How to use FOLLOW-UP and COMPRESS the clause of the CREATE statement TABLE?

my oracle's 10g and the statement of create table below:

CREATE TABLE S005.q100

(

Q1 tank (1)

)

NOMONITORING;

After you create this table, I ask USER_TABLES, but the value of the follow-up column is YES.

I think there should be no how is? and also I have the same problem with the COMPRESS.

Thank you very much


Hello

Heap - organized tables are your usual routine tables. It is created using the BUNCH of the ORGANIZATION of the CREATE TABLE statement clause. This is the default value.

The other variant of this clause is ORGANIZATION INDEX, which means that you will create an organized Index of Table. In other words, it is a table that is stored in a B-tree, like an index.

You also have an EXTERNAL BODY, which means that you will create an external table. Here is generally flat files outside of the database that you can order the database to see tabular to use SQL (read only) against. You will also need the settings on how the data are presented on the file, so that your database knows which column will match that of the data.

The COMPRESS on 10G is known as the "basic compression" and it works on ordinary table segment blocks, which are organized by a bunch of tables.

  • Satellite A210 - 16G (PSAELE) - how to use 4 GB and update the BIOS?

    Hello! I hope someone can answer a few questions for me.

    First of all is: How can I turn on my laptop to use all the 4 GB of RAM? OS is Win Vista Ultimate 32-bit with Service Pack 2. Now Vista all show the 4 GB of RAM, but don't use it. I activated the EAP in Vista, but still nothing. As I saw, I need to turn it on too memory remapping in BIOS but there is no option (my BIOS is ver.1.70).

    The second question relates to the BIOS. Because my version is 1.70 and there are more recent version 2.00; I get benefits if I update to BIOS? Someone has updated to version 2.00? And there are more options in the BIOS after update to version 2.00 (for example the memory remapping or a similar option)?
    I'm a little afraid to update BIOS, because sometimes my Toshiba freezes, and I would not hang during the update of the BIOS.

    And the final question is there any changelog to the BIOS? So I can see what is added and changed, and what's new in the new version of the BIOS. Because I could not find anywhere.

    Thanks for the responses to come.

    Hello!

    (1) you can use the entire 4 GB of RAM on a 32 bit OS. It is a due limitation of 32-bit technology. Windows Vista with Service Pack 2 may recognize the full 4 GB of RAM but not use it, more than 3.2 g.
    Here you can find more information about this limitation:
    http://APS2.toshiba-tro.de/KB0/TSB82022E0000R01.htm

    (2) about BIOS updated I can tell only must be made only if you have problems with the laptop. A BIOS update should never be done just for fun, because it of still a little risky. In the worst case, you can destroy the ROM module or complete motherboard.
    Update the BIOS doesn't normally contain new features or options. It s bug just setting. In addition it can t solve the problem with 4 GB of RAM and Vista 32 bit if you think that ;)
    If your laptop does not have 100% stable you shouldn't t update because it s too risky. Before the update, you should try to solve the problem of gel.

    (3) If a change log is available you can find it on the Toshiba site. If you can t find, there isn t available.
    That s all about this.

    I hope I could help a bit.

    Good bye

  • How to use FTP Client and manage the table in BB with JDE

    I'm a newbie to BB development. I have an application in mind, it is a simple ordering application. BB users can send order information to an ftp server. The BB will have some paintings as a customer table and the Order Details table (the two have only a few records). Since cannot use the Services of SDM BlackBerry because the license fees. I'll use JDE to develop the application.  Here are my questions:

    1. What is the best way to manage the tables (read/write)?  RMS, or embedded database (which one?)
    2. is there any ftp client in JDE, api can be used to send data to an ftp server?

    Thanks for help.
    PJ

    The exact figures for RMS sizes are available in this article:

    What is - size restrictions when you use the RecordStore
    Article number: DB-00656
    http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800451/800724/What_Is...

    So that your information is correct, in 4.6 or later, the per application limit went up to 512 KB.  I don't know if there is a limit on a single record in a record store. We must be careful of the terminology here, it's RecordStore or RMS - is not in BlackBerry terms anyway, PersistentStore (see next).

    The BlackBerry offers two other ways to store data.

    The first and most commonly used are called PersistentStore, and it is an a storage mechanism for objects, I am not aware of any restrictions, other than the memory of the device, about the size of an object that can be stored in PersistentStore.  The advantage with PersistentStore, is that you just persist an object helps you, rather than having to convert it to bytes (serialize) before storing and converting new (him deserialize) after reading it back.

    The second way is to write data using the FileConnection API, and you can for example use this to write data to the SD card in the device.

    EFF and PersistentStore use the flash memory in the device.  You don't have to manage yourself.  You treat all that identical objects, the BlackBerry operating system very cleverly manages to bring your items in RAM and save them in Flash, so you don't have to worry about the type of storage you have.

    I hope this helps.

