Get unique values from an xml table

I have an xml file and I would like to create a table of all the unique values of one of its nodes.

The xml file is called pntxml and the node is pntxml.row.Category where the category is where I would like to create a table of all the unique values.

I was working through this and would first create an array of all the values in the category in iterating through the xml and pushing these values in a separate table.  When I try to push each entry in a table I get an error or

TypeError: Error #1009: cannot access a property or method of a null object reference.
at NAPA_fla::MainTimeline/sortXml()

var catArray:Array;

function sortXml(event:Event):void{
for (var i:int = 0; i< pntxml.row.length(); i++){
     tmpCat=pntxml.row[i].Category;
     trace(tmpCat);
        catArray.push(tmpCat);           
}
}

Anyone has a suggestion for the best way to get at this problem?

Thanks in advance,

Josh

Your catArray does not exist because you said only she, you have not created an instance of this...

var catArray:Array = new Array();

  • Getting a value from selectonechoice

    Hello

    I use Jdeveloper 11.1.1.6

    My requirement is as below

    I have a component selected only one option, which displays a list of values.

    The user selects a value from the list of value and clicks the command button, and then the input field should be updated with the

    the value that is selected in the list.

    To do this, I wrote the code (no components company involved / only ADF faces) below

    I am able to get the list of values and post it on my page. For the rest of the game, I am not able to guess.

    I put selectoncechoice partialtriggers for buttons and the text in field

    All I need is the java code for getting the selected value and by attaching it to the text field.

    Can you help or guide me on this...

    Bean:

    The list < SelectItem > tempList.

    {} public void settempList (list < SelectItem > tempList)

    this.tempList = tempList;

    }

    public list < SelectItem > gettempList() {}

    If (tempList == null) {}

    tempList = new ArrayList < SelectItem > ();

    tempList.add (new SelectItem ("t1", "Item 1"));

    tempList.add (new SelectItem ("t2", "Item 2"));

    }

    Return tempList.

    }

    Hello

    If you see:

    You must set a value for the selectOneChoice component. You add a new variable in your beans to use it to store your selectedItem. Then your output text should also reference the same attribute in its value field.

    Try to add in your bean:

    String mySelection;

    public String getMySelection() {}

    return mySelection;

    }

    {} public void setMySelection (String, string)

    mySelection = string;

    }

    value = "#{ValuesBean.mySelection}" label = "Custom List" id = "soc1" contentStyle = "make weight:"BOLD"; color: Green; » >

  • How to get the value of row current table when press the button submit

    Hello

    I want to get the current value of the SuccessionPlanId line which is part of the column in a table that is advanced.

    I created a (created using customization, from action through CO) button in the table as column, so each line with a single key, if I press the button of the first line means so I want to extract the first line SuccessionPlanId and if it's the 3rd way so I want to get the value of the value of the third row.

    How in the post of controller?

    Please answer soon, its urgency.

    Thanks in advance,
    SAN

    OK, need to go with a delicate way,

    1.) create a new table with Jdeveloper and there shud be a replica of the room once except the button submit newly added, pls note button type shud be present the type of button.

    2.) hide the existing table area and create a new stacklayoutbean.

    (3.) this stacklayout bean will have the property to extend, you give the full path of the new custom of advanced table box.

    Now you should be able to get the reference of the line during the click on the "submit" button

  • How can I get a value from a function from pl/sql by OADBTransaction

    Hi all
    Hope you will be fine.
    as we know, we can get a sequence by this code value:

    Transaction OADBTransaction = getOADBTransaction();

    Vendor ID is obtained from the table sequence
    Number supplierId = transaction.getSequenceValue ("FWK_TBX_SUPPLIERS_S");

  • Select values from the db1 table and insert into the DB2 table

    Hello

    I have three databases oracle running in three different machines. their ip address is different. among the DB can access databases. (means am able to select values and insert values into tables individually.)

    I need to extract data from the DB1 table (ip say DB1 is 10.10.10.10 and the user is DB1user and the table is DB1user_table) and insert the values into DB2 table (say ip DB2 is 11.11.11.11 and the user is DB2user and table DB2user_table) of DB3 that is to have access to the two IPs DB.

