Filter Table ADF | with the Like operator

Dear all,

I use JDeveloper 12 c.

I have an obligation to provide the filter on the table with the 'Like' operator

I'm following Ashish Awasti method on it. Ashish Awasthi (Jdev/ADF) Blog: filter on af:table column programmatically, Invoke 'FilterableQueryDescriptor' t...

All very well here. In "FilterableQueryDescriptor" default search operator is "begins by". Is it possible to change the operator "starts by ' to 'Like' operator.

Please suggest.

Thank you

Vieira

An addition: If the op just wants to use the like operator, it must use the data of the field in the table, as is. View implizite criteria build for filter uses

(((Countries.COUNTRY_NAME COMME (: bindName ||))) (('%')) OR (: bindName IS NULL)))

for the startswith operator.  Yes ther EI '%' added automatically. It should be replaced by

(((Countries.COUNTRY_NAME COMME (: bindName)) OR (: bindName IS NULL)))

to be a true sql 'like' operator. Then, the user must enter the filter with the '%' residue criteria to perform a generic search.

Adding a '%' before the setting is counterproductive because it can be a bottleneck. The PB needs to do a full table scan to get the result!

Then it would not behave as the sql like operator that you can search for '? URO % "for"europa". If, for example, a line with "western europe" is your setting ' %? % ships ' grab this line too.

  • Data control for the Web Service based filter table adf only appear not

    I have a SOAP web service I'm consumption as a web service data control.

    When I use one of the results of the web service through data to the web service in the form of a table control in the user interface with the filter and sort, I don't see the filters on the top of the table.

    It comes to JDeveloper version 11.1.1.7.

    Please let me know if anyone has an idea on this issue.

    TIA

    ABS

    You need connect your own logic on the filtering table.

    The table doesn't actually do the filter - it does, is the data control to filter the info - for a Web service we do not know how it will actually make a sort-, so you'll need to add a filterListener on the table and call a WS that will be returned the filtered data method.

  • Refresh of partial with ADF table Page with the form

    Hi all

    I have an ADF table that is bound to a data control Bean. When a user clicks a row in the table of the ADF, I want the content of the line to display in a form on the same page.

    The table is called 'List of queries' and shows:
    ID of the request
    Name
    Submitted Date
    Expiration date

    The form will display information for the selected applications:
    ID of the request
    Name
    E-mail
    Phone
    Submitted Date
    Expiration date
    Reason for the request

    Please can anyone help point me in the right direction? I need to link my form to the table? Do I need a data control for individual applications? Is there a good tutorials out there for this?

    Thank you!

    User, please always tell us your jdev version.

    It's easy to do. Drag the vo that represents your table on the page and drop it read only table on the page. Make a unique selection of the table. Drag the vo of the data control on the page again, this time a fall as form ADF table below.
    That's all.
    Now, if you select a row in the table selection will change the form data.

  • Create table ADF on the backing Bean page

    Hello
    I am currently able to recover and iterate/modify the data of a base of the Interior of the module of the Application manually (storing the changed data in a table). How ever I don't know how to put these data from the Module to the Application page that called? I'm assuming that I need the method that is called to return an CoreTable that would be then displayed on the page. It is the right approach and how would I go to do this?

    Thank you



    Steve

    Hi Steve,.

    There are several ways to do this:

    -With the help of your:
    a. entity create and display objects to database tables and then add objects to view the module of the application
    b. drop the View object in the data as ADF Table control palette in the jspx page
    c. you can also drop some operations like CreateInsert(for insertion), remove, Commit, Rollback etc.
    d. If you want to perform operations on existing data, you can write a single method in AMImpl or VOImpl and modify the view object by the criteria of view running or where clause, then call this method from jspx page by exposing to the client interface

    -Programmatically binding value to table:
    a. create a method in AMImpl and return the records in the list and exposing it to the client interface
    b. Add the binding of the method in page jspx
    c. write a method in bean which return ListDataModel and link it to the value property of the table
    d. inside the bean method, call your AM method in getting the operationBinding
    e. give the list returned by the AM method to the listDataModel.setWrappedData method

    -You can prepare the entire table in the bean and then can link it to the table using the bindings property
    Among all the three ways, according to me, the first one is effective and simplest, you can choose one based on your requirement

    ===========================================================================================================================

    Could please help what is wrong in the code, I followed all the steps as stated in the guide, but the table advance, the problem starts whenever I click on the button Add a new row for the creation of new line.

    I couldn't understand what was wrong with the code.

    Thanks in advance,

    Suman

    Suman,

    A few points:

    1. Why do you call handleCurrencyChangeEvent in the event to add a line? Simply set the useful, likely of the values in the line it himself.

    ex:-instead of calling the handleCurrenyChange method, simply add the below lines inside the createDetailRow()

    dtlrow.setAttribute ("ExchangeRateTypeRender", Boolean.FALSE);

    dtlrow.setAttribute ("ExchangeRateDateRender", Boolean.FALSE);

    dtlrow.setAttribute ("ExchangeRateRender", Boolean.FALSE);

    2. it looks like you have on the field of the currency and that fireAction handleCurrencyChangeEvent action method is called, right?

