Hi Expert, please tell me that how can I recover a recording of a cursor based on a condition

There is a slider. Where can be one or more folder shows.

I need to choose Next.

1. If it is displays multiple records that choose this record where a field is showing not null

2. If only one record in slider that choose this one (donot penalty on this field shows null or not null)

Please tell me what I have to do it in.

Thank you

You do it in your query SELECT itself. CURSOR is nothing more than a set of instructions to execute the SQL statement. So, unless you get all records you do not know how many records in the cursor.

Your selection would be something like that.

Select

BeO

Select

count (*) over() num_rows

Of

where

)

where num_rows = 1

(or)

Num_Rows > 1 and is not null

  • How can I disable him flipping back between the pages with PgUp and PgDn? Please tell me that I can!

    From Firefox 4, it seems to have been decided that PgUp and PgDn are now buttons with which you return back between the pages. For me, this means essentially almost lose valuable information, because I actually use up and down pages, so I wonder. How can I disable this new and quite bothersome?

    Please tell me that I can!

    In the details of your system, I see this card installed: Macromedia Shockwave for Director Netscape plug-in, version 8.0

    You also seem to have the last, although always obsolete installed namely Adobe Shockwave for Director Netscape plug-in, version 11.5

    First, click on the orange button Firefox, go to add-ons and Plugins and disable the version of Macromedia.

    Then go to http://get.adobe.com/shockwave/ and update it.

    If the problem persists then, try running Firefox in Firefox to solve the issues in Safe Mode. If it works properly in this configuration, then one of your modules is the culprit.

  • Is - this Windows 8 a transparency identical to windows 7? Please tell him that I can buy it...

    We now see in windows 7, it's the transparency of the taskbar and the high tof of the window. I want to know if windows 8 has this kind of transparency...

    Hello JPReddy,

    It has a transparent notification bar, but that's all. Where you used to see a transparent desktop view when you restore an application that has now disappeared. All borders are now solid rather than transparent. Even the upper part of the window is now solid.

  • How can I delete pages in a 3D table, based on the conditions in two columns

  • How can I recover datalog records written beyond the 2 GB limit?


    I found a solution.

    Here are the steps I took to divide a datalog large (> 2 GB) file into two files more small datalog (each< 2="" gb)="" so="" that="" all="" records="" could="" once="" again="" be="" accessed="" by="" an="" application="" that="" employs="" datalog="" file="">

    1. Open the file datalog as a byte stream file using file open/create/replace.

    2. Search the file for a sequence of bytes corresponding to the ID of the record to the first record to retrieve using binary file reading. (I knew my type of cluster datalog this ID U32 Record marked the beginning of a record.  For efficiency reasons, I have read 100 000 bytes blocks every time and kept track of the byte offset location in the file.)

    3. Search the file for a sequence of bytes corresponding to the ID of the next record (or eof if it was the last record) to determine the size of the current record.

    4. Read the current record in a byte array using read binary file in conjunction with the Position of defined file that works correctly for files up to 4 GB in size.

    5. Repeated steps 2 through 4 for the other subset of records targeted for one of the new files datalog.

    6. For each byte array, flattened the array of bytes to a string (precede the size of the array = False) and then not flattened the binary string (data includes the size of the table = False) according to my record datalog type.

    7. Save each record not flattened (cluster) to the new file datalog.

    Using the above procedure, I was able to bypass the need to create my own datalog file headers so I did not need to understand the specifications of datalog file format.

  • Please tell me exactly how to remove the AVG search function

    Please tell me exactly how to remove the AVG search function

    edited by a moderator for clarity

    You need not repeat dozens of times or use profanity to get help.

    (1) disable all non-essential or unrecognized extensions on this tab. Don't know what it does? When in doubt, turn off:

    Firefox orange (or the Tools menu) button > addons > Extensions category

    Use the links above a disabled extension to restart Firefox if some seem to.

    (2) restore your Google search engine:

    https://addons.Mozilla.org/en-us/Firefox/addon/SearchReset/

    (3) check a user.js file (before the release of Firefox, otherwise the parameters in this file can cancel your cleaning) as described in this article: How to fix preferences that will not save.

    (4) If AVG search took over your page to the new tab (Ctrl + t), which changes as follows:

    (A) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

    (B) in the filter box, type or paste newtab and make a pause so that the list is filtered

    (C) double-click the preference browser.newtab.url and enter the desired value for your favorite page:

    thumbnails (i) (default) Page = > subject: newtab

    (ii) blank tab = > subject: empty

    Firefox homepage integrated (iii) = > topic: welcome

    (iv) any other page = > full URL of the page

    IMPORTANT: If you have AVG software in your Windows Control Panel, you need to remove it.