  • How to use a directory and change the sizes of jpg

    Maybe I'm in the weeds here, but I'm looking to use an action to walk all files in a directory and for all jpg files to reduce the size of the longest side at certain age % and then save the file in a nother directory.  So I need to be able to:

    for all the files in the named directory {}

    look at the file type

    If {.jpg

    Look at the size of the image

    apply % next longest retractable age

    Save the file

    }

    }

    Simple stuff, but I don't know if stock allows me to do the walkor playback of the type or the criterion of size, etc.

    So if possible, can someone tell me the orders for action I need - or - another way to do this.

    Thank you

    Take a look at this video tutorial on a custom by Benjamin Root action. If you don't care no watermark, you can omit that.

    In this way, it should open correctly in CS6, and the original document is unscathed.

    How to use windows search to search the contents of a bunch of files with random names / extensions? Plain txt files say 1,000 with random name of file extensions?

    You can always search within those, but you need to add extensions to the file system so that it knows to look inside these files.  You said that you have a lot, so it's perhaps tedious.  Here's How to search within several types of files.

    One thing you could try is rather to make a copy of this file, rename all the files to the same extension (even an extension false for example something.bill) and perform your search on this band.  Just an idea.

  • How to use setViewportBounds (Bounds value) to the ScrollPane?

    How to use setViewportBounds (Bounds value) to the ScrollPane? This method is, visually, what for? I tried to put a specific Bounds.minY to have a precise scrolling in the axis Y in vain. I use the setVvalue() method to scroll, but it is not convenient to exactly locate a position in the coordinates of the node content listed in the scroll pane.

    The viewportBounds are the limits of the viewport (i.e., the visible part of the content) in the scrolling pane itself, if I understand correctly. The way to access programmatically is by setting the vValue property.

    I have not tried, but if you do something like

    scrollPane.setVmin(0);
    DoubleBinding vmax = new DoubleBinding() {
         { super.bind(scrollPane.viewportBounds(), content.heightProperty()); }
         @Override
         public double computeValue() {
            return content.getHeight() - scrollPane.getViewportBounds().getHeight() ;
         }
    };
    scrollPane.vmaxProperty().bind(vmax);
    

    to configure your component to scroll, then you can call setVvalue (...) and just pass a location of coordinates for your content node. This assumes that your content node is a region or a control; you will have to perhaps a little logic in the method computeValue() to deal with the cases where the display window is greater than the additional content.

  • The use of sequence and generate the number in a table that has data

    Hello

    There is a custom table that has a column Rowid (NULL).
    This table already has 10 k with rowid as null lines, now the user asks me to enter a unique number for the Rowid.
    I created a sequence, but don't know how to use this sequence and generate numbers for the Rowid.

    Could you suggest.

    Thank you.

    "rowid" is an oracle reserved word and should be avoided. Perhaps "Rowid" between quotes or something.

    Here's how to "fill" a column by a sequence:

    SQL> create table t (id number, value varchar2(100));
    
    Table created.
    
    SQL> insert into t (value) select object_name from all_objects where rownum <= 10000;
    
    10000 rows created.
    
    SQL> create sequence idgen_sequence;
    
    Sequence created.
    
    SQL> update t set id = idgen_sequence.nextval;
    
    10000 rows updated.
    

    Given that the sequence was used all the 'id's will be unique.

    Thank you, Jefferson. You addressed the issue beautifully and delightfully complete.

  • How can I get a name of table 1, column A, if column B is a negative number and insert the names of table 2?

    How can I get a name of table 1, column A, if column B is a negative number and insert the names of table 2?

    What is the formula?

    You can do this with a column of "index" in table 1, as this assistance:

    The formula in C2, filled to the bottom:

    IF (B =<>

    That increments a counter each time that it finds a negative number in column B.

    In the second table, you can retrieve a list of negative values in this way:

    The formula in A2, filled to the bottom:

    = INDEX (array 1::A, CORRESPONDENCE (LINE (−1, Table 1::C), 0))

    It takes the line number, the formula is activated, subtracts 1 to the header line and look up the result in the column of table 1 C.  If it finds a match, it feeds the line number to the INDEX page with retrieves the value of the column of table 1A.

    To hide the red triangles of signage wrap the IFERROR formula, like this:

    = SIERREUR (INDEX (table 1::A, CORRESPONDENCE (LINE (−1, Table 1::C), 0)),"")

    Of course, you can also simply filter on column B without the need to set up a column from another table or index.

  • seems that I bought the wrong size stock photo because it shows the low resolution 20 x 30... How can I return it and get the right kind of photo?

    How can I return it and get the right size stock photo that actually works to post 20 x 30

    Hi Debbie,.

    Once that the photos were allowed, they cannot be removed or not allowed.

    Thus, you must make sure that the image you need for your projects. You can also check the size of the images before their approval.

    Hope that answers your question.
