How to get tab name value?

Hi,
I have a database table which stores user tab privilige info.
It stores tab_name, username, and access_flag.
eg.
tab_name--username--access
T_tab1------- xyz------------Y
T_tab1------- zzz------------Y
T_tab2------- xyz-----------YI am creating a tab condition for T_tab1. If user has priviliges, user will see the tab, else no.
I have a PL/SQL function in the database which accepts tab_name and username and return 'T' or 'F' based on table rows.
I have written following statement in 'T_tab1' tab expression(PL/SQL Function body return a Boolean):
IF get_tab_access('xyz', v('TAB_NAME')) = 'T' THEN
RETURN 'T'
ELSE
RETURN 'F'
END IF;During my testing6 I found that v('TAB_NAME') is not passing value to the function.
Can someone tell me how to pass current tab value to the fuction?
Thanks in advance.

  • How to get the name of the current tab.

    Hi Experts,
    I have two tabs in my tab strip and a button common to both the tabs.Can you please let me know how to get the name of the current tab in the event method of the push button.
    Thanks in advance.
    Regards,
    Arun

    1.Declare an Action for OnSelect event of Tabstrip. This event is triggered whenever any change in tab occurs.
    2. Declare an Import Parameter in this method
       Tab type String.
    3. This parameter has value of the selected TAB.
    4. You can set this value in some Attribute in Attribute Tab in this event only (OnSelect):
         wd_this->Att  = Tab.
    Att is the attribute created by you in Attributes Tab of View. ( of type String)
    5. Now the selected Tab ID is stored in this Attribute Att.
    6. In the Onaction of Button , retrieve the selected tab value from this attribute using :
               Data : lv type string.
                lv =  wd_this->Att
    Now lv has your selected TAB ID.
    I hope it would help you.

  • How to get all the values from the dropdown menu

    How to get all the values from the dropdown menu
    I need to be able to extract all values from the dropdown menu; I know how to get all those values as a string, but I need to be able to access each item; (the value in a dropdown menu will change dynamically)
    How do I get number of item is selection dropdown?
    How do I extract a ?name? for each value, one by one?
    How do I change a selection by referring to particular index of the item in a dropdown menu?
    Here is the Path to dropdown menu that I'm trying to access (form contains number of similar dropdowns)
    RSWApp.om.GetElementByPath "window(index=0).form(id=""aspnetForm"" | action=""advancedsearch.aspx"" | index=0).formelement[SELECT](name=""ctl00$MainContent$hardwareBrand"" | id=""ctl00_MainContent_hardwareBrand"" | index=16)", element
    Message was edited by: testtest

    The findElement method allows various attributes to be used to search. Take the following two examples for the element below:
    <Select Name=ProdType ID=testProd>
    </Select>
    I can find the element based on its name or any other attribute, I just need to specify what I am looking for. To find it by name I would do the following:
    Set x = RSWApp.om.FindElement("ProdType","SELECT","Name")
    If I want to search by id I could do the following:
    Set x = RSWApp.om.FindElement("testProd","SELECT","ID")
    Usually you will use whatever is available. Since the select element has no name or ID on the Empirix home page, I used the onChange attribute. You can use any attribute as long as you specify which one you are using (last argument in these examples)
    You can use the FindElement to grab links, text boxes, etc.
    The next example grabs from a link on a page
    Home
    Set x = RSWApp.om.FindElement("Home","A","innerText")
    I hope this helps clear it up.

  • How to get all the values of a variable with F4 with checkboxes to select

    Dear Experts,
    After Executing a query by giving let 3 values(Out of 10 Values) to a variable.
    To give 2 more input values to the same variable(i.e.,total I wanted to give 5 inputs this time ),after refreshing the query,for that variable if I click F4, I am seeing the historical values(i.e.,3) and remaining 7 values also But with out any Check Boxes besides them to select the 2 inputs.
    In the same F4 Screen, If I click all values(an Icon at The bottom),then also Im seeing but no check Box.
    I hve tried by deleting the Delete Personalization also,but no use.
    Please tell me How to get all the values with F4 with check boxes to select ,whatever I want??
    Thanks in advance

