When you insert a blob field which way is correct? (Transferred to another forum: jdbc)

When we prepare a paper for the insertion of a row that contains the blob column. Is what sense this correct? And what is the difference?

1 preparestatement.setblob(parameter number, blob type object)

2 Preparestatement.setblob(parameter number, inputstream type object)

Anyone know?

As suggested, you should post this question in the JDBC forum.

Java Database Connectivity (JDBC)

Before posting it see Chapter 14, "Working with LOBs and BFILE" in the JDBC Developer's Guide

http://docs.Oracle.com/CD/B28359_01/Java.111/b31224/oralob.htm

This chapter shows how to do what you are trying to do you and has the code example.

Also for a character BLOB series are obsolete, since there is NO conversion is performed.

With LOBs, you will need to first obtain a locator. Do you it by introducing a row first, and then ask Oracle returns the Locator for the LOB column. Then you can transfer the data using this index.

The doc explain it.

  • What happens when you insert/modify/delete a row in a table - concepts

    I am trying to understand the below concepts regarding the internal concepts (for example, undo and redo)

    (1) what is happening in the database when you insert a row in a table?

    (2) what is happening in the database when you update a row in a table?

    (3) what is happening in the database when you remove one line in the table?

    I have read the oracle documentation and mistook the redo and undo behavior. It would be great if someone explains the concept in a simple way.  I'm a novice programmer to understand database concepts. Any help would be much appreciated.

    INSERTIONS and deletions are handled the same way.  The cancellation of an INSERT is a DELETE.   The cancellation of a REMOVAL is an INSERT.

    Therefore, the generation 'Cancel' for INSERTION is less than that of a DELETION (because the cancellation of a DELETION is to reinsert the line - the value of each column in the row must be captured in the undo).

    If restore you an INSERT, then Oracle executes effectively a DELETE tablename WHERE rowid =... rowid_that_was_inserted.  A cancellation for an INSERTION is 'rapid '.

    If restore you a DELETION, then Oracle executes effectively an INSERT tablename values (col1, col2, coln).  The cancellation of a DELETION takes more time because Oracle would have to re-enter the values.

    Remember that Oracle also captures the redo to undo it (and do it again for the price drop if you do a restore).

  • "this file does not have a program associated with it" message when you insert the sd card

    When I insert an SD card into my computer, I get a message that says f:\ that this file does not have a program associated with it... I know I can set default programs with the types of files in the Control Panel, but how do you recognize what to do when I insert an SD card in the computer?

    The problem is caused by the automatic game changing options, this can sometimes happen when you install a new program, but they can easily be changed back. Click 'start' at the bottom left, go into "default programs" on the right side of the list (under computer / doc/images etc.) select "Change AutoPlay settings.
    You will find prob some of the sections had the new auto run program, just edit those you want (or all) "ask me every time", you will find that when you insert an sd card, you get the options normal download, copy, etc. as usual.

  • images dialog box is empty when you insert the memory card

    This is after you have inserted a card high capacity in the player, which hung the memory slot.  Now just insert a regular memory card, the dialog box appears, but there is nothing in it.

    Sorry if the info seems confused but maybe the
    answer is here somewhere.

    FWIW... There used a similar problem with a Sony memory
    Stick... the solution is to insert the stick into the drive and
    Restart the computer... somehow this would reset the
    stick.  I don't know if it will work for you.

    You may also check your AutoPlay settings...
    If you insert the card and go to... Start / my computer...
    and right-click on the drive letter for the location of in the map is...
    choose... Properties / AutoPlay tab...

    Choose... Mixed content...
    Tick... Select an action to perform
    On the left, click on the default button / apply / OK.

    Give it a try...

    It is possible that your media player is not compatible
    with the SDHC technology. The best is maybe to buy
    an external drive that is compatible SDHC or download
    Unit photo using a USB cable.

    Regarding the card... have regular SD, you tried to manually
    Download the pictures?

    If you connect the device to your PC via a USB cable, turn
    on the camera... then go to... Start / my computer... it may be
    listed as a drive letter...

