With respect to the Variables and safety

Hi Experts,

I'm confusion when implementing security can any one answer for these:

1 > what is the difference between column-level and security level of data security or both are the same.
2 > when you want to implement the time to level of data security we use session variables (for writing query and fill particular user to display only a particular area) or directly we must give permission for group and users in the tables of presentation layer and layer the presentation of properties of table column (column-level security).
3 > session system variables are used only to authenticate use should not use other good things. In what situations we must use session independent of system variables.
4 > if we apply security at the level of the object directly, we can do in the web presentation and the right level layer no need to use variables.

Hi reda,.

When we have implementation of security at the level of the data without the need to create variables directly in the groups assign us permissions and adding the filters for this particular group visible only particular brand and should not visible to everyone.

A. Yes, your writing, but I understand your confusion see my comment

So ultimately, no need to create variables for the right level of data security. Please let me correct if I did something wrong.

A. when it will use variable for the means of security to the level of data if your use of the authentication of external table via the database table, then you need to use ok session variables...

See the link for your details below.

  • with respect to the footer and header area

    Hello

    IAM new to this oracle application express and in the learning process. I want to know about the attributes of the header and footer of the region and for these attributes may be used and I found some java script can be placed in the area and footers if body and html header are present in the page. Anyone can throw some light on this.

    REDA

    Hi reda,.

    There are many things you can do with the parameters of region header and footer area. These would all be the content of the page you want to be added immediately before or after your report (or how whether the region contains). Any valid HTML tag should be ok, it can be placed between the BODY tags on a typical HTML page. Many users will add images, links, introductory text or footer information in them. You can also add javascript if you wish. Some will insist that you use the parameter header HTML on the page definition to do this, however, if you click on the words "Région Footer", you will see that there are several replacements of special channel available on in the foot of the region (e.g. #TOTAL_ROWS # will tell you how many records there are in the report). They can be used for a direct output on the page or you can use the in javascript. In addition, unless you use something like JQuery, you can use the foot of the region in the region in the final on the page to run scripts of type onload.

    The header HTML parameter can be used to post a link specific javascript and/or css files to your page (rather than add them to the page template - which would make available to all the pages that use this template).

    The HTML body parameter is only used to add attributes to the BODY tag, when the page is rendered. It can be any valid attribute - for example, you can add a style attribute that sets a background image for the page. The only thing to note here is that you cannot add an onload event handler if you also set the adjustment of focus of the cursor on "First item on the page" because it uses the event onload as well.

  • What is the difference between the variable and set

    WHAT IS THE DIFFERENCE BETWEEN

    These different versions when it is done using the keyword "variable" and "set."
    and these two are performed outside 'DECLARE '.


    VARIABLE g_monthly_sal NUMBER
    SET p_annual_sal = 5000

    -I understand that p_annual_sal will be considered to be a TANK.
    -ALSO if DEFINE the variable serves as a macro variable, THEN it is necessary to give it a certain value whenever we define.
    If this is not the case, what value would it replace?

    OR does that mean when we want to specify the data type for a variable binding, we should use VARIABLE and
    When we do not want to specify type we use SET?

    Thank you

    Both are SQL * most orders. In a real programming environment you will use these constructions (except in a few rare cases of scripts).

    The difference is the way in which the building will be used later. DEFINE looks more like a string copy & paste. Wherever this substitution variable name is found, it will be pasted into the sql * plus the term.
    VARIABLE creates a real variable. You can change the value and if follwos the usual principles of variables (including the link).

    Example can be found in the docs:

    documentation
    Where and how to use the Substitution Variables

    You can use anywhere substitution variables in the SQL and SQL * more orders, except that the first word entered. When SQL * Plus meets a variable substitution not defined in a SQL command * more will prompt you for the value.

    You can enter any string, at the prompt, even a container of spaces and punctuation. If the SQL command that contains the reference must have quotes around the variable and you include here, the user must include the quotation marks when you are prompted.

    SQL * Plus reads your answer from the keyboard, even if you have redirected the terminals input or output to a file. If a terminal is not available (if, for example, you run the script in batch mode), SQL * Plus uses the redirection file.

    After you have entered a value in the prompt, SQL * Plus lists the line containing the variable substitution twice: once before replacing it with the value that you enter and once after substitution. You can delete this list by setting the variable to VERIFY OFF command.

    The use of Bind Variables
    Bind variables are variables that you create in SQL * Plus and then the reference in PL/SQL or SQL. If you create a variable binding in SQL * Plus, you can use the variable as you would for a variable declared in your PL/SQL subprogram and access the variable from SQL * more. You can use bind variables for things such as the storage of return codes or debug your PL/SQL subprograms.

    Because bind variables are recognized by SQL * Plus, you can display their values in SQL * more or reference them in PL/SQL subprograms that you run in SQL * more.

    Creating Bind Variables
    You create variable bind in SQL * Plus with the command VARIABLE. For example

    Ret_val VARIABLE NUMBER
    This command creates a variable binding named ret_val with a NUMBER data type. See the command VARIABLE for more information. (To list all the bind variable created in a session VARIABLE type without arguments).