    Take a look at the InfoObject and go to the Business Explorer tab. If the 'Query Def. Filter Value Selection' is set to 'Only Values in InfoProvider', you're only going to get the values in F4 that exist in the InfoProvider, not everything in the Master Data. This would need to be changed to the value of 'Values in Master Data Table' if you want it to show everything possible when F4 is chosen.
    Likewise, you're going to need to look at the query and go to the Advanced tab for the InfoObject. Make sure that the radio button for 'Values in Master Data Table' is selected. If not, then you should change that selection.

  • How to get the attribute values out?

    Hi everyone,
    <root>
    <category name="Mens Clothing" id="0">
    <subcategory>Active/Baselayer Tops</subcategory>
    <subcategory>Active/Baselayer
    Bottoms</subcategory>
    </category>
    <category name="Womens Clothing" id="1">
    <subcategory>aaa</subcategory>
    <subcategory>bbb</subcategory>
    </category>
    </root>
    How to get the attribute values out? For example "Mens
    Clothing" and "Womens Clothing".
    // the line below returns "Active/Baselayer Tops" and
    "Active/Baselayer Bottoms"
    var myXml:XML = new XML(event.result);
    Thanks,
    May

    Here is attribute identifier operator from FB Help:
    @ attribute identifier Operator
    Usage myXML.@attributeName
    Identifies attributes of an XML or XMLList object. For
    example, myXML.@id identifies attributes named id for the myXML XML
    object. You can also use the following syntax to access attributes:
    myXML.attribute("id"), myXML["@id"], and myXML.@["id"]. The syntax
    myXML.@id is recommended. To return an XMLList object of all
    attribute names, use @*. To return an attribute with a name that
    matches an ActionScript reserved word, use the attribute() method
    instead of the @ operator.
    Operands attributeName:* — The name of the attribute.
    Example
    How to use examples
    The first example shows how to use the @ (at sign) operator
    to identify an attribute of an element:
    var myXML:XML =
    <item id = "42">
    <catalogName>Presta tube</catalogName>
    <price>3.99</price>
    </item>;
    trace(myXML.@id); // 42The next example returns all attribute
    names:
    var xml:XML =<example id='123' color='blue'/>
    var xml2:XMLList = xml.@*;
    trace(xml2 is XMLList); // true
    trace(xml2.length()); // 2
    for (var i:int = 0; i < xml2.length(); i++)
    trace(typeof(xml2
    )); // xml
    trace(xml2.nodeKind()); // attribute
    trace(xml2
    .name()); // id and color
    } The next example returns an attribute with a name that
    matches a reserved word in ActionScript. You cannot use the syntax
    xml.@class (since class is a reserved word in ActionScript). You
    need to use the syntax xml.attribute("class"):
    var xml:XML = <example class='123'/>
    trace(xml.attribute("class"));

  • How to get item field values for old versions?

    I need to be able to query old field values from previous versions of items in a SharePoint list. I can't execute code on the server (it needs to work with SharePoint Online/O365 for a start).
    So far the ONLY API I've that lets me do this is the lists.asmx GetVersionCollection SOAP call.
    This lets me specify a single field name and returns an XML structure with the values for the various versions, along with the modification time and who made the change - but NO reliable way of actually identifying *which* version (i.e. an ID or label). That
    is, if I know I need to fetch the Title value from version 512 ("1.0") of item 1 in list "Documents", I don't see how to reliably parse the results to determine which entry is version 512. While they may be returned in order, in many cases
    the entries are actually missing when there was no field value present (or perhaps when the field hadn't been created yet). I've tried comparing the Modified date to the Created date of the corresponding FileVersion item (which I can get via CSOM or REST),
    and while it works some of the time, it's not reliable. I've also looked at the output from the lists.asmx GetVersion API but I don't see how that's useful either, as the Created property for all versions always seems to be just the date the file was originally
    created.
    It does seem odd to me that there's not a neat way of doing this - if I need to return information for several fields but just for a single version, I have to make a whole lot of requests that return far more info than I need, and then I need to figure out
    how to parse the returned text in the case of, say, multiple-value taxonomy fields etc.
    Anyone tried doing anything similar here?
    Thanks

