You attempt to add a column with a SUM function

Hello

I am new to Oracle (using 11 g) and I try to add a new column in my table with one facility amount.

Currently, I have a weekly Chronicle of salary, but I would like to add an annual salary that uses the data of the week.

Example I tried was:

change the emp table add)

yearly_wage SUM(WEEK_WAGE*52));

Is it possible to do this please?

Thank you

  • you attempt to add a web form of Business Catalyst to my site Web of Adobe Muse (via insert html) and the shape is cut all the content below where to place the html area.

    You attempt to add a web form of Business Catalyst to my site Web of Adobe Muse (via insert html) and the shape is cut all the content below where to place the html area. I tried the basic troubleshooting and it's only when I insert a form of Catalyst Business that my web page is cut, where is the bottom of the form. I use this code when you insert form BC in Muse,

    "< div class ="bulletin of information-form"> < form name ="catemaillistform58787"onsubmit ="return checkWholeForm58787 (this)"method ="post"action =" http://theincitejournal.BusinessCatalyst.com/CampaignProcess.aspx?ListId=53681& OPTIN = true & PageID = / index.html"> < div class ="form"> < div class ="item"> < label for ="CLFullName"> full name < / label > < br / > < input class ="cat_textbox_small"type ="text"name ="Full name"id ="CLFullName"maxlength ="255"/ > < / div > < div class ="item"> < label for ="CLEmailAddress"> E-mail address < / label > < br / > < input class ="cat_textbox_small"type ="text"name ="EmailAddress"id = '" "CLEmailAddress" MaxLength = "255" / > < / div > < div class = "item" > < label > Enter Word verification in box below < / label > < br / > {module_captchav2} < / div > < div class = "item" > < input class = "cat_button" type = "submit" value = "subscribe" id = "catlistbutton" / > < / div > < / div > < script type = "text/javascript" src = "http://theincitejournal.businesscatalyst.com/CatalystScripts/ValidationFunctions.js" > < / script > < script type = "text/javascript" > '

    The only settings I did took the H3 header on opt-in and page navigation after the action to get rid of the opt in BC function as default. I tried to download the source code as well and I'm having the same problem. The web Page is here " copy " and a version of what I was creating the page to look like here is ' home ' As you can see, the 'House' version allows me to scroll past where I would have placed the shape box while the 'copy' stops at any user to parade before. I have called the shape slightly from the "development" of British Colombia under the style sheets tab and still tried to trouble shoot and get rid of the code to see if it affects something and it did not add style. For some reason only the HTML to the form is but I cannot understand what the section of the code would do that. Any ideas?

    I see that you have inserted a script tag open that you forgot to close, which generates errors on the page and prevent it from be returned correctly. You should ensure that the code that you insert in the Muse is syntactically correct.

  • How can I add a column with my favorites for my screen?

    I just started using Firefox now and can not find a way to add a column on the left side of my window in Firefox (which I didn't in Internet Explorer) showing all the links to my favorite site. In which case it is important, I use Window XP as my operating system).

    To show your Firefox Bookmarks Sidebar ("Favorites" are in IE, not Firefox), use CTRL + B to open or close the sidebar. If the bookmarks bar is open when you exit Firefox (Firefox button > exit or file > exit), it should be open when you restart Firefox.

    • You can also use the following to open or close the bookmarks bar

      • Press ALT or F10 to temporarily show the Menu bar, click View > sidebar > bookmarks to check/uncheck it (checked = displayed; United Nations-checked = not displayed
      • Hold down the ALT key while pressing the VEB keyboard letters

  • Call "HostNetworkSystem.UpdateVirtualSwitch" for the error of the object when you attempt to add the second NETWORK card

    Hi there - first post here, so please be nice :-).

    We are just trying to place an ESX4.1 own deployment in our environment (no previous installation of VMWare) to our main office, using Dell M610 and blades blades M600 to what would become our DR - two sites site hosting VMS on Equallogic iSCSI SAN disks.

    I configured 4 of our blade M610 with ESX 4.1 successfully and they work very well.  These blades have double NIC onboard, and after the initial installation of ESX, I could go to the virtual switch and add in the second NIC like vmnic1 (because one had already been detected during installation).  This fine workd for 4 guests on the M610 blades.  However, I came today to make my first installation on one of the old M600 blades and I encountered a problem.

