question of partition

Hello

my doubt is whether can create a partition on a column of table just by taking a few tank column.

that is, suppose that in the column, value comes as 105, but I want to score on only 10 (substr ('column_val', 1, 2)).

can do everything an answer if we can do it like this.

Thank you

Vipin Kumar Rai

Before 11 g to partition a table the Partition key must exist physically in the table. Starting from 11 g you can use the virtual column to define a partition key. A virtual column may be some such expression as described by you.

  • Question about partitions on Equium A100-027

    Hi all!

    I'm new to the forum but have been hidden for a while and he thought at the time that I said "Hello".

    This and the fact that I have a question about my laptop Satellite A100-027.
    The hard drive on my laptop seems to be divided into three partitions = Vista (c) / data (E :) / WinRE (d) with the WinRE (D :) is quite small but others, quite large.))

    My C drive is up to 3 that GB free with about 35 GB of free data (E :) is possible to merge these two to give me a big drive? And if so, how?
    Please excuse my ignorance, but it seems impossible to me to "get my head around" this thing hard drive and would split the a large hard drive.

    Any help would be greatly appreciated and once again, Hello to all.

    Hello

    As the user previous already said, you can manage HARD drive partitions in disk management settings.

    If you n t want to have a data partition (e) then you can try to delete it in disk management.
    Then you can add this empty space of the HARD drive for other partitions on the HARD drive.

    But note; the empty space will be placed at the end of the HARD drive. I don't know if your C partition is placed as a second HARD drive partition, but if so, then it should be no problem to add empty space to partition C (System) of m.

  • Two Questions of Partition

    I want to change the drive letter of a couple of scores. For the current configuration, see: http://paulrittman.com/CompMng.png.

    I want to do is make my score of documents (currently F), d.

    It is, the letter D is currently assigned to a backup partition. When I right click on the partition in the center pane higher in my screenshot, I don't get anything in the context menu, but a link to a help file. When I click on partition F, however, I don't see the option to change the drive letter assigned.

    In addition, if you look in the upper middle pane, you will see two instances of the recovery partition (D).

    So my two questions:

    (1) is there a way I can change the drive letter of the partition recoery? Or even if I can him, isn't it advised?

    (2) the presence of two lines to my D recovery partition in this upper middle pane means anything it either bad - such as, if I ever need, will be miss BIOS Windows / connection and refuses to start or restore from this partition?

  • Questions of partition T43 (1871) hidden

    I was given an old T43 (1871), on which I could install Windows 7 and, surprisingly, have almost everything works pretty well (even if there are two elements in the device manager that do not seem to be cooperating). Regardless, it works well (for an old machine Pentium-M with 2 GB of RAM).

    Here's my question:

    There is a hidden partition which, if I understand correctly, contains information of the recovery, to make the machine in the way it was when it came from the factory. As this machine comes with XP and I now have Win7, is it safe to erase and delete this partition? Or is there something in this partition that has something to do with the blue Access IBM button that seems to be the equivalent after pressing the DELETE key in a generic Windows PC? Just in case I am confused the issue, let me rephrase the question. Relying on the Access IBM button above the keyboard works correctly (to choose a different disk or enter the BIOS) if I remove the area of the hidden partition (assuming I want to restore the T43 in its delivered state of XP?

    If I have fubar was the question, please let me know and I'll try to clarify. Thank you very much.

    Barry

    Welcome to the forum!

    It is perfectly safe to nuke the recovery partition you have no intention to run XP on this T43.

    Once the recovery partition is removed, the blue button will offer you start options and nothing else.

  • question of partition dividing Acer e1 - 572 g

    Hello everyone I bought an acer e1 - 572 g with a 750HDD.

    My question is can I divide the c partition into two halves without effect on the hidden restore partition?

    or won't be able to recover the factory default after?

    Thank you

    Yes, that's right, this happened to me a few years back with Vista, resumption of the factory was stuck when I left the partitions in the alteration of the State but when switched back to the original set upward (IE, as it was when I bought the laptop) recovery plant is completed without a hitch.

  • Formatting for sale - question of partition Inspiron 9100

    Hi all

    I looked through forums and the difficulty in finding the exact answer to my question.

    I will sell my Inspiron 9100 this week - I have no CD of restoration, as it has the partition hidden for formatting/reinstalling.  However, I read that this type of format may not be to wipe my hard drive, and for data protection issues should I use external software to remove all my information on the drive - my questions so are:

    What utilities to wipe the hard drive are free and easy to use?

    These utilities will remove the partition to restore the system to factory State?

    Of course, my main concern here is the 2nd question!