  • How to get least date value

    Edited by: kolipaka on Jun 29, 2012 4:21 PM30-Jan-2010 is the earliest (least) date in that data (assuming that's a DATE column, and all the dates are in the same century). To find the earliest date, you could say:
    SELECT  MIN (dt)    AS first_date
    FROM    table_x
    ;DATE is not a good column name, so I used DT instead.
    03-Mar-2012 is the date related to the least order_id. To find that, you could say
    SELECT  MIN (dt) KEEP (DENSE_RANK FIRST ORDER BY order_id)  AS dt_or_least_order_id
    FROM    table_x;If you wanted to find several columns from the row with the earliest order_id, you could do a Top-N Query , like this:
    WITH  got_r_num  AS
        SELECT  x.*
        ,       ROW_NUMBER () OVER (ORDER BY  order_dt)   AS r_num
        FROM    table_x  x
    SELECT  *    -- or list all columns except r_num
    FROM    got_r_num
    WHERE   r_num   = 1
    I hope this answers your question.
    If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
    Explain, using specific examples, how you get those results from that data.
    Always say what version of Oracle you're using.

  • How to get procedure paramater value dynamicly ?

    How to get procedure paramater value if the parameter name is stored in a text variable?

    thanks for help
    Cecak

    Let me explain it again what I need using different words.
    I need to write an universal code which will be able to identify name and value of parameters of called procedure/function.
    It means I do not want to hardcode the list of all procedure/function parameters into one command DBMS_OUTPUT.PUT_LINE('p_par1 is '||p_par1||', p_par2 is '||p_par2.....) placed as first statement of a monitored procedure/function.
    If a new verison of the same procedure/function having one additional parameter is compiled I would not need to modify the first command of the procedure/function to show name and value of the additional parameter because it would be done dynamicly.
    SQL> create or replace procedure procedure1(p_par1 varchar2, p_par2 varchar2) IS
    2 begin
    3 for v_col in (select * from USER_ARGUMENTS where OBJECT_NAME = $$plsql_unit order by position)
    loop
    4 DBMS_OUTPUT.PUT_LINE('column_name : ' || v_col.ARGUMENT_NAME);
    5 end loop;
    6 end;

    Procedure created.

    3 end;
    4 /
    column_name : P_PAR1
    column_name : P_PAR2
    PL/SQL procedure successfully completed.
    How can I get value of the procedure parameters if the parameter's names are stored in a text variable?
    My DB version is:

  • How To Get Attribute Names for a Particular VO

    Hi ,

    So wen i am creating new Column to existing Table RN and we Need to add Attribute Name Also...Rt..

    Ex: PlanId is the Java VO Attribute Name for the Database Column PLAN_ID
    In The Same way Hw We Get the Relation ship for All other columns In the Controller Cllass ..
    Can Any One Reply as It is urgent Req...
    Thanks ,,
    Jithen

    Instead of using the VO attribute names to set and get values, best to go to the VO definition, click on Java, and generate the View Row Class with the accessors.
    In the class where you're trying to set attributes, instead of a Row class, use the View Row class of your VO (eg ViewObjectName's class would be ViewObjectNameRowImpl), and when retrieving a row from the VO, cast the row to the previously mentioned View Row Class.
    At that point you can use the View Row Class's methods that would perform sets and gets of each column.
    To get attribute names, I don't know off the top of my head, but there might be a method mentioned in the Javadoc for the ViewRowImpl or ViewObject or ViewObjectDefinition classes to get the attribute/column mapping, or perhaps you can somehow read the XML definition of the VO which has that mapping.
    Assuming business components were built automatically and no attribute names were overridden, intuitively the attribute name is a camelcase version of the column name, removing understores and capitalizing the character following the removed underscore - but that's not a fool proof approach. Just a general observation.
    Hope this helps.

    Hi,
    What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.