    Instead of using dtlVo.getCurrentRow, use the code below:

    public void handleCurrencyChangeEvent(String eventRowSourceParam)
      {
      OAViewObject pvo = (OAViewObject)findViewObject("xxCurrencyPVO1");
      OARow row = (OARow)pvo.first();
    
      OAViewObject dtlVO = (OAViewObject)findViewObject("xxEcreditCardDtlVO1");
    
      //OARow dtlRow = (OARow)dtlVO.getCurrentRow();
      OARow dtlRow = (OARow)this.findRowByRef(eventRowSourceParam);
    
      String  currency = (String)dtlRow.getAttribute("CurrencyCode");    // NULL POINTER EXCEPTION
    
      if ((currency == null) || ("AED".equals(currency)))
      {
      row.setAttribute("ExchangeRateTypeRender", Boolean.FALSE);
      row.setAttribute("ExchangeRateDateRender", Boolean.FALSE);
      row.setAttribute("ExchangeRateRender", Boolean.FALSE);
      }
      else
      {
      row.setAttribute("ExchangeRateTypeRender", Boolean.TRUE);
      row.setAttribute("ExchangeRateDateRender", Boolean.TRUE);
      row.setAttribute("ExchangeRateRender", Boolean.TRUE);
      }
      }
    

    In the controller:

    if((ADD_ROWS_EVENT.equals(event)) && "AdvTblRN".equals(pageContext.getParameter("source")) )
    {
      am.invokeMethod("createDetailRow",null);
      am.invokeMethod("initPVO");
    } //**End Add Row Button**
    else if ("currCodeChangeEvent".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
    {
      String eventRowSourceParam = pageContext.getParameter(EVENT_SOURCE_ROW_REFERENCE);
      Serializable[] params = {eventRowSourceParam};
        Class[] paramTypes    = {String.class};
      am.invokeMethod("handleCurrencyChangeEvent",params, paramTypes);
    }
    

    3. Why do you call initPVO when it is clicked on the Add line? Are you calling not just in the PR?

    You could call it once in the PR and let. When you call it PR, you may need to remove the handleCurrencyChangeEvent of this method call.

    See you soon

  • Performance problem with the guest operating system

    Hello gurus - I have one of the most unusual questions, I ran into a few time.   Here it is:

    I have a guest w2008R2 OS - installed in a 5.1 version of VM 7 vSpherer - which has an Emulex LPe 12002-E 8 GB dual HBA port is assigned to the as 2 PCI (1 device per port) via DirectPath devices

    The guest operating system has an application that performs backup tests.   WWPN of the HBA is zoned in the fabric and declared in the interface of Compellent Storage Center and everything is good here. the application creates a replay of a volume, mount it as a drive, read all the blocks, then dismantles and moves then repeat the process with what ever additional volumes should be safeguarded.   It is so cool I have do this with a VM right and not a physical host?  (would be cool if I had work NPIV but that's another story, not with technology HBA vendor support...)

    So, what's the problem?   Well, the bed the mounted disk backup will work extremely slow as slow as 5MB\sec flow, then during any other activity takes place on the system the flow jumps up to 150MB\sec all of a sudden and will continue to run fast for a long time and finish jobs on time with each work taking a little more than an hour.  But when the slow going the same work (all jobs are the same, they are simply by reading all the blocks of a bunch of 200 GB volumes and wrote a set of NULL value, do not forget this is just test) takes up to 10 hours to complete.

    I think that what is the culprit?   POWER MANAGEMENT.

    I have just about each performance counter and the journal of events known to man and I don't see anything abnormal on the table, ESXi virtual machine, nothing.  But what I see in the newspapers is any kind of activity that could happen in a transparent manner to save energy.

    FACTS on this case:

    -Reservation of memory is defined (it must be for directpath otherwise, you can't power on the virtual machine)

    -Booking CPU - has not been defined before an hour ago, I gave her just a small reserve for this rule, so I do not know if this will help alleviate the slow flow, or have an effect on what I think is a question of power (unit linked) management

    -windows power management is set to high performance never-ever - but not until an hour there doesn't I changed advanced settings for USB Disabled------turned off.  PCI peripheral energy saving setting was already off.  Which is in contradiction with my theory.  But maybe, just maybe, something is broken somewhere, or could be a bug... blah blah blah

    -the HBA, Emulex, as it appears in Device Manager in the guest OS doesn't have a power management tab to disable the feature, I don't see that the adapter VMXNET3 had this tab, and I turn off the power save setting to be conservative, do not think that it was the culprit, but as there is no real data running through the NIC.  The data is simply to be read from the disk mounted, not copied on any wire Ethernet.  never the less, in the Emulex properties is a Details tab and a selection of power data, and performance data indicate you what power mode, the device is, as well as feeding supported systems.  D0: full power, but D3, which shows as supported by the device, is an energy saving mode.   I could not yet attend the setting at the time of slow activity, my good intention as soon as possible. He is currently shooting in D0, full power.

