ORDER/ALL in oracle sequences

Hello
I'm a single instance database running on Oracle 10.2.0.4.
If I have a sequence created using the ORDER clause, oracle will ensure that sequence numbers are still classified?
I understand that the sequences will have gaps. It is correct. I just want to know that it will be always ordered.

Is it really important if we use the COMMAND/ALL for unique instances? What happens if we give ALL?

I have read the oracle documentation, and I still have these questions.

Thank you
Delphine

Seems pretty clear in the documentation I looked upwards
http://docs.Oracle.com/CD/B19306_01/server.102/b14200/statements_6015.htm#SQLRF01314
"
ORDER specify in order to make sure that sequence numbers are generated in order of demand. This clause is useful if you use numbers in sequence as the timestamps. Guarantor of order is generally not important for sequences used to generate primary keys.

* ORDER is necessary only to guarantee ordered generation if you are using Oracle with Real Application Clusters database. If you are using exclusive mode, the sequence numbers are always generated in order.*

ALL specify ALL if you do not want to guarantee sequence numbers are generated in order of demand. It is the default value.
"

See you soon,.

  • Reset oracle sequence

    Hello world

    with the help of an ETL tool I'm migrating data in oracle database tables here I do not use oracle sequence. After the migration, I have to reset the sequence.

    ex: table: employee, name of the sequence: employee_id_seq

    initially:

    create sequences employee_id_seq

    start by increment of 1 by 1;

    data in the Employee table:

    employee_id ename

    --------               ---------

    1                    aa

    5                    bb

    6                    cc

    to restore order, I drop this sequence and recreate the sequence

    IE.,.

    employee_id_seq sequence of fall;

    Max (employee_id) here is 6 nextvalue is 7.

    create sequences employee_id_seq

    starts with 7 increment of 1;

    Select double employee_id_seq.nextval;

    nextval:

    --------

    7

    instead of delete and re-create the sequence any other method is there to reset the sequence.so, I want to create a dynamic script that will reset all of the sequences.

    Please advise on this.

    Thank you

  • I can do something that would cause all the new sequence files to have the same local variables?

    I would like to add local or drop some variables global to all the new sequence files I create. I was hoping that I could simply add the variable to the process template and make it appear whenever I created a new sequence or in any order who have used this process model, but it doesn't seem to work.

    Does anyone know a way to do what I'm doing?

    Thank you.

    Skeptic,

    If you use TestStand 4.0 and later versions, you can create a sequence model by adding a sequence selected in the models pane of the TestStand sequence editor.  You can then use this template to create all your future movies.  Once you configure the model you like you will be easy to reuse this sequence skeleton again.

  • API to create the purchase order in the Oracle applications?

    Hi all

    Can you please tell me the API to create the purchase order in the Oracle Applications.

    Please read the screenshot. There is no standard API to create a purchase order.  Better go to the open Interface to create the purchase order.

  • Close all files in sequence

    I need a sequence to close all files in sequence. I was hoping to find a method of engine as "CloseAllSequenceFiles". Unfortunately, this method does not exist. Any ideas on how I can accomplish this?

    Thank you

    Steve

    If you write your own UI using the teststand user interface controls you can apply or modify the implementation of ApplicationMgr.QueryCloseSequenceFile () event handler. There is no way to change the behavior of the sequence editor to do what you ask, I know.

    Hope this helps,

  • Export all tables, triggers, sequences, etc. of the APEX-hosted application.

    Hello

    I'm sure this has been asked in several variations before, but the answers I keep seeing in the forums offer "alternatives" that are not applicable to what I need to accomplish. While I am an employee of Oracle for a long time, I am only recently entered APEX developing and meeting some annoyingly situations of "newbie". Namely:

    I created a fairly complex application in the hosted APEX internal server. Now, I want to make a backup of all the objects of schema associated with my request. More important, I want to save the data in the tables that I will be performing manipulations of data on it prior to import into the new schema/database.

    I have to assume that there is a smart way to save the data in an application without having to:
    (a) manually export each table in an Excel or XML file.
    (b) manually having to write the same todo script
    (c) having a direct access to the database to use data pump or exp (not possible in the hosted environment)
    (d) application to another schema located in the space as a substitute for the backup of the copy.

    There MUST be a way to take a backup external/export data and objects related-databasebase APEX 4.0.2.00.07 which does not require the tedious manual methods or direct access to internal site hosted DB.

    Can anyone suggest the best option to perform this task?

    Guess it will do badly then. There is NO way unless you have access to the Sql developer or another product to download the data for all the tables and objects of database in one fatal shot.

    What we have are the following:

    You can have the apex generate a file of all your objects in database sql (sql workshop, utility, generate DDL) and this will build a sql file that will build all your Oracle database objects.

    After that, I'd suggest the utility to download data: unload sql workshop, utilities, data, data workshop. This will allo wyou'llill to download your data to a local workstation to the file xml, csv or txt format.

    SEQUENCE values always increase; but the gaps that may exist.

    post SQL & results that show the value of the sequence is less than the previous.

  • Order the dish/stacked sequence excecutes

    Normally, a flat structure to sequence in a loop for if Execute from left to the right until it reaches the end and then repeat the left right code as many times as the loop he tells too much.

