• 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.
  
  
  Thank you

• Problem with the primary key and indexes

  Hi all
  
  I'm looking a mess on one of our main tables.
  One of the developers here added an index on 3 columns in the table, thinking that it would speed up (not noticing that it had not a PK).
  
  Subsequently another developer has noticed there do not have a primary on key. So they added a touch of primry on the single column.
  
  The problem is that now the index created on 3 columns is bein used as the primary key index. As when the primary key is created a new index was not created.
  
  Is there anyway to get rid of this index/change it correct?
  
  This table is related to many many other tables, so when we tried to remove the index we could not due to the primary key and foreign key violations with other tables.
  
  Thanks in advance

  Oracle, as you found, is quite capable to use a column enformce multi index a single column primary key, as long as the pk column is the leader in the index. This should not cause performance issues for a search of PK and if the three indexed columns are often selected only may benefit from these types of queries.

  The only way to change that now, would be to drop all CF, drop and add the PK constraint and then add all the FK constraints. A long time and potentially dangerous (if you miss to add back of the FKs) endeavour. Certainly not worth the risk in my opinion.

• Numerical value in words (for the printing of cheque)

  Hi all
  
  To convert a numeric value into words (for the printing of the check), I created two functions in forms and reports 6i.

  Return (initcap (to_char (to_date (val, 'SSSSS'), 'SSSSSSP'))) End Function
  on the other
  return (»);
  end if;
  END;
  
  (2) function SPELLED_AMOUNTFormula returns the Char type is
  number of cents;
  c_str varchar2 (80);
  number of Val;
  Start

  Hello

  To spell out integers up to 5 373 484, use 'Jsp' instead of 'ssssssp '.

  TO_CHAR ( TO_DATE ( n     -- n = integer to be spelled
                , 'J'
              )
       , 'Jsp'          -- Case-sensitive
       )
  

  5373484 is the date of 31 December 9999, the last value DATE in Oracle. In Oracle 10.2, you can actually spell number a little higher by using the expression above, but I don't know why, and I wouldn't count on being able to do in the future versions.

  There is no need of INITCAP here. If the 2nd argument TO_CHAR is initcapped (as above), then the output will be, too.

  To spell even greater numbers, check out this page of Tom Kyte, which also includes languages other than English and the language of lakh-crore-Arabic-kharab.

  Hello

  I have a table that has columns as plant_name, business planner email id and identification of email resident engineer. Here, Plant_name is the primary key.

  Right now, I can go get plant in backing bean name, but I can't understand how business plan for extraction and identification of email of the engineer resident in this key primary-plant_name at the bean to support.

  Hi Sneha, you've written code for it

  you have found the current line and the primary key then this line, then why you not not using this same rank to get the other attributes?

  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

• Shape of the apex - how to get the primary key value manually?

  Hello
  
  Whenever I create form by using wizard Apex, he asks me to specify the trigger/sequence/pl/sql function to fill the primary key value.
  
  However, if I want to specify primary key myself (ie. undetermined generated automatically), how I can clarify that?
  
  Thanx

  Hello

  You mean by yourself: by hand or by a pl/sql?

  If you say by trigger, the system does not take on what number is sent. If you can give it "manually".

  May I ask what is the reason for this?

• How to get generated automatically the primary key to create procedure

  I have a service of physical data corresponding to a table named ACCOUNT. The primary key on the table is called ACCOUNT_ID. There's a trigger on the database which generates the primary key value and adds it during an insert. I would like to have this primary key value returned by the procedure of creation of physical data service. Any ideas on how this can be done? Thanks in advance.

  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.

  that is if he were CUSTOMER_ID, your client would look like this...

• creating a unique index of instaed of using the primary key index

  Hello
  
  I heard in a debate sometimes it is better to create a unique index on a column and use it instead of using the primary key index in oracle. I did not understand what that the reason propely.
  
  Can someone please help me in this topic if it is valid.
  
  Thanks in advance

  On the surface, which does not seem reasonable... Volume of the DML is irrelevent to determine which column is the primary key for a table.

  My wild speculation a bit at a reasonable time could someone do...

  If you use synthetic primary keys (i.e. the keys generated by sequence) and that your tables are subject to large volumes of inserts such as there is a danger that the block "to the right" will be the source of contention block and worry not about analysis of beach on the column, you can create a reverse on this column (unique or non-unique) key index before creating the primary key constraint and to indicate Oracle to use this existing index to respect the primary key constraint.

  Obviously, however, this involves a lot of assumptions to arrive at a reasonable point. There may well be another set of assumptions that could also lead to a valid argument. Or it could be a myth that someone has heard and just repeats.

• 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.

  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.

• 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.
