Oracle 10.2 g-lack of number sequences

We have identified some numbers were dropped generated by Oracle 10.2 g sequence features. Sequences were ongoing for most of the time, however, we witness a few gaps that occur randomly at times. This has happened in three of our tables. For an example that has only about 80 000 entries between sequences of ID from 800 000 to 900,000. Sequence jumped no permanently several times.

Is this a known problem or is there another way, that this can happen?

Code sequence:

create sequences CASE_SEQ
MinValue 1
MaxValue 999999999999999999999999999
Start with 966251
Increment 1
NoCache;

Look at the configuration of the cache of your sequences.

    Y at - it all another way to achieve the same result.

    Thanks in advance.

    concerning

    Hello

    CONNECT is the best way. It is not more complicated than the others, always at least as fast, sometimes much more quickly.

    If the output does not 1, then it might be a bit more efficient to add a constant, rather than generate many kinds you want:

    SELECT  LEVEL + 7     AS id
    FROM    dual
    CONNECT BY   LEVEL <= (20 - 8)
    ;
    

    In Oracle 8 (and earlier versions), this kind of CONNECT BY query did not work. People had to SELECT ROWNUM of a real table or view, for example object, which usually included at least 500 lines:

    SELECT  ROWNUM + 7   AS id
    FROM    all_objects
    WHERE   ROWNUM  <= (20 - 8)
    ;
    

    If there is no doubt that all_object had the same number of rows you need numbers, your could square of this:

    SELECT  ROWNUM + 7   AS id
    FROM    all_objects
    ,       all_objects
    WHERE   ROWNUM  <= (20 - 8)
    ;
    

    From Oracle 10, you can use model. Features XML to do this became available at the same time.
    From Oracle 11.2, you can use a recursive subquery in the WITH clause.

  • Number sequence for the value in the column group

    I need to create a sequnece number in a column from 5, and incrementing 5, based on the presenet values in the first column. If the value in the first column changes then the sequence would start with 5 and an increment of 5.

    for example: I want to generate the following output

    Cat_code Seq_No
    1001 5
    1001 10
    1001 15
    1001 20
    5 2001
    10 2001
    15, 2001
    3001 5
    10-3001
    4001 5
    4001 10
    4001 15
    4001 20
    5001 5
    6001 5
    5 7001
    7001 10
    7001 15
    7001 20
    7001-25

    So if the cat_code changes, the sequence number should still start at 5 and should be to generate the sequence number until the cat_code changes again.

    any help apreciated.

    Thank you
    Rahul

    Hi, Rahul,

    You can use the analytical function of the ROW_NUMEBR to generate the numbers, like this:

    SELECT       cat_code
    ,       5 * ROW_NUMBER () OVER ( PARTITION BY  cat_code
                                     ORDER BY        NULL
                         )       AS seq_no
    FROM       table_x
    ORDER BY  cat_code
    ,            seq_no
    ;
    

    You must use an ORDER byclause of Analytics when you call ROW_NUMBER. If you don't really care the order, so you can ORDER BY a constant, but you still need the analytical ORDER BY clause.

  • Oracle vs response column Format DOUBLE NUMBER/INTEGER

    Hello

    I noticed that the Oracle answers shows the testnumber which is 3144 as a double that is 3 144 but I did originally is a NUMBER (10 g) and is interpreted as a
    INT in the physical mapping layer (Administration OBI).
    Now, I wonder if I can change the format from 3 144 to display at 3144 on answers report directly. When I click on
    the format of the column, it seems that it allows me to enter some HTML.

    Any ideas?

    Thank you

    Hello

    What's a double, is not just OBIEE server using, like the thousands separator or am I missing something? This is controlled on the Format of data for the column tab in the query, you can ignore it and say do not use thousands separator.

    If you want to then that is the default value for this column, or the data type, you can use the record button in the bottom right of the pop-up window to save it as such.

    Kind regards

  • Can I be sequencing only when delivery on a shared system number?

    Hi all

    Can I be sequencing only when delivery on a shared system number?

    We currently share an oracle instance with two sets of books, the problem, it's that there are gaps in delivery numbers as the other entity sharing the delivery number sequencing. I would like to know in there is a way to divide the sequencing so that the two entities have their number of unique delivery without any gaps?

    Number of delivery is used as the invoice number when rasiing bills.

    Thank you very much

    Hello

    OM profile option: method of invoice numbering works at the level of the Site and there are two values by this profile options - delivery name and automatic.
    If you select site level as number of delivery of the invoice numbers will be based on delivery for all entities as mentioned above as having 8001, 8003 and B 8002.

    You can change the value of automatic profile and then delivery number and invoice number will be different and therefore you must set the transaction source numbering and sequencing of document for the respective transaction types.

    Kind regards

  • Change the number of sequence on a created cryptomap

    Hello

    I have a doubt regarding the sequence number of a crypto map.

    Now, I have a card encryption I'd like to do with lower priority (put a higher sequence number). There is currently 1 and and want to 3.

    To do this, I had to remove the card:

    No crypto map Internet_map0 1 1.1.1.1 ipsec-isakmp dynamic (it's a site 2 site vpn but with dynamic extrems)

    Next, I add a new card encryption with the desired sequence number:

    card crypto Internet_map0 3 ipsec-isakmp 1.1.1.1 Dynamics

    Is posible change the number sequence without first remove encryption card?

    Thanks to all and sorry for my English.

    Hello

    No there is no way to just change the sequence number, you will need to follow the procedure that you did the moving the map encryption for a different number of position or sequence.

  • Outgoing number comme.01 in oracle select number in mysql

    Ive got a metric schema in oracle, I work the size of backups and feed in a reporting tool.

    Ive created a link to mysql, created a view of backups which returns the size of the database.   It runs in mysql. I can see the size.  But the selection of the view in oracle to the link HS, the number going to comme.01.

    I tried the char conversion and adding text to it.  Same problem., works in mysql, custom in oracle.  Known issue?

    Select vw_backups in mysql

    I get

    = FULL backup

    size = 320G

    In oracle

    Select * from vw_backups@mysql_link

    = FULL backup

    size = .01G

    This is Mike's response.    My apologies to occupy your time on this one and your time is much appreciated.  the following link explains.  I would have thought that using the view with the pre-built data and sum could have returned successfully, but the loggin user privileges must dictate that can see the point of view.  a bit like a dba_objects view object in oracle.

    After you generate the query, you can use it in another schema, if the sequence is not available with this same name. After you have compiled successfully in other patterns, this sequence will start to give the starting number sequence number...

    Don't say unnecessary things. If you do not know the answer just better be quite.

    Why do you think that the answers of FlyingGuy was not necessary or that he did not know the answer.

    He was be truthful. Mathematically there is no difference between 1.0, 1.0000, 1.000000000000 etc.

    If the numbers are numbers so they must be stored as numbers. If a "user" must be able to see a number with a certain number of digits after the decimal point, so this has nothing to do with the way the data is stored on the database, but is rather a UI issue, such that the interface needs to format the number to a varchar2 for exhibition purposes (using for example TO_CHAR (numbercol ((, 'fm990.0000000000')) so that the correct number of digits after the decimal point are shown. A user cannot reasonably hope that if they enter 0 5 leak so when they see the data once again, it will have 5 0 leak or if they get 10 completed 0 it appears again with 10 end of 0. It's not how to work the numbers and not how they should be stored in the database.