    Installation went without any problems and I was able to add the host in my vCenter.  I can change all the settings without problem (created the Port of VMKernal for my connection to SAN iSCSI etc, but as soon as I try to add in the second NETWORK card, he paused for a while, and then I get the following error message:)

    Call 'HostNetworkSystem.UpdateVirtualSwitch' of object 'networkSystem-56 "on vCenter Server"VCEN01." ournetwork.local"failed. (network name has been changed for post).  When this happens, it locks up again for several seconds, and when the system returns, I can no longer communicate with the ESX host (Observer of events in vCenter watch 'host is not responding' and I find that I can not ping the host unless I reboot it.)

    If anyone has any suggestions I would appreciate it that I don't want to proceed down to the line with our Installer if theres an underlying issue and I need to redo everything.

    Concerning

    EFIN.

    Do you get the same error when you try to add the network adapter by using the command line?

  • You attempt to add a word at the end of a link tag to the site level

    I try to add a word before closing qoute in all links to the site level. Any way to do it without each link on all pages separately?

    I tested on a single page, so I'm confident, that it will do what you want, but before you continue, you must make a backup of your site in case something goes wrong.

    1. Open the find and Replace dialog box (Edit menu or Ctrl + F / Cmd + F).
    2. The value "search in", "current Document".
    3. The value of "seeking to"Source Code".
    4. In the 'Search' field, add the following regular expression:
      (
    5. In the field "Replace" add the following line (replace "NewText" with the text you want to add to each link):
      $1new_text$2
      
    6. Select the checkbox "use regular expression.
    7. Test that it works by clicking on find followed next to replace.
    8. If you are happy that it works as expected, change ' search in ' to "Entire current Local Site" and click "replace all".

    Dreamweaver warns you that you cannot undo the changes in pages that are not currently open. If you are satisfied, click OK, and the change will be at all the links.

  • Message to "Capture device offline" when you attempt to add additional clips from HDV camcorder, in CS5

    "Device capture offline" message when you try to add additional clips to an existing project in first Pro CS5.5.2.

    Previous capture has been accomplished, but, then, in trying to add additional clips of the same device, it failed.

    Every 40 minutes of excerpts of 185 was initially captured by using Sony Vegas Platinum 11 Moviemaker, without error. Additional clips of mt2 were then imported successfully into Premiere Pro after indexation, which conform clips, and they play perfectly well and high quality CS5.5.2 at 1440 x 1080i.

    Why the Capture device would be offline, where no physical alteration has been made to the equipment?

  • Add a column with customization. How do to this capture in a table.

    Hello

    I added a column in a standard page with personalization. Please tell me how to capture this value and store it in a custom table. I went through various websites, but please tell me in a simple way to add this code.

    i. do I need to extend the controller?
    II. do I need to create a package? (can I do without creating a package.)
    III. I will add the code directly in the standard CO.java


    Kind regards

    Prakash

    What you can do, is extend the controller. Get the value entered by the user in your domain, and then pass this value to data bases and save it in the database using the procedure. As a reference, you can go through the code below.

    import oracle.jdbc.OracleCallableStatement;
    
     OAMessageTextInputBean mstb = (OAMessageTextInputBean) plb.findChildRecursive("Attribute1");
    in_parm1=mstb.getValue(pageContext);
    
    String stmt = "BEGIN test(in_parm1 => :1); END;";
    OADBTransaction txn = getOADBTransaction();
    OracleCallableStatement cs = (OracleCallableStatement)txn.createCallableStatement(stmt,1);
    try
    {
    cs.setInt(1, in_parm1);
    //cs.registerOutParameter();

  • you attempt to add as an attachment to an e-mail message block Thunderbird, why

  • You attempt to add a 2nd hard drive

    I have a HP Pavilion Elite HPE 510 t. I try to add a 2nd hard drive. The 2nd hard drive is a Toshiba 1 TB 7200 RPM 6G.

    Accordingly, the 1st HDD was plugged on SATA2 and the CD-ROM was connected to SATA1. It worked and it started ok.

    I added the 2nd hard drive, plugged on SATA3, went into the BIOS Setup and it has not even see SATA3.

    I then plugged the CD-ROM on SATA3 and the 2nd hard disk on SATA1 and lit, is went into the BIOS config amd saw 2 hard drive and a hard disk 1, it did not see the Wired CD SATA3. Then I tried SATA4-nothing.

    I have advanced and partitioned and formatted the hard drive into two partitions 2 and recovered the data from a backup on each partition.