    I want to be able to change the order / discreet in which the sequence loop around, so that my excecutes stacked in the 'Z' patter above sequence.  He needs to realize from left to right until it gets to the end, then bounce back (without repeating the last image) and run from right to left, until it hits the start frame, bounce again (without repeating the start frame), and executed from left to right to what he hits the last image, bounce back again once , etc etc etc, many times I have to say.

    Tips on how to achieve this?

    Forget the flat/stacked sequence diagram. They are only as a LAST resort.

  • Duplicate values generated by an Oracle sequence

    Hello

    Since a few days we are facing a weird problem in our application where the sequences seem to be generating duplicate values. Previously I thought is this is not possible, but now it seems to be a problem. Here are the details:

    Select * from v$ version;

    Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production

    PL/SQL Release 11.2.0.2.0 - Production

    CORE Production 11.2.0.2.0

    AMT for Linux: Version 11.2.0.2.0 - Production

    NLSRTL Version 11.2.0.2.0 - Production

    We use to insert it into a table column of the last sequence value that is of course the primary key of the table column. Today, we received a violation of unique constraint on the column of the primary key (which is driven by the sequence). Below is the last value of the PK column

    SELECT MAX(PCCURVEDETAILID) OF T_PC_CURVE_DETAILS;

    162636

    and below, was the last value in the sequence that has been less than the PK column

    SELECT S_PCCURVEDETAILS. NEXTVAL FROM DUAL;

    162631

    Then we checked the data of the user_sequences and found the next sequence value (LAST_NUMBER) to be 162645 which was greater than the current value of the sequence:

    Select * de user_sequences one a.sequence_name as "S_PCCURVEDETAILS" ;

    SEQUENCE_NAME

    MIN_VALUE

    MAX_VALUE

    INCREMENT_BY

    CYCLE_FLAG

    ORDER_FLAG

    LAST_NUMBER

    S_PCCURVEDETAILS

    1

    1E + 27

    1

    N

    N

    20

    162645

    I then modified the nocache sequence:

    change sequence S_PCCURVEDETAILS NoCache ;

    Select * de user_sequences one a.sequence_name as "S_PCCURVEDETAILS" ;

    SEQUENCE_NAME

    MIN_VALUE

    MAX_VALUE

    INCREMENT_BY

    CYCLE_FLAG

    ORDER_FLAG

    CACHE_SIZE

    0

    162633

    SELECT S_PCCURVEDETAILS. NEXTVAL FROM DUAL;

    162632

    We also face the same type of problem of violation of primary key to another sequence-driven table, a few days before.

    In our code, I also checked that the primary key in the table value is inserted using only the value of the sequence.

    Can anyone please suggest any reason this issue for

    Concerning

    Deepak

    I faced a similar problem about 3 years ago. Here's the story, suddenly in my UAT environment a job that inserts data in some tables began to throw exceptions of primary key violation. After investigation, I found that the sequence is x, but the primary key for the table is x + y. investigation more - DBA moved all production data without even notifying the application support team.

    Morale - pretty obvious

  • Question about Oracle sequences

    Please let me know if this question is not the subject of this forum and advise which forum I should post it. Thank you.

    We have a database 10g running on the AIX servers. A process of data loading was recently, and the development team is of the opinion that the question can be corrupted in the database sequence. This sequence is used to generate a unique primary key for writing in a table.

    Are there problems with 10g about the objects sequence database becomes corrupted? If so, is there a Metalink note published on a fix?

    Thank you all for a light on this topic.

    Hello

    Interview the max value of your column of tabale, in order to know the populeted of the maximum value of the sequence, compare it your currval in the sequence, and the maximum value for the column. If the values are not the same and the currval is lower than the max value, you will probably have the constraint violation, then increment the value of your sequence curr.

  • In Fox 15.0, how do I easily put my favorites in alpha order, all I see in the help is too old?

    HE wants to help can be easily put in Favorites in alphabetical order. I have all the files, just a long list of bookmarks. I am a novice in computerese, so I need very simple step by step instructions.

    I looked at the help section for this problem, but I found it was for older versions of Firefox, a lot of threads that have been closed and the references to the addons that are no longer available. I have Firefox 15.0 at present. Have a PC, not Mac and have Vista as an operating system.

    Things will be easier to find if you create some folders to categorize.

    To sort by alphabetical name, open the Bookmarks window with "Show all bookmarks" in the bookmarks menu, in the toolbar, choose views > sort > sort by name, then A > Z for ascending or Z > A to order descending. You can also organize the bookmarks in the order you want by dragging and dropping them in this window.

    I import my CD collection into itunes (Itunes game). EVERY CD I import if its popular or classic any tracks from the largest number (for example: import runway 27 of 27) when they are on track to itunes 27 is therefore now follow 1! I had to manually rearrange that tracks to edit playlist. I have hours of CD to import - can someone tell me if there is a work around? Ive looked at all the options and preferences - can't seem to find a setting for this.

    The sequence will never decide to use these skipped numbers? (by above example 6 to 20), if etc. of circumstance and is it possible to avoid it?

    But our PROD servers are running in exclusive mode, which means the sequence will keep producing in ascending order No?... I don't bother about the shortcomings.

    Yes there is no reason why it is not ordered if you are single-instance. But if you want to be sure, just put the ORDER in the sequence. There is no overload when you are single-instance.