    Referencing Bind Variables
    You reference bind variables in PL/SQL by typing a colon (:)) immediately followed by the name of the variable. For example

    : ret_val: = 1;
    To change this variable binding in SQL * Plus, you must enter a PL/SQL block. For example:

    BEGIN
    : ret_val: = 4;
    END;

  • Weird problem with control of the ring and foot

    So I have some sort of weird issue with a control of the ring and a chart. I'm with LabWindows/CVI on a Windows 7 computer. The part of the program I'm looking at is basically to navigate through data - there are several "transition" (rehearsals experience), and you can choose the one that you want to watch in the list.

    Normally, you would select transitional in the list, it plots the data, then it is done, basically. However, all of a sudden (don't know how long it spent for), when I select anything except 'Average', he made all the tracing and such, then it changes control of the ring to 'Average' (it is not plot the average data or generate all the reminders that I can tell).

    Now the thing the more bizarre as you can see below, it seems that the switch happens just when I draw something on the chart:

     

    So, it's just weird. The code in this section is here:

       if(uidc.polyon) {
                polynomial_subtraction(curr_data, np, uidc.polyord, 0); // 0 Skip for now
            }
    
            // Scale the curr_data for gains, then pre-scale the FFT data
            // to have no change in the power spectrum (multiply by (2/np)
            for(j = 0; j < np; j++) {
                fft_data[j] = curr_data[j]*2/np;
                curr_data[j] = curr_data[j]*uidc.fgain[i] + uidc.foff[i];
            }
    
            uidc.fplotids[i] = PlotY(dc.fid, dc.fgraph, curr_data, np, VAL_DOUBLE, VAL_THIN_LINE, VAL_NO_POINT, VAL_SOLID, 1, uidc.fchans[i]?uidc.fcol[i]:VAL_TRANSPARENT);
    
            // Prepare the data.
            FFTEx(fft_data, np, npfft, NULL, FALSE, curr_fft);  // Do the fourier transform
    

    DC is a structure that I use to better organize some UI controls and uidc is for display RAM variables, then dc.fid is the Panel that is embedded in the tab "FID", dc.fgraph = FID_Graph and corresponds to the chart control. Control of the ring is actually in a child Panel, dc.cloc [0]. FID_Graph has a point, it can produce, but the reminder is empty (no not coded something there yet).

    I have also considered that perhaps something in another thread (I don't think there is, but whatever) I see is the cause, however, this behavior still happens on that line. I tried to break in different locations, on hold, then continues, as well by adding a loop containing Delay (0.01), a loop of 100 times. Always happens after the conspiracy.

    Does anyone have any idea why this might be happening?

    Hi Paul,.

    I don't have a solution, but I wanted to point out that, even if you see the ring to change its value only when you call the function of tracing, that doesn't say what this function call that really changes the value of the ring. In CVI, some drawing operations are batched, for performance reasons, and the Panel updates only visually at certain times. One of those moments when you draw a chart data. Yes, the ring changes visually at this time there, but it is probably just 'catch up' a change earlier.

    As you are looking through the code, when the value of the ring, you can use the term > command update UI to force the update panel, so that you don't have to wait for the tracing function and see if all goes well this change happening earlier.

  • Save the State of the Variables and radio buttons

    I designed a form that uses a Raddio Button with three choices. These selectibles toggle choice areas of the form. The user will save the form under a different name for archiving. Now if I save the form, the State of the option button and the variables used in the JS code is not stored. So if I open the file, the form does not reflect the State of the option button and variable.

    What is the best way to implement this?

    Can I save variables and the State of the option button (choice selected) when the user saves the form, and then restore the rear opening?

    Thank you.

    Without knowing more about what you do, it is difficult to give specific information. I'm not sure what you mean about the State of the option buttons, since when a form is saved, their State will not change when it is reopened. To back up data, you could certainly use a hidden field and read using a script that runs when the form is opened.

  • Info for the NETWORK card with respect to the host as a Xml

    Based on some other samples here, I got this, but end up with an empty name for $_. Device (requires PowerShell CTP3 v2.0):

    $report = @()
    $servers = Get-VMHost
    foreach($esx in $servers){
         $nics=$esx.config.network.pnic
         foreach($nic in $nics) {
              $row = "" | Select ESXName, NICName
                   $row.ESXName = $esx.Name
                   $row.NICName = $_.Device # $nic.Device
                   $report += $row
         }
    }
    $report | ConvertTo-XML
    

    An excerpt from the release:

    <Object Type="System.Management.Automation.PSCustomObject">
         <Property Name="ESXName" Type="System.String">devbadesx4.dev2003.wp.fsi</Property>
         <Property Name="NICName" Type=""></Property>
    </Object>
    

    I expect NICName for the $nic. Device in value.  But it produces no output, whatever it is, $_. $nic device. Device.

    One of the problems comes from the fact that you mix two types of objects.

    The Get-VmHost cmdlet returns a HostSystemImpl object.

    When you convert an object API through the cmdlet Get-view that you'll get a HostSystem object.

    The 2nd problem is that the variable $_ represents the current object coming from the pipeline.

    Given that you didn't have a pipeline nothing in the variable $_.

    And given that PowerShell complaint variables your script finished without error.

    The following script tries to solve these 2 problems.

    $report = @()
    $servers = Get-VMHost | Get-View | %{
         foreach($nic in $_.config.network.pnic) {
              $row = "" | Select ESXName, NICName
              $row.ESXName = $_.Name
              $row.NICName = $nic.Device # $nic.Device
              $report += $row
         }
    }
    $report | ConvertTo-XML -As string | Set-Content "C:\nics.xml"
