display the value zero

The first query shows that there is no amount present in the warehouse
SQL>  select sum(received_qty) - sum(transact_qty) - sum(transit_qty) from ship_1 where matid='52616
' and placefrom='Jeddah MC';

SUM(RECEIVED_QTY)-SUM(TRANSACT_QTY)-SUM(TRANSIT_QTY)
----------------------------------------------------
The second query shows the warehouse got about 35 pieces of a specific material.
SQL> select  sum(received_qty) - sum(transact_qty) - sum(transit_qty) from ship_1 where matid='8521'
 and placefrom='Central Store';

SUM(RECEIVED_QTY)-SUM(TRANSACT_QTY)-SUM(TRANSIT_QTY)
----------------------------------------------------
                                                  35
In the form for the first query, I want to display the value 0 (zero), how this can be done...?

Hello

Using NVL as

select  NVL (sum(received_qty) ,0) - NVL (sum(transact_qty),0) - NVL (sum(transit_qty),0) from ship_1 where matid='52616
' and placefrom='Jeddah MC';
 

Kind regards

    You cannot reference variables as you did and get the value of the variable. Use pretty collection.

    set serveroutput on size 2000

  • Obtaining the value zero

    Hi all

    I extend the standard page controller

    I try to capture the value of an element on the page, but I get the value zero.

    Here are the syntaxes I tried

    String s = oapagecontext.getParameter ("EmployeeNumber");

    and

    String s = (String) oapagecontext.getSessionValue ("EmployeeNumber");

    Please suggest me.

    Kind regards

    Sangu

    It does not work like that,

    There are two ways to get the value of the entire area of text in code and also depends on in what method (processRequest or processFormRequest) you want to capture the values.

    Method 1: -.

    OAMessageTextInputBean employeeNumberBean = (OAMessageTextInputBean) webBean.findChildRecursive ("EmployeeNumber"); assuming that the id of the TextField is EmployeeNumber

    String EmployeeNumber = employeeNumberBean.getValue (pageContext) m:System.NET.SocketAddress.ToString ();

    or the best way is to always get with the original Version instead of the bean - here is the code to browse the vo, you just have to identify the vo that is attached to the input area and where your employeeNumber is present and replace this vo name in the code below

    BankAccountsVOImpl BankAccountsVO = (BankAccountsVOImpl) am.findViewObject ("BankAccountsVO");

    Line BankAccountsVORowImpl = null;

    int fetchedRowCount = BankAccountsVO.getFetchedRowCount ();

    RowSetIterator rowIterator = BankAccountsVO.createRowSetIterator ("iteraTor");

    If (fetchedRowCount > 0)

    {

    rowIterator.setRangeStart (0);

    rowIterator.setRangeSize (fetchedRowCount);

    for (int count = 0; count)< fetchedrowcount="" ;="" count++) ="">

    line = (BankAccountsVORowImpl) rowIterator.getRowAtRangeIndex (count);

    entity = row.getAttribute1 ();    -instead of this line, here you can write to row.getEmployeeNumber if it is an attribute of the vo

    majorOffice = row.getAttribute2 ();

    Office = row.getAttribute3 ();

    }

    }

    rowIterator.closeRowSetIterator ();

  • How to display the value of the column

    Oracle 10g on Linux

    I want to display the value of the id column in the table of www if count (distinct id) is 1. The following query is fine except that it does not display the value of the column ID help, please.
    SELECT count(distinct id)
                   FROM www c

                  having count(distinct id) = 1                                                

    I think you can use MAX in this case

    SELECT max(id)

  • Display the values of the Page element in HTML table

    Hi all

    could you please help me with the below? I want to have a table in the HTML area and to display in the table of elements of the Page of the page.

    I got the code like this:
    {
    < table >
    < tr > < td > & P1_ECEMEA_ASSISTANCE < table > < /tr >
    < tr > < td > & P1_ECEMEA_WIP < table > < /tr >
    < /table >
    }
    It shows the element of the Page names in the form of text, not the values.

    However, this code without the tags table:
    {
    ECEMEA request for Assistance of the CQT: & P1_ECEMEA_ASSISTANCE.
    ECEMEA CQT Work in Progress: & P1_ECEMEA_WIP.
    }
    Works and Page element values are displayed.

