How to get row number in the fetch row itself in Sql Query ?

Hi,
i am fetching some rows from a sql query . Is there any way to get row number as well in each row while all rows are fetched ?
like this :
RowNum data1 data2
1 abc ere
2 bnh ioi

Hello
Ofcourse you can get the rownum inside a query, just keep in mind that the rownum is the number of order in which the records were fetched from the table, so if you do an order by, the rownum will not be sequential, unless you query the information in a subquery first.
SELECT rown, col1, col1
FROM table
Or
SELECT rownum, col1, col2
FROM (SELECT col_1, col_2 FROM table ORDER BY col1)

Johan

How to get page number from the PDF using Javascript

Hi,
We are having list of Single page PDF. The pdf are named in the order,
ISBN_Author_01.PDF (with real page number as i)
ISBN_Author_02.PDF (with real page number as ii)
ISBN_Author_03.PDF (with real page number as iii)
ISBN_Author_04.PDF (with real page number as 1)
ISBN_Author_05.PDF (with real page number as 2)
ISBN_Author_06.PDF (with real page number as 3)
ISBN_Author_nn.PDF (with real page number as 500)
Here each pdf has a page number and in sequential order.
The task is to check whether all the pdfs are in sequential order (i.e i, ii, iii, 1, 2, 3). If any page is missing, the script should throw an error report.
To do this task, I am writing a Javascript to get the real page number from the PDF.
Can anybody help me how to get the page number from the PDF using Javascript.
Thanks,
Gopal

The "real" page number within a PDF is the count of the physical page starting at 0, zero.
pageNum numPages
The number printed on each page is the page label.
setPageLabels getPageLabel
You will have to open each PDF and your script would need to know the page label for that file. I would expect you would need to build a 2 dimensional array of the file names and the page label for the page within that array.

How to get physical number of selected row on the screen.

Hi,
We have block defined with Numbers of Records Displayed = 3. In the same time the data set contains 10 records. We would like to know how to get a number of row selected on the screen. i.e. in our case that the number will be always between 1 and 3 independent of the current row position in the data set.
Best regards,
Constantin.

You can calculate that number by subtracting :SYSTEM.CURSOR_RECORD and GET_BLOCK_PROPERTY('BLOCK', TOPMOST_RECORD)

How to get a question in the course placed anywhere in the course and does not appear in the quiz result or total number of questions. Pretest would work except it can't go anywhere in the course (at least for me it can't)

How to get a question in the course placed anywhere in the course and does not appear in the quiz result or total number of questions. Pretest would work except it can't go anywhere in the course (at least for me it can't)

Use a normal question, and do not add the score to the total score. That will give you a correct score at the end. But the total number of questions, that system variable will still take into account all questions. You'll need a user variable, and calculate its value by subtracting 1 from the system variable cpQuizInfoTotalQuestionsPerProject. Same for the progress indicator if you want to show it?
Customized Progress Indicator - Captivate blog
If you want to allow Review, you'll have to tweak as well. You didn't specify the version, and all those questions I now mentioned.
And my approach, since you talk about only one question: create a custom question, because you'll have total control then.

TableView -- get the row number of the top most current visible row

Is there any way to get the row number of the top most visible row, and or bottom most visible row in TableView?

If you already know the document's name, the sheet's name and the table's name, the easy way is :
--Here you may replace the three values by the current ones
set dName to 1
set sName to 1
set tName to 1
tell application "Numbers" to tell document dName to tell sheet sName to tell table tName
tell first cell of the selection range to set {rowNum1, columnNum1} to {address of its row, address of its column}
tell last cell of the selection range to set {rowNum2, columnNum2} to {address of its row, address of its column}
end tell

How to get thr number of rows of an SQL query in JSTL

hi guys,
can anyone please tell me how do i perform a function which finds out the particular rownumber of an sql query in JSTL.....
the same code in jsp is:
<% plateRSet.getRowNum() %>
how do i do this given plateRset is the var for a given iteration
thanks
rahul

make your result set scrollable...Not such a good idea. With Oracle, the JDBC driver will read and cache all the ResultSet in memory (with other DBMSs/drivers the behavior will probably be different, but you will still have some unnecessary overhead).
You can do the caching yourself if you think it's worth it. If the piece of code you posted is why you need this for, then use a List or Vector and you won't need to know the size upfront.

