CARD_TRANSACTIONS CARD_TRANSACTIONS STATE 1
  
  
  
  I understand that in a single table, we have only 1 PK only. It is a composite primary key? I expected to see 1 single value, and then he showed me 4.
  
  
  Thanks in advance.

  It is a Composite key, you can see the column in position to observe order in the Composite key.

• using a sequence as the primary key

  I use a sequence for the primary key of the database for dimensions (following Kimball methodology). In ODI, I define another unique key as principal. It will not let you select check null = true and therefore a sequence can serve as primary. Someone at - it something differently.

  You must follow the rules on the sequence

  If you use a sequence for the primary key for the database, and then identify another or several columns are coming from the source and use that you can only identify a row. Use these columns as your key to update.