  • Lost-Hi could someone please tell me where I can find my 25 digit product key

    Hi could someone please tell me where I can find my key thanx, 25-digit product.

    Hello Samuelballantyne,

    If your copy of Windows came pre-installed on your PC then you should be able to locate the product key 25 letter on the bottom of your laptop or on the back or the side if it's a desktop computer.

    If, however, you bought a copy the retail Windows; in other words you bought the OS yourself in a box from a retailer will the product key on the box or the sleeve of the DVD opertaing system.

    I hope that the product key will be in one of these two places. However, another option, assuming you still have the operating system installed on your PC, is to download a third application of the called party Magic Jelly Bean Keyfinder http://www.magicaljellybean.com/keyfinder/ download this application and then run it on your PC it will then show you the product key number.

    In addition, when you write the number make you that read correctly as a B can easily be confused with a 8. If you writeie down the wrong number, then you will not be able to install the operating system properly.

    Adobe Muse. BusinessCatalyst.

    I want to use my previous X site name that I used to have, but he tells me that he can no longer be found?

    For example, X

    So, when I go on X.businesscatalyst.com : he tells me no. START PAGE.

    When I try X.businesscatalyst.com/admin so maybe I can remove my site, but here also it tells me: ERROR: the web site you want to administer is not found.

    When I go back on Adobe Muse to publish; those who publish options show me my old site x. name (so maybe I can just publish the changes)

    When I try to publish my new site on my previous X site name, I can't. He told me to try X 01 or 02 X.

    Please can someone tell me how I can solve this problem.

  • My laptop and erased, and indicated that I should go to a site Microsoft S E who seemed so fishy to me, how can I recover all my files and desktop icons?

    My laptop that has the MSE, went empty and indicated that I should go to a Microsoft S E site which seemed so weird to me because he prayed for me to pay but had no insignia info or confirmation of Microsoft authentication. I had to use two different software to clean my pc.

    When I was doing the scans, I saw all my files and documents being examined, but I still can't access it once all the malicious goods have been deleted by Super Anti Spyware and Malware bytes.

    How can I recover all my files and documents. Help, please!

    Rich.

    Hi Amgood4u,

    1. what happens when you try to access documents and files?

    2. you receive an error message?

    3. did you of recent changes on the computer?

    Method 1

    I suggest that you scan and remove any malware or computer virus infections and check if it helps.

    http://www.Microsoft.com/security/scanner/en-us/default.aspx 

    You can also use Microsoft Security databases to scan your computer

    http://www.Microsoft.com/security/PC-security/MSE.aspx

    Method 2

    If the previous step fails, then check if the problem persists in the safe mode and after back with the results.

    I use windows xp svc pack 3. some how it gets corrupted now and all my important data is in the folder my documents on my desk. I got my account with a password. I tried to repair my widows through the recovery console, but I was unable to open a session in my Windows through this procedure just stuck computer is there. even when I tried to fix it through the installation of windows, Setup also stuck on the step where it says "in search for earlier versions of windows."
    now, I tried to copy the data by accessing another operating system on another hard drive but when I opened my account administrator located in the documents and settings folder, it says access is denied. I really need that data on these files is very important to me.
    If you have an administrator password in windows, then the recovery console would need in order to log in the disk system, i.e. the c prompt.
     
    If you tried to do a repair with the cd, then it may not have worked if your cd is the sp2 version of windows on your computer has been updated to sp3 version.  for the sp2 of xp cd works, you will need to uninstall the update to sp3 via Add/Remove programs.
     
    so, now that you have enslaved the hard drive on another computer, you will need to do is try to take ownership of the files/folders:

    Hello

    I'm happy to help you

    Glancing at the screen shot you posted, your looks of partition fine recovery (recovery (D).

    Save your files on an external hard drive or flash drive (depending on how many you have).

    Once that is done, disconnect all connected to your PC, but the AC adapter.

    Start the PC and the HP welcome screen, press the F11 key to start the Recovery dialog box and follow the prompts.

    It should take 15 to 30 minutes and your PC needs to be restored to its factory settings.

    Then just reinstall all programs and files that does not come with the PC.

    You will need the files or the installation of program diskettes. You cannot back up installed programs and reinstall them using a backup.