    This is so what I have to offer on this, I hope that its just...   If I'm missing something, or if others have experienced this massive loss of unknown flow without reason and have resolutions, please share.

    If there is a way for me to disable power on the Emulex HBA management inform you please, I don't mind if I stop to enter the firmware, if that was even possible.  But if possible I would disable it immediately before any new tests are executed.

    The root cause of this issue has never been identified by VMware support which for me is a question of ugly.  Reservation of CPU for the VM using directpath IO with HBA installed in it corrected the problem.  I'd be leary with direct path IO.

  • A fundamental question/problem with the like undefined array element

    Hello everyone,

    Thanks for looking at my problem. I am very new script and javaScript, and I encountered a strange problem. I always try to solve all my problem myself, with documentation (it helps to learn) or as a last resort with the help of google. But in this case, I'm stuck. I'm sure its something very simple and elementary.

    Here I have a code that simply loads a text file (txt), load the contents of the file in a "var glad." This summary text file a font family name, every name on a new line, as:

    Albertus

    Antenna

    Antique

    Arial

    Arimo

    Front

    Barber1

    Barber2

    Barber3

    Barber4

    Birch

    Blackoak... .etc

    Now I hollow the variable content of loop, extract each letter and add it to the list '[i]' table. If the character is a line break the list [i] table adds another element (i = i + 1); That's how I separate each name in its own element of array.

    The problem I encounter is, when I have hollow loop table fontList and $.writeln (fontList [i]) is the result in the console :

    undefinedAlbertus

    undefinedAntenna

    undefinedAntique

    undefinedArial... etc.

    I don't get serious, where the undefined comes? As far as I tested each digit to be added to the array element, I see nothing extraordinary.

    ----------------------------

    ----------------------------

    Here is my code:

    #target illustrator

    var doc = app.documents.add ();

    Open the file

    var myFile = new File ("c:/ScriptFiles/installedFonts-Families.txt");

    openFile var = myFile.open ("r");

    check if it is open

    if(OpenFile == true) {}

    {$.writeln ("the file has loaded")}

    else {$.writeln ("the file does not load, check the name or the path") ;}}

    load the contents of the file into a variable

    var content = myFile.read ();

    myFile.close ();

    var ch;

    var x = 0;

    var fontList = [];

    for (var i = 0; i < content.length; i ++) {}

    ch = content.charAt (i);

    If ((ch)! == (string.fromCharCode(0)) (10))) {}

    fontList [x] += ch;

    }

    else {}

    x ++;

    }

    }

    for (i = 0; i < fontList.length; i ++) {}

    $.writeln (fontList [i]);

    }

    doc. Close (SaveOptions.DONOTSAVECHANGES);

    -----------------

    Thanks for any help or an explanation. If you have any tips on how to improve my practices or any suspicion, please do not hesitate to say. Thank you

    Hi vladac54380629,

    better, you try something like this:

    #target illustrator
    
    //var doc = app.documents.add(); 
    
    //open file
    var myFile = new File ("c:/ScriptFiles/installedFonts-Families.txt");
    var openFile = myFile.open("r"); 
    
    //check if open
    if(openFile == true){
        $.writeln("The file has loaded")}
    else {$.writeln("The file did not load, check the name or the path");} 
    
    //load the file content into a variable
    var fontList = []; 
    
    var content = myFile.read();
    fontList = content.split ("\n")
    myFile.close(); 
    
    for ( i = 0; i < fontList.length; i++) {
       $.writeln(fontList[i]);
      }
    
    //doc.close (SaveOptions.DONOTSAVECHANGES);
    

    Have fun

    A note:

    The real font names may be different from your own list for example:

    Arial! = ArialMT

    Birch! = BirchStd

    Blackoak! = BlackoakStd

  • Filter a column with the value of another

    Hello. Hope someone can help with this... On my search page, I want to use the value of the first list/drop-down menu to filter the values of the second list/menu. I use PHP and DW 8.0.2.

    Example: The first column has each of the 50 States. second column has 3 000 counties. If a user selects New Jersey, I want to just 21 NJ counties to appear as options in the second menu downwards rather than 3 000 counties.

    First Recordset works very well for the States. But in my second recordset, I say 'select distinct County of the said County WHERE AS var1'... and var1 is $recordset1 [County]. But the 2 column is empty. How can I actively pass the value of the first column in the second while the user is still on the same page?

    Sandman

    >>
    Assuming that your table has a field named "State":
    «select County of States WHERE state = "var1""

    You can use this solution when the first menu page 1 and the second menu on page 2 (IE passing the value of a query on page 2), but as assumingly, you need to have this functionality within a single page, basic need based on a javascript solution 'drop-down menus of dynamic load' to load the menu2 - options "in situs.

    There is an extension for Dreamweaver stand alone for this on the site of Tecnorama , that also wants to work without the relationships between the tables, in other words, with the data in a table, which matches your scenario.
