Pass the variable null

Hello

I have a script to create a new hard drive for the virtual machine

How to change my script to skip the creation of hard drive if the cell of hardisk1 does not have a value (empty)!

$harddisk1 = $Data.harddisk1
$DatastoreName1 = $Data.DatastoreName1

$Name | New-harddisk - CapacityGB $harddisk1 - data store $DatastoreName1-persistence persistent

Hello, VicMware-

You can simply wrap a conditional statement around that to verify that the values for harddisk1 and DatstoreName1 are non-empty string values non-zero.  As:

## if neither item is null or an empty string, then add the new hard diskif ($Data.harddisk1 -and $Data.DatastoreName1) {    "Ok, will do something for $Name"    $harddisk1 = $Data.harddisk1    $DatastoreName1 = $Data.DatastoreName1    $Name | New-HardDisk -CapacityGB $harddisk1 -Datastore $DatastoreName1 -Persistence persistent} ## end if## else, do something elseelse {"hm, maybe missing some data for VM $Name"}

Or, if you want to be a little more explicit with the line that checks the value null or empty, you can replace the line 'if' above with:

if (![string]::IsNullOrEmpty($Data.harddisk1) -and ![string]::IsNullOrEmpty($Data.DatastoreName1)) {...

Those who should be working [almost] identical.  How do for you?

  • @HspNumToString () cannot pass the variable as a parameter?

    Hi all

    I create a rule that uses @HspNumToString () and pass a variable as a parameter.

    But it gives error on validation below the code associated with the @HspNumToString function.

    Var itemCounter = 1;

    ...

    DIFFICULTY ({UserEntity}, {period}: Dec,@MEMBER (@CONCATENATE ("Item", @HspNumToString (itemCounter))))

    ...

    ENDFIX

    and the error message is:

    "Error: formula [statement of DIFFICULTY] (line 97) parse error: invalid object type rule.

    IF I move a number as a parameter to @HspNumToString (), for example @HspNumToString (2) then the rule will be valid.

    Hello

    I'm afraid that's how it is. You cannot use variables of calculation in trouble.

    Instead, you can set a static member of this dimension (i.e. "no element") and by your use of calculation an operator cross dimensional to calculate the item desired.

  • How to pass the variable to bind page ADF view object

    Would appreciate your help on this.
    Set up a view with a variable binding object: param1 in where clause.
    I want to pass the value of the variable to link from a page of the ADF (.jspx)

    I know that one Option using executeWithParams() method binding in the ADF page.
    But, I want to pass a pageFlowScope parameter (which is already set when loading the page) to the variable binding VO, and the VO should also display the results filtered on the page the first time itself.

    Could someone help me understand with a code, how to achieve the same. (Is there a groovy expression to access the param pageflowscope?)

    Thank you

    Published by: user5381160 on August 12, 2010 20:01

    You should also consider dragging operation executeWithParams on your workflow and of wiring to occur before your page instead of in the definition on the page itself - so it is more clear what is happening and is the approach recommended for 11 g applications. When drag-and you - drop operation, you can use the dialog box bind the parameter to your page flow - scope variable by providing the good EL there.

    There is no expression Groovy in the model layer to access the workflow variable scope page (which is in the controller layer) because this would violate the separation of concerns inherent in an MVC application.

  • by comparing the value to the variable null

    Hey guys, quick question. I just want to see if my understanding of the code below is correct:

    Declare
    v_variable varchar2 (100)
    Begin
    v_variable: = null;

    If v_variable = 'test' then
    message ('test');
    end if;

    If v_variable! = 'test' then
    message ('test2');
    end if;

    If my interpretation is correct, "test2" message should print but wont 'test' or is it possible that I could get an error if we cannot compare with null values?

    Thank you

    Thank you.




    End;

    You must compare the values null, is null. A comparison of null = or! always = the NULL value and thus you reach your outings:

    $[CHE_TEST@asterix1_impl] r
      1  begin
      2  if null = null then
      3  dbms_output.put_line('result: true');
      4  elsif null != null then
      5  dbms_output.put_line('result: false');
      6  else
      7  dbms_output.put_line('result: else');
      8  end if;
      9* end;
    result: else
    

    The two if the conditions are evaluated to NULL, then the else branch is executed.

    acutally null = null evaluates to null as you can see:

    $[CHE_TEST@asterix1_impl] r
      1  declare
      2    bres boolean;
      3  begin
      4    bres := null = null;
      5    if bRes is null then
      6      dbms_output.put_line('Result: NULL');
      7    else
      8      dbms_output.put_line('Result: NOT NULL');
      9    end if;
     10* end;
    Result: NULL

  • How to pass the variable to a swf into another swf

    I declared a variable in the one.fla file

    I open another file swf on a button.

    the code is as follows

    name = 'personName ';

    myButton.onRelease = function () {}

    trace ("liberation" + name);     personName

    loadMovie ("mainPage.swf", _root);

    _root.loadMovie ("mainPage.swf");

    }

    I want the variable 'name' of access to another swf file. IE (mainPage.swf)

    How do I do that?

    You want to use the MoveClipLoader class (using loadClip() and addListener methods) rather than loadMovie so that you can wait for the file to load before you try to access anything in it.  You can create an empty movieclip to load the SWF in, and in this way the loaded file can be targeted using the empty movieclip instance name.

    What you see are special values representing NULL using the adapter of Apps. Are also inside the Apps there are special constant values such as G_MISS_NUM, which is equal to ' 9900000... "and G_MISS_CHAR, which is equal to" chr (0) ' he constants to date as well. So, when you are in mode Apps (using Oracle applications adapter) and you pass null values (for example, xsi: Nil = 'true'), you will get these special values. It's behavior that has been specifically requested by the Apps Team.