    How do I do this

    Edited by: Aemunathan on February 10, 2010 23:12

    Depending on the amount of data must be moved between DB1 and DB2, and the frequency at which this should happen, you might consider the SQL * COPY more control. I think it's very useful for one-off tasks little, so I can live within its limits of the data type. More http://download.oracle.com/docs/cd/E11882_01/server.112/e10823/apb.htm#i641251.

    Change some parameter of sqlplus session are almost mandatory in order to get decent transfer rates. Tuning ARRAYSIZE and COPYCOMMIT can make a huge difference in flow. LONG change may be necessary, too, depending on your data. The documentation offers these notes on use:

    To activate the copy of data between Oracle and databases non-Oracle, NUMBER of columns is replaced by DECIMAL columns in the destination table. Therefore, if you are copying between Oracle databases, a NUMBER column with no precision will become a DECIMAL column (38). When copying between Oracle databases, you must use SQL commands (CREATE TABLE AS and INSERTION), or you must make sure that your columns have a specified precision.

    SQL * the VALUE LONGER variable limits the length of the LONG column you are copying. If all LONG columns contain data exceeds the value of LONG, COPY truncates the data.

    SQL * Plus performs a validation at the end of each successful COPY. If you set the SQL * variable more COPYCOMMIT DEFINED to a value positive n, SQL * Plus performs a validation after copying all lots n of records. The SQL * Plus ARRAYSIZE variable SET determines the size of a batch.

    Some operating environments require that the service names be placed between double quotes.

    From a SQL * Plus term on DB3, can resemble the command to move all content from my_table in DB1 to the same table in DB2

    COPY from user1/pass1@DB1 to user2/pass2@DB2 -
INSERT INTO my_table -
USING select * from my_table

    Note the SQL code * more line-continuation character ' - '. It is used to escape the newline character in a SQL * Plus command if you do not have to type all on one line. I use it all the time with this command, but I can't locate the documentation on that right now. Maybe someone else can put their finger on it.

    There are other ways to accomplish what the command copy and it is not without its quirks and limitations, but I find that there is usefulness in an Oracle Toolbox.

    I need to retrieve the Id of the node FacilitySiteInteraction - in this case, the values are 78104 and 78105.

    I tried to use extractvalue just, but he hesitates with error ORA-19025.
    select extractvalue(x,'//FacilitySiteInteractionList/FacilitySiteInteraction/Id','xmlns="urn:WA.Ecy.ADS.FacilitySite.Services"')
from my_tab;

ERROR at line 2:
ORA-19025: EXTRACTVALUE returns value of only one node

-- note: column my_tab.x is an xmltype data type
    If I use just extracted I see there the rub
    select extract(x,'//FacilitySiteInteractionList/FacilitySiteInteraction/Id',
'xmlns="urn:WA.Ecy.ADS.FacilitySite.Services"')
from my_tab;

<Id xmlns="urn:WA.Ecy.ADS.FacilitySite.Services">78105</Id><Id xmlns="urn:WA.Ecy.ADS.FacilitySite.Services">78104</Id>
    The format of the XML document does not have to consider another records/lines.

    So, the next thing I tried was using the value of the iterator:
    select extractvalue(x,'//FacilitySiteInteractionList/FacilitySiteInteraction[2]/Id',
'xmlns="urn:WA.Ecy.ADS.FacilitySite.Services"')
from my_tab;

78104
    The downside of what I see is that I must first enter the TotalRowCount value and then more wrap XML Document TotalRowCount times
    in order to get these values. So I was wondering if it is a more effective approach to enter these data?

  • Need to get Max Value day in a table with hourly data of SQL

    I have a table "tmp" with these columns:

    ID, date, time, value

    I want to get the 'time' when 'value' max is reached in each 'day '.

    the query:

    "SELECT id, day, hour, max (value) from group tmp by id, date, time"
    does not return the desired lines.

