How to display the line empty as a line with null values

Hi all

Pls advise me if it is possible to use a single query statement to display
Empty row (i.e. not a single return line) as a line with null values.

For example,.

Select the names of names_mst whose name = "sgasfgs".

Result:
Names of
=====
< null >

Hello
If you desire to join external to double, as shown below, you still get at least a line of production

SELECT  nm.names
FROM            dual
LEFT OUTER JOIN names_mst   nm  ON nm.name='sgasfgs';

  • Add filter slot table form to show the lines with null values

    Hello

    I have a tabular presentation where we need to add a filter with two values (selection list) so that if one of the columns in a table (column1) is zero, then I need to display all records where column1 is null.

    I was wondering how do I put this in the Source of tabular forms where condition. This filter has only two values,

    All the
    NULL for the error

    So when the user selects all, then all the records in the table are shown
    If the user selects 'Value Null in error', while the records where Column1 is null will be shown

    For example
     column1        column2
                           A
                           B
          1               C
          3               D
     
    If the user selects, then

    all four files will show up. Else, only the first and the second will be returned.

    Thank you

    Hi, Ryan.

    Try a static LOV like this

    STATIC2:;,--- All ---;--- All ---
    

    and a Where clause, like this

    where column1 is null or :p1_filter like '%%'

  • How to display the line number in the form?

    Hi guys,.
    First I fll you in the story so far...

    I have a block of data in database named: V_PAYUPLOADHEADER_HP, in the property palette I put in order by facility and warehouse.

    I want to display the line number for each record of recoveries, so I do: V_PAYUPLOADHEADER_HP. NUMB, which will contain the line number.


    Here are some methods I've already tried:
    -First I tried to make a database of field element = O, column name = ROWNUM.
    The result is the jump of integer (1, 2, 5, 3, 4 etc. instead of 1, 2, 3, 4, 5) I think it is because of the agenda that I set.
    I have to keep this order by setting, so I look for another way to display the rownum.

    -Then I tried to set the data item = N, column name = null, mode of calculation = formula, formula =: system.trigger_record.
    When I run the value of: V_PAYUPLOADHEADER_HP. NUMB is 1. For all recovered records is 1, 1, 1, 1 instead of 1, 2, 3, 4.

    -J' also tried to use the trigger after QUERY attached to the block.
    In relaxation, I have this code:
    : V_PAYUPLOADHEADER_HP. NUMB: =: system.cursor_record;
    When I run the value of: V_PAYUPLOADHEADER_HP. NUMB is 1. For all recovered records is 1, 1, 1, 1 instead of 1, 2, 3, 4...



    Is there something I missed?
    What can I do to display the rownum?

  • How to display the "Add a contact" dialog box with the non-empty fields?

    On the BlackBerry, I want to display a dialog box 'Add a contact' with some fields filled.

    I assumed would work the following code:

    Contact BlackBerryContact = mContactList.createContact ((BlackBerryContact));

    populateSomeFields (contact);

    AddressBookArguments args = new AddressBookArguments (AddressBookArguments.ARG_NEW, contact);

    Invoke.invokeApplication (Invoke.APP_TYPE_ADDRESSBOOK, args);

    but no way. If I invoke with ARG_NEW a completely EMPTY fields are displayed.

    If I invoke with ARG_COMPOSE an IllegalArgumentException is thrown. Is it possible that I can show 'Add a contact' with some informed fields?

    just as an idea: maybe you have to make contact before the opening of the new message notice?
    otherwise it is not possible, you will need to write your own GUI to change the fields in contacts.

  • How to follow the line with the vision of the webcam and move along in this

    Hello world

    I have a question that I can't really find a topic about it.

    Currently, I had made my rover robot wireless control using a 3-axis joystick and works perfectly.

    But I want to add some features to the vision on board the rover system.

    I'm doing the webcam to detect a black line on a white background, and then, he moves just independently along the the line black.

    The thing is that I only know abit about installation in a vision... So, if anyone here able to guide me on the way?

    I use filtering color or color matching or model of a match?

    How to make sure that the black line remains in the middle of the vision? (Eg. moving itself at the center of the line within his vision)

    How can I control the engines using the achievements of the vision of the foregoing?

    Hey,.

    Your questions:

    I use filtering color or color matching or model of a match?

    Pattern Matching or Color Pattern Matching would slow down.

    I would use a 1 d Simple edge detection that returns the coordinates and the edge angle.

    How to make sure that the black line remains in the middle of the vision? (Eg. moving itself at the center of the line within his vision)

    You must control your motors that for example the angle is 0 degrees or 90 degrees (depending on your coordinate system) all the time.

    How can I control the engines using the achievements of the vision of the foregoing?

    This robot manual should tell you how to control the motors.

    Hope this helps,

  • How to display the list of components in ultiboard 10?

    The DRC report the errors where the components that are no longer in the design have been removed. How to display the list component and then remove them from the netlist to stop this?

    Ultiboard reported missing errors of component (part 'X' is not about design) because the part is always referenced by a net. To fix this, you must remove the part of the net. Following the steps below to remove the part form the net.

    1 tools > Netlist Editor

    2. for each network that the part has been connected to, select the Net (upper-left).

    3. Select the tab of pine trees, select the part and it is the PIN in the dialog box, then click on remove

    The problem is when the part is removed, I see no easy way to determine the threads you need to remove the part of. I entered this as a feature request to make this easier, but as a workaround, you can put part and say Ultiboard what the missing part, then search the net names on the pins and remove the part of these pins

    1 place a piece with a lot of pine trees (for example the part that was removed, or for example through Hole technology > Connectors > SIL & headers > HEADER2X9). When you place the part, make sure that the RefDes matches the RefDes of the part which has been removed.

    2. once the room is placed, you should see rats nest lines that connect the part to the nets.

    3 Zoom on the pins. You should now see the net name on each of the axes. For each of the pins connected, remove it from the net as described above.

    4. remove the part that you placed.

  • How to choose the line PFI to use on the port of the 5761?

    I understand that the VIDEO that I use on my DAC 5761 allows me to access 8 PFI lines.  However, when I access my 5761 devices in the project window by clicking the "+" next to the name of the module, I see that 'PFI Input' and ' output PFI.  I tried to get this to send a signal in the past, but I have been unable to determine how to select the line PFI I want to use.   How can I select the PFI line?

    Any ideas?  I was able to get the my AWG PFI (5422) for work and it is amazing.  I want to order an attenuator digital step for a ground penetration radar that I develop.

    Your time and your help is very appreciated.

    PS: I have worked with this PXI system (chassis, embedded controller, FPGA digitizer 5761 and AWG) for 1 year and I am afraid that it is time to learn this one way or another.

    Good day!

    -Daniel

    I found the solution. In addistion to the node which is visible in my previous post, there must be a node to enable PFI write with an entry of decimal number indicating the line is activated. Then, there must be a node PFI active connector, set to true. Not sure if the node of the latter is really necessary, however. Otherwise above examples should work as is.
