Thanks a lot for the reply
my table is like each employee has a supervisor and each employee has an organization_id and this organization id is the department we are talking about..
now...how to go about nowWhat you should do now is what Sri said earlier: post CREATE TABLE and INSERT statements for some sample data, and the results that you want from that data. You haven't given nearly enough information about your table or your requirements for anyone to help you yet. Also, say what version of Oracle you're using.
You'll better better replies sooner if you always provide this information whenever you have a question.
As Sri said, what is the "head"?
Is the "head" identified by some other columns (like job='MANAGER' in the scott.emp table)?
Is the "head" always an ancestor (that is, suprevisor, or supervisor's supervisor, or supervisor's supervisor's supervisor, or ...) with the same organization_id?
We're willing to share our knowlege of SQL. Are you willing to share your knowlege about the tables and your requirements? I don't think we can solve this without your help.

    My dad has itunes on his PC. I don't have my own but I recently have an iPad mini and an iPod. I don't know how to get songs onto itunes on the PC, using a different account or at least private/ separate..
    So how do I create a separate I tunes on a PC which already has itunes... Or if not can I plug my iPad to the PC and use itunes on my iPad, and drag mp3s from a computer.
    I'm not sure what the equivalent of a desktop is on the iPad.. And I don't actually know how to use the icloud either...
    Can anyone start me off, given it have a iPad and use of a PC - not mine with existing iplayer
    I do have spotify soundcloud so I could potentially use these.. If there is a route of getting either mp3's etc to end up on my iPad or iPod.

  • DATA TRANSFER - How to get a SINGLE SPACE in the downloaded file from UNIX?

    Hi Experts,
    Am sending data from SAP to UNIX/ Application server and text file on desk top as well.
    So, I am keeping a single character just SPACE at the END of each record.
    Then, When I see the downloaded text file, I found a SINGLE SPACE at the end of each record, fine.
    Then, by using CG3Y t code, I downloaded the UNIX file to my desk top.
    But, When I see this UNIX downloaded file from UNIX, I did NOT find any SPACE at the end of each record!!!
    Am doing every thing same in both cases.
    So,
    1 - Why its happening in case of UNIX file?
    2 - How to get a SINGLE SPACE  at the END in the downloaded file from UNIX?
    thanq

    Hi,
    I don't know if this works:
    perform SET_TRAIL_BLANKS(saplgrap) using 'X'.  
    perform SET_FIXLEN(saplgrap) using '0' '060'.   "put length of your line from-to
    ... download ...
    It will put space at the end of your line, according to the length.
    Hope it works,

    Hi,
    The events of BDT can be used to default some fields on creating a partner.
    For this create a function module for ISDAT. attach that event in BUS7.
    In the ISDAT funtion modulethe following code should be used.
    For example to set the nationality:
    I_BUSDEFAULT-NATIO = 'DE.
    CALL FUNCTION 'BUP_BUPA_FIELDVALUES_SET'
    EXPORTING
    i_busdefault = I_BUSDEFAULT

  • How to get values/data stored in the database into a list-item.

    how to get values/data stored in the database into a list-item.
    i tried to make a list item without any values assigned to it...but i got the below error.
    FRM-30191: No list items defined for required poplist.
    or
    FRM-32082: Invalid value for given item type.
    List EMPNO
    Item: EMPNO
    Block: EMP
    Form: MODULE5
    FRM-30085: Unable to adjust form for output.
    then according to some docs, i tried the the following for the trigger
    when-new-form-instance
    declare
         rg_name varchar2(40) := 'emp_rec';
         status number;
         groupid recordgroup;
         it_id item;
    begin
         it_id := Find_Item('empno');
         groupid := create_group_from_query(rg_name, 'select empno from emp');
         status := populate_group(groupid);
         populate_list(it_id, groupid);
    end;
    but yet didnt work... :(
    so how the heck do i get values fetched from the database table into the list item?

    for list items you need to values in the record group, one is the shown value and one is the returned value.
    Check out the online help for the populate_list built-in.
    You'll need something like select ename,ename from emp as the record group query.

    I'm french, my white Ipod4g 16gb has been stolen 2 days ago, I would like to know how to get it back thanks to the serial number! please

    You can't.
    Change your iTunes (Apple ID) password along with any other password that was stored in the iPod.  If any passwords are associated with credit cards, contact the CC company and get your card replaced (with a new number).  If any passwords are associated with a bank or any other savings institution, contact them also and discuss approprate action with them.
    The only real protection you have is with the personal information on the device rather than the physical device itself.  This requires action before the device is lost/stolen.  If the device has significant personal information, it should have a strong 8-digit (or longer) password AND be configured for automatic wipe in the event of ten consecutive incorrect password entries.

  • How to get a check box on the selection screen

    Hi all
    can any body tell me how to get a check box on the selection screen

    parameter: pa_check   as checkbox.
    To define the input field of a parameter as a checkbox, you use the following syntax:
    PARAMETERS <p> ...... AS CHECKBOX ......
    Parameter <p> is created with type C and length 1. In this case, you may not use the additions TYPE and LIKE. Valid values for <p> are ' ' and 'X'. These values are assigned to the parameter when the user clicks the checkbox on the selection screen.
    If you use the TYPE addition to refer to a data type in the ABAP Dictionary of type CHAR and length 1 for which 'X' and ' ' are defined as valid values in the domain, the parameter automatically appears as a checkbox on the selection screen.
    REPORT DEMO.
    PARAMETERS: A AS CHECKBOX,
    B AS CHECKBOX DEFAULT 'X'.