    You have an idea to get what I want?

    Maybe this:

    with tmp as
( select 1 id, trunc(sysdate) day, 10 hour, 100 value from dual union all
  select 2 id, trunc(sysdate) day, 11 hour, 110 value from dual union all
  select 3 id, trunc(sysdate) day, 12 hour, 120 value from dual union all
  select 4 id, trunc(sysdate) day, 13 hour, 130 value from dual union all
  select 5 id, trunc(sysdate-1) day, 10 hour, 100 value from dual union all
  select 6 id, trunc(sysdate-1) day, 11 hour, 90 value from dual union all
  select 7 id, trunc(sysdate-1) day, 12 hour, 150 value from dual union all
  select 8 id, trunc(sysdate-1) day, 13 hour, 100 value from dual )
Select ID, Day, Hour, Value
From Tmp
Where (Day, Value) IN (
Select Day, Max(Value)
From Tmp
Group by Day)

  • To get the value from the user input

    Hi guys,.

    I have a .sql file, I need to get the feedback from the user and date to treat more end passing as a parameter in the procedure

  • Getting a value from a text of entry in backing bean element

    I created a component of entering text on a page where I will enter a number, adjustment of Autosubmit as true. ValueChangeListener property is defined as #{test.displayTable} where displayTable is a method defined in managed bean test.

    Now I know to extract the value entered in the text input component by creating a RichInputText variable in the advanced properties.

    But in case the Advanced property is empty, then how I'll be able to recover the value of it? This is the code. I'm not able to get the value entered in the component. I can not even find any method getvalue for her.
    FacesContext facesContext = FacesContext.getCurrentInstance();
UIViewRoot root = facesContext.getViewRoot();
RichInputText inputText = (RichInputText) root.findComponent("it1");  // it1 is the id of the input text component
System.out.println("inputText: "+inputText);
    On the use of my statement, is out getting generated, whereas I had entered in 90.
    inputText: RichInputText[UIXEditableFacesBeanImpl, id=it1]

    Hello

    Always mention your JDev version.

    If you use a valueChangeListener for the field, you can get the value using valueChagedEvent.getNewValue ().

  • I can't get a value from a list of CFDIRECTORY.

    I avoided the madness all these years, but this issue was finally on the brink.  My placement in an institution is in your hands.

    I try to get the name of a specific directory to the list of directories produced by action CFDIRECTORY = 'list '.  But everything I try fails in one way or another.  Bascially, I can't get the value of the structure - even if the code IS the value - because he thinks that the value is meant to be a field or a key.  (The server running CF8).

    These lines of code work fine:

    <!-do and loop through the list of local directories. ->

    < CFSET LocalDirectoryList = "" > "".

    < action CFDIRECTORY = 'list' name = "LocalDirectoryList" TYPE = "dir" directory = "#PathOfLocalFolderToCopyToRemoteFolders #" >

    < CFIF IsDefined("LocalDirectoryList.RecordCount") AND GT LocalDirectoryList.RecordCount '0' >

    < request CFLOOP = "LocalDirectoryList" >

    Now comes the killer.  I want to set a variable whose value is the name of the local current directory - in other words, the value of LocalDirectoryList.Name for each loop the loop.  But if I try to access LocalDirectoryList.Name as a string variable simple, the way I usually for a query string variable-

    < CFSET ThisLocalDirectory = LocalDirectoryList.Name >

    -I get a message "you have attempted to dereference a scalar variable of type class java.lang.String as a structure with members.

    However, if I treat the "LocalDirectoryList.Name" as a structure and try to deconstruct with one of the following conditions.

    (1) < CFSET ThisLocalDirectory = Evaluate (LocalDirectoryList.Name) >

    (2) < CFSET ThisLocalDirectory = ' #Evaluate (LocalDirectoryList.Name) # ">

    (3) < CFSET ThisLocalDirectory = ' #StructFind (LocalDirectoryList, Name) # ">

    (4) < CFSET ThisLocalDirectory = StructFind (LocalDirectoryList, name) >

    (5) < CFSET ThisLocalDirectory = ' #Evaluate (StructFind (LocalDirectoryList, name)) #">".