    Is it possible to display the values of the Page element in the HTML table at all or should I use a different method to show the values in a table? The above is only an excerpt of the code. I need to display about 30 items in Page, put in shape in a table with headers.

    Please let me know what kind of region is the best to use, or if I have to use only a few symbols of escape in the table code...

    Thank you and best regards,

    Vladimir

    Vladimir,

    Looks like you're missing the period after the substitution variables.

    {
    
    &P1_ECEMEA_ASSISTANCE.
    &P1_ECEMEA_WIP.
    }

  • Need help displaying the value of field in another!

    I have a problem, I'm sure is simple but I can't understand it.

    I would like to create a field that displays the value of a field point selecteed in drop down. For example, I created a drop down menu which has 3 times that I have assigned values to each:

    Items in drop-down list

    point: Unlimited time export assigned value: 4 000,00

    point: 8-hours coverage export value assigned: 3,000.00

    point: 5 hours Covrage export value assigned: 2,000.00

    This drop-down list is named "CoverageTime".

    I want to create a text called 'Price' field that will display the value of the selected 'CoverageTime' element drop-down list.

    For example, if I chose "Unlimited" (which I have highlighted as 4,000.00) in the drop-down list, the 'Price' of text field should display the value of 'CoverageTime' of 4 000,00.

    As you can see in my screenshot, I have selected ' Unlimted Time'. The value that I put to this element from the drop-down list is 4,000.00. But the price text field does not the value of the element "Unlimited time", selected in the drop-down list.

    How to make this happen? (Sorry for the picture on the side)



    I'm not sure what you mean about #1 (there is nowhere where to put the code in the tab Options), but it's okay because the second is on the right track. But to set the value of the field, assign anything you want event.value. So the correct code for the custom script to calculate the price of the text field:

    The value of this field for the price of the value selected from the drop-down list

    Event.Value = getField("CoverageTime").value;

  • Display the values of variables

    Hello David,.

    It's the way I am especially debugging advanced actions by inserting the variables used in a text of the legend Rick indicates. A long time ago that I wrote two articles on the basic use of variables, perhaps reading could specify:

    Use the power of variables without advanced actions

    Unleash the power of variables with advanced actions

    CAUTION: sometimes the update does not appear immediately. In another thread, I explained how you can refresh the contents of the enhanced TextArea widget that contains a variable that is filled with another widget on the same blade.

    OAMessageTextInputBean oa = (OAMessageTextInputBean) webBean.findChildRecursive ("ItemNo");
    oa.setAttributeValue (SItemNo);

    There is no such method as setAttributeValue for UI beans, this method is for VO, that is to say if you take a VO and VO a method object to set its attribute.

    Bean of the user interface, you will need to use method below,

    OAMessageTextInputBean oa = (OAMessageTextInputBean)webBean.findChildRecursive("ItemNo");
    oa.setValue(pageContext,SItemNo);

    You can use the following syntax in the header, html body, or the footor in your area:

    & P1_ITEM.

    And commercial front and end point are needed.

    If you want to format, you can use the following

    < span style = "make-weight: bold;" "color: darkblue" > & P1_ITEM. </span >

  • Displays the value of double type

    Hi - another crazy me today. With the help of v % of the SDK. Memorization of the GPS coordinates in a persistent storage which is fine. So want to show these results on a screen by updating a labelField with the value.

    the code below, printLn myTest displays a value of something as 42.1234 gets so thin value. However, with the code so I get Double.toString (myTest) cann't find symbol even though I java.lang. *; imported. If I remove this line of double.toString then it will compile, but throws an exception error when I try to display on the screen. Can someone help a newbie pls...

    If (persistentHashtable.containsKey ("LVFLat")) {}
    Double myTest is (Double) persistentHashtable.get ("LVFLat");.
    System.out.println ("# latitude =" + myTest);
    String finalLat = Double.toString (myTest);
    displayLVFLat.setText (myTest);

    You must read the documentation of the API and note the use of capital letters and tiny.  Capitals: the object, tiny, primitive.  Read the API done again and see what I mean.

    You want to replace this:

    String finalLat = Double.toString (myTest);

    with

    String finalLat = myTest.toString ();