    It works very well, with both devices, but nothing I have connect SATA3 or SATA4 is recognized by the BIOS.

    Can someone tell me why? is there a jumper on the system board or a setting in the BIOS that turns on SATA3 and SATA4?

    Are my bad SATA3, SATA4?

    I've seen the specifications for hard disks. He is said to use a 1 to 3G 7200 RPM. IS the fact that I use a 1 to 7200 RPM 6 G the cause? Even with the hard drive 2 disconnected and hard drive 1 SATA1 or 2 and SATA3 or 4 CD, it does not yet recognize the CD-ROM drive.

    I tried to pass autour SATA data cables, but it has not changed. Anyone know why the system will not recognized the connected CD-ROM SATA3 or SATA4?

    Or whatever it is well plugged SATA3 or 4? I can run both hard drives, but then I don't have a CD-ROM drive, or I can run a hard drive and a CD-ROM drive, but not 2nd hard drive.

    Any suggestions? I know choose IDE used to have to set a date for the cable, but I don't think that SATA requires that.

    Am I wrong?

    I bought a $70 ServerSupply.com motherboard, succeeded him and it solved the problem.

  • Microsoft Word and Excel (2010) do not appear when you attempt to associate file types with applications.

    Word and Excel are installed and are working on the new computer from my parents.  They have the word 'old' and the files whose file extensions are not associated with Word or Excel is excellent.  If they open Word (or Excel), they can then open these old files successfully.  On the other hand, if they double-click on the file, the popup shows the type of file is not associated with an application.  When asked to choose an application to associate, the list does not include Word or Excel.

    The same is true when you use the programs Start/Default/associate a file type or Protocol with a program.  Word and Excel are not shown as applications installed on this computer.

    I did an uninstall and reinstall, and the old word files and excellent files are still not associated.  I was then able to associate using the types of programs/associate of start/default etc..  So I think I'm good to go.  This occurs naturally, and it was a big pain.  Not what you want to experience, unfortunately, visitors.

  • You attempt to add the audio progress bar

    Hello

    I would like to add a progress bar to my Player audio flash.

    At the moment you press a button, a certain sound load and then plays.

    Here is the part of the code:

    function playSong(e:Event):void {}
    If {(my_channel)
    my_channel. Stop();
    }
    var myURL = ("mysong.mp3");
    my_sound = new Sound();
    my_sound. Load (new URLRequest (myURL));
    my_channel = my_sound.play ();
    }

    In order to build a progress bar, I wanted to know the length or duration of the sound, but I keep getting some error messages or 0s in return

    trace (my_sound.duration);

    tells me that the duration is a property not defined

    trace (my_sound.length);

    trace (my_sound.position);

    trace (my_sound.bytesTotal);

    trace (my_sound.bytesLoaded);

    all give me in return a 0

    No idea why? Why can't I access my sound properties?

    I would also be very grateful for any other suggestions on how to add a progress bar. I tried a number of Web sites, but most of the samples are AS2 code...

    Thank you

    Julie

    After loading is completed, check the length of your sound.

  • Classic report - add the column "select box"?

    I have a classic report and you want to add a column with a check box so that the user can select several lines and perform an action on all of the lines (delete selected, for example).  Looks like it should be easy and maybe integrated features, but I don't find it.  Is there a standard way to do this?

    Steve

    APEX 5.0

    Hello

    to add a box to your classic report using apex_item.checkbox like this API function:

    select
        APEX_ITEM.CHECKBOX(p_idx=>1, p_value=>DEPTNO)  as select_dept,
        DEPTNO as DEPTNO,
        DNAME as DNAME,
        LOC as LOC
    from DEPT
    

    You can access the values checked (for example in a process page)

    declare
    v_deleted_depts number := 0;
    begin
    FOR i in 1..APEX_APPLICATION.G_F01.count
    LOOP
      v_deleted_depts := v_deleted_depts + 1;
      delete from dept where deptno = APEX_APPLICATION.G_F01(i);
    END LOOP;
    :P1_DEPTCOUNT := v_deleted_depts;
    end;
    

    P1_DEPTCOUNT (hidden) is just for later interaction with this procedure - for example, you want to present your users with a message of success and error custom as "Deleted & P1_DEPTCOUNT. departments. »

    Maybe you would like to add an option to check all checkboxes at once. If so, read this blogpost Blog of Carl Backstrom: September 2007.

    Kind regards

    Pavel

    Edit: don't forget to toggle the leak key for special characters not your column "checkbox.