    Thank you very much for any help you can offer, I'm a little trouble with this kind of things, and with the laptop sold Tuesday, I'm desperate!

  • Question on Partition 'DATA' on the Satellite X 200 - 20 s

    Hi, firstly it is great that toshiba has this forum directly from the page of the manufacturer. I wonder what is on the partition of DATA from my laptop. The 200 X 20 s comes with two 160 GB HARD drive. One is divided into two 73 GB. I would like to install linus on the DATA which is empty. What is the purpose of it?

    I guess that the intent of the parititon of 'DATA' is to store data on it. Sound very logical in my opinion. Since you have a HDD recovery you should check first if this DATA partition is not the recovery of HARD drive partition. I think that the best thing to do before installing linux, create a recovery disk with the "Recovery Disc creator and then install your linux system.

    On linux, I have an interesting link for you:

    Hope you find your machine here.

  • Question of partition: partition and narrower than the disk space

    Hi, I have a big problem with OS X El Capitan 10.11.3.

    I used to have a Windows partition with bootcamp which I deleted via bootcamp, but it crashed.

    I lost all my partitions and even os x. I have therefore started in recovery mode and launched disk utility, I could not create a partition OS X 90Go on my 120 GB SSD, and I installed OS X on it. Once installed, I have tried to maximize the size of the partition in disk utility to the actual size of the SSD, but it wouldn't work. Worse still, it actually shows my OS X partition a 60 GB instead of 90... (we also say that change log has not been activated, I allowed him but nothing happened)

    How can I make my OS X partition as big as my SSD?

    Here are some pictures of the utility disc and occupied disk space.

    Try to launch the Boot Camp again to see if it will delete the partition. It acts like it doesn't have.

  • Satellite M60-170: Question on partition Express Media Player

    Hello

    I want to install Linux on a Satellite M60-170 (thus transforming part of NTFS partitions in other systems of files) without erasing/reformatting the Partition of Express built-in Media Player.

    I don't see 2 Partitions using Partition Magic 8, predefined Microsoft (NTFS) 37 GB each on the hard drive of 80 GB.
    I read on the forum that the Express Media Player is a T88 204 MB partition system.
    How to see where this partition is located or do you know where it should be?

    (Partition Magic reported an error right after the end of the 1st partition, sector 7815624; the 2nd NTFS(1st extended) begins at the 78156288 sector: I expect that the Express media Player is a 2nd primary partition located between 2 NTFS partitions, but I would be sure.)

    Thank you in advance,
    Bruno

    Hello

    I m not 100% sure, but I think that the Media Express hidden partition is placed at the end of the hard drive.
    I found information that the disk HARD should at least 150-200 MB of free space must be available.
    This free space must be on the end of the HARD drive and there must be unallocated.
    To get these free places on party products 3rd HARD drive must be used.

    You should also consult this useful document on the Express Media Player installation.

  • Question about partitions on Portege M700

    Hello

    I was wondering why my M700 Vista Ultimate came with 3 partitions.
    EISA, the part. C: System, a primary partition without name of 5 GB.

    The EISA should be the recovery partition, but what is the last for?

    I can delete to create a different partitioning scheme?

    THX.

    EISA is not the recovery partition and this partition Go 1.5 belongs to Vista. The name of this partition is also WinRE (Windows Recovery das). If you want to know more about this please use Google. You will find many interesting documents on this subject.

    Portege 700 unknown to me but 5 GB partition can be partitions for recovery that contains the recovery image. For older models of laptops the recovery image was always recorded on DVD, which means that the recovery image is big enough. I presume that it is between 3 and 5 GB.

    You have already created recovery DVD? If this is not the case, try to do. Tell me if you need two blank DVD media.

  • Question of Partition of hard drive recovery Vista

    I tried to repair my Vista OS using the recovery hard disk partition.  It did not work.  Instead, my laptop (dell inspiron 1545) continue to boot normally without doing a repair.  So I guess something is wrong with my operating system may not be able to access the recovery partition, or the recovery partition is corrupted.  If I do a complete vista reinstall with the OEM that came with my laptop disks, this recovery partition will always be there or it will disappear?  If it is there, I will be able to use it in the future to repair my computer if necessary, or will it be an empty recovery partition?

    Hello

    The recovery discs are back to exactly how you bought new

    The recovery Partition is not not to make repairs; It is to reinstall the operating system configuration (new State); do the same thing as the recovery disks.

    It's the opinion of Dell on how to use their Vista recovery Partition;

    "Restore your software Computer´s factory settings."

    http://support.Dell.com/support/topics/global.aspx/support/KCS/document?c=us&l=en&s=Gen&docid=DSN_336966&isLegacy=true

    Dell also has diagnostic software to solve computer problems:

    "How to run Dell 32-bit Diagnostics utility"

  • The age old Question of Partition...