    If_yes_right click on the drive letter and select... Explorer or
    Open... This should display the directory of the memory card.
    You can copy and paste or drag and drop the files from there to a
    folder on your hard drive.

    (The same steps work if you have a media player...
    When you go to... Start / computer... the media slots
    Drive should be listed under... "Removable disk" with a drive
    letter.)

  • Stop the movement of the cursor when you click on the field

    Hey there,

    I am trying to find a way to stop the trackball to move the focus around a bunch of fields I have in a custom handler that I created. I want that the development movement will not apply when the user clicks on a field, with emphasis.

    The reason why I want to do is to move this autour field and NOT the focus.

    Is it possible to implement this switching between the two?

    Thank you for your help.

    NavigationMovement to implement in these areas. Set a Boolean inside this field switch when you click on it, and then, in navigationMovement, check that then call your special treatment and return true or return super.navigationMovement.

  • I received a pdf file and the words in the text of the form filled in and saved tabs/forms appears only in the only filed when you click on this field.

    Hi, the text in tabs/forms of the form filled in and saved text doesn't appear when you click on this tab and field offices. When I go to another tab / filed, it disappears. I need to see everything at once.

    Auto-fill text fields is inactivated.  I have acrobat Pro XI / Win764bit. I can't find anything useful in the German speaking forums (there you will find only: save it on your desktop, open the with another program - not adobe, save it as a .jpg, use the preview and save/print pdf, open with photo shop and so forth but nothing works.)

    It would be good to get a link to an old solution or a useful answer.

    Kind regards

    Is there a chance that the application overview on Mac has been used to complete and save the form? What you describe is a typical sign that it was like overview corrupts PDF forms in a number of ways. You can fix this in Acrobat if you have access to a blank form uncorrupted by exporting the form with FDF data and important in the blank form.

  • Blue screen when you insert the DVD - M40X

    Hello
    I have a new computer laptop toshiba satellite M40x-183. (with DVD super multi)
    After ten days of buying it, I found a problem when playing some DVD and CD, when I insert the dvd I got a blue screen saying... There is an error and windows can stop harmful to your pc and I have to contact the support then start dumping from 100% to 0%...
    I have tried the dvd in many other dvd players and it works perfectly. Team support here told me that this type of dvd player are unable to process this format how it happens so that older toshiba and other laptop brands can do!
    Is there a solution to this?

    Hello

    Well, as the support service team say that the DVD player is not able to read this format.
    But I can't give you a good answer why it s not possible to play this DVD. It s a simple fact that there are many DVD and CD formats on the market and number of readers is not able to play some formats.
    Have you tried to play burn DVDs? I recommend you to test the DVD from other manufacturers. I use TDKs and it works correctly.

    Good bye

    1 Windows operating system you are using?

    If you use Windows 7, then it is not compatible with Windows 7.

    See the link below for compatibility.

    http://www.Microsoft.com/Windows/compatibility/Windows-7/en-us/search.aspx?type=software&s=fable-%20The%20Lost%20Chapters

    Step 1:

    You can try to run the game in XP compatibility mode and see if you can run the game without problems.

    For more information about executing a program in compatibility mode, see the following link.

    http://Windows.Microsoft.com/en-us/Windows7/make-older-programs-run-in-this-version-of-Windows

    Step 2:

    You can also try to install Windows XP mode and then install the game in XP mode and check if you can play the game or not.

    You can view the following link to use Windows XP mode:

    Install and use Windows XP Mode in Windows 7

  • How can I get rid of the error code 0 x 80010108 when you insert the SD card

    My SD card is good and I can access images using my computer to start up. I can also see my saved photo gallary pictures. What I can't do, is when I insert the SD card and select images I get the above error message. Help.

    I would say that you have two choices,

    Photo Gallery of windows open before inserting the sd card,

    Then click on import, then insert the sd card.

    Or you can click on the Start button and click computer.

    Insert the sd card,

    He appears as a removable disk that you can right click and click Open,

    Then manually, copy and paste the files in a folder or an existing one,

    Do not use auto play close the dialog box or use the Windows Explorer instead.

    Oops, that's three choice :)