    I get either "horizons variable is not defined" (for 1 or 2) or "the specified key, backgrounds, does not exist in the structure" (for 3, 4 or 5).

    In this case, the name of this directory is "horizons."  If the value I'm looking for do EXIST in the structure of 'LocalDirectoryList '.  And the code IS that IT is.  But he thinks it is the NAME of a key, rather than the VALUE of the key.

    Note: The addition of the attribute, listInfo = "Name" to the CFDIRECTORY tag limit fields returned, or key, "Name", but LocalDirectoryList.Name is still a structure, and I still get the same results.

    I'll be the next cuckoo in the cuckoo's nest?  Or can you save me and keep me sane?  My fate is in your hands.

    Thank you!

    You don't need the evaluate statement (in fact you probably shouldn't need to use than ever at that time). And inside the loop of your application, you can send all your query without prefix fields.

    When in doubt, empty your query of cfdirectory.

  • How to get the value of an af:Table SelectOneChoice

    V11.1.2.4.0 - JSF JDeveloper

    Greetings,

    Im having a problem getting a column value that is an object of a select choice.

    This isn't a common problem, as I actually did something that others so please follow my problem

    Description and if you have questions/answers please answer below.

    I create a database view that returns me 3 columns, say TestValue TestCode, TestDescription.

    I added an extra temporally column in my OV and called Temp.

    I drag / drop my OV, remove value Temp and its position of the column, I drag / drop a LOV, who comes from a different view.

    that shows me the doctor name & first name and identification number of the back doctor select a value of choice.

    I'm using a function that go through the iterator, gets the lines and save them in the database (no matter how).

    The problem is my selectonechoice, are not row.bindings.DoctorId.InputValue, but the links. DoctorId.InputValue instead, so I can retrieve value selectonechoice of the current line.

    Then when my loop is finished and insert rows in my database, id of the doctor of the line everyone is the same as the binding do not change through the loop.

    I don't know how to add value to the current line select only one option to use the correct value to each loop of the line.

    Here is my loop function:

            DCBindingContainer bc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
        DCIteratorBinding iterator = bc.findIteratorBinding("ExaminationsIterator");
        DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();


         RowSetIterator rsi = iterator.getRowSetIterator();  
         int i=0;
         
        OperationBinding save_exams = bindings.getOperationBinding("SAVE_EXAMINATION");
        OperationBinding save_exams_commit = bindings.getOperationBinding("SAVE_EXAMINATION_COMMIT");
           
        try{
         while(i < rsi.getRowCount()){
             
             Row r = iterator.getCurrentRow();
                             
             save_exams.getParamsMap().put("CodeTest", r.getAttribute("CodeTest"));
             save_exams.getParamsMap().put("Dates", r.getAttribute("Dates"));   
             save_exams.getParamsMap().put("CodeId", orderid.getValue());   
             save_exams.getParamsMap().put("Times", r.getAttribute("Times"));    
             save_exams.getParamsMap().put("DoctorId", resolveExpression("#{bindings.DoctorId.attributeValue}").toString()); 
             save_exams.getParamsMap().put("IdPatients", patientid.getValue());   
             save_exams.execute();
             rsi.next();
             i++;
         }
        
            save_exams_commit.execute();

    I get the connection id of the current doctor and the value of the rows no.

    Can you help me on this please?

    I created a work around solution, until an expert that I come with a more advanced solution.

    (1) I add a LOV at the id of the doctor on the view target object.

    (2) on the duration, I fill my view of database

    3) go through all my DB view iterator lines

    (4) appends each line on the View object target (missing id of the doctor, because I want it to be on common language runtime) & commit lines

    (5) after the loop ends and the target object from view show me results from the view of DB, I choose the runtime id of the doctor and commit the changes if

    the new lines, with the new update will be finally filled to the database.

    I hope this helps if anyone has a similar task.

    Please let me know if you find a more direct solution, this work with 2 tables to fill 1.