    I got my Dell XPS 8700 for about two weeks, just long enough to get me into a bit of trouble.

    It came with a 2 TB hard drive, and of course, the space was almost all in one huge partition where Windows 7 Pro is installed.  I managed to shrink this partition to 200 GB (still 70% unused).  I also have a "Shared Data" of 10 GB volume.

    Disk management are the following:

    No 39MB (healthy, Partition OEM)

    24,67 GB NTFS RECOVERY (in good health, the Partition Active, primary system)

    OS 195,32 Go (healthy, boot, page file, Crash Dump, primary Partition)

    SHARED DATA 10,00 GB (healthy and logical Partition)

    Go 1632,99 without label unallocated

    =====

    I thought primary topic vs logical at all when I created SHARED DATA, but obviously was Windows Disk Manager. I tried to create a partition in the unallocated space and told me that I already had four primaries.

    So now, I have four primary partitions allocated and wants more logical partitions.  The Extended Partition that contains my logic is full.  Can I resize simply upward to gain space to create more logical partitions, or the logic will increase when I resize?  Does anyone have a step to a procedure of time that I can use?

    Thank you

  • Three questions on partitioning

    RDBMS version: 11.2.0.4

    OS: RHEL 6.4

    Type of environment: OLTP

    ++++++++++++++++++++++++++

    We have a large non partitioned table with 4 billion documents and is 3 TB in size.

    We want to partition this table so that it can be easily maintained. We prefer partitioning on a daily basis.

    We are required by law to retain data only for 15 days. So, let's drop these scores after 15 days.

    The existing table using tablespaceA.

    We want to score range (with INTERVAL) by the CREATED_DATE column. We want to move the existing data to the great partition of base called PRE_2016 as shown below.

    About, it would look like

    create the table order_dtl

    (

    number of order_id,

    billable_flg not null char (1 car)

    complmntry_flg not null char (1 car)

    order_quantity_luom not null varchar2 (20)

    .

    .

    .

    CREATED_DATE timestamp (6)

    )

    partition by range (created_date)

    interval (numtodsinterval(1,'DAY'))

    (

    PRE_2016 PARTITION VALUES LOWER THAN (TO_DATE (DECEMBER 31, 2015 23:59:59 ',' HH24:MI:SS DD-MON-YYYY ',' NLS_CALENDAR = GREGORIAN '))

    )

    IN-STORE (tablespaceA, tablespaceB, tablespaceC);

    Question1. No idea how long it will take to make Exchange a partitiong using redefining online? Just a rough estimate would be.

    Question2. In the existing table, we have data for the years 2013, 2014 and 2015. When you create the partitioned table mentioned above, is there a way that we could divide the base for the years 2015 and 2013,2014 partition?

    Question3. After redefining online, I have to manually create the constraints and indexes. Right?

    None of the suggestions/recommendations are welcome

    For daily partitions, I understand that clues them are better.

    Better to do what? Consider CHOOSING. You expect to have 15 partitions. Search by index of a local index no prefixes will be so fifteen index partitions, which will have about 15 times so that the search for an overall index of research. Indeed, you may find that the optimizer favors the scans. Are you sure that you want to partition at all? Partitioning can make sense if you have hundreds or thousands of scores, but just fifteen years? Why bother?

  • a question on partition

    I have the table that stores the daily bills that a company receives invoices.

    INVOICE_DT INVOICE_AMT CUST_NO INVOICE_NO

    daily invoices received for the report which is good

    1 billing date partition table

    2 monthly partition table

    Hello

    Either may be good.

    If you do a query that doesn't need that look at a calendar day, then partitioning by calendar day is exactly what you want.  If you were only to partitioning per calendar month, then you'd have about 30 times more in the score you need, but that can always be good.

    Like anything else, the answer to all situations depends on the details of this situation.

  • Question of partition size

    Oracle Version: 11.2.0.2
    Operating system platform: Solaris 10

    EXPLAIN the plan of output (or any other method) to a SQL, how can we say that the size of Partition is not the case?

    What can be done to ensure that the optimizer will only look at the relevant partition (not the entire table) for the records it seeks?

    How to determine if the size of Partition was used

    If Oracle uses partition size is reflected in the plan of execution of a statement, in the table of the plan for the instruction of the EXPLAIN PLAN or in the shared SQL area.

    The partition size information are reflected in the columns of the PSTART (PARTITION_START) and PSTOP (PARTITION_STOP) plan. For series instructions, information of pruning is also reflected in the columns OPTIONS and OPERATION.