Row number in the table.

Hi:
How can get the row number in its table?
For example:
I have table a:
a1-a2
5---a
2---b
7---c
3---d
I want for a1 value 7, I want to get 3 (the row number in the table).
Regards
Saad

> You know there is ROWID, is there a way to know row number in the table by ROWID?
No. ROWID is the physical address of the row. It specifies the location of the row on disk. Nothing more. There is no numbering involved.
> Should there is a way, because there is some programs deal with the table row as it in
the table.
These programs are wrong.
> Ok, I have a software (SmartCodeStudio) which deal with the database to print rows from
a table but he deals with "record" which is row number in the table
Wrong, wrong, wrong. A RDBMS is not a binary flat file. A row in a relational table is identified by its primary key. Period.
There seems to be nothing smart about SmartCodeStudio if it is not capable of dealing with a relational design, and primary key identifiers.

How to get paragraph number of selected text in ID CS4

Hi,
Can anybody help me how to get paragraph number of selected text in Indesign cs4.
Thanks,
Gopal

Ah, I see -- thanks. Turns out that there's no difference in speed between texts.itemByRange(), characters.itemByRange(),and insertionPoints.itemByRange(). In a document with 170 pages of text, and with the cursor in the last paragraph, the second and third lines, below (and your function), give exactly the same result:
t = app.selection[0];
t.parentStory.texts.itemByRange (t.parentStory.insertionPoints[0], t).paragraphs.length;
t.parentStory.characters.itemByRange (t.parentStory.characters[0], t).paragraphs.length;

Hi deva,
write a class which implemets these methods
CLASS lcl_event_receiver DEFINITION.
PUBLIC SECTION.
    METHODS:
To handle the toolbar on alv
     handle_toolbar
       FOR EVENT toolbar OF cl_gui_alv_grid
          IMPORTING e_object e_interactive,
To handle the buttons on the alv grid
     handle_user_command
       FOR EVENT user_command OF cl_gui_alv_grid
       IMPORTING e_ucomm.
endclass.
Now Implement these methods.
CLASS lcl_event_receiver IMPLEMENTATION.
To handle the toolbar on alv
METHOD handle_toolbar.
   DATA ls_toolbar TYPE stb_button.
    CLEAR gs_toolbar.
    MOVE 3 TO gs_toolbar-butn_type.
    APPEND gs_toolbar TO e_object->mt_toolbar.
    CLEAR gs_toolbar.
    PERFORM icon_create USING 'ICON_INSERT_ROW' gs_toolbar-icon.
    MOVE text-010 TO gs_toolbar-function.
    MOVE text-012 TO gs_toolbar-quickinfo.
    MOVE ' ' TO gs_toolbar-disabled.
    APPEND gs_toolbar TO e_object->mt_toolbar.
    CLEAR gs_toolbar.
    PERFORM icon_create USING 'ICON_DELETE_ROW' gs_toolbar-icon.
    MOVE text-011 TO gs_toolbar-function.
    MOVE text-013 TO gs_toolbar-quickinfo.
    MOVE ' ' TO gs_toolbar-disabled.
    APPEND gs_toolbar TO e_object->mt_toolbar.
ENDMETHOD.
   METHOD handle_user_command.
In this form, check the function code(e_ucomm has the function code), based on that do the required action.
as i said yesterday(i.e for appending a row, deleting a row, modifying a row)
    PERFORM user_command USING e_ucomm.
ENDMETHOD
endclass.
Before calling the alv method, create a object of this class.
DATA :
      gref_event_receiver TYPE REF TO lcl_event_receiver,
      gv_tables_alv          TYPE REF TO cl_gui_alv_grid.
      CREATE OBJECT gref_event_receiver.
      SET HANDLER   gref_event_receiver->handle_user_command
                    FOR gv_tables_alv.
      SET HANDLER   gref_event_receiver->handle_toolbar
                    FOR gv_tables_alv.
check this program for event handling, it is the similar way
demo_abap_objects_events
Hope u understood this.

Prasant
